“A meta-analysis of 49 studies involving 1,863 adults found that protein supplementation during prolonged resistance training produced additional gains in one-repetition maximum strength, fat-free mass, and muscle size compared with training alone.”

“Whereas fasting turns off multiple pathways associated with aging, such as mTOR and IGF-1, eating for optimal fitness activates these important processes. The IGF-1 pathway, in particular, plays key roles in growth and is strongly associated with cancer.”

“The excerpt also reviews controlled muscle studies: omega-3 attenuated loss during immobilization and increased the amino-acid-stimulated muscle-protein-synthesis response under tested conditions. These findings do not generalize to every dose or population.”

“In the prospective Framingham Offspring Study, people in the highest red-blood-cell DHA group had approximately 49 percent lower risk of developing Alzheimer's disease than those in the lowest group.”

“A large meta-analysis found that organic crops tended to contain higher concentrations of several phenolic compounds, lower cadmium, and fewer detectable pesticide residues, but no single nutritional pattern applies to every fruit or vegetable.”

“A large observational study associated five healthy lifestyle factors, including a healthy dietary pattern, with an estimated 14 additional years of life expectancy for women and 12 years for men at age 50 compared with following none of the factors.”

“A second randomized trial found that a single vitamin D3 dose taken with food increased vitamin D status, with a larger rise when the meal contained at least 15 grams of fat. These findings support taking vitamin D with a meal that contains some fat.”

“In this clip from Dr. Rhonda Patrick's appearance on Next Question with Katie Couric, she explains how sustained exercise can improve cardiovascular fitness and the heart's ability to fill efficiently during middle age.”

“In later randomized trials, urolithin A improved some laboratory measures of muscle endurance or hamstring strength, but it did not significantly improve key primary outcomes such as six-minute walk distance, muscle ATP production, or peak power.”

“Large treadmill cohorts associate higher measured fitness with lower mortality, while a 46-year study of middle-aged men linked the highest fitness category with about 4.9 additional estimated life-years compared with the lowest category.”
