wie trinkt man kefir — which blood markers matter?

The provided context does not directly address kefir consumption or specific blood markers. Generally, kefir is a fermented dairy product rich in probiotics that may influence blood markers such as LDL and HDL cholesterol, triglycerides, fasting glucose, HbA1c, inflammatory markers like hs-CRP, and liver enzymes. Individual responses vary based on gut microbiota, genetic factors (e.g., lactase persistence variant rs4988235 mentioned in the context, and PCSK9 gene variants affecting LDL regulation). However, no direct evidence from the context links kefir to these markers. Practical advice: start with small amounts (e.g., 100 ml) of plain kefir, increase gradually. Caution for lactose intolerance or histamine sensitivity. Blood marker monitoring should be done under medical supervision, not solely based on kefir intake. Evidence: unclear, as the context lacks specific studies on kefir and blood markers.
