wie gesund ist kefir — what does this mean exactly?

Kefir is a fermented milk drink rich in probiotics, vitamins, and minerals. Studies suggest benefits for gut health, immune function, and possibly cholesterol levels. However, much of the evidence comes from small or mechanistic studies, not large randomized controlled trials. Individual effects vary. For most people, kefir is safe and can be part of a balanced diet, but it is not a miracle food. Those with lactose intolerance or histamine sensitivity should be cautious. The provided context does not contain specific evidence on kefir, so the overall evidence base remains general and unclear.
