Fermented red clover extract stops menopausal hot flushes and symptoms

Aarhus University (Denmark), July 24, 2023

The vast majority of women in the menopause are familiar with the status of Red Clover as an herbal medicine that soothes hot flush symptoms and hormonal fluctuations. This holds true, new research shows, if the red clover is taken in a fermented form. Fermented Red Clover extract is demonstrated to decrease significantly both the number and severity of daily hot flushes.

The study also found that the extract prevents the normally accelerated menopausal bone loss affecting one in three women over the age of 50 (e.g. results showed treatment blunted bone loss in the spine completely). These findings are very promising as the benefits take place without any of the side effects of traditionally proscribed hormone therapies that increase the risk of cancers and cardiovascular diseases.

"It is the fermentation process of the Red Clover extract that makes the difference, as the lactic acid fermentation increases the bioavailability of the bioactive estrogen-like compounds (known as isoflavones or phytoestrogens) that Red Clover has in abundance," explains Max Norman Tandrup Lambert.

"The challenge with isoflavones is that they can be difficult to digest as they naturally occur in the plant bound to sugar molecules which prevent absorption. Hence, a large proportion of the isoflavones that are consumed (e.g. as a pill or capsule) can pass through the intestine without entering circulation. This problem is bypassed when the Red Clover extract undergoes a fermentation process. To be technical the process separates the sugar molecules from the isoflavones, thereby increasing bioavailability," explains Max Norman Tandup Lambert.

A studyrecruited 130 women with menopause symptoms, of which 60 were selected based on criteria of at least five severe hot flushes per day and blood tests (including FSH, that indicates the "stage" of menopause).

"The women were separated into two groups of 30, so 30 drank 150ml Red Clover extract per day for 12 weeks, whilst the other 30 drank a masked placebo product. After 12 weeks we tested again and were speechless about the data. There was a much greater effect than we had hoped for." Says Max Norman Tandrup Lambert.

 

Resveratrol, quercetin could provide new options for cancer therapy

Oregon State University, July 16, 2023

Resveratrol and quercetin, two polyphenols that have been widely studied for their health properties, may soon become the basis of an important new advance in cancer treatment, primarily by improving the efficacy and potential use of an existing chemotherapeutic cancer drug.

In laboratory experiments, researchers at Oregon State University have developed a system to increase the bioavailability of these compounds in the body by using "copolymers" that make them water soluble and allow their injection into the blood stream, creating levels that are far higher than could ever be obtained by diet or oral intake.

The resveratrol and quercetin then appear to reduce the cardiac toxicity of a very widely used cancer drug, Adriamycin. Although highly effective in the treatment of lymphomas, breast, ovarian and other cancers, Adriamycin can only be used for a limited time in humans because of its cardiotoxicity.

The co-administration of these polyphenols might allow much more extensive use of this drug, while at the same time improving its efficacy and demonstrating the polyphenols' own anti-cancer properties, scientists said.

Findings on this research have been published in the Journal of Controlled Release, by scientists from the College of Pharmacy at Oregon State University and the School of Pharmacy at Pacific University. Both institutions supported the research.

"The co-administration of high levels of resveratrol and quercetin, in both in vitro and in vivo studies, shows that it significantly reduces the cardiac toxicity of Adriamycin," Alani said. "And these compounds have a synergistic effect that enhances the efficacy of the cancer drug, by sensitizing the cancer cells to the effects of the drug."

It's possible, Alani said, that after further research it could be demonstrated that use of these compounds can completely eliminate the cardiotoxicity of Adriamycin, as they scavenge the toxic free radicals produced by use of this drug. It's also possible, he said, that administration of these natural polyphenols could have value in cancer therapy by themselves, or in combination with a wider range of other chemotherapeutic drugs.

 

World's largest study shows the more you walk, the lower your risk of death, even if you walk fewer than 5,000 steps

Medical University of Lodz (Poland) & Johns Hopkins University School of Medicine, August 8, 2023

The number of steps you should walk every day to start seeing benefits to your health is lower than previously thought, according to the largest analysis to investigate this.

The study, published in the European Journal of Preventive Cardiology, found that walking at least 3967 steps a day started to reduce the risk of dying from any cause, and 2337 steps a day reduced the risk of dying from diseases of the heart and blood vessels (cardiovascular disease).

However, the new analysis of 226,889 people from 17 different studies around the world has shown that the more you walk, the greater the health benefits. The risk of dying from any cause or from cardiovascular disease decreases significantly with every 500 to 1000 extra steps you walk. An increase of 1000 steps a day was associated with a 15% reduction in the risk of dying from any cause, and an increase of 500 steps a day was associated with a 7% reduction in dying from cardiovascular disease.

The researchers, led by Maciej Banach, Professor of Cardiology at the Medical University of Lodz, Poland, and Adjunct Professor at the Ciccarone Center for the Prevention of Cardiovascular Disease, Johns Hopkins University School of Medicine, found that even if people walked as many as 20,000 steps a day, the health benefits continued to increase. They have not found an upper limit yet.

"Our study confirms that the more you walk, the better," says Prof. Banach. "We found that this applied to both men and women, irrespective of age, and irrespective of whether you live in a temperate, sub-tropical or sub-polar region of the world, or a region with a mixture of climates. In addition, our analysis indicates that as little as 4,000 steps a day are needed to significantly reduce deaths from any cause, and even fewer to reduce deaths from cardiovascular disease."

