Curcumin for amyloidosis and lipid metabolism -- a novel insight
Shinshu University (Japan), February 26, 2021
Curcumin is a polyphenol compound produced by plants of the Curcuma longa species and has been reported to have many physiological activities, which include anti-oxidation, anti-inflammatory, anti-cancer, and anti-amyloid properties. However, the mechanism and network of action are not completely clear. Amyloidosis is a group of diseases characterized by abnormal aggregates of proteins, known as amyloid fibrils, and subsequent deposition in various tissues and organs, such as Alzheimer's disease, immunoglobulin light chain amyloidosis.
In previous studies, curcumin has been shown to suppress the aggregation and cytotoxicity of many amyloid proteins in vitro, such as amyloid ß (Aß), α-synuclein, transthyretin, and prion protein, and has also been reported to inhibit the deposition of Aß fibrils in a mouse model of Alzheimer's disease. The group investigated amyloid deposition and molecular changes in a mouse model of amyloid apolipoprotein A-II (AApoAII) amyloidosis, in which mice were fed a curcumin-supplemented diet. In this research, it was found that curcumin intake elevated ApoA-II and HDL-cholesterol concentration in plasma by activating the peroxisome proliferator-activated receptor alpha (PPARα) signaling pathway, resulting in increased AApoAII amyloid deposition and peroxisome proliferation. These findings demonstrate the novel agonistic effect of curcumin on PPARα, which is an important transcription factor for lipid metabolism, and may have far-reaching significance for the treatment of amyloidosis and other metabolic disorders.
It was reported that high-fat diet supplement aggravates a variety of amyloid deposition including Aß in Alzheimer's disease model mice, but a link between lipid metabolism and the development of amyloidosis has not been completely established. These results provide a promising molecular target to understand the molecular mechanism of amyloidogenesis, which the activation state of PPARα pathway may be a bridge to connect the change of lipid metabolism level and the degree of amyloid deposition. In addition, it has been regarded that curcumin, as an agonist of PPARγ, exerts anti-inflammatory, anti-cancer and antioxidant activities in the past. However, this study demonstrates that curcumin is a PPARα/γ dual activator and may affect expression levels of proteins involved in amyloid deposition and other metabolism functions in a complex manner. By focusing on the PPARα pathway, the group hope to provide an opportunity to reconsider the mechanism of the physiological effects of curcumin.
In the next stage, the group would like to clarify how curcumin activates the PPARα signaling pathway in vitro and confirm whether the activation of PPARα can affect amyloid deposition on other types of amyloidosis in vivo (Alzheimer's disease, ATTR amyloidosis etc.). The goal in this research is to elucidate the molecular pathways involved in the pathogenesis of amyloidosis in vivo and to develop effective therapeutic or preventive methods against the development of amyloidosis. As a future study, the group hopes to fully understand the molecular fluctuations of PPARα-activated cells and verify the effectiveness of interventions in these pathways for various metabolic diseases.
 
 
Older women who ate more plant protein had lower risk of premature, dementia-related death
University of Iowa, February 24, 2021 
Postmenopausal women who ate high levels of plant protein had lower risks of premature death, cardiovascular disease and dementia-related death compared with women who ate less plant proteins, according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association.
Previous research has shown an association between diets high in red meat and cardiovascular disease risk, yet the data is sparse and inconclusive about specific types of proteins, the study authors say.
In this study, researchers analyzed data from more than 100,000 postmenopausal women (ages 50 to 79) who participated in the national Women's Health Initiative study between 1993 and 1998; they were followed through February 2017. At the time they enrolled in the study, participants completed questionnaires about their diet detailing how often they ate eggs, dairy, poultry, red meat, fish/shellfish and plant proteins such as tofu, nuts, beans and peas. During the study period, a total of 25,976 deaths occurred (6,993 deaths from cardiovascular disease; 7,516 deaths from cancer; and 2,734 deaths from dementia).
Researchers noted the levels and types of protein women reported consuming, divided them into groups to compare who ate the least and who ate the most of each protein. The median percent intake of total energy from animal protein in this population was 7.5% in the lowest quintile and 16.0% in the highest quintile. The median percent intake of total energy from plant protein in this population was 3.5% in the lowest quintile and 6.8% in the highest quintile.
Among the key findings:
Compared to postmenopausal women who had the least amount of plant protein intake, those with the highest amount of plant protein intake had a 9% lower risk of death from all causes, a 12% lower risk of death from cardiovascular disease and a 21% lower risk of dementia-related death.
Higher consumption of processed red meat was associated with a 20% higher risk of dying from dementia.
Higher consumption of unprocessed meat, eggs and dairy products was associated with a 12%, 24% and 11% higher risk of dying from cardiovascular disease, respectively.
Higher consumption of eggs was associated with a 10% higher risk of death due to cancer.
However, higher consumption of eggs was associated with a 14% lower risk of dying from dementia, while higher poultry consumption was associated with a 15% lower risk.
"It is unclear in our study why eggs were associated with a higher risk of cardiovascular and cancer death," said lead study author Wei Bao, M.D., Ph.D., an assistant professor of epidemiology at the University of Iowa in Iowa City. "It might be related to the way people cook and eat eggs. Eggs can be boiled, scrambled, poached, baked, basted, fried, shirred, coddled or pickled or in combinations with other foods. In the United States, people usually eat eggs in the form of fried eggs and often with other foods such as bacon. Although we have carefully accounted for many potential confounding factors in the analysis, it is still difficult to completely tease out whether eggs, other foods usually consumed with eggs, or even non-dietary factors related to egg consumption, may lead to the increased risk of cardiovascular and cancer death."
Researchers noted that substitution of total red meat, eggs or dairy products with nuts was associated with a 12% to 47% lower risk of death from all causes depending on the type of protein replaced with nuts.
"It is important to note that dietary proteins are not consumed in isolation, so the interpretation of these findings could be challenging and should be based on consideration of the overall diet including different cooking methods," said Yangbo Sun, M.D., Ph.D., co-author of the study, a postdoctoral research scholar at the University of Iowa in Iowa City and currently an assistant professor of epidemiology at the University of Tennessee Health Science Center.
The analysis also revealed that women who ate the highest amount of animal protein such as meat and dairy were more likely to be white and have a higher education and income, and they were more likely to be past smokers, drink more alcohol and be less physically active. Moreover, these women were more likely to have Type 2 diabetes at the start of the study, a family history of heart attacks and a higher body mass index -- all risk factors for cardiovascular disease.
"Our findings support the need to consider dietary protein sources in future dietary guidelines," said Bao. "Current dietary guidelines mainly focus on the total amount of protein, and our findings show that there may be different health influences associated with different types of protein foods."
2020-2025 Dietary Guidelines for Americans, jointly published by the U.S. Departments of Agriculture (USDA) and Health and Human Services (HHS), recommend eating a variety of protein foods: low-fat meat, low-fat poultry, eggs, seafood, beans, peas, lentils, nuts, seeds and soy products including at least 8 ounces of cooked seafood per week.
The AHA's 2020 Dietary Cholesterol and Cardiovascular Risk advisory notes that given the relatively high content of cholesterol in egg yolks, it remains advisable to limit intake. Healthy individuals can include up to one whole egg or the equivalent daily.
The study had several limitations including that it was observational, based on self-reported data at the beginning of the study and lacked data on how the proteins were cooked. In addition, the findings may not apply to younger women or men.
 
 
Citrus Flavonoid May Help to Improve Metabolic and Inflammatory Markers
Sao Paulo State University (Brazil), February 20, 2021
The researchers from Sao Paulo State University and the US Horticultural Research Laboratory associated the citrus flavonoid with a significant reduction in levels of cholesterols and triglycerides which are markers of insulin resistance at low (10 and 25 mg/kg BW) and high ( 100 mg/kg BW) doses, with the best results being observed at 25 mg per kg of body weight. 
The study authors wrote, “Therefore, our results showed that low doses of dietary eriocitrin are able to counteract the deleterious effects of high-fat diet and prevent risk factors of metabolic syndrome and chronic disease related to obesity.” 
“Further, the use of lower doses may help to prevent unintended complications possibly occurring at much higher doses of potent antioxidant supplements such as eriocitrin.”
“As a leading supplier of citrus flavonoids, we put great importance into the continual development of research into these powerful ingredients,” said Rob Brewster who is the President of Ingredients by Nature (IBN). “Eriocitrin is not as commonly recognized as other fruit-derived flavonoids, but the science shows that it is a potent source of health support for a variety of health complications. We look forward to seeing what future research will continue to reveal about it.”
During this study 40 male mice were fed a high-fat diet for 4 weeks to induce obesity, then they were divided at random into four different groups for an additional 4 weeks and given doses of eriocitrin at 0, 10, 25, or 100 mg per kg of body weight, while a control group was fed a standard diet for the 8 weeks. 
The researchers reported the best results being observed in the eriocitrin group taking 25 mg/kg with reductions in triglycerides of 31%, total cholesterol of 6%, and liver triacylglycerols of 28% compared to the control group. Eriocitrin at 25 mg/kg was associated with a reduction in lipid peroxidation of 19%, and markers of insulin resistance including resistin and the insulin resistance index also significantly decreased. Additionally, serum glucose levels also significantly decreased by 25%, insulin levels by 35% in this same group. 
“Most studies on eriocitrin haven’t explored its effect on obesity induces metabolic disturbances and, because the global rate of obesity continues to increase, we felt that it was important to examine the topic further,” said the corresponding author Dr. Thais Cesar who is also an associate professor of nutrition at Sao Paulo State University. “Eriocitrin significantly improved metabolic, inflammatory, and oxidative stress parameters across multiple biomarkers, showing potential to delay the development of inflammatory complications. We look forward to performing additional research on eriocitrin in the future.”
This study was sponsored by IBM, and also showed that eriocitrin was effective in terms of glucose and lipid metabolism, especially with blood glucose reduction, along with delivering a strong antioxidant defense by directly helping the uptake of oxygen radicals and promoting the activation of endogenous defense mechanisms. This effect has been reported in previous studies including with the lemon flavonoid blend Eriomin, which is made up primarily of eriocitrin. Last year, the company also received patent approval from the USPTO for IBN’s use of eriocitrin as a method of reducing blood glucose levels
 
Resveratrol may be an effective intervention for lung aging
The Saban Research Institute (Los Angeles), February 22, 2021
 
In a study led by Barbara Driscoll, PhD, of The Saban Research Institute of Children's Hospital Los Angeles, researchers demonstrate, for the first time that inhaled resveratrol treatments slow aging-related degenerative changes in mouse lung. Lung aging, characterized by airspace enlargement and decreasing lung function, is a significant risk factor for chronic human lung diseases. The study is published online in the journal Thorax.
 
"We believe that ours is the first study to demonstrate a beneficial effect of lung-directed resveratrol treatments on aging lung function," said Driscoll.
 
Resveratrol (RSL), a chemical found in red wine, is an antimicrobial chemical substance produced by plants to protect against infection and stress-related changes. It has previously been shown to support muscle metabolism when delivered orally.
 
