Eggs contain several nutrients tied to brain health, but whether egg intake relates to Alzheimer's disease risk is less clear. A large observational study examined whether egg intake was associated with later Alzheimer's disease diagnoses in older adults. Researchers analyzed data from 39,498 participants in the Adventist Health Study-2. In the main analysis, they grouped participants by how often they ate eggs as a standalone food, such as boiled, scrambled, fried; in omelets; or as egg salad, and compared each group with those who never or rarely ate eggs this way. A separate analysis treate... alzheimer's diet
Read moreEating walnuts prevents premature death and extends life expectancy. Walnuts are a nutrient-dense food, rich in omega-3 fatty acids, protein, fiber, and many vitamins and minerals. Evidence suggests that consuming walnuts as part of a healthy diet improves cognitive function (https://www.sciencedirect.com/science/article/abs/pii/S1043661817311751) and cardiovascular health (https://academic.oup.com/jn/article/144/4/547S/4571627?login=true) and reduces the risk of developing certain types of cancer (https://www.tandfonline.com/doi/abs/10.1080/01635581.2014.956246). Findings from a 2021 study s... nutrition mortality
Read moreEvidence suggests that sperm quality in males over the past 50-70 years has declined, likely due to a combination of dietary and lifestyle factors and exposure to endocrine-disrupting chemicals. For example, diets rich in processed meats, full fat dairy, and sugar-sweetened beverages are associated with poor sperm quality, whereas diets rich in vitamins, minerals, and unsaturated fats improve sperm quality and fertility. Results of a recent observational study demonstrate the effects of fish oil supplementation on sperm quality and testicular function in healthy young males. Infertility affect... omega-3 testosterone supplements

Watch nowAn estimated 4.2 million deaths each year (https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(16)31679-8/fulltext), many of which are cardiovascular disease-related, are associated with exposure to air pollution. The mechanisms that drive this association include systemic inflammation, endothelial dysfunction, oxidative stress, hypertension, and metabolic dysfunction. Findings from a recent study suggest that supplemental omega-3 fatty acids may reduce the risk of cardiovascular disease-related death associated with exposure to particulate air pollutants. Particulate matter in ai... omega-3 glutathione protein dairy
Read moreA 28% lower risk of dementia and better scores on tests for memory and linguistic abilities was associated with a high intake of dietary phosphatidylcholine mainly from eggs and meat in men. Choline is an important precursor to the neurotransmitter acetylcholine which plays an important role in cognition. Phosphatidylcholine is a very important component of cell membranes that make up neurons and also combines with the omega-3 fatty acid DHA to form lysophosphatidylcholine DHA which is transported across the blood-brain barrier. I published a paper last year on the important role DHA in phosph... alzheimer's omega-3 dementia acetylcholine neurons
