“In a small immobilization trial, five grams per day of omega-3 fatty acids reduced the loss of muscle volume in young women compared with sunflower oil, supporting continued research on omega-3s and disuse atrophy. Heat is the fourth proposed tool.”

“The question of whether NAD+ is derived directly from NR or NMN in certain tissues rather than being salvaged from nicotinamide may, in particular, have implications for whether or not oral administration may be hampered in achieving maximal NAD+ status due to the fact that the process of salvaging NAD+ from nicotinamide is subject to feedback inhibition.”

“Dr. Patrick therefore favors lower-risk tools for focus, including high-quality sleep, exercise, cocoa flavanols, deliberate cold exposure, and modest caffeine, before considering an addictive stimulant. Nicotine is not equivalent to tobacco smoke, but that does not make chronic use benign.”

“A randomized-trial meta-analysis found a higher atrial-fibrillation risk with marine omega-3 supplementation, with a stronger signal at doses above 1 gram per day; the included populations generally had cardiovascular disease or elevated cardiovascular risk.”

“EPA and DHA play particularly important roles in heart health because they participate in pathways involved in the production of hormones that regulate blood clotting and inflammation, help maintain healthy heart rhythms, and influence the contraction and relaxation of arteries.”

“Dr. Bruce Ames' Triage Theory Dr. Ames proposed that the body does a strategic rationing so that those proteins and enzymes in the body which are essential for short-term survival get their share of vitamins and minerals at the expense of other proteins and enzymes that are essential for long-term survival.”

“A few examples of genes with common polymorphism discussed are MTHFR and folate, NBPF3 and vitamin B6, FUT2 and vitamin B12, BCMO1 and beta-carotene, FADS2 and omega-3 fatty acids, CYP2R1 and vitamin D, PEMT and choline as well as APOE4 and FOXO3.”

“The effects of heat exposure are broad and include improved immunity, better cardiovascular health, improved mood, and extended healthspan, the number of years we live in good health. Rhonda shares her personal sauna bathing routine and briefly describes special considerations for children and other special groups.”

“Specific topics include autophagy, the process of recycling dysfunctional cells that is induced by fasting and fasting-mimicking drugs such as resveratrol and spermidine. Rhonda discusses the effects of fasting on Parkinson's disease and which groups of people should not fast.”

Dr. Rhonda Patrick answers audience questions on various health, nutrition, and science topics in this Q&A session.