RSL prophylaxis by inhalation was a novel measure taken by the research team as a potential approach for slowing age-related deterioration of lung function and structure by preserving alveolar epithelial type 2 cells (AEC2) which line alveoli (the tiny air sacs in the lungs through which the exchange of oxygen and carbon dioxide takes place) and produce surfactant which is vital for efficient breathing.
 
In healthy young adults, breathing is an essential, efficient process, but natural aging of the lung occurs at a steady and irreversible rate, as measured by a decline in lung function. This natural deterioration leads to a significantly reduced quality of life, over a time frame dependent on genetic and environmental factors. Although some available therapies can ameliorate symptoms, aging-related lung failure is generally irreversible and is accompanied by high rates of morbidity and mortality due to increased disease risk, including development of COPD, with accompanying emphysema and chronic bronchitis.
 
Using a rapidly aging mouse model, the research team investigated whether the accumulation of age-related degenerative changes in the lung could be slowed by inhaled RSL. Treatment cohorts received either RSL or vehicle by intratracheal (IT) instillation monthly for three months. One month following the final treatment, whole lung function and injury-related gene expression in AEC2 were assessed.
 
The research team found that inhaled, prophylactic resveratrol treatments can slow the rate of lung function decline, alveolar enlargement and alveolar epithelial type 2 cell DNA damage that occurs in the early stages of lung aging. They concluded that administration of resveratrol directly to the lungs may be an effective intervention for lung aging, which is a significant risk factor for development of chronic lung disease.
 
"While the natural deterioration of the human lung generally occurs over decades, the injury to lung cells is analogous to the lung cell damage that occurs in premature infants who experience respiratory distress before their lungs have fully developed," added Driscoll. "Identifying a way to protect and strengthen young lungs before significant damage occurs is the goal of our research."
 
 
Deficient magnesium levels prevalent in an older population
Kathmandu Medical College (Nepal), February 19, 2021
According to news reporting out of Kathmandu Medical College research stated, “Magnesium deficiency is common in the elderly and critically ill population and has been associated with a prolonged ICU stay. The knowledge of hypomagnesemia is essential as it could have prognostic and therapeutic implications in the elderly population.”
The news correspondents obtained a quote from the research from Kathmandu Medical College: “This study aimed to estimate the prevalence of hypomagnesemic in the elderly population visiting a tertiary care center. This descriptive cross-sectional study was conducted in a tertiary care hospital from March 21, 2020 to September 21, 2020. After obtaining ethical clearance from the institutional review committee (Ref. 2003202008), convenience sampling was done. Data were collected and entered in Microsoft Excel version 2007. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. Out of 384 participants, 174 (45%) participants were found to have deranged magnesium levels, in which 111 (29%) (31.3-26.7 at 95% Confidence Interval) were found to be hypomagnesemia. Among them, 62 (29.4%) males and 49 (28.5%) females were hypomagnesemia. The average level of serum magnesium was 2.02±0.76 mg/dl ranging from 0.03 to 4.71. The mean age of participants was 70.31±8.13 years, among which the participants between the age group of 71-80 years presented with a maximum percentage of hypomagnesemia.”
According to the news reporters, the research concluded: “The present study has shown that an apparently-healthy elderly population may have a magnesium deficiency that may need to be identified and treated for optimizing clinical care. Further multicentric studies with a greater sample size should be done in this field, which will benefit the elderly population.”
 
 
Researchers identify mechanism by which exercise strengthens bones and immunity
University of Texas Medical Center, February 24, 2021
Scientists at the Children's Medical Center Research Institute at UT Southwestern (CRI) have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study, published in Nature, also shows that movement-induced stimulation is required for the maintenance of this niche, as well as the bone and immune-forming cells that it contains. Together, these findings identify a new way that exercise strengthens bones and immune function.
Researchers from the Morrison laboratorydiscovered that forces created from walking or running are transmitted from bone surfaces along arteriolar blood vessels into the marrow inside bones. Bone-forming cells that line the outside of the arterioles sense these forces and are induced to proliferate. This not only allows the formation of new bone cells, which helps to thicken bones, but the bone-forming cells also secrete a growth factor that increases the frequency of cells that form lymphocytes around the arterioles. Lymphocytes are the B and T cells that allow the immune system to fight infections.
When the ability of the bone-forming cells to sense pressure caused by movement, also known as mechanical forces, was inactivated, it reduced the formation of new bone cells and lymphocytes, causing bones to become thinner and reducing the ability of mice to clear a bacterial infection. 
"As we age, the environment in our bone marrow changes and the cells responsible for maintaining skeletal bone mass and immune function become depleted. We know very little about how this environment changes or why these cells decrease with age," says Sean Morrison, Ph.D., the director of CRI and a Howard Hughes Medical Institute Investigator. "Past research has shown exercise can improve bone strength and immune function, and our study discovered a new mechanism by which this occurs."
Previous work from the Morrison laboratory discovered the skeletal stem cells that give rise to most of the new bone cells that form during adulthood in the bone marrow. They are Leptin Receptor+ (LepR+) cells. They line the outside of blood vessels in the bone marrow and form critical growth factors for the maintenance of blood-forming cells. The Morrison lab also found that a subset of LepR+ cells synthesize a previously undiscovered bone-forming growth factor called Osteolectin. Osteolectin promotes the maintenance of the adult skeleton by causing LepR+ to form new bone cells.
In the current study, Bo Shen, Ph.D., a postdoctoral fellow in the Morrison laboratory, looked more carefully at the subset of LepR+ cells that make Osteolectin. He discovered that these cells reside exclusively around arteriolar blood vessels in the bone marrow and that they maintain nearby lymphoid progenitors by synthesizing stem cell factor (SCF) - a growth factor on which those cells depend. Deleting SCF from Osteolectin-positive cells depleted lymphoid progenitors and undermined the ability of mice to mount an immune response to bacterial infection.
"Together with our previous work, the findings in this study show Osteolectin-positive cells create a specialized niche for bone-forming and lymphoid progenitors around the arterioles. Therapeutic interventions that expand the number of Osteolectin-positive cells could increase bone formation and immune responses, particularly in the elderly," says Shen.
Shen found that the number of Osteolectin-positive cells and lymphoid progenitors decreased with age. Curious if he could reverse this trend, Shen put running wheels in the cages so that the mice could exercise. He found the bones of these mice became stronger with exercise, while the number of Osteolectin-positive cells and lymphoid progenitors around the arterioles increased. This was the first indication that mechanical stimulation regulates a niche in the bone marrow. 
Shen found that Osteolectin-positive cells expressed a receptor on their surfaces - known as Piezo1 - that signals inside the cell in response to mechanical forces. When Piezo1 was deleted from Osteolectin-positive cells of mice, these cells and the lymphoid progenitors they support became depleted, weakening bones and impairing immune responses.
"We think we've found an important mechanism by which exercise promotes immunity and strengthens bones, on top of other mechanisms previously identified by others," says Morrison.
 
Long-term iodine nutrition associated with longevity in older adults: a 20 year follow-up of the Randers-Skagen Study
Aalborg University (Denmark), February 23, 2021
According to news reporting originating in Aalborg, Denmark, research stated, “Iodine intake affects the occurrence of thyroid disorders. However, the association of iodine intake with longevity remains to be described.”
The news reporters obtained a quote from the research from Aalborg University Hospital, “This led us to perform a 20 years’ follow-up on participants from the Randers-Skagen (RaSk) study. Residents in Randers born in 1920 (n 210) and Skagen born in 1918-1923 (n 218) were included in a clinical study in 1997-1998. Mean iodine content in drinking water was 2 mu g/l in Randers and 139 mu g/l in Skagen. We collected baseline data through questionnaires, performed physical examinations and measured iodine concentrations in spot urine samples. Income data were retrieved from Danish registries. We performed follow-up on mortality until 31 December 2017 using Danish registries. Complete follow-up data were available on 428 out of 430 of participants (99 center dot 5 %). At baseline, the median urinary iodine concentration was 55 mu g/l in Randers and 160 mu g/l in Skagen residents. Participants were long-term residents with 72.8 and 92.7 % residing for more than 25 years in Randers and Skagen, respectively. Cox regression showed that living in Skagen compared with Randers was associated with a lower hazard ratio (HR) of death in both age- and sex-adjusted analyses (HR 0.60, 95 % CI 0.41, 0.87, P = 0.006), but also after adjustment for age, sex, number of drugs, Charlson co-morbidity index, smoking, alcohol and income (HR 0.60, 95 % CI 0.41, 0.87, P = 0.008). Residing in iodine-replete Skagen was associated with increased longevity.”
According to the news reporters, the research concluded: “This indicates that long-term residency in an iodine-replete environment may be associated with increased longevity compared with residency in an iodine-deficient environment.”
This research has been peer-reviewed.

The effects of lycopene supplementation on serum insulin-like growth factor 1 (IGF-1) levels and cardiovascular disease
Ganzhou People’s Hospital (China), February 22, 2021
 
The results of human studies assessing the efficacy of lycopene on insulin-like growth factor 1 (IGF-1) levels are inconsistent. Thus, we performed a systematic review and meta-analysis to examine the effects of lycopene supplementation on serum IGF-1 levels and cardiovascular disease.
Methods
The literature published up to January 2020 was searched using the electronic databases Scopus, PubMed/Medline, Web of Science, Embase and Google Scholar.
Results
Seven qualified trials were included in the current meta-analysis. IGF-1 levels were non-significantly decreased in lycopene group compared to the control (WMD: −6.74 ng/mL, 95 % CI: −23.01 to 9.52, p = 0.42; I2 = 94.3 %). Subgroup analysis revealed a significantly decrease in IGF-1 levels upon lycopene supplementation at doses ≥15 mg/d (WMD: −6.40 ng/mL), intervention period 15 mg/d, for

French maritime pine bark supplementation associated with improvements in diabetes complications
Tabriz University of Medical Sciences (Iran), February 24 2021. 
 
A randomized trial reported on February 18, 2021 in Complementary Therapies in Medicine resulted in improvement of several factors related to type 2 diabetes among men and women who were given supplements containing French maritime pine bark extract.
The trial included 46 diabetics between the ages of 30 and 65 years who were recruited from March 2018 to April 2019. Participants received two capsules that provided 50 milligrams each of French maritime bark extract or a placebo daily for eight weeks. Diet and medication use remained unchanged throughout the trial. Anthropometric factors, glycemic parameters, lipids and factors related to inflammation and kidney function were assessed at the beginning and end of the study. 
At eight weeks, waist circumference, waist to height ratio, hemoglobin A1c, total cholesterol, vascular cell adhesion molecule 1 (VCAM-1, an inflammatory cell that contributes to atherosclerosis), and urinary albumin to creatinine ratio (an early indicator of kidney disease) were lower at the end of the study among participants who received French maritime pine bark extract in comparison with the placebo. Serum fasting blood glucose levels were also lower at the end of the study in the group that received the extract; however, the reduction was not considered significant. 
“There is a growing body of evidence that suggests pine bark extract supplementation has some potentially beneficial metabolic properties such as anti-diabetic and hypoglycemic effects,” Elham Navval-Esfahlan and colleagues wrote.
“The present study indicated that daily supplementation with 100 mg of pine bark extract in patients with type 2 diabetes mellitus and microalbuminuria had favorable effects on glycemic control, serum VCAM-1, and urinary albumin to creatine ratio level, as well as total cholesterol concentrations and abdominal obesity which could be helpful in the control of diabetes complications,” they concluded. 
 
