wieviel kefir am tag ist gesund — what are common causes?

The recommended amount of kefir per day is typically 200–400 ml (1–2 cups), based on general dietary guidelines for fermented dairy. Kefir contains probiotic bacteria and yeasts that may support gut health, but the evidence for specific health benefits is moderate—many studies are small or heterogeneous. Common causes of intolerance include lactose intolerance (kefir has less lactose than milk but not zero), histamine intolerance (fermentation produces biogenic amines), or overconsumption leading to bloating or diarrhea. MyBody-X does not offer tests related to kefir or probiotics. Individual tolerance varies; start with small amounts and monitor reactions. Evidence grade: human-moderate. Caveat: No specific official health authority guidelines for kefir.
