What to watch with MY FOODBOOK and gut health?

MY FOODBOOK from MyBody-X combines results from DNA analysis, gut microbiome testing, and metabolism markers to provide personalized dietary recommendations. Regarding gut health, the microbiome test measures bacterial composition and diversity, but a 'healthy' microbiome is not scientifically well-defined. Reference ranges are based on a general population, not clinical endpoints. Additionally, IgG food sensitivity tests are often included – these are controversial and not clinically validated for diagnosing intolerances. DNA-based advice relies on SNPs with mostly small effect sizes. Key watch-outs: MY FOODBOOK is not a medical device, does not replace professional medical advice, and should not be used to treat diseases. For persistent digestive issues or in children, consult a doctor first. The evidence for tangible gut health improvements from such combo tests is currently weak to moderate; many claims are marketing-driven. Use the results as exploratory insights, not as definitive prescriptions.
