wann kefir am besten trinken — which blood markers matter?

The question about the best time to drink kefir and which blood markers matter cannot be directly answered from the provided context. Generally, kefir as a fermented dairy product may support gut health due to its probiotic content, which could indirectly influence inflammatory markers (e.g., CRP) and glucose metabolism. Studies show moderate effects on blood lipids (total cholesterol, LDL) and fasting glucose, but results are heterogeneous. The timing of consumption (morning vs. evening) lacks strong evidence; some suggest morning on an empty stomach for better probiotic survival, others post-meal for blood sugar regulation. Relevant blood markers include: fasting glucose, HbA1c, lipid profile (triglycerides, HDL, LDL), hs-CRP, and possibly liver enzymes (ALT, AST). A DNA test for lactose intolerance (e.g., MCM6 variants) may be relevant since kefir contains lactose. Evidence is moderate – kefir is a food, not a drug, and individual responses vary. For metabolic conditions, consult a physician.
