wieviel kefir am tag ist gesund — can a microbiome test help?

A common recommendation for daily kefir consumption is 100–200 ml (about one small glass). Kefir is a fermented dairy product rich in probiotic bacteria and yeasts. Studies suggest regular intake may positively influence gut microbiota, support digestion, and modulate immune function. However, there is no one-size-fits-all dose; individual tolerance varies. People with lactose intolerance often tolerate kefir better than milk because fermentation reduces lactose content. Those with histamine intolerance may experience adverse reactions. A microbiome test (e.g., from MyBody-X) can analyze gut bacterial composition and offer insights into whether kefir might benefit your personal gut health. However, the evidence for such tests is still emerging: they provide a snapshot of current microbiota but do not establish causation for health outcomes. The general recommendation is based on traditional use and moderate scientific evidence. Start with small amounts and monitor your response. If you have concerns or symptoms, consult a healthcare professional or dietitian.
