Myths vs facts: MY FOODBOOK and longevity

The idea that a personalized food book („MY FOODBOOK“) alone can significantly extend lifespan is a myth. The fact is: MyBody-X's Analyse Booklet compiles DNA and biomarker results based on nutrigenetics and functional medicine principles. Such recommendations can help address individual weak points (e.g., vitamin D or magnesium needs) and thereby support healthspan. However, longevity is multifactorial – it depends on diet, exercise, sleep, stress management, social connections, and environment. Evidence for a direct extension of maximum lifespan through personalized nutrition is weak; most studies show moderate effects on risk markers, not on life expectancy itself. Moreover, many recommendations are based on mechanistic or practice data, not large randomized trials. The booklet is a useful awareness tool, but not a substitute for medical care. Users should understand its limits: genetic effect sizes are often small, and implementation requires discipline. In summary: MY FOODBOOK can be part of a healthy lifestyle, but it is no 'longevity miracle'.
