How are MY FOODBOOK and Allergie related?

The provided context does not directly link 'MY FOODBOOK' and 'Allergie'. MY FOODBOOK likely refers to a food-related product or service, while Allergie means allergy. DNA tests (like those from MyBody-X) can identify genetic tendencies for food intolerances (e.g., lactose intolerance), but these are not allergies. The evidence for such genetic associations is moderate (observational/GWAS) and not diagnostic. Without explicit context, the relationship is unclear. For true allergies, medical evaluation is necessary.
