Hormonal changes during and after menopause have wide-ranging effects on health. A new cross-sectional study examined whether hormone replacement therapy (HRT) was associated with better cognitive performance in older women. The researchers analyzed existing data from 1,374 women aged 60 or older who took part in one of two rounds of a U.S. national health survey. They compared women who reported ever using estrogen, progesterone, or both for menopause with women who reported never using HRT. They also calculated the number of years from each woman's first period to menopause as a rough proxy... alzheimer's cognition dementia estrogen hormones
Read moreModern life keeps most people indoors, often under artificial lighting that differs greatly from natural daylight. Because light is the main signal that sets the body's internal clock, limited daylight exposure could affect metabolism. A new study tested whether working by a window, rather than under typical office lighting, changes blood sugar control and how the body uses energy in people with type 2 diabetes. The study involved 13 older adults with type 2 diabetes who completed two tightly controlled, 4.5-day stays in a research facility. During office hours (8:00 a.m. to 5:00 p.m.), parti... circadian rhythm diabetes

Watch now[toc position='left] Sodium plays a crucial role in human physiology, yet its consumption remains a topic of ongoing debate in health and nutrition science. While it is essential for maintaining fluid balance, nerve function, and muscle contractions, excessive intake has been linked to various adverse health effects, particularly cardiovascular disease and hypertension. The complexity of sodium's role in health arises from individual variability in salt sensitivity, lifestyle factors, and dietary habits. Sodium and Blood Pressure One of the most well-established relationships in nutrition scie... nutrition blood pressure cardiovascular obesity micronutrients salt
Read moreWhile brain aging is an inevitable part of growing older, lifestyle factors, particularly diet, can influence the rate at which this aging occurs. A recent study found that older adults with diets rich in omega-3 fatty acids, antioxidants, and vitamins demonstrate slower brain aging and better performance on cognitive tests. Researchers administered cognitive tests and brain imaging scans to 100 healthy older adults. They also measured 13 nutrition-related biomarkers in the participants' blood. They identified two brain aging patterns among the participants, with one group exhibiting acceler... nutrition diet aging omega-3 mental health vitamin e dementia

Watch nowParental abstention from alcohol reduces an infant's risk of being born with congenital heart disease. Congenital heart disease is an umbrella term for a range of heart conditions that are present at birth. Approximately 1 percent of all children worldwide (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7306355/) are born with the conditions. Findings from a 2019 meta-analysis suggest that parental abstention from alcohol reduces an infant's risk of being born with congenital heart disease. Alcohol elicits an array of harmful effects on the human body and is widely considered a toxin. Consuming... alcohol pregnancy
Read more[toc position='left'] Carotenoids are orange/yellow pigments in various foods, such as carrots, pumpkins, avocados, and salmon. While carotenoids are a highly diverse group of organic pigments, with over 1,100 known carotenoids [ref doi='10.1093/database/bax004'], this overview will focus on lutein and zeaxanthin, which are of particular interest due to their notable roles in eye and brain health. Carotenoids are one of the most common classes of bioactive compounds found in plants, along with alkaloids (e.g., berberine), organosulfur compounds (e.g., sulforaphane), and polyphenols (e.g., anth... carotenoids cholesterol eyes antioxidant
Read more[toc position='left'] Polyphenols comprise a group of antioxidant compounds found in a variety of plants consumed as foods and beverages. Polyphenols are one of the most common classes of bioactive compounds found in plants, along with alkaloids (e.g., berberine (https://www.foundmyfitness.com/topics/berberine)), organosulfur compounds (e.g., sulforaphane), and terpenoids (e.g., beta carotene). A growing body of evidence suggests that polyphenols have disease-fighting properties, although the evidence to support these claims varies in quality. Research has demonstrated some degree of efficacy ... polyphenol brain cancer heart disease green tea gut diet microbiome microbes
