What should I know about welche diat passt zu mir?

The question 'Which diet suits me?' is often answered with DNA-based tests, but the scientific evidence is weak to moderate. Some genetic variants like MTHFR A1298C (folate metabolism), FUT2 rs601338 (vitamin B12 absorption), or APOE4 (lipid metabolism) have a detectable but small impact on nutrient needs. However, large randomized trials are lacking to show that a personalized diet based solely on these genes outperforms general healthy eating. Many commercial tests exaggerate effects and mix marketing with science. Moreover, risk variants like rs2395182 (celiac) are not diagnostic – a gluten-free diet should only follow medical confirmation. Skin DNA tests for collagen or glycation also lack clinical evidence. My advice: use genetic information as a curious hint, not a diet plan. Consult a doctor for specific risks (e.g., APOE4) and rely on proven dietary principles: plenty of vegetables, whole grains, healthy fats, low sugar. The evidence for a 'gene diet' remains mostly in the realm of marketing and mechanistic hypotheses.
