Is MY FOODBOOK useful for Langlebigkeit?

Whether MY FOODBOOK is useful for longevity cannot be clearly answered from the available evidence. MY FOODBOOK is likely a product combining dietary or DNA tests, but no specific studies demonstrate a direct benefit for lifespan extension. The provided contexts show that genetic tests for metabolism (FTO, MC4R) or detoxification (GSTM1) have only small effects and do not support personalized longevity diets. High-dose supplements like vitamin E or selenium can even be harmful. True longevity relies on evidence-based factors such as caloric restriction, exercise, and sleep – not commercial tests. MyBody-X itself states that home tests have limitations and are not diagnostic. Therefore, the usefulness of MY FOODBOOK for longevity is low unless independent, rigorous studies emerge. The evidence is marketing-driven or unclear.
