ist kefir gut für den darm — what can you do yourself?

Kefir can support gut health due to its content of probiotic bacteria and yeasts. Studies suggest positive effects on gut microbiota composition, digestion, and possibly inflammation. However, evidence is mixed: kefir composition varies widely (milk vs. water kefir, fermentation time, strains). What you can do yourself: incorporate kefir regularly, ideally homemade from kefir grains to avoid additives. Monitor tolerance – histamine intolerance or lactose sensitivity may cause issues. A DNA test for gut health is not necessary; kefir's effects are general, not personalized. Evidence: human-moderate (observational studies, small RCTs).