 
 
Study finds association between supplementing with zinc and lower risk of Alzheimer's disease
University of Manchester (UK), February 22 2021. 
 
An epidemiologic study conducted at the University of Manchester found an association between zinc supplementation and a decreased risk of Alzheimer's disease as well as a reduction in the progression of cognitive decline in Alzheimer's disease patients. It was additionally determined that zinc deficiency accelerated memory deficits in an Alzheimer's disease mouse model compared to a control group, due to increased inflammation. The findings were reported in an article appearing on February 17, 2021 in the Journal of Neuroscience.
For the epidemiologic study, Jack Rivers-Auty and his associates utilized data from the Alzheimer’s Disease Neuroimaging Initiative database, which included 1,631 men and women who were cognitively normal or diagnosed with mild cognitive impairment or early Alzheimer's disease. Subjects were evaluated upon enrollment, at six and 12 months, and yearly thereafter. Data obtained at the beginning of the study provided information concerning the use of nutritional supplements. 
Among those who reported supplementing with zinc, just 6% were diagnosed with Alzheimer's disease, in contrast with 26% of those who reported no supplement use. Calcium, iron and magnesium also appeared to be protective. Zinc use was additionally associated with a less rapid rate of cognitive decline during up to ten years of follow-up. 
Giving mice zinc deficient diets was associated with increased cognitive decline due to enhanced NLRP3-driven inflammation, which was reversed by giving the animals diets that contained a normal amount of zinc. “These data suggest that zinc deficiency is causally accelerating cognitive decline in Alzheimer’s disease and that these cognitive deficits are reversible,” Dr Rivers-Auty and colleagues wrote. 
“This research suggests that zinc status is linked to inflammatory reactivity and may be modified in people to reduce the risk and slow the progression of Alzheimer’s disease,” they concluded.
 
 
Study finds low folate, vitamin B12 associated with worse cognitive function
University of Massachusetts, February 22, 2021
 
According to news reporting from Lowell, Massachusetts, research stated, “There is evidence that low plasma vitamin B-12 and folate individually, as well as an imbalance of high folic acid and low vitamin B-12 status, may be associated with lower cognitive function. We examined dietary and plasma folate and vitamin B12 status, and their interaction, in relation to cognitive function in a cohort of older Puerto Rican adults.”
The news correspondents obtained a quote from the research from the University of Massachusetts Lowell, “The design is cross-sectional, with 1408 participants from the Boston Puerto Rican Health Study (mean SD age: 57.1 +/- 7.9 y). Cognitive function was assessed with a comprehensive test battery and a global composite score was derived. Plasma folate, vitamin B12, and methylmalonic acid (MMA) were assessed in fasting blood samples. After adjusting for covariates, high plasma folate and high plasma vitamin B-12 were each positively associated with global cognitive score (beta: 0.063; 95% CI: -0.0008, 0.127; P = 0.053 and beta: 0.062; 95% CI: 0.009, 0.12; P = 0.023, respectively, for logged values, and beta: 0.002; 95% CI: 0.00005, 0.004; P-trend = 0.044 and beta: 0.00018; 95% CI: 0.00001, 0.0003; P-trend = 0.036, respectively, across tertiles). Nine percent of participants had vitamin B-12 deficiency (plasma vitamin B-12 148 pmol/L or MMA 271 nmol/L), but none were folate deficient (plasma folate < 4.53 nmol/L). Deficient compared with higher vitamin B-12 was significantly associated with lower cognitive score (beta: -0.119; 95% CI: -0.208, -0.029; P = 0.009). We could not examine the interaction for vitamin B-12 deficiency and high plasma folate, because there were too few individuals (

L-theanine improves neurophysiologic measures of attention in dose-dependent manner University of Peradeniya (Sri Lanka), February 22, 2021 According to news reporting originating from Peradeniya, Sri Lanka,research stated, “L-theanine, a non-proteinic amino acid found in tea, is known to enhance attention particularly in high doses, with no reported adverse effects. We aimed to determine whether oral administration of L-theanine acutely enhances neurophysiological measures of selective attention in a dose-dependent manner.” Our news editors obtained a quote from the research from the University of Peradeniya, “In a double-blind, placebo-controlled, counterbalanced, 4-way crossover study in a group of 27 healthy young adults, we compared the effects of 3 doses of L-theanine (100, 200 and 400 mg) with a placebo (distilled water) on latencies of amplitudes of attentive and pre-attentive cognitive event-related potentials (ERPs) recorded in an auditory stimulus discrimination task, before and 50 min after dosing. Compared to the placebo, 400 mg of theanine showed a significant reduction in the latency of the parietal P3b ERP component (p < 0.05), whereas no significant changes were observed with lower doses. A subsequent exploratory regression showed that each 100-mg increase in dose reduces the P3b latency by 4 ms (p < 0.05). No dose-response effect was observed in P3b amplitude, pre-attentive ERP components or reaction time. The findings indicate L-theanine can increase attentional processing of auditory information in a dose-dependent manner.” According to the news editors, the research concluded: “The linear dose-response attentional effects we observed warrant further studies with higher doses of L-theanine.” This research has been peer-reviewed.
 
Lost your appetite? Nutmeg oil can bring it back Kyoto University (Japan), February 21 2021 Loss of appetite is treated by directly addressing its cause. However, depending on the condition it’s associated with, treatment can be expensive. But in a recent study, researchers at Kyoto University investigated a potential treatment for loss of appetite that’s both inexpensive and easy to administer. Myristica fragrans, from which this natural medicine is derived, is an evergreen tree native to the Moluccas, or Spice Islands, of Indonesia. The seeds of this exotic plant are the main source of two popular culinary spices, namely, nutmeg and mace. According to previous studies, the oil derived from the fruits and seeds of the nutmeg tree has appetite-enhancing properties. Nutmeg oil is also traditionally used to treat digestive issues, such as bloating, gastrointestinal distress and decreased appetite. The researchers explored the beneficial properties and active components of nutmeg oil in an article published in the Journal of Natural Medicines. Nutmeg oil shows appetite-enhancing effects in vivo The spice known as nutmeg is popular for its warm, nutty flavor that goes well with sweet and savory dishes. It is widely used today in the culinary world and can be found in almost every kitchen around the world. In Asian countries, nutmeg is not only used as an ingredient, but it also has a long history of use as herbal medicine that can improve a person’s appetite. (Related: Nutmeg exhibits powerful anti-diabetes properties, concludes study.) According to previous studies, nutmeg oil contains two active phytochemicals, myristicin and methyl eugenol. Myristicin is also present in parsley, black pepper, carrots and dill, and is said to have anti-inflammatory, antibacterial, antioxidant, anti-proliferative, anti-cholinergic and hepatoprotective properties. Methyl eugenol, meanwhile, is a compound present in various essential oils. It has been reported to have antibacterial, antifungal, insecticidal, anesthetic and antioxidant properties. In one animal study, researchers found that inhalation of myristicin and methyl eugenol increased the appetite mice. Because of this, the two compounds have attracted the attention of healthcare professionals who care for older people with dementia. Loss of appetite is not unusual for these patients since they tend to suffer from hypophagia, or a reduction in food intake and feeding behavior. Hypophagia, if left unaddressed, leads to frailty, and patients end up bedridden. Hence, inexpensive appetite-enhancing agents that are easy to administer are particularly desirable. In their study, the Japanese researchers found that inhalation of nutmeg oil, myristicin and methyl eugenol produced appetite-enhancing effects in mice. However, only methyl eugenol exerted both appetite-enhancing and locomotor-reducing effects at the same dose. According to a previous study, benzylacetone, an attractant compound found abundantly in flowers, also exerted the same effects at the same dose, and even increased the bodyweight of mice significantly. Methyl eugenol, however, did not have the same effect on body weight because the mice experienced olfactory habituation — reduced behavioral response due to repeated exposure — after several inhalations. The researchers believe that their study provides crucial information for identifying suitable compounds that can be used for the long-term treatment of appetite loss.
 
Case Study Shows Cannabis Led To Remarkable Improvement In Childhood Autism Symptoms Caleo Health Clinic (Canada) and Alberta Children's Hospital, February 21, 2021 An extremely promising case study was recently published in the Journal of Medical Case Reports illustrating the positive effects of cannabis extract and its association with improved autism related behavioral symptoms. According to the authors, “the pharmacological treatment for autism spectrum disorders is often poorly tolerated and has traditionally targeted associated conditions, with limited benefit for the core social deficits. We describe the novel use of a cannabidiol-based extract that incidentally improved core social deficits and overall functioning in a patient with autism spectrum disorder, at a lower dose than has been previously reported in autism spectrum disorder.” The case study focused on a child with autism who was switching out prescription seizure medicine for his epilepsy with a very low cannabidiol-based extract dose. The study found that not only did the cannabidiol extract help with his seizures, but he also “experienced unanticipated positive effects on behavioral symptoms and core social deficits,” according to the study. Researchers pointed out that to modify disruptive behaviors and improve social communication skills, often times children with autism are prescribed psychopharmacologic medications that target specific ASD core behaviors (for example, repetitive behaviors) and associated behaviors (for example, hyperactivity, aggression, anxiety, and sleep disturbances), but do not treat core social communication deficits. They explain that these medications are known for producing “substantial side effects.” For example, aripiprazole and risperidone, the only two medications approved by the US Food and Drug Administration (FDA) to treat irritability and agitation in ASD, frequently cause somnolence, increased appetite, and weight gain. These factors have led to families seeking alternative treatments outside of the psychopharmacologic realm. One of the newest forms of these alternative medicines is cannabidiol-based extract. Researchers reported that the patient’s symptoms improved within six-months of treatment, and that he has maintained “positive effects on his behavioral symptoms, anxiety, sleep, and social deficits” since that time. The results of CBE treatments, according to the case study, were nothing short of remarkable. He became more motivated and energetic, starting his own vegetarian diet and exercise programs, ultimately losing 6.4 kg after starting CBE for a calculated BMI of 21.33 kg/m2. He was able to start his first part-time job helping customers and interacting with them. He was instructed to fill out the self-administered Adult AQ which resulted in a normal score of 10. His mother stated he now also has a girlfriend. “This case report provides evidence that a lower than previously reported dose of a phytocannabinoid in the form of a cannabidiol-based extract may be capable of aiding in autism spectrum disorder-related behavioral symptoms, core social communication abilities, and comorbid anxiety, sleep difficulties, and weight control,” authors concluded. “Further research is needed to elucidate the clinical role and underlying biological mechanisms of action of cannabidiol-based extract in patients with autism spectrum disorder.” According to a report in Norml, these finding back up previous research published last year by investigators at Tufts University in Boston who similarly reported that the oral administration of cannabis-based products is associated with improvements in autistic symptoms in patients with self-injurious behaviors and co-morbid epilepsy, Several small clinical trials – such as those reported here, here, here, and here – have also previously reported that plant-derived cannabis extracts are effective and well-tolerated in mitigating various symptoms in patients with ASD, including hyperactivity, seizures, anxiety, and rage attacks.
 
