“Roughly one-quarter of people living in the US carry a genetic variant of the apolipoprotein E gene, called APOE4, the most important genetic risk factor for Alzheimer's disease. Many lifestyle behaviors can mitigate risk, especially sleep hygiene, which provides an opportunity to rid the brain of toxic metabolic byproducts that can contribute to Alzheimer's disease risk.”
“But what does the science say? In this Aliquot, Dr. Jed Fahey and I discuss the pros and cons of eating meat as well as the confounding factors that may influence the risks associated with meat consumption.”
“Dietary fiber is a broad term that refers to the non-digestible components of fruits and vegetables. Gut microbes break down certain types of fiber, releasing micronutrients trapped in the fiber matrix and producing beneficial metabolic byproducts, such as short-chain fatty acids.”
“Naturally occurring forms of vitamin K include phylloquinone, known as vitamin K1, and a family of molecules called menaquinones, known as vitamin K2. In this Aliquot, Dr. Bruce Ames and I discuss the differences between (and dietary sources of) vitamins K1 and K2 and their effects on human health.”
“Consuming chocolate and cocoa may carry some risks, however, due to their cadmium content and possible effects on the fetus during pregnancy. In this Aliquot, I describe some of the research on the benefits and risks of consuming cocoa and chocolate, as foods or supplements.”
“Choline is particularly important during pregnancy and breastfeeding, but some evidence suggests that choline supplementation could carry some risks. In this Aliquot, I talk about the science surrounding choline.”
“Building muscle mass in one's early years is essential for staving off the age-related loss of muscle mass and may promote longevity. In this Aliquot, Dr. Stuart Phillips discusses the importance of building muscle through resistance training and why starting early is important.”
“Having sufficient muscle mass markedly reduces a person's risk of dying prematurely. Although some studies suggest that eating less protein promotes longevity, those studies might not take into account the periods of disuse and disability that often occur in real life.”
“Consuming sufficient protein is essential for muscle growth and maintenance. Emphasis on specific amino acids within protein, particularly the branched-chain amino acids, probably isn't necessary unless you're an elite athlete or an older adult.”
“Protein is essential for building and maintaining muscles. Aiming for about 1.2 to 1.6 grams of protein per kilogram of body weight (about 0.5 to 0.7 grams per pound) is optimal for maintenance on the lower end and building muscle on the higher end.”
