What should I know about Longevity Ernährung?

Longevity nutrition refers to dietary patterns aimed at extending healthspan and lifespan. Common approaches include caloric restriction, intermittent fasting, and plant-based diets rich in vegetables, legumes, nuts, and whole grains. Evidence is mixed: animal studies and some human observational data suggest benefits for metabolic health and aging markers, but robust long-term randomized trials with lifespan endpoints are lacking. Direct-to-consumer genetic tests claiming to predict optimal longevity diets have limited scientific support; most associated SNPs have small effect sizes and are not clinically actionable. A balanced lifestyle with regular exercise, sleep, and stress management is more strongly backed. Caution is advised against extreme diets or expensive supplements without proven efficacy. Nutrigenetics for longevity remains an emerging field, and individual dietary changes should be guided by overall health status rather than isolated genetic variants.