There is strong evidence that a sedentary lifestyle may contribute to an increase in cardiovascular disease and a shorter life. Studies have shown that insufficient physical activity affects more than a quarter of the world's population. More women than men (32% versus 23%), and people in higher income countries compared to low-income countries (37% versus 16%) do not undertake a sufficient amount of physical activity.

The studies analyzed by the researchers followed up participants for a median (average) of seven years. The mean (average) age was 64, and 49% of participants were female.

In people aged 60 years or older, the size of the reduction in risk of death was smaller than that seen in people aged younger than 60 years. In the older adults, there was a 42% reduction in risk seen in those who walked between 6,000 and 10,000 steps a day, while there was a 49% reduction in risk in younger adults who walked between 7,000 and 13,000 steps a day.

 

Brains of overweight people 'ten years older' than lean counterparts at middle-age

University of Cambridge, August 4, 2023

From middle-age, the brains of obese individuals display differences in white matter similar to those in lean individuals ten years their senior, according to new research led by the University of Cambridge. White matter is the tissue that connects areas of the brain and allows for information to be communicated between regions.

 

Our brains naturally shrink with age, but scientists are increasingly recognising that obesity - already linked to conditions such as diabetes, cancer and heart disease - may also affect the onset and progression of brain ageing; however, direct studies to support this link are lacking.

 

The team studied data from 473 individuals between the ages of 20 and 87, recruited by the Cambridge Centre for Aging and Neuroscience.  The researchers divided the data into two categories based on weight: lean and overweight. They found striking differences in the volume of white matter in the brains of overweight individuals compared with those of their leaner counterparts. Overweight individuals had a widespread reduction in white matter compared to lean people.

 

They discovered that an overweight person at, say, 50 years old had a comparable white matter volume to a lean person aged 60 years, implying a difference in brain age of 10 years. Strikingly, however, the researchers only observed these differences from middle-age onwards, suggesting that our brains may be particularly vulnerable during this period of ageing.

 

"As our brains age, they naturally shrink in size, but it isn't clear why people who are overweight have a greater reduction in the amount of white matter," says first author Dr Lisa Ronan from the Department of Psychiatry at the University of Cambridge, "We can only speculate on whether obesity might in some way cause these changes or whether obesity is a consequence of brain changes."

 

 

 

Soy protein found to deplete testosterone in men

University of Connecticut, July 27, 2023 

The health detriments of soy consumption are reiterated in a new study out of the University of Connecticut that highlights the importance of avoiding soy at all costs. Researchers from the school found that men who consume soy protein rather than whey protein for muscle recovery and growth experience considerable reductions in their testosterone levels, as well as marked increases in levels of the stress hormone cortisol.

Published in the Journal of the American College of Nutrition (JACN), the randomized, placebo-controlled crossover study looked at how soy supplementation affects testosterone, cortisol and sex hormone-binding globulin (SHBG) levels in men who engage in resistance exercises and training. They compared these effects to those brought about in men who supplement with whey.

For the research, 10 resistance-trained men in their early 20s had their hormones evaluated in conjunction with an assigned supplemental diet. The men were divided into three groups: one receiving whey protein isolate, one receiving soy protein isolate and the last receiving a maltodextrin-based placebo control. The men were not allowed to take any other supplements, and vegetarians, vegans and individuals who were consuming high-protein diets were excluded.

For two weeks, the men were told to ingest 20 grams of their assigned supplement every morning at the same time. The participants were then instructed to perform six sets of heavy resistance squats at 10 reps each, exerting 80 percent of their maximum lifting weight. At the end of the 14-day period, the researchers collected hormone profiles from each of the men and made comparisons.

They found that, compared to the men who supplemented with whey, those taking soy did not necessarily produce more estrogen. They did, however, experience decreased testosterone levels and elevated cortisol levels, a deadly combination that can leave men at risk of disease and weight gain.

Lowered testosterone levels and elevated cortisol levels are also generally attributed to the feminization phenomenon occurring in men that sometimes leads to disorders like nipple discharge, breast enlargement and hot flashes. It can also lead to inhibited thyroid function, bone loss, sleeping disorders, decreased sex function and reproductive problems.

 

 

Study shows endometriosis is linked to higher risk of depression, anxiety, eating disorders

Yale University, August 7, 2023

Endometriosis is not just a condition that affects the pelvis, but a systemic disease that involves the entire body. Now, the largest epidemiological study to date on the psychiatric factors that can accompany endometriosis has demonstrated that depression, anxiety, and eating disorders are not only a result of the chronic pain endometriosis generates, but also have their own underlying genetic mechanisms. The team published its findings in JAMA Network Open.

"The relationship between endometriosis and mental health is more complicated than we expected," says Renato Polimanti, Ph.D., associate professor of psychiatry and the study's principal investigator. "The biological basis is not just chronic pain, and there is much more that we need to understand."

Endometriosis is an extremely painful condition in which tissue similar to the lining of the uterus (endometrium) grows outside the uterus. The disease manifests in a wide array of symptoms including pelvic, abdominal, and low back pain, heavy bleeding, painful sexual intercourse, painful urination and bowel movements, constipation or diarrhea, bloating, nausea, fatigue, and infertility.

In this new study, the Yale research team obtained data from the UK Biobank which included more than 8,200 patients with endometriosis and 194,000 healthy controls.

First, they investigated if depression, anxiety, and eating disorders were more prevalent in those with endometriosis, accounting for chronic pain, socioeconomic status, age, body mass index, various medications, and co-morbid conditions. They found that having endometriosis significantly increases the odds of having these three psychiatric conditions.

through running a genetic correlation analysis, they found a significantly high genetic correlation between endometriosis and each of the three disorders.
