“Dr. Rhonda Patrick discusses the differences between different forms of DHA in terms of bioavailability and transport into different cells. She talks about why a specific type of DHA (DHA in phosphatidylcholine) is more readily transported into the brain because it forms DHA-lysophsophatidylcholine.”

“Although some evidence suggests that black, caffeinated coffee or tea may have little effect on the beneficial effects associated with time-restricted eating, experts in the field of circadian biology suggest a more conservative approach that permits coffee and tea only during the designated window of eating.”

“Lunch varied among sardines, mackerel, wild salmon, avocado, nuts, fruit, cheese, and quinoa salad, giving her flexible sources of protein, marine fats, fiber, and fermented foods. Dinner typically paired fish, chicken, or occasional beef with vegetables or salad.”

“A larger randomized-trial meta-analysis also found modest average reductions in BMI, waist circumference, and body-fat percentage, although protocols and populations varied. These averages do not mean that HIIT alone guarantees fat loss.”

“His lab also developed a technique for harvesting 5 to 7 times more hematopoietic stem cells from placenta than is currently retrieved from cord blood, a more standard, established source that is used worldwide for bone-marrow transplant.”

“When produced during exercise (especially high intensity workouts like cycling, which shifts metabolism toward glycolysis to more quickly meet the high energetic demands), lactate switches on more than 600 genes involved in muscle adaptation, stimulates mitochondrial biogenesis – the process of making new mitochondria – and promotes protein synthesis, which is essential for muscle growth.”

“Mouse studies of feeding during infection also found different responses across bacterial and viral models, so a minimally processed dietary pattern, regular exercise, and normal hydration and nutrition during illness provide a more useful foundation than one universal food or fasting rule.”

“A small randomized trial in trained athletes found that 20 milligrams per day for two weeks increased total antioxidant capacity and glutathione peroxidase and reduced post-training DNA damage versus placebo; it did not test performance or long-term adaptation.”

“While it’s likely that there may be more going on with depression than just inflammation by itself, it could be an incredibly useful lens through which to look at promising avenues to potentially treat or prevent it, since controlling systemic inflammation shows promise as being both important for longevity and health in general.”

“More importantly, however, these effects were sustained – even after several months – demonstrating that sulforaphane did not exhaust the body's capacity to protect itself from environmental threats and suggesting that regular consumption of sulforaphane in foods or dietary supplements provides a kind of nutritional "seatbelt" that protects against future toxic exposures.”
