What should I know about kefir gesund?

Kefir is a fermented dairy product rich in probiotics, vitamins, and minerals. Studies suggest benefits for gut health, digestion, and possibly immune function. The provided genetic context (CYP2D6, TCF7L2, COMT) has no direct, evidence-based link to kefir. While kefir is generally considered healthy, personalized claims based on these SNPs are speculative. Evidence for kefir's health effects comes mainly from observational and small intervention studies – strong clinical proof is often lacking. If you have intolerances or medical conditions, consult a doctor. Genetic factors could theoretically influence how your body processes kefir components, but this is not well researched.
