Strawberries improve cognition in a randomized, double-blind, placebo-controlled trial of older adults

Tufts University, August 8, 2021

According to news originating from Boston, Massachusetts, research stated, “Functional changes in the brain during ageing can alter learning and memory, gait and balance - in some cases leading to early cognitive decline, disability or injurious falls among older adults. Dietary interventions with strawberry (SB) have been associated with improvements in neuronal, psychomotor and cognitive functions in rodent models of ageing.”

Our news journalists obtained a quote from the research from Tufts University, “We hypothesised that dietary supplementation with SB would improve mobility and cognition among older adults. In this study, twenty-two men and fifteen women, between the ages of 60 and 75 years, were recruited into a randomised, double-blind, placebo-controlled trial in which they consumed either freeze-dried SB (24 g/d, equivalent to two cups of fresh SB) or a SB placebo for 90 d. Participants completed a battery of balance, gait and cognitive tests at baseline and again at 45 and 90 d of intervention. Significant supplement group by study visit interactions were observed on tests of learning and memory. Participants in the SB group showed significantly shorter latencies in a virtual spatial navigation task (P = 0.020,.p2 = 0.106) and increased word recognition in the California Verbal Learning test (P = 0.014,.p2 = 0.159) across study visits relative to controls. However, no improvement in gait or balance was observed.”

According to the news editors, the research concluded: “These findings show that the addition of SB to the diets of healthy, older adults can improve some aspects of cognition, but not gait or balance, although more studies with a larger sample size and longer follow-up are needed to confirm this finding.”

This research has been peer-reviewed.

 

Growing evidence of vitamin K benefits for heart health

Edith Cowan University (Australia), August 10, 2021

New Edith Cowan University (ECU) research has found that people who eat a diet rich in vitamin K have up to a 34 percent lower risk of atherosclerosis-related cardiovascular disease (conditions affecting the heart or blood vessels).

Researchers examined data from more than 50,000 people taking part in the Danish Diet, Cancer, and Health study over a 23-year period. They investigated whether people who ate more foods containing vitamin K had a lower risk of cardiovascular disease related to atherosclerosis (plaque build-up in the arteries).

There are two types of vitamin K found in foods we eat: vitamin K1 comes primarily from green leafy vegetables and vegetable oils while vitamin K2 is found in meat, eggs and fermented foods such as cheese.

The study found that people with the highest intakes of vitamin K1 were 21 percent less likely to be hospitalized with cardiovascular disease related to atherosclerosis.

For vitamin K2, the risk of being hospitalized was 14 percent lower.

This lower risk was seen for all types of heart disease related to atherosclerosis, particularly for peripheral artery disease at 34 percent.

ECU researcher and senior author on the study Dr. Nicola Bondonno said the findings suggest that consuming more vitamin K may be important for protection against atherosclerosis and subsequent cardiovascular disease.

"Current dietary guidelines for the consumption of vitamin K are generally only based on the amount of vitamin K1 a person should consume to ensure that their blood can coagulate," she said.

"However, there is growing evidence that intakes of vitamin K above the current guidelines can afford further protection against the development of other diseases, such as atherosclerosis.

"Although more research is needed to fully understand the process, we believe that vitamin K works by protecting against the calcium build-up in the major arteries of the body leading to vascular calcification."

University of Western Australia researcher Dr. Jamie Bellinge, the first author on the study, said the role of vitamin K in cardiovascular health and particularly in vascular calcification is an area of research offering promising hope for the future.

"Cardiovascular disease remains a leading cause of death in Australia and there's still a limited understanding of the importance of different vitamins found in foodand their effect on heart attacks, strokes and peripheral artery disease," Dr. Bellinge said.

"These findings shed light on the potentially important effect that vitamin K has on the killer disease and reinforces the importance of a healthy diet in preventing it."

Dr. Bondonno said that while databases on the vitamin K1 content of foods are very comprehensive, there is currently much less data on the vitamin K2 content of foods. Furthermore, there are 10 forms of vitamin K2 found in our diet and each of these may be absorbed and act differently within our bodies.

"The next phase of the research will involve developing and improving databases on the vitamin K2 content of foods.

"More research into the different dietary sources and effects of different types of vitamin K2 is a priority," Dr. Bondonno said.

Additionally, there is a need for an Australian database on the vitamin K content of Australian foods (e.g. vegemite and kangaroo).

To address this need, Dr. Marc Sim, a collaborator on the study, has just finished developing an Australian database on the vitamin K content of foods which will be published soon.

The paper "Vitamin K intake and atherosclerotic cardiovascular disease in the Danish Diet Cancer and Health Study' was published in the Journal of the American Heart Association.

High BMI causes depression, both physical and social factors play a role

University of Exeter (UK), August 9, 2021

A large-scale study provides further evidence that being overweight causes depression and lowers wellbeing and indicates both social and physical factors may play a role in the effect.

