What to watch with MY FOODBOOK and Darmgesundheit?

Combining MY FOODBOOK (DNA-based dietary advice) with the gut health test (microbiome analysis) sounds promising, but the scientific foundation is limited. MY FOODBOOK uses common SNPs (e.g., FTO, APOA5) with small effect sizes – evidence is mostly marketing-driven or derived from GWAS, not from randomized weight-loss trials. The gut test shows bacterial ratios like Akkermansia, but clear actionable guidance is lacking: low Akkermansia is not a proven disease marker, and targeted probiotics to raise it are insufficiently supported. Watch out that neither test provides medical diagnoses. A sensible approach is to use the results as general orientation for a balanced diet – e.g., more fiber if diversity is low – but not as the sole basis for supplements or strict diets. Consult a registered dietitian or physician before making major changes.
