MyBody-X angle on Longevity Ernährung

MyBody-X offers DNA and microbiome tests often marketed for longevity nutrition, but the evidence base is limited. Genetic variants like FOXO3 are associated with longevity in GWAS, but individual effect sizes are tiny—lifestyle and diet dominate. Microbiome-derived short-chain fatty acids (SCFAs) like butyrate show promise for gut health and metabolism, but clinical reference ranges are lacking; production depends heavily on fiber intake. Supplements like NMN for NAD+ boosting have preclinical data but no human RCTs for lifespan extension. MyBody-X tests may provide rough hints but do not replace evidence-based dietary advice. A high-fiber, plant-based diet with moderate caloric restriction remains the most robust approach. Beware of exaggerated marketing: these tests are research-grade, not diagnostic.
