Common mistakes around DNA Test Ernährung

Common mistakes around DNA tests for nutrition include overinterpreting single gene variants and expecting a perfect diet prescription. In reality, most genetic effects are small, many genes interact, and lifestyle factors like exercise, sleep, and stress dominate. Tests like NutriCare offer 'inspiration' rather than medical advice – that's marketing, not evidence-based medicine. Another mistake: using IgG tests as food intolerance tests. They reflect exposure, not intolerance, and unnecessary restrictions can harm nutrition. A borderline TSH from a home test does not diagnose slow metabolism; a full thyroid panel by a doctor is required. Even well-studied genes like FTO and MC4R explain only a small fraction of weight variation. The evidence is mixed: some associations are supported by GWAS, but clinical utility is limited. Bottom line: DNA tests can provide hints, but they cannot replace a balanced diet, physical activity, and professional medical guidance.
