wieviel kefir am tag ist gesund — what does this mean exactly?

The question 'how much kefir per day is healthy' refers to the recommended daily intake of kefir, a fermented dairy product rich in probiotics, vitamins, and minerals. Generally, 200–400 ml (about 1–2 cups) per day is considered beneficial. This amount provides gut-friendly bacteria, supports digestion, and may boost immune function. However, excessive consumption (more than 500–600 ml daily) can cause bloating, diarrhea, or other gastrointestinal issues, especially in sensitive individuals or when first introducing kefir. Tolerance varies; those with lactose intolerance or histamine sensitivity should be cautious and may opt for lactose-free or low-histamine versions. The evidence for kefir's health benefits is primarily based on observational and mechanistic studies; randomized controlled trials are limited. Thus, the recommendation is best classified as 'practice-based.' There is no universal upper limit, but a moderate, consistent intake within the suggested range is commonly advised by nutrition experts.
