What to watch with NutriCare | INFINITY DNA-Test and Langlebigkeit?

The NutriCare and INFINITY DNA tests from MyBody-X claim to provide personalized nutrition and longevity recommendations based on genetic variants. However, the scientific evidence for many of the tested SNPs (e.g., in VDR, FADS2, CLOCK) is weak to moderate. Most associations come from GWAS or mechanistic studies, not from randomized intervention trials that clearly demonstrate a benefit for lifespan. Effect sizes are often small and overshadowed by lifestyle factors (diet, exercise, sleep). For example, the VDR SNP rs2228570 is linked to vitamin D metabolism, but personalized dosing based solely on this marker is not evidence-based – a blood measurement is more reliable. The ALDH2 variant (alcohol flush reaction) is relevant, but the recommendation to avoid alcohol entirely applies only to homozygotes. Be aware that test results do not replace clinical diagnosis and that marketing claims are often exaggerated. For true longevity, sustainable lifestyle habits are key, not single gene variants. Consult a physician or dietitian before making drastic changes.
