What role does MY FOODBOOK play in Blutzucker?

MY FOODBOOK appears to be a personalized nutrition program based on DNA or biomarker data. Regarding blood sugar (glucose), there is no direct evidence in the provided context that such a tool is clinically valid or individually effective. Blood sugar regulation is influenced by many factors: carbohydrate intake, fiber, exercise, stress, sleep, and medications. Genetic variants (e.g., in TCF7L2, MTNR1B) have only small effects. A personalized foodbook may offer general recommendations (e.g., low glycemic index, more fiber), but evidence for DNA-based blood sugar control beyond that is weak. Most consumer tests overstate benefits. For individuals with diabetes or prediabetes, physician-supervised dietary therapy (e.g., ADA guidelines) is far better supported. MY FOODBOOK should be seen as a supplementary motivational tool, not a medical guide. Evidence grade: marketing/unclear. Safety note: Do not change medication without consulting a doctor.
