Plant-Based Proteins Significantly Reduce Chronic Disease Risk in Women, Tufts University Study Finds

Chronic Disease Risk in Women

In a groundbreaking study published this week by The American Journal of Clinical Nutrition, researchers from Tufts University discovered that a diet rich in protein, especially plant-based protein, substantially reduces the chronic disease risk in women. The findings emphasize the potential of dietary choices in promoting long-term health and well-being.

The research, led by scientist Andres Ardisson Korat, focused on analyzing self-reported data from over 48,000 women. These participants, all healthcare professionals, were part of a long-term study spanning from 1984 to 2016. At the study’s commencement, the women were between the ages of 38 and 59, exhibiting good physical and mental health.

Korat highlighted the pivotal role of protein consumption in midlife, stating, “Consuming protein in midlife was linked to promoting good health in older adulthood.” The study revealed that the source of protein matters, with plant-based proteins showing a significant positive impact on health outcomes.

Plant Proteins For Reducing Chronic Disease Risk in Women

The results showcased a clear distinction between the effects of plant-based proteins and animal proteins on health. Participants who incorporated more plant-based proteins from sources like fruits, vegetables, legumes, and beans demonstrated a lower risk of developing ailments such as diabetes, cancer, and heart disease. Notably, these individuals exhibited lower levels of “bad” cholesterol (LDL cholesterol), improved blood pressure, and enhanced insulin sensitivity.

Popular sources of plant-based protein include lentils, beans, peas, spinach, and broccoli, emphasizing the accessibility of these health benefits through everyday food choices.

On the contrary, those who consumed higher amounts of animal proteins, including beef, chicken, milk, fish/seafood, and cheese, were associated with a 6% lower likelihood of maintaining good health as they aged. Animal protein consumption was linked to higher levels of “bad” cholesterol, raising concerns about its impact on overall health.

The study’s longitudinal approach provided valuable insights into the long-term health impact of protein choices. Those who prioritized plant-based proteins in their diet were found to be 46% more likely to maintain good health in their later years.

“Those who consumed greater amounts of animal protein tended to have more chronic disease and didn’t manage to obtain the improved physical function that we normally associate with eating protein,” Korat explained, underlining the potential downsides of relying heavily on animal-based protein sources.

While the study predominantly involved white participants, Korat acknowledged the need for further research to explore the effectiveness of plant-based protein across diverse racial demographics. He emphasized that the field is evolving and additional studies with more varied cohorts would be valuable.

In light of the study’s compelling results, experts suggest considering additional plant-based protein sources in daily diets. Foods such as beans and spinach offer not only nutritional benefits but also contribute to overall health and longevity.

“Dietary protein intake, especially plant protein, in midlife, plays an important role in the promotion of healthy aging and in maintaining positive health status at older ages,” stated Korat, summarizing the potential impact of dietary choices on the aging process.

As research continues to uncover the intricate connections between diet and health, incorporating plant-based proteins may emerge as a key strategy for promoting longevity and preventing chronic diseases among women.

In conclusion, the Tufts University study underscores the importance of considering the source of protein in one’s diet, with plant-based options showing a clear advantage in supporting healthy aging for women.

New Study Reveals Link Between Depression, Anorexia, and Gut Microbiota

Chronic Disease Risk in Women

A recent study published in BMC Psychiatry sheds light on a potential connection between major depressive disorder (MDD), anorexia, and gut microbiota. Led by researchers at the First Hospital of Shanxi Medical University, the study suggests that individuals with both depression and anorexia exhibit distinct patterns in their gut bacteria, particularly involving the presence of a specific bacterium called Blautia.

Depression, characterized by persistent sadness and a loss of interest in daily activities, affects millions worldwide and is often accompanied by a high risk of suicide. Anorexia, marked by reduced appetite and distorted body image, commonly co-occurs with depression, complicating treatment efforts.

Stress can affect our lives in many ways, from our mental health to our relationships, but it can also lead to physical symptoms such as ‘cortisol belly’. Cortisol belly, named after the stress hormone, has been widely discussed on social platforms such as TikTok, with users and experts explaining how it occurs, and theorizing what could be done about it.

While you may not have heard of the term ‘cortisol belly’ before, you might have heard of stubborn belly fat or stress belly, which are essentially the same thing. This is because it refers to the accumulation of visceral adipose tissue around the stomach, which has been linked to prolonged exposure to elevated levels of the stress hormone, cortisol.
