Evidence check: Omega-3 Index in the context of Langlebigkeit

MyBody-X DNA tests can identify common variants related to caffeine and alcohol metabolism, such as CYP1A2 (caffeine) or ADH1B/ALDH2 (alcohol). However, the effect sizes are generally modest, and the results are not suitable as clinical directives. A systematic review (PMC12628764) indicates that SNP effects on nutrient metabolism are small. The test can give you a rough idea whether you metabolize caffeine faster or slower, but it does not replace medical advice. For whether you should avoid certain foods or drugs, the evidence is weak. In particular, direct-to-consumer tests are not sufficiently validated for drug interactions. A positive finding for alcohol intolerance (e.g., ADH1B) does not mean you can never drink alcohol – environmental and lifestyle factors are equally important. Caveat: Never change your medication or diet based solely on genetic test results. Consult a doctor or dietitian for specific questions. The evidence is rated as 'human-moderate' because while studies exist for the gene variants, their real-world applicability is limited.