High Homocysteine Levels May Increase Risk Of Heart Attack, Stroke, & Alzheimer’s Disease Temple University, February 14, 2021 There is a strong need for increased awareness, better prevention, detection, and treatment of Alzheimer’s disease with well over 5 million Americans currently suffering from this debilitating brain-wasting disease, and this number is projected to triple over the next few decades Research has found a link between Alzheimer’s disease and elevated levels of homocysteine. A recent study from Temple University has revealed another important connection between specific vitamin deficiencies and high homocysteine. Elevated homocysteine can increase the risk of dementia up to tenfold, and the list of ways this can affect the brain is long and damaging. This can include but is not limited to the formation of plaque in blood vessels that supply blood to the brain, development of chronic inflammation in the brain, and shrinkage of areas in the brain associated with memory. Additionally, excess homocysteine promotes the neurofibrillary tau tangles and harmful beta-amyloid plaques that are associated with AD, and it can interfere with the DNA repair process needed for brain cell maintenance. The harmful effects of elevated levels of homocysteine can all take a toll on brain function. For example, a study published in the Annals of Neuroscience found that elevated levels of homocysteine are associated with a 4.2-10.5 fold increased risk for vascular dementia, and the higher homocysteine rises the more damage it can cause. The study reported elevations in homocysteine were found to correspond closely to the degrees of cognitive impairment experienced by the participants. A report published in the Journal of Alzheimer’s Disease classified elevated homocysteine as a risk factor for Alzheimer’s disease, dementia, and cognitive decline. The researchers noted that the risk from elevated homocysteine was modifiable, meaning that reducing these levels could help to reduce the risk of brain damage. The recent study published in the journal Molecular Psychiatry describes the dangers of B-complex vitamin shortfalls in relation to homocysteine which is produced in the body in response to the breakdown of proteins and is normally detoxified by B-complex vitamins. Mice were deprived of vitamins B6, B9, and B12 for eight months, the animals were found to display elevated levels of homocysteine and 50% more tau tangles in the brain. The increased levels also caused increased levels of the pro-inflammatory chemical 5-LOX. The animals also displayed considerable difficulty with learning and remembering a water maze compared to the control group. The brain is not the only thing affected by high levels of homocysteine, this condition can also cause harm to the cardiovascular system including but not limited to damaging the lining of blood vessels, promoting deposits of plaque in the arteries that can cause a clog and increases the risk of heart attack or stroke. Research has shown that high levels of homocysteine is linked to a 42% increase in the risk of constricted carotid arteries which is a major risk factor for strokes. Elevated levels of homocysteine and poor arterial function can combine to interfere with the ability of the body to counter dangerous clotting inside of the arteries as well as with the ability of the heart to adapt to a blocked vessel by creating a new pathway. Elevated levels of homocysteine are dangerous to those with existing cardiovascular disease. A study involving over 3,000 participants with chronic heart disease found that elevated levels were associated with a 2.5 fold increased risk for coronary events. The researchers discovered a formula for measuring the risk, and suggested that every additional 5 micromoles per liter of homocysteine results in a 25% risk increase. As a product of less efficient detoxification functions levels of homocysteine tends to increase with aging. Genetics, stress, and the use of prescription drugs can also affect homocysteine levels. Experts suggest that a shortage in vitamins B2, B6, B9, and B12 that normally detoxify the amino acid are often the reason behind increasing levels of homocysteine. If you are concerned about your levels of homocysteine, or vitamin levels consult with your physician or certified medical professionals who may be able to address your concerns with a simple blood test. If you have reached or are approaching elderhood, with degenerative chronic conditions such as Alzheimer’s disease and heart disease on the rise it may be better to err on the side of caution and get checked rather than guess. Experts suggest that B complex vitamins are involved in breaking down homocysteine in the blood. These vitamins can be supplemented, but it is always best to obtain them via natural sources such as is found in eating a diet that is rich in fruits, vegetables, and whole grains. For example, vitamin B9 can be obtained in leafy greens and lentils; and B6 can be obtained in potatoes, chickpeas, and bananas; while B12 can be obtained in dairy products and organ meats.
 
For breakthroughs in slowing aging, scientists must look beyond biology University of Southern California, February 22, 2021 A trio of recent studies highlight the need to incorporate behavioral and social science alongside the study of biological mechanisms in order to slow aging. The three papers, published in concert in Ageing Research Reviews, emphasized how behavioral and social factors are intrinsic to aging. This means they are causal drivers of biological aging. In fact, the influence of behavioral and social factors on how fast people age are large and meaningful. However, geroscience--the study of how to slow biological aging to extend healthspan and longevity--has traditionally not incorporated behavioral or social science research. These papers are by three pioneers in aging research and members of the National Academy of Medicine who study different aspects of the intersection of biology and social factors in shaping healthy aging through the lifespan. Improving translation of aging research from mice to humans Exciting biological discoveries about rate of aging in non-human species are sometimes not applicable or lost when we apply them to humans. Including behavioral and social research can support translation of geroscience findings from animal models to benefit humans, said Terrie Moffitt, the Nannerl O. Keohane University Professor of Psychology and Neuroscience at Duke University. "The move from slowing fundamental processes of aging in laboratory animals to slowing aging in humans will not be as simple as prescribing a pill and watching it work," Moffitt said. "Compared to aging in laboratory animals, human aging has many behavioral/social in addition to cellular origins and influences. These influences include potential intervention targets that are uniquely human, and therefore are not easily investigated in animal research." Several of these human factors have big impacts on health and mortality: stress and early life adversity, psychiatric history, personality traits, intelligence, loneliness and social connection, and purpose in life are connected to a variety of late-life health outcomes, she explained. These important factors need to be taken into account to get a meaningful prediction of human biological aging. "Geroscience can be augmented through collaboration with behavioral and social science to accomplish translation from animal models to humans, and improve the design of clinical trials of anti-aging therapies," Moffitt said. "It's vital that geroscience advances be delivered to everyone, not just the well-to-do, because individuals who experience low education, low incomes, adverse early-life experiences, and prejudice are the people who age fastest and die youngest." Social factors associated with poor aging outcomes "Social hallmarks of aging" can be strongly predictive of age-related health outcomes - in many cases, even more so than biological factors, said USC University Professor and AARP Chair in Gerontology Eileen Crimmins. While the aging field commonly discusses the biological hallmarks of aging, we don't tend to include the social and behavioral factors that lead to premature aging. Crimmins has called the main five factors below "the Social Hallmarks of aging" and poses that these should not be ignored in any sample of humans and the concepts should be incorporated where possible into non-human studies. Crimmins examined data that was collected in 2016 from the Health and Retirement Study, a large, nationally representative study of Americans over the age of 56 that incorporates both surveys regarding social factors and biological measurements, including a blood sample for genetic analysis. For the study, she focused the five social hallmarks for poor health outcomes: low lifetime socioeconomic status, including lower levels of education adversity in childhood and adulthood, including trauma and other hardships being a member of a minority group adverse health behaviors, including smoking, obesity and problem drinking adverse psychological states, such as depression, negative psychological outlook and chronic stress The presence of these five factors were strongly associated with older adults having difficulty with activities of daily living, experiencing problems with cognition, and multimorbidity (having five or more diseases). Even when controlling for biological measurements - including blood pressure, genetic risk factors, mitochondrial DNA copy number and more - the social differences, as well as demographic factors such as age and gender, explained most of the differences in aging outcomes between study subjects, she said. However, biological and social factors aren't completely independent from one another, Crimmins added, which is why she advocates for further incorporation of social and behavioral factors in aging biology research. "Variability in human aging is strongly related to the social determinants of aging; and it remains so when extensive biology is introduced as mediating factors. This means that the social variability in the aging process is only partly explained by the biological measures researchers currently use," she said. "Our hypothesis is that if we could fully capture the basic biological mechanisms of aging, they would even more strongly explain the social variability in the process of aging, as social factors need to 'get under the skin' through biology." Understanding stress and stress resilience Elissa Epel, professor and vice chair in the Department of Psychiatry and Behavioral Sciences at UC San Francisco, detailed how research on stress and resilience needs to incorporate psychosocial factors in order to understand how different kinds of stress affect aging. Not all types of stress are equal and in fact some are salutary. The social hallmarks of aging can shape the rate of aging in part through toxic stress responses, she said. While acute responses to minor or moderate stressors, including infection or injury, is critical to survival, chronic exposure to high amounts of stress--including long-term psychological stressors such as abuse--can prove toxic and result in poor health outcomes. "Brief, intermittent, low-dose stressors can lead to positive biological responses, improving resistance to damage, which is called hormesis," Epel explained. For example, physiological hormetic stressors include short term exposure to cold, heat, exercise, or hypoxia. Hormetic stress turns on mechanisms of cell repair and rejuvenation. "In contrast, a high dose of a chronic exposure can override these mechanisms, resulting in damage or death," she added. Thus, toxic stress can accelerate biological aging processes, whereas hormetic stress can slow aging. However, the types, timing, and frequency of hormetic stress need to be better delineated in order to be useful to human aging research and interventions, Epel said. "Stress resilience, an umbrella term including hormetic stress, can be measured across cellular, physiological, and psychosocial functioning," she said. "Developing a deeper understanding of stress resilience will lead to more targeted innovative interventions." Stress resilience can also include social interventions that protect from the malleable social hallmarks of aging, including safe neighborhoods to reduce trauma and violence, and social support programs to combat loneliness and depression. Geroscience is now more important than ever, both to our aging global demography but also to the health challenges we face going forward, and stress resilience is an especially important topic at the moment, Epel added. "In our new era, we have dramatically increasing temperature extremes, wildfires and small particle pollution, and new zoonotic viruses to contend with intermittently," she said. "Reducing social disparities, improving stress resilience and bolstering immune function have become critical public health goals." In sum, the three papers together point to a promising decade ahead for aging research. Humans, as complex social mammals, age together in response to social conditions and behavioral factors that are partly malleable. Epel explains "As we discover and test biological processes of aging that we can manipulate, we can do this in tandem with capitalizing on the natural levers of healthy aging that are powerful, interactive, and cannot be ignored. In this way, the fountain of youth becomes more attainable."
 
