# Nutritional Modulation

Eating patterns, fasting protocols, macronutrient frames, and food-class effects with operational doses and evidence tiers. The 'what to eat and when' chapter.

Start with [Time-Restricted Eating](time-restricted-eating.md), [Protein Intake for Sarcopenia Prevention](sarcopenia-protein-intake.md), [Mediterranean Diet Pattern](mediterranean-diet-pattern.md), [MIND Diet Pattern](mind-diet-pattern.md), [Fasting-Mimicking Diet](fasting-mimicking-diet.md), and [Caloric Restriction](caloric-restriction.md), then use the adjacent entries to separate daily eating windows from multi-day fasting cycles, sustained energy reduction, diet-quality patterns, cognitive-aging food patterns, [food-level polyphenol exposure](polyphenol-intake.md), [urolithin A as a bounded mitophagy supplement experiment](urolithin-mitophagy.md), [GlyNAC as a glutathione-linked supplement claim](glynac.md), [spermidine as an autophagy-adjacent supplement claim](spermidine-supplementation.md), [taurine as a contested healthy-aging signal](taurine-healthy-aging.md), [advanced glycation chemistry](glycation-end-products.md), [creatine as a training adjunct](creatine-monohydrate.md), and [Stack Creep](stack-creep.md). The section's practical question is not which diet identity sounds best, but which food-timing, food-quality, supplement, and macronutrient decisions improve measurable risk without creating a larger problem.

Read straight through, or land on a specific entry and follow its outgoing links into the rest of the book.
