Evidence check: MY FOODBOOK in the context of Darmgesundheit

The evidence for 'MY FOODBOOK' in the context of gut health is weak and based on general principles of nutrigenetics and microbiome testing. The MyBody-X DNA nutrition test analyzes genetic variants linked to nutrient metabolism, but most data come from GWAS with small effect sizes. The microbiome test for children (as an analogy) lacks validated reference ranges and is rated as 'practice-based'. There are no specific clinical studies on 'MY FOODBOOK' for gut health. Combining DNA and microbiome data could theoretically offer personalized dietary advice, but evidence for clinical relevance is lacking. Consumers should be aware that such tests do not replace medical diagnosis and results should not be taken as definitive dietary prescriptions. Safety note: For serious gut issues, medical consultation is required.