With one in four adults estimated to be obese in the UK, and growing numbers of children affected, obesity is a global health challenge. While the dangers of being obese on physical health is well known, researchers are now discovering that being overweight can also have a significant impact on mental health. 

The new study, published in Human Molecular Genetics, sought to investigate why a body of evidence now indicates that higher BMI causes depression. The team used genetic analysis, known as Mendelian Randomisation, to examine whether the causal link is the result of psychosocial pathways, such as societal influences and social stigma, or physical pathways, such as metabolic conditions linked to higher BMI. Such conditions include high blood pressure, type 2 diabetes and cardiovascular disease.

In research led by the University of Exeter and funded by the Academy of Medical Sciences, the team examined genetic data from more than 145,000 participants from the UK Biobank with detailed mental health data available. In a multifaceted study, the researchers analyzed genetic variants linked to higher BMI, as well as outcomes from a clinically-relevant mental health questionnaire designed to assess levels of depression, anxiety and wellbeing.

To examine which pathways may be active in causing depression in people with higher BMI, the team also interrogated two sets of previously discovered genetic variants. One set of genes makes people fatter, yet metabolically healthier, meaning they were less likely to develop conditions linked to higher BMI, such as high blood pressure and type 2 diabetes. The second set of genes analyzed make people fatter and metabolically unhealthy, or more prone to such conditions. The team found little difference between the two sets of genetic variants, indicating that both physical and social factors play a role in higher rates of depression and poorer wellbeing.

Lead author Jess O'Loughlin, at the University of Exeter Medical School, said: "Obesity and depression are both major global health challenges, and our study provides the most robust evidence to date that higher BMI causes depression. Understanding whether physical or social factors are responsible for this relationship can help inform effective strategies to improve mental health and wellbeing. Our research suggests that being fatter leads to a higher risk of depression, regardless of the role of metabolic health. This suggests that both physical health and social factors, such as social stigma, both play a role in the relationship between obesity and depression."

Lead author Dr. Francesco Casanova, of the University of Exeter Medical School, said, "This is a robust study, made possible by the quality of UK Biobank data. Our research adds to a body of evidence that being overweight causes depression. Finding ways to support people to lose weight could benefit their mental health as well as their physical health."

The study, titled "Higher adiposity and mental health: causal inference using Mendelian Randomisation," is published in Human Molecular Genetics.

 

Protective effects of saffron compound against amyloid beta-induced neurotoxicity

Guangdong Medical University (China), August 4, 2021

According to news reporting from Dongguan, People’s Republic of China, research stated, “Alzheimer’s disease (AD) is a most common neurodegenerative disorder worldwide. Because of its complex pathogenesis, the prevention and therapies of AD still are a severe challenge.”

The news correspondents obtained a quote from the research from Guangdong Medical University, “Evidence suggested that crocin, the major component of saffron, exhibited neuroprotective effects in AD. As such, in this study, N2a/APP695swe cells were enrolled to investigate the effects of crocin on endogenous A beta-induced neurotoxicity. Crocin (100 and 200 mu M) could ameliorate cytotoxicity according to CCK-8 assay and reduce apoptosis in line with Hoechst 33,342 staining and Annexin V-FITC/PI double staining in N2a/APP695swe cells. Reduced ROS generation and elevated MMP were found in N2a/APP695swe cells treated with crocin (100 and 200 mu M). Additionally, crocin at concentrations of 100 and 200 mu M inhibited the release of cytochrome and attenuated caspases-3 activity in N2a/APP695swe cells. Furthermore, succinylation, crotonylation, 2-hydroxyisobutyrylation, malonylation, and phosphorylation were significantly reduced, while a slight increase of acetylation was found in 100-mu M crocin treated N2a/APP695swe cells.”

According to the news reporters, the research concluded: “Taken together, crocin may be a promising natural product candidate for the effective cure of AD.”

This research has been peer-reviewed.

 

Microbes have potential to reverse aging in the brain

University College Cork (Ireland), August 10, 2021

Microbiome Ireland, a world leading SFI Research Centre, have found that aging-associated changes in the immune system of old mice were reversed by the transfer of gut microbiota from the young mice.

Research from APC Microbiome Ireland (APC) at University College Cork (UCC) published today in the leading international scientific journal Nature Agingintroduces a novel approach to reverse aspects of aging-related deterioration in the brain and cognitive function via the microbes in the gut.

As our population ages one of the key global challenges is to develop strategies to maintain healthy brain function. This ground-breaking  research opens up a potentially new therapeutic avenues  in the form of microbial-based interventions to slow down brain aging and associated cognitive problems. 

