“Practical exposure reduction can include avoiding heat with unsuitable plastic, using glass or stainless steel for hot foods and drinks when convenient, replacing damaged containers, and choosing fragrance-free personal-care products when feasible.”

“- Brad Schoenfeld, Ph.D. Highlighting a certain hypocrisy, Dr. Schoenfeld points out that while most parents won't blanch at their children participating in sports that are characterized by real risks of injury, they will often worry themselves unnecessarily about resistance training, which has fewer risks.”

“Dr. Rhonda Patrick describes a food routine built around adequate protein, vegetables, fruit, and fiber. In this clip from Q&A #84, she shares a personal protein minimum of 1.2 grams per kilogram of body weight daily and a usual intake closer to 1.3 to 1.4 grams.”

“Additionally, we also discuss the important role magnesium plays in preventing random mutations. "Men with the highest quartile of magnesium levels have a 40% decrease in all-cause mortality and a 50% decrease in deaths from cancer.".”

“Longer-term nutrient status offers another perspective: in a randomized trial of adults with overweight or obesity, 15 grams of psyllium daily for three months did not significantly alter serum micronutrient concentrations relative to control.”

“Moreover, taking mega doses (i.e. 400 IU/day) of alpha tocopherol has the unintended side-effect of actually depleting tissue levels of another important form of vitamin E that plays an anti-inflammatory role, known as gamma tocopherol.”

“Dr. Patrick explains that she uses zinc lozenges only during exposure or the earliest signs of illness, often totaling roughly 80 to 100 milligrams per day for a short period. Small randomized zinc-acetate lozenge trials have produced mixed results, with one reporting a shorter cold and another finding no faster recovery with more adverse effects.”

“A large meta-analysis found that protein supplementation improved resistance-training gains in muscle size and strength, with little additional lean-mass benefit above an estimated total intake of about 1.6 grams per kilogram per day for most participants.”

“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.”

“Emerging evidence suggests that IGF-1 also regulates the aging process via its influence on growth hormone. In this clip, Dr. Valter Longo describes the IGF-1 pathway and explains how defects in the pathway influence disease risk.”