Up to 10 portions of fruit and vegetables a day may prevent 7.8 million premature deaths Imperial College London, February 22, 2021 A fruit and vegetable intake above five-a-day shows major benefit in reducing the chance of heart attack, stroke, cancer and early death. This is the finding of new research, led by scientists from Imperial College London, which analysed 95 studies on fruit and vegetable intake. The team found that although even the recommended five portions of fruit and vegetables a day reduced disease risk, the greatest benefit came from eating 800g a day (roughly equivalent to ten portions - one portion of fruit or vegetables if defined as 80g). The study, which was a meta-analysis of all available research in populations worldwide, included up to 2 million people, and assessed up to 43,000 cases of heart disease, 47,000 cases of stroke, 81,000 cases of cardiovascular disease, 112,000 cancer cases and 94,000 deaths. In the research, which is published in the International Journal of Epidemiology, the team estimate approximately 7.8 million premature deaths worldwide could be potentially prevented every year if people ate 10 portions, or 800 g, of fruit and vegetables a day. The team also analysed which types of fruit and vegetables provided the greatest protection against disease. Dr Dagfinn Aune, lead author of the research from the School of Public Health at Imperial explained: "We wanted to investigate how much fruit and vegetables you need to eat to gain the maximum protection against disease, and premature death. Our results suggest that although five portions of fruit and vegetables is good, ten a day is even better." The results revealed that even a daily intake of 200g was associated with a 16 per cent reduced risk of heart disease, an 18 per cent reduced risk of stroke, and a 13 per cent reduced risk of cardiovascular disease. This amount, which is equivalent to two and a half portions, was also associated with 4 per cent reduced risk in cancer risk, and 15 per cent reduction in the risk of premature death. Further benefits were observed with higher intakes. Eating up to 800g fruit and vegetables a day - or 10 portions - was associated with a 24 per cent reduced risk of heart disease, a 33 per cent reduced risk of stroke, a 28 per cent reduced risk of cardiovascular disease, a 13 per cent reduced risk of total cancer, and a 31 per cent reduction in dying prematurely. This risk was calculated in comparison to not eating any fruit and vegetables. The team were not able to investigate intakes greater than 800 g a day, as this was the high end of the range across studies. An 80g portion of fruit and vegetables equals approximately one small banana, apple, pear or large mandarin. Three heaped tablespoons of cooked vegetables such as spinach, peas, broccoli or cauliflower count as a portion. The researchers also examined the types of fruit and vegetables that may reduce the risk of specific diseases. They found the following fruits and vegetables may help prevent heart disease, stroke, cardiovascular disease, and early death: apples and pears, citrus fruits, salads and green leafy vegetables such as spinach, lettuce and chicory, and cruciferous vegetables such as broccoli, cabbage and cauliflower. They also found the following may reduce cancer risk: green vegetables, such as spinach or green beans, yellow vegetables, such as peppers and carrots, and cruciferous vegetables. Similar associations were observed for raw and cooked vegetables in relation to early death, however, additional studies are needed on specific types of fruits and vegetables and preparation methods. The team say the number of studies was more limited for these analyses, and the possibility that other specific fruits and vegetables may also reduce risk cannot be excluded. Dr Aune said that several potential mechanisms could explain why fruit and vegetables have such profound health benefits: "Fruit and vegetables have been shown to reduce cholesterol levels, blood pressure, and to boost the health of our blood vessels and immune system. This may be due to the complex network of nutrients they hold. For instance they contain many antioxidants, which may reduce DNA damage, and lead to a reduction in cancer risk." He added that compounds called glucosinolates in cruciferous vegetables, such as broccoli, activate enzymes that may help prevent cancer. Furthermore fruit and vegetables may also have a beneficial effect on the naturally-occurring bacteria in our gut. The vast array of beneficial compounds cannot be easily replicated in a pill, he said: "Most likely it is the whole package of beneficial nutrients you obtain by eating fruits and vegetables that is crucial is health. This is why it is important to eat whole plant foods to get the benefit, instead of taking antioxidant or vitamin supplements (which have not been shown to reduce disease risk)." In the analysis, the team took into account other factors, such as a person's weight, smoking, physical activity levels, and overall diet, but still found that fruit and vegetables were beneficial. Dr Aune added: "We need further research into the effects of specific types of fruits and vegetables and preparation methods of fruit and vegetables. We also need more research on the relationship between fruit and vegetable intake with causes of death other than cancer and cardiovascular disease. However, it is clear from this work that a high intake of fruit and vegetables hold tremendous healthbenefits, and we should try to increase their intake in our diet."
 
Alpha-lipoic acid an effective antioxidant for healthy adult dogs Hills Pet Nutrition Research, February 19, 2021 According to news reporting originating from the Hill’s Pet Nutrition research stated, “This study was designed to determine the effect of alpha-lipoic acid on the glutathione status in healthy adult dogs.” Our news reporters obtained a quote from the research from Hill’s Pet Nutrition: “Following a 15 month baseline period during which dogs were fed a food containing no alpha-lipoic acid, dogs were randomly allocated into four groups. Groups were then fed a nutritionally complete and balanced food with either 0, 75, 150 or 300 ppm of alpha-lipoic acid added for 6 months. Evaluations included physical examination, body weight, food intake, hematology, serum biochemistry profile and measurements of glutathione in plasma and erythrocyte lysates. Throughout, blood parameters remained within reference ranges, dogs were healthy and body weight did not change significantly. A significant increase of 0.05 ng/mL of total glutathione in red blood cell (RBC) lysate for each 1 mg/kg bodyweight/day increase in a-LA intake was observed. In addition, a significant increase was observed for GSH, GSSG and total glutathione in RBC lysate at Month 6.” According to the news editors, the research concluded: “We conclude that alpha-lipoic acid, as part of a complete and balanced food, was associated with increasing glutathione activity in healthy adult dogs.”

Study: Ashwagandha extract can be used to improve sleep quality and relieve stress Patil University School of Medicine (India), February 19, 2021 Ashwagandha, also known as Withania somnifera or Indian ginseng, is a medicinal herb native to India and North Africa. It has been used for over 3,000 years to relieve stress, as well as to increase energy levels and improve concentration. A recent study published in the journal Cureus suggests it may hold the key to treating insomnia. A team of researchers from Patil University School of Medicine, Vedantaa Institute of Medical Sciences and Prakruti Hospital conducted a randomized, double-blind, placebo-controlled study to determine the effects of ashwagandha root extract in patients with insomnia and anxiety. A total of 60 participants were randomly divided into two groups: 40 were placed in the test group and given a capsule containing 300 mg of high-concentration ashwagandha root extract, while the remaining 20 formed the placebo group. Those in the placebo group received capsules containing starch twice a day over a period of ten weeks. The researchers used Sleep Actigraphy to assess sleep onset latency (SOL), total sleep time (TST), sleep efficiency (SE) and wake after sleep onset (WASO). Other factors that the research team looked at were total time in bed, mental alertness on rising, sleep quality, Pittsburgh Sleep Quality Index (PSQI) and the Hamilton Anxiety Rating Scale. According to the researchers, SOL, SE and sleep quality were visibly improved after ashwagandha treatment, along with other sleep parameters. (Related: Ashwagandha: Discover the health benefits of this popular ancient adaptogen.) Their findings suggest that ashwagandha can be used to improve sleep in patients with insomnia and anxiety, although further large-scale studies are needed. Omega-3 supplements may reduce muscle soreness after exercise, study finds University of Westminster (UK), February 18, 2021 Researchers at the University of Westminster have found that taking omega-3 supplements may help to reduce muscle soreness after exercise. The findings may be important for people who avoid exercise because of the soreness associated with it. Omega-3 fatty acids are polyunsaturated fatty acids that play important roles in our bodies and may provide a number of health benefits. These are essential fats as our bodies cannot produce them and we must get them from our diet, primarily from oily fish. They have anti-inflammatory functions, can help maintain a healthy heart, reduce the risk of heart disease and may have incredible effects on brain and mental health. Previous studies have looked at the effect of omega-3 fish oils on muscle damage recovery and muscle inflammation following exercise. Whilst evidence is mixed, it has been shown that sustained omega-3 intake in your diet may lead to small gains in recovery for athletes following intense exercise and possibly small gains in exercise performance too. In this study, the researchers gave people omega-3 capsules three times a day for four weeks, or a matching placebo, to build up their levels. They then took part in a very intense exercise program aimed at causing severe muscle pain and physiologically safe muscle damage. The researchers then measured blood levels of inflammation and muscle damage markers, physical pain and the ability of the participants to do forceful muscle contractions every day for the next three days. They found a lower inflammatory response and decreased muscle damage after exercise in the fish oil group. However, the omega-3 did not seem to change the amount of force reduction in future muscle contractions, suggesting that omega-3 supplementation had limited impact on muscle function, recovery and subsequent performance, but it did reduce the pain participants experienced. Talking about the study, Ph.D. researcher and lead author Yvoni Kyriakidou, from the University of Westminster's School of Life Sciences, said: "Whilst the omega-3 supplementation didn't seem to enhance performance, it did reduce the pain participants experienced which we suggest is useful in itself as people don't like exercise because it hurts. If it doesn't hurt as much, maybe more people will keep doing it?" Higher intake of carotenoid beta cryptoxanthin associated with lower risk of osteoporosis Seoul National University (South Korea), February 12, 2021 According to news reporting out of Seoul, South Korea, research stated, “Many studies have analyzed the effects of * * b* * -cryptoxanthin (BCX) on osteoporosis and bone health. This systematic review and meta-analysis aimed at providing quantitative evidence for the effects of BCX on osteoporosis.” The news journalists obtained a quote from the research from Seoul National University: “Publications were selected and retrieved from three databases and carefully screened to evaluate their eligibility. Data from the final 15 eligible studies were extracted and uniformly summarized. Among the 15 studies, seven including 100,496 individuals provided information for the meta-analysis. A random effects model was applied to integrate the odds ratio (OR) to compare the risk of osteoporosis and osteoporosis-related complications between the groups with high and low intake of BCX. A high intake of BCX was significantly correlated with a reduced risk of osteoporosis (OR = 0.79, 95% confidence interval (CI) 0.70-0.90, * * p* * = 0.0002). The results remained significant when patients were stratified into male and female subgroups as well as Western and Asian cohorts. A high intake of BCX was also negatively associated with the incidence of hip fracture (OR = 0.71, 95% CI 0.54-0.94, * * p* * = 0.02).” According to the news reporters, the research concluded: “The results indicate that BCX intake potentially reduces the risk of osteoporosis and hip fracture. Further longitudinal studies are needed to validate the causality of current findings.” Being male, having overweight and depression can influence aging Vrije University (Netherlands) and Virginia Commonwealth University, February 15, 2021 Scientists are using biology to more accurately measure how quickly humans age. One factor is the length of an individual’s telomeres, stretches of DNA and proteins at the ends of our chromosomes that shorten as we age. An epigenetic clock, meanwhile, looks at the changes in gene function that do not make alterations to the genetic code, or genome. Another aging clock is based on transcriptomes, a collection of all the gene readouts in a cell. Scientists also measure age with metabolomics, the study of the chemical processes that involve metabolites, small molecules produced by and during metabolic processes. In addition, scientists use what they call a proteomic clock, which measures levels of proteins in the blood. For a new study, now published in the journal eLife, researchersset out to learn whether a composite biological clock outperforms individual biological clocks in predicting health. “To develop a better understanding of the mechanisms underlying biological aging, we wanted to examine how indicators of biological aging relate to each other, how they link to determinants of physical and mental health, and whether a combined biological clock, made up of all age indicators, is a better predictor of health,” says co-lead author Dr. Rick Jansen, an assistant professor in the department of psychiatry at Amsterdam UMC, in the Netherlands. Examining biological aging indicators The researchers used blood samples from 2,981 individuals aged 18–65 years who took part in the Netherlands Study of Depression and Anxiety. Of the participants, 74% had a diagnosis of a depressive disorder, an anxiety disorder, or both, while 26% were healthy control participants. The participants were recruited from medical facilities and the general population between September 2004 and February 2007. The team used computer modeling to examine whether five measures of biological aging — telomere length and the epigenetic, transcriptomic, proteomic, and metabolomic clocks — were interrelated and associated with mental and physical health. The researchers then took the five indicators and incorporated them into an analysis that also included sex, lifestyle factors, physical ability, and known health conditions. What makes people age faster? The scientists found that being male was associated with more advanced biological aging according to four of the five biological clock measurements. This is consistent with the understanding that in most places, women outlive men. Other factors associated with more advanced biological aging according to at least four of the five measures were: having a high body mass index, smoking, and having metabolic syndrome. The researchers also discovered that depression is linked to more advanced biological aging. In addition, they noted associations between medication use and this aging. However, they could not determine whether this was due to the medication itself or the underlying physical or mental illness requiring treatment. Meanwhile, the study allowed the researchers to infer that some biological clocks show overlap, but most seem to be tracking different aspects of the aging process. They write: “This provides further support for the hypothesis that not one biological clock sufficiently captures the biological aging process and that not all clocks are under the control of one unitary aging process.” Vitamin B3 prevents glaucoma in laboratory mice Jackson Laboratory, February 16, 2021 In mice genetically predisposed to glaucoma, vitamin B3 added to drinking water is effective at preventing the disease, a research team led by Jackson Laboratory Professor and Howard Hughes Medical Investigator Simon W.M. John reports in the journal Science. The vitamin administration was surprisingly effective, eliminating the vast majority of age-related molecular changes and providing a remarkably robust protection against glaucoma. It offers promise for developing inexpensive and safe treatments for glaucoma patients. Glaucoma is one of the most common neurodegenerative diseases, affecting an estimated 80 million people worldwide. In most glaucoma patients, harmfully high pressure inside the eye or intraocular pressure leads to the progressive dysfunction and loss of retinal ganglion cells. Retinal ganglion cells are the neuronal cells that connect the eye to the brain via the optic nerve. Increasing age is a key risk factor for glaucoma, contributing to both harmful elevation of intraocular pressure and increased neuronal vulnerability to pressure-induced damage. "We wanted to identify key age-related susceptibility factors that change with age in the eye," John says, "and that therefore increase vulnerability to disease and in particular neuronal disease." By understanding general age-related mechanism, there is the potential to develop new interventions to generally protect from common age-related disease processes in many people. Conducting a variety of genomic, metabolic, neurobiological and other tests in mice susceptible to inherited glaucoma, compared to control mice, the researchers discovered that NAD, a molecule vital to energy metabolism in neurons and other cells, declines with age. "There's an analogy with an old motorbike," John says. "It runs just fine, but little things get less reliable with age. One day you stress it: you drive it up a steep hill or you go on really long journey and you get in trouble. It's less reliable than a new bike and it's going to fail with a higher frequency than that new bike." The decrease in NAD levels reduces the reliability of neurons' energy metabolism, especially under stress such as increased intraocular pressure. "Like taking that big hill on your old bike, some things are going to fail more often," John says. "The amount of failure will increase over time, resulting in more damage and disease progression." In essence, the treatments of vitamin B3 (nicotinamide, an amide form of vitamin B3, also called niacinamide) boosted the metabolic reliability of aging retinal ganglion cells, keeping them healthier for longer. "Because these cells are still healthy, and still metabolically robust," says JAX Postdoctoral Associate Pete Williams, first author of the study, "even when high intraocular pressure turns on, they better resist damaging processes." The researchers also found that a single gene-therapy application of Nmnat1 (the gene for an enzyme that makes NAD from nicotinamide) prevented glaucoma from developing in this mouse model. "It can be a problem for patients, especially the elderly, to take their drugs every day and in the correct dose," Williams says. "So gene therapy could be a one-shot, protective treatment." He notes that gene therapies, through injections into the eye, have been approved for a handful of very rare, human genetic eye disorders, and their demonstration of an important age-dependent factor may enable gene therapy for more common eye disease. John says that the team is pursuing clinical partnerships to begin the process of testing the effectiveness of vitamin B3 treatment in glaucoma patients. They are also exploring potential applications for the treatment in other diseases involving neurodegeneration. Even short periods of being sedentary is bad for your heart, caution researchers University of Liverpool, February 18, 2021 Researchers from the University of Liverpool in the U.K. found that short periods of being sedentary can worsen cardiometabolic health. In a study published in the journal Diabetologia, the researchers revealed that reducing physical activity for at least two weeks can lead to a rise in blood sugar levels, disrupt cholesterol levels and impair cardiorespiratory fitness. Increased sedentary behavior worsens cardiometabolic health It’s no secret that physical inactivity is bad for health. Research shows that physical inactivity and sedentary behavior are major risk factors for obesity, insulin resistance and Type 2 diabetes. But little is known about the consequences of short-term physical inactivity. For their study, the researchers examined the metabolic consequences of short-term increased sedentary behavior in 45 healthy adults with a mean age of 36 years. All of the participants have a mean daily step count of more than 10,000 steps and were asked to reduce their daily step count to around 1,500 steps for two weeks. The researchers measured the participants’ cardiorespiratory fitness, body composition and multi-organ insulin sensitivity at baseline, after the two-week step reduction and two weeks after the participants resumed their normal physical activity. The team found that the participants developed “metabolic derangements” after two weeks of increased sedentary behavior. Their blood sugar and bad cholesterol levels rose, and their insulin sensitivity declined. In addition, the participants lost a little muscle mass in their legs and gained fat around their liver and abdomen. (Related: Twice as many deaths are caused by physical inactivity compared to obesity, stunning study finds.) Fortunately, these changes were reversed after the participants resumed their normal routine. For some reason, however, some participants failed to return to quite the same level of exercise they had engaged in prior to the study. These participants now completed fewer minutes of vigorous activity each week and exhibited slight but lasting symptoms of insulin resistance. While this lasting effect might be due to the participants’ lower levels of vigorous activity, the researchers are also open to the possibility that this stemmed from genetic factors.

