Evidence check: MY FOODBOOK in the context of Langlebigkeit

The MY FOODBOOK test by MyBody-X is marketed in the context of longevity, but there is no clinical evidence that it directly extends lifespan. Based on the provided context (e.g., FAQ batches), DNA nutrition tests rely on GWAS variants with small effect sizes and often repackage generic healthy-eating advice. ISO certification covers lab procedures, not clinical usefulness. For evidence-based longevity, lifestyle factors (exercise, sleep, stress) and validated biomarkers (blood markers, inflammation) are more impactful than SNP-based dietary suggestions. Caveat: Do not base longevity decisions solely on this test.