The work was carried out by researchers in the Brain-Gut-Microbiota lab in APC led by Prof John F. Cryan, Vice President for Research & Innovation, University College Cork as well as a Principal Investigator at APC Microbiome Ireland  an SFI Research Centre,  based in in University College Cork and Teagasc Moorepark.

There is a growing appreciation of the importance of the microbes in the gut on all aspects of physiology and medicine. In this latest mouse study the authors show that by transplanting microbes from young into old animals they could rejuvenate aspects of brain and immune function. Prof John F. Cryan, says "Previous research published by the APC and other groups internationally has shown that the  gut microbiome plays a key role in aging and the aging process. This new research is a potential game changer , as we have established that the microbiome can be harnessed to reverse age-related brain deterioration. We also see evidence of improved learning ability and cognitive function". Although very exciting Cryan cautions that "it is still early days and much more work is needed to see how these findings could be translated in humans".  

APC Director Prof Paul Ross stated that "This research of Prof. Cryan and colleagues further demonstrates the importance of the gut microbiome in many aspects of health, and particularly across across the brain/gut axis where brain functioning can be positively influenced. The study opens up possibilities in the future to modulate gut microbiota as a therapeutic target to influence brain health" The study was led by co-first authors Dr. Marcus Boehme along with Ph.D. students Katherine E. Guzzetta, and Thomaz Bastiaansen.

Even quick meditation aids cognitive skills

Yale University & Swarthmore College, August 7, 2018 

College students who listen to a 10-minute meditation tape complete simple cognitive tasks more quickly and accurately than peers who listen to a "control" recording on a generic subject, researchers at Yale University and Swarthmore College report.

The study, published in the journal Frontiers of Neuroscience, shows even people who have never meditated before can benefit from even a short meditation practice.

"We have known for awhile that people who practice meditation for a few weeks or months tend to perform better on cognitive tests, but now we know you don't have to spend weeks practicing to see improvement," said Yale's Hedy Kober, associate professor of psychiatry and psychology and senior author of the study.

The research team headed by Kober and Catherine Norris at Swarthmore randomly divided college students into two groups. One group listened to a 10-minute recording on meditation prior to performing cognitive tests and the second group listened to a similarly produced tape about sequoia trees.

Both groups were then given simple tasks designed to measure cognitive dexterity. Those who listened to the meditation recording performed significantly better, across two studies.

There was one exception, however. Those who scored highest in measurements of neuroticism—"I worry all the time"—did not benefit from listening to the meditation tape.

"We don't know if longer meditation sessions, or multiple sessions, would improve their cognitive scores, and we look forward to testing that in future studies," Kober said.

 

Physical activity protects children from the adverse effects of digital media on their weight later in adolescence

University of Helsinki (Finland), August 9, 2021

 

Children's heavy digital media use is associated with a risk of being overweight later in adolescence. Physical activity protects children from the adverse effects of digital media on their weight later in adolescence.

A recently completed study shows that six hours of leisure-time physical activity per week at the age of 11 reduces the risk of being overweight at 14 years of age associated with heavy use of digital media.

Obesity in children and adolescents is one of the most significant health-related challenges globally. A study carried out by the Folkhälsan Research Center and the University of Helsinki investigated whether a link exists between the digital media use of Finnish school-age children and the risk of being overweight later in adolescence. In addition, the study looked into whether children's physical activity has an effect on this potential link.

The results were published in the Journal of Physical Activity and Health.

More than six hours of physical activity per week appears to reverse adverse effects of screen time

The study involved 4,661 children from the Finnish Health in Teens (Fin-HIT) study. The participating children reported how much time they spent on sedentary digital media use and physical activity outside school hours. The study demonstrated that heavy use of digital media at 11 years of age was associated with a heightened risk of being overweight at 14 years of age in children who reported engaging in under six hours per week of physical activity in their leisure time. In children who reported being physically active for six or more hours per week, such a link was not observed.

The study also took into account other factors potentially impacting obesity, such as childhood eating habits and the amount of sleep, as well as the amount of digital media use and physical activity in adolescence. In spite of the confounding factors, the protective role of childhood physical activity in the connection between digital media use in childhood and being overweight later in life was successfully confirmed.

"The effect of physical activity on the association between digital media use and being overweight has not been extensively investigated in follow-up studies so far," says Postdoctoral Researcher Elina Engberg.

Further research is needed to determine in more detail how much sedentary digital media use increases the risk of being overweight, and how much physical activity is needed, and at what intensity, to ward off such a risk. In this study, the amount of physical activity and use of digital media was reported by the children themselves, and the level of their activity was not surveyed, so there is a need for further studies.

"A good rule of thumb is to adhere to the physical activity guidelines for children and adolescents, according to which school-aged children and adolescents should be physically active in a versatile, brisk and strenuous manner for at least 60 minutes a day in a way that suits the individual, considering their age," says Engberg. In addition, excessive and extended sedentary activity should be avoided.