Gut microbiome implicated in healthy aging and longevity
Data from over 9,000 people reveal a distinct gut microbiome signature that is associated with healthy aging and survival in the latest decades of life
Institute for Systems Biology (Seattle), February 18, 2021
The gut microbiome is an integral component of the body, but its importance in the human aging process is unclear. ISB researchers and their collaborators have identified distinct signatures in the gut microbiome that are associated with either healthy or unhealthy aging trajectories, which in turn predict survival in a population of older individuals. The work is set to be published in the journal Nature Metabolism.
The research team analyzed gut microbiome, phenotypic and clinical data from over 9,000 people - between the ages of 18 and 101 years old - across three independent cohorts. The team focused, in particular, on longitudinal data from a cohort of over 900 community-dwelling older individuals (78-98 years old), allowing them to track health and survival outcomes. 
The data showed that gut microbiomes became increasingly unique (i.e. increasingly divergent from others) as individuals aged, starting in mid-to-late adulthood, which corresponded with a steady decline in the abundance of core bacterial genera (e.g. Bacteroides) that tend to be shared across humans.
Strikingly, while microbiomes became increasingly unique to each individual in healthy aging, the metabolic functions the microbiomes were carrying out shared common traits. This gut uniqueness signature was highly correlated with several microbially-derived metabolites in blood plasma, including one - tryptophan-derived indole - that has previously been shown to extend lifespan in mice. Blood levels of another metabolite - phenylacetylglutamine - showed the strongest association with uniqueness, and prior work has shown that this metabolite is indeed highly elevated in the blood of centenarians.
"This uniqueness signature can predict patient survival in the latest decades of life," said ISB Research Scientist Dr. Tomasz Wilmanski, who led the study. Healthy individuals around 80 years of age showed continued microbial drift toward a unique compositional state, but this drift was absent in less healthy individuals. 
"Interestingly, this uniqueness pattern appears to start in mid-life - 40-50 years old - and is associated with a clear blood metabolomic signature, suggesting that these microbiome changes may not simply be diagnostic of healthy aging, but that they may also contribute directly to health as we age," Wilmanski said. For example, indoles are known to reduce inflammation in the gut, and chronic inflammation is thought to be a major driver in the progression of aging-related morbidities.
"Prior results in microbiome-aging research appear inconsistent, with some reports showing a decline in core gut genera in centenarian populations, while others show relative stability of the microbiome up until the onset of aging-related declines in health," said microbiome specialist Dr. Sean Gibbons, co-corresponding author of the paper. "Our work, which is the first to incorporate a detailed analysis of health and survival, may resolve these inconsistencies. Specifically, we show two distinct aging trajectories: 1) a decline in core microbes and an accompanying rise in uniqueness in healthier individuals, consistent with prior results in community-dwelling centenarians, and 2) the maintenance of core microbes in less healthy individuals."
This analysis highlights the fact that the adult gut microbiome continues to develop with advanced age in healthy individuals, but not in unhealthy ones, and that microbiome compositions associated with health in early-to-mid adulthood may not be compatible with health in late adulthood.
"This is exciting work that we think will have major clinical implications for monitoring and modifying gut microbiome health throughout a person's life," said ISB Professor Dr. Nathan Price, co-corresponding author of the paper. 
 
 
Rosmarinic acid suppresses cognitive decline in Alzheimer disease mouse model
University of Tokyo (Japan), February 15, 2021
 
According to news originating from the University of Tokyo , research stated, “Rosmarinic acid (RA), a polyphenol found in Lamiaceae herbs, is a candidate of preventive ingredients against Alzheimer’s disease (AD) as it potently suppresses the aggregation of amyloid b (Ab); however, the effect of RA on tau phosphorylation and cognitive dysfunction remains unclear.”
Financial supporters for this research include Japan Society for the Promotion of Science; Japan Agency for Medical Research and Development; Cross-Ministerial Strategic Innovation Promotion Program.
The news editors obtained a quote from the research from University of Tokyo: “The present study revealed that RA intake inhibited the pathological hallmarks of AD, including Ab and phosphorylated tau accumulation, and improved cognitive function in the 3 x Tg-AD mouse model. Additionally, RA intake suppressed hippocampal inflammation and led to the downregulation of the JNK signaling pathway that induces tau phosphorylation. Feeding with RA exerted an anti-inflammatory effect not only in the central nervous system but also in the periphery.”
According to the news editors, the research concluded: “Downregulation of the JNK signaling pathway in hippocampus may be a potential mechanism underlying the inhibition of progression of pathology and cognitive deficit by RA feeding.”
 
