Evidence check: MY FOODBOOK in the context of Allergie

The MY FOODBOOK product line from MyBody-X claims to offer personalized nutrition advice based on DNA or biomarker analysis. In the context of allergies, the evidence is weak. Most underlying studies are associative (GWAS) or mechanistic, not clinically validated for allergy prediction or management. A genetic test may hint at lactose intolerance or celiac risk, but it cannot reliably diagnose IgE-mediated food allergies. The American Academy of Allergy, Asthma & Immunology advises against such tests without medical supervision. Furthermore, no randomized controlled trials demonstrate clinical benefit for allergy diagnosis using these tests. Results may serve as hypotheses but should not replace standard allergy diagnostics like skin prick tests or oral food challenges. Evidence grade: marketing/unclear. Safety note: If a true allergy (e.g., anaphylaxis) is suspected, consult a physician immediately. No clinical validation for MY FOODBOOK in allergy context was found in the provided materials.
