What to watch with MY FOODBOOK and longevity?

MY FOODBOOK is a personalized food diary based on DNA and biomarker data. For longevity, watch out for the following: The evidence behind many dietary recommendations from genetic tests is weak – mostly mechanistic or from GWAS, not from long-term randomized trials. The results can help you spot patterns (e.g., response to carbs or fats), but they do not replace medical advice. Be aware that the app does not diagnose conditions, and lifestyle factors (sleep, exercise, stress) have a much larger impact on longevity than single gene variants. MyBody-X's test validation is not fully public; be cautious of overblown claims. Use MY FOODBOOK as a self-tracking tool, not a medical device.
