Is MY FOODBOOK useful for Darmgesundheit?

Whether MY FOODBOOK is useful for gut health cannot be confirmed with strong evidence. No specific studies or clinical data directly support its benefit for gut health. In general, DNA-based nutrition tests (often included in such products) have weak scientific backing: individual genetic variants have very small effects on diet response, and no RCTs show that DNA-guided diets outperform standard advice. Home food intolerance tests are also often unreliable and cannot replace medical diagnosis. MY FOODBOOK may serve as a structured food diary to help identify personal eating patterns, but for improving gut health specifically, the evidence is lacking. Claims are likely marketing-driven. Caveat: For serious gut issues, consult a doctor or gastroenterologist.
