Myths vs facts: DNA Stoffwechselanalyse | inkl. 28-Tage-Plan & Rezeptbuch and Wechseljahre

The DNA metabolism test is often marketed as a key to personalized nutrition, including a 28-day plan and recipe book. Fact: Some genetic variants do have evidence-based links to metabolism. For example, the FUT2 secretor variant shows a moderate association with vitamin B12 levels (GWAS evidence). ADH1B variants affect alcohol metabolism (human-moderate evidence). TAS2R38 (bitter taste) can indirectly influence vegetable intake (GWAS). rs7903146 (TCF7L2) is a moderate risk factor for type 2 diabetes (GWAS). Myth: These tests do not provide a direct diagnosis or a scientifically validated personalized diet for the general population. The evidence is mostly GWAS-based, not clinically confirmed. The 28-day plan and recipe book are marketing tools, not evidence-based. For menopause: DNA tests can offer hints about nutrient needs (e.g., vitamin D, calcium, B12), but they do not replace medical care. Hormonal changes during menopause are complex and not captured by DNA alone. Caveat: Not diagnostic, not medical advice. Evidence grade: mixed (GWAS, mechanistic, some marketing).
