“In an early randomized workplace study, healthy employees who completed an eight-week mindfulness program showed a greater rise in antibodies after influenza vaccination than a waitlist group.”

“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.”

“In a crossover study of 15 healthy adults, a single 0.35-gram-per-kilogram dose during acute sleep deprivation changed brain-energy metabolites and improved selected cognitive tasks.”

“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.”