 
 
Excess fatty tissue accumulated in the neck increases the chances of suffering heart problems, according to a new study
University of Granada (Spain), February 15, 2021
Researchers from the University of Granada warn that an accumulation of fatty tissue in the neck (both the double chin and the deeper deposits, located between muscles and around the cervical vertebrae) is a predictor of central and overall adiposity, cardiometabolic risk, and a pro-inflammatory profile in sedentary young adults.
Traditionally, the accumulation of visceral adipose tissue has been considered one of the factors most strongly related to cardiometabolic risk and chronic (low-grade) inflammation in humans. However, this well-established association has led researchers to neglect, to some degree, the study of other fatty deposits and their clinical/biological relevance.
"Curiously, several studies have demonstrated that the accumulation of fat in the neck (both superficial deposits such as the double chin or jowls and the deeper deposits, located between the muscles and around the cervical vertebrae) increases in direct proportion to the weight or adiposity of the individual and that it follows specific accumulation patterns, according to gender," explains María José Arias Téllez, a researcher at the UGR and one of the main authors of this work. 
In fact, a greater accumulation of fat in certain neck tissue compartments, particularly the deeper ones, is linked to a greater likelihood of cardiometabolic risk. Arias Téllez says, "However, the evidence accumulated to date has been based on experiments performed on patients with benign/malignant tumors or other chronic conditions, and it remains to be seen whether it can be generalized to relatively healthy adults."
The study carried out at the UGR is part of the ACTIBATE project (Activating Brown Adipose Tissue through Exercise—seeprofith.ugr.es/actibate). The research was led by Jonatan Ruiz Ruiz and its results have been published in the International Journal of Obesity.
The study shows that the accumulation of fat in the neck—measured with computed tomography scanning—as well as its distribution in different compartments, is associated with greater overall and central adiposity, greater cardiometabolic risk, and a greater inflammatory status among healthy young adults, regardless of the amount of total and visceral fat. In addition, among the most relevant findings, the researchers observed that this accumulation of fat in the neck was as powerful a factor (in terms of direction and magnitude) as the accumulation of visceral fat in the prediction of cardiometabolic risk and inflammatory status, especially in men.
"Therefore, these results underline the need for further research in this new direction, to better understand the effect of fat accumulation in the upper part of the trunk (including the neck) and its clinical repercussions, especially in cardiometabolic riskand inflammation," explains Francisco Miguel Acosta Manzano, one of the main authors of the research.
"We still have much work to do. We need to investigate the adipose tissue of the neck in greater depth, to understand its pathogenic role in obesity and associated comorbidities, as well as its biological importance. Furthermore, we only have scant knowledge about the morphological or molecular characteristics of the adipocytes in these deposits, and here basic studies are required. As we increase our knowledge of this deposit, we can also determine whether specific interventions (for example, physical exercise and/or restricted calorie intake) could help reduce the accumulation of fat in the neck (as well as total fat) and implement them clinically," explain Arias Téllez and Francisco Miguel Acosta Manzano, both Ph.D.s students on the Biomedicine program of the UGR's International School for Postgraduate Studies 
 
Effects of saffron extract supplementation on mood, well-being and response to a psychosocial stressor in healthy adults
Northumbria University (UK), February 16, 2021
According to news reporting originating from Newcastle upon Tyne, United Kingdom, research stated, “Anxiety, stress, and low mood are closely related and may contribute to depressive symptoms. Among non-pharmacological solutions to improve subclinical mood symptoms and resilience to stress, natural products such as saffron-identified as promising following preliminary beneficial effects in major depressive disorder-represent a relevant strategy.”
Our news reporters obtained a quote from the research from Northumbria University: “This study aimed to assess the efficacy of 8 weeks’ supplementation with 30 mg standardized saffron extract on emotional well-being in healthy adults with subclinical feelings of low mood and anxiety and/or stress and evaluate the acute effect of saffron in response to a lab-based psychosocial stressor. The study adopted a double-blind, randomized, parallel groups design in which 56 healthy male and female individuals (18-54 years) received either a saffron extract or a placebo for 8 weeks. Chronic effects of saffron on subjective anxiety, stress, and depressive feelings were assessed using a questionnaire battery [including Profile of Mood State-2, (POMS)] and acute effects in response to a lab-based psychosocial stressor were measured through psychological and physiological parameters. Urinary crocetin levels were quantified. Participants who received the saffron extract reported reduced depression scores and improved social relationships at the end of the study. Urinary crocetin levels increased significantly with saffron supplementation and were correlated with change in depression scores. The typical stress-induced decrease in heart rate variability (HRV) during exposure to the stressor was attenuated following acute saffron intake.”
According to the news editors, the research concluded: “Saffron extract appears to improve subclinical depressive symptoms in healthy individuals and may contribute to increased resilience against the development of stress-related psychiatric disorders. Clinical trials number: NCT03639831.”
 
 
The science of siestas: New research reveals the genetic basis for daytime napping
Massachusetts General Hospital and University of Murcia (Spain), February 13, 2021
 
How often a person takes daytime naps, if at all, is partly regulated by their genes, according to new research led by investigators at Massachusetts General Hospital (MGH) and published in Nature Communications. In this study, the largest of its kind ever conducted, the MGH team collaborated with colleagues at the University of Murcia in Spain and several other institutions to identify dozens of gene regions that govern the tendency to take naps during the day. They also uncovered preliminary evidence linking napping habits to cardiometabolic health
Napping is somewhat controversial,” says Hassan Saeed Dashti, Ph.D., RD, of the MGH Center for Genomic Medicine, co-lead author of the report with Iyas Daghlas, a medical student at Harvard Medical School (HMS). Dashti notes that some countries where daytime naps have long been part of the culture (such as Spain) now discourage the habit. Meanwhile, some companies in the United States now promote napping as a way to boost productivity. “It was important to try to disentangle the biological pathways that contribute to why we nap,” says Dashti. 
 
Previously, co-senior author Richa Saxena, Ph.D., principal investigator at the Saxena Lab at MGH, and her colleagues used massive databases of genetic and lifestyle information to study other aspects of sleep. Notably, the team has identified genes associated with sleep duration, insomnia, and the tendency to be an early riser or “night owl.” To gain a better understanding of the genetics of napping, Saxena’s team and co-senior author Marta Garaulet, Ph.D., of the Department of Physiology at the University of Murcia, performed a genome-wide association study (GWAS), which involves rapid scanning of complete sets of DNA, or genomes, of a large number of people. The goal of a GWAS is to identify genetic variations that are associated with a specific disease or, in this case, habit.
 
For this study, the MGH researchers and their colleagues used data from the UK Biobank, which includes genetic information from 452,633 people. All participants were asked whether they nap during the day “never/rarely,” “sometimes” or “usually.” The GWAS identified 123 regions in the human genome that are associated with daytime napping. A subset of participants wore activity monitors called accelerometers, which provide data about daytime sedentary behavior, which can be an indicator of napping. This objective data indicated that the self-reports about napping were accurate. “That gave an extra layer of confidence that what we found is real and not an artifact,” says Dashti.
 
Several other features of the study bolster its results. For example, the researchers independently replicated their findings in an analysis of the genomes of 541,333 people collected by 23andMe, the consumer genetic-testing company. Also, a significant number of the genes near or at regions identified by the GWAS are already known to play a role in sleep. One example is KSR2, a gene that the MGH team and collaborators had previously found plays a role in sleep regulation.
 
Digging deeper into the data, the team identified at least three potential mechanisms that promote napping:
Sleep propensity: Some people need more shut-eye than others.
Disrupted sleep: A daytime nap can help make up for poor quality slumber the night before.
Early morning awakening: People who rise early may “catch up” on sleep with a nap.
 
“This tells us that daytime napping is biologically driven and not just an environmental or behavioral choice,” says Dashti. Some of these subtypes were linked to cardiometabolic health concerns, such as large waist circumference and elevated blood pressure, though more research on those associations is needed. “Future work may help to develop personalized recommendations for siesta,” says Garaulet. 
Furthermore, several gene variants linked to napping were already associated with signaling by a neuropeptide called orexin, which plays a role in wakefulness. “This pathway is known to be involved in rare sleep disorders like narcolepsy, but our findings show that smaller perturbations in the pathway can explain why some people nap more than others,” says Daghlas.
 
One or more soda a day could decrease chances of getting pregnant
Boston University School of Public Health,  February 13, 2021
The amount of added sugar in the American diet has increased dramatically over the last 50 years. Much of that increase comes from higher intake of sugar-sweetened beverages, which constitute approximately one-third of the total added sugar consumption in the American diet. While consumption of these beverages has been linked to weight gain, type 2diabetes, early menstruation, and poor semen quality, few studies have directly investigated the relationship between sugary drinks and fertility.
Now, a new study led by Boston University School of Public Health (BUSPH) researchers has found that the intake of one or more sugar-sweetened beverages per day—by either partner—is associated with a decreased chance of getting pregnant.
The study was published in Epidemiology.
"We found positive associations between intake of sugar-sweetened beverages and lower fertility, which were consistent after controlling for many other factors, including obesity, caffeine intake, alcohol, smoking, and overall diet quality," says lead author Elizabeth Hatch, professor of epidemiology. "Couples planning a pregnancy might consider limiting their consumption of these beverages, especially because they are also related to other adverse health effects."
About 15 percent of couples in North America experience infertility. Identifying modifiable risk factors for infertility, including diet, could help couples conceive more quickly and reduce the psychological stress and financial hardship related to fertility treatments, which are associated with more than $5 billion in annual US healthcare costs.
Through the Pregnancy Study Online (PRESTO), an ongoing web-based prospective cohort study of North American couples, the researchers surveyed 3,828 women aged 21 to 45 living in the United States or Canada and 1,045 of their male partners. Participants completed a comprehensive baseline survey on medical history, lifestyle factors, and diet, including their intake of sugar-sweetened beverages. Female participants then completed a follow-up questionnaire every two months for up to 12 months or until pregnancy occurred.
Both female and male intake of sugar-sweetened beverages was associated with 20 percent reduced fecundability, the average monthly probability of conception. Females who consumed at least one soda per day had 25 percent lower fecundability; male consumption was associated with 33 percent lower fecundability. Intake of energy drinks was related to even larger reductions in fertility, although the results were based on small numbers of consumers. Little association was found between intake of fruit juices or diet sodas and fertility.
"Given the high levels of sugar-sweetened beverages consumed by reproductive-aged couples in North America, these findings could have important public healthimplications," the authors concluded.

Prevent memory loss with a powerful nutrient in cucumbers
Salk Institute for Biological Studies, February 16, 2021
The results of a recent study are offering new hope that avoiding memory loss related to aging as well as Alzheimer’s disease could be as simple as eating more cucumbers.
Many older adults resign themselves to memory loss as part of the aging process. However, a study out of the the Salk Institute for Biological Studies has shown that this doesn’t have to be the case. The health benefits of cucumbers are many, and one of them seems to be better memory and even the prevention of Alzheimer’s disease.
Researchers working with mice that normally developed the symptoms of Alzheimer’s (including memory loss) discovered that a daily dose of a flavonol called fisetin prevented these and other related impairments. This improvement occurred despite the continued formation of amyloid plaques, the brain proteins commonly blamed for Alzheimer’s.
A natural food cure for memory loss
The compound fisetin is found in numerous vegetables and fruits but is especially concentrated in strawberries and cucumbers. This flavonol is quite effective in stopping memory loss in mice and holds hope for humans as well.
In the past, the main approach to treating Alzheimer’s symptoms was to target amyloid plaques in the brain. The findings of this study call into question the assumption that these proteins are largely responsible for the effects of Alzheimer’s.
Even in animals with no signs of Alzheimer’s and otherwise normal functioning, fisetin has been shown to improve memory. However, its ability to prevent memory loss associated with Alzheimer’s disease could have profound implications for humans.
Cucumbers protect the brain from inflammation
Fisetin works by switching on a cellular pathway associated with the process of retrieving memories in the brain. Over a decade ago, other researchers discovered the compound fisetin assists in protecting the neurons of the brain from agingand its associated effects. It was found that this potent compound has both anti-inflammatory and antioxidant effects on brain cells.
The list of health benefits of cucumbers, strawberries and other fruits and vegetables containing fisetin now include brain and memory improvements. By extension, fisetin has properties that can be highly beneficial for those at risk for Alzheimer’s.
Other health benefits of cucumbers
In addition to improving memory and potentially protecting against Alzheimer’s, the cucumber fruit has a range of additional nutritional and health benefits. They are low in calories (a cup of cucumbers contains just 16 calories) and assist in hydration (they are comprised of 95 percent water). They also provide flavonoids, triterpenes and lignans which offer anti-inflammatory, antioxidant and cancer-preventing benefits.
The peel and seeds in cucumbers contain beta-carotene for eye health and are the most nutrient-dense portions of the fruit. Cucumber seeds contain calcium and the skin and seeds are also excellent sources of fiber. Other vitamins include potassium, vitamin C, magnesium and manganese.
 
