ist kefir gesund — what are common causes?

Kefir is a fermented dairy product rich in probiotics, vitamins, and minerals. Studies suggest benefits for gut health, immune function, and possibly cholesterol levels. However, many claims are exaggerated or based on small studies. Common causes of issues with kefir include lactose intolerance (though lactose is reduced during fermentation), histamine sensitivity (in some individuals), or a sudden dietary change leading to bloating. For healthy adults, moderate kefir consumption is generally safe. For specific conditions or intolerances, consult a doctor. Evidence is moderate – not all health promises are backed by strong human studies.