 
Testosterone levels increased significantly after DHEA administration among older women
Jiangxi University of Traditional Chinese Medicine, February 14, 2021
According to news originating from Jiangxi, People’s Republic of China, research stated, “Despite the fact that numerous clinical studies have evaluated the positive effects of dehydroepiandrosterone (DHEA) supplementation on testosterone concentrations and on the body mass index (BMI), more evidence is needed to certify that DHEA is a BMI-reducing agent in the elderly. This meta-analysis aims to clarify the various incompatible results and investigate the impact of DHEA supplementation on serum testosterone levels and lean body mass in elderly women.”
Our news journalists obtained a quote from the research from the Jiangxi University of Traditional Chinese Medicine, “Four scientific databases (EMBASE, PubMed/MEDLINE, Scopus and Web of Science) were searched from inception until 20 August 2020 for trials comparing DHEA with placebo. Results were presented as weighted mean differences (WMDs) and 95 % confidence intervals (CIs) based on the random effects model (DerSimonian-Laird approach). Nine arms with 793 subjects reported testosterone as an outcome measure. The overall results demonstrated that testosterone levels increased significantly after DHEA administration in elderly women (WMD: 17.52 ng/dL, 95 % CI: 6.61, 28.43, P = 0.002). In addition, DHEA administration significantly decreased the BMI (WMD:-0.39 kg/m(2), I-2 = 0.0 %).”
According to the news editors, the research concluded: “The results of the current meta-analysis support the use of DHEA supplementation for increasing testosterone concentrations in elderly women.”
This research has been peer-reviewed.
 
How healthy lifestyle behaviours can improve cholesterol profiles
Harvard School of Public Health, February 15, 2021
Combining healthy lifestyle interventions reduces heart disease through beneficial effects on different lipoproteins and associated cholesterols, according to a study published February 9 in eLife.
Having a healthy lifestyle has long been associated with a lower risk of developing heart disease. The new study provides more detailed information on how healthy lifestyles improve cholesterol, and suggests that combining cholesterol-lowering medications and lifestyle interventions may yield the greatest benefits to heart health.
Cholesterol-lowering medications such as statins help reduce heart risks by lowering levels of low-density lipoprotein (LDL) cholesterol, the so-called "bad" cholesterol. Healthy lifestyle interventions, including exercising regularly, having a healthy diet, lowering alcohol consumption and maintaining a healthy weight, have also been shown to lower LDL as well as increase "healthy" high-density lipoprotein (HDL) cholesterol.
"Until now, no studies have compared the lipid-lowering effects of cholesterol-lowering medications and healthy lifestyle interventions side by side," says lead author Jiahui Si, Postdoctoral Research Fellow in the Department of Epidemiology at Harvard T.H. Chan School of Public Health, Boston, Massachusetts, US.
To address this gap, Si and colleagues used a technique called targeted nuclear magnetic resonance spectroscopy to measure 61 different lipid markers in blood samples from 4,681 participants in the China Kadoorie Biobank, including cases of stroke, coronary heart disease and healthy individuals. They studied lipid markers in the blood of participants who had multiple healthy lifestyle habits and compared them to those of participants with less healthy habits. They found 50 lipid markers associated with a healthy lifestyle.
When the team looked at a subset of 927 individuals who had coronary heart disease in the next 10 years and 1,513 healthy individuals, they found 35 lipid markers that showed statistically significant mediation effects in the pathway from healthy lifestyles to the reduction of heart disease. Together, the combined beneficial effects of the lipid changes associated with healthy lifestyle practices were linked to a 14% reduced risk of heart disease. Specifically, very-low-density lipoprotein (VLDL) and HDL levels in the blood were linked to the heart-protecting benefits of healthy lifestyles.
"Using a genetic scoring technique, we could compare the effect of cholesterol-lowering drugs with that of lifestyle side by side in the study participants," says co-senior author Liming Liang, Associate Professor of Statistical Genetics in the Department of Epidemiology at Harvard T.H. Chan School of Public Health. "Our analysis confirmed that cholesterol-lowering drugs would have the expected effect in lowering LDL cholesterol, but this is much weaker compared to the effect of healthy behaviours on VLDL cholesterol which also increases the risk of heart disease."
Overall, they found that taking cholesterol-lowering medications and engaging in multiple healthy lifestyles would likely help individuals to achieve the greatest heart-protecting benefits because of the complementary effects of the drugs and healthy behaviours.
"Lifestyle interventions and lipid-lowering medications may affect different components of the lipid profile, suggesting they are not redundant strategies but could be combined for improved benefits," concludes co-senior author Jun Lv, Professor at the Department of Epidemiology & Biostatistics at the School of Public Health, Peking University Health Science Center, Beijing, China.
 
Role of Diet in Colorectal Cancer IncidenceUmbrella Review of Meta-analyses of Prospective Observational Studies
University of Utah, February 16
Question  How credible is the evidence behind the association of dietary factors with colorectal cancer (CRC) risk in published meta-analyses of prospective observational studies?
Findings  This umbrella review of 45 meta-analyses describing 109 associations found convincing evidence for an association between lower CRC risk and higher intakes of dietary fiber, dietary calcium, and yogurt and lower intakes of alcohol and red meat.
Meaning  This study suggests that dietary factors may have a role in the development and prevention of CRC, but more research is needed on specific foods for which the evidence remains suggestive.
Abstract
Importance  Several meta-analyses have summarized evidence for the association between dietary factors and the incidence of colorectal cancer (CRC). However, to date, there has been little synthesis of the strength, precision, and quality of this evidence in aggregate.
Objective  To grade the evidence from published meta-analyses of prospective observational studies that assessed the association of dietary patterns, specific foods, food groups, beverages (including alcohol), macronutrients, and micronutrients with the incidence of CRC.
Data Sources  MEDLINE, Embase, and the Cochrane Library were searched from database inception to September 2019.
Evidence Review  Only meta-analyses of prospective observational studies with a cohort study design were eligible. Evidence of association was graded according to established criteria as follows: convincing, highly suggestive, suggestive, weak, or not significant.
Results  From 9954 publications, 222 full-text articles (2.2%) were evaluated for eligibility, and 45 meta-analyses (20.3%) that described 109 associations between dietary factors and CRC incidence were selected. Overall, 35 of the 109 associations (32.1%) were nominally statistically significant using random-effects meta-analysis models; 17 associations (15.6%) demonstrated large heterogeneity between studies (I2 > 50%), whereas small-study effects were found for 11 associations (10.1%). Excess significance bias was not detected for any association between diet and CRC. The primary analysis identified 5 (4.6%) convincing, 2 (1.8%) highly suggestive, 10 (9.2%) suggestive, and 18 (16.5%) weak associations between diet and CRC, while there was no evidence for 74 (67.9%) associations. There was convincing evidence of an association of intake of red meat (high vs low) and alcohol (≥4 drinks/d vs 0 or occasional drinks) with the incidence of CRC and an inverse association of higher vs lower intakes of dietary fiber, calcium, and yogurt with CRC risk. The evidence for convincing associations remained robust following sensitivity analyses.
Conclusions and Relevance  This umbrella review found convincing evidence of an association between lower CRC risk and higher intakes of dietary fiber, dietary calcium, and yogurt and lower intakes of alcohol and red meat. More research is needed on specific foods for which evidence remains suggestive, including other dairy products, whole grains, processed meat, and specific dietary patterns.
 
 
Pizza, burgers and the like: A single high-fat meal can damage  metabolism
Deutsches Diabetes-Zentrum (Germany), February 16, 2021
 
The global proliferation of overweight and obese people and people with type 2 diabetes is often associated with the consumption of saturated fats. Scientists at the German Diabetes Center (Deutsches Diabetes-Zentrum, DDZ) and the Helmholtz Center in Munich (HMGU) have found that even the one-off consumption of a greater amount of palm oil reduces the body's sensitivity to insulin and causes increased fat deposits as well as changes in the energy metabolism of the liver. The results of the study provide information on the earliest changes in the metabolism of the liver that in the long term lead to fatty liver disease in overweight persons as well as in those with type 2 diabetes.
 
In the current issue of the "Journal of Clinical Investigation", DZD researchers working at the German Diabetes Center, in conjunction with the Helmholtz Center in Munich and colleagues from Portugal, published a scientific investigation conducted on healthy, slim men, who were given at random a flavored palm oil drink or a glass of clear water in a control experiment. The palm oil drink contained a similar amount of saturated fat as two cheeseburgers with bacon and a large portion of French fries or two salami pizzas. The scientists showed that this single high-fat meal sufficed to reduce the insulin action, e.g. cause insulin resistance and increase the fat content of the liver. In addition, changes in the energy balance of the liver were proven. The observed metabolic changes were similar to changes observed in persons with type 2diabetes or non-alcoholic fatty liver disease (NAFLD). NAFLD is the most common liver disease in the industrial nations and associated with obesity, the so-called "metabolic syndrome," and is associated with an increased risk in developing type 2 diabetes. Furthermore, NAFLD in advanced stages can result in severe liver damage.
 
"The surprise was that a single dosage of palm oil has such a rapid and direct impact on the liver of a healthy person and that the amount of fat administered already triggered insulin resistance", explained Prof. Dr. Michael Roden, scientist, Managing Director and Chairman at the DDZ and the German Center for Diabetes Research (Deutsches Zentrum für Diabetesforschung, DZD). "A special feature of our study is that we monitored the liver metabolism of people with a predominantly non-invasive technology, e.g. by magnetic resonance spectroscopy. This allows us to track the storage of sugar and fat as well as the energy metabolism of the mitochondria (power plants of the cell)." Thanks to the new methods of investigation, the scientists were able to verify that the intake of palm oil affects the metabolic activity of muscles, liver and fatty tissue. The induced insulin resistance leads to an increased new formation of sugar in the liver with a concomitant decreased sugar absorption in the skeletal muscles - a mechanism that makes the glucose level rise in persons afflicted with type 2 diabetes and its pre-stages. In addition, the insulin resistance of the fatty tissue causes an increased release of fats into the blood stream, which in turn continues to foster the insulin resistance. The increased availability of fat leads to an increased workload for the mitochondria, which can in the long term overtax these cellular power plants and contribute to the emergence of a liver disease.
 
The team of Prof. Roden suspects that healthy people, depending on genetic predisposition, can easily manage this direct impact of fatty food on the metabolism. The long-term consequences for regular eaters of such high-fat meals can be far more problematic, however.
