The question about preparing 'Kefir Männer' is ambiguous – possibly a typo or a specific product. If you mean how to make kefir (fermented milk drink) for men: traditional kefir is made by fermenting milk with kefir grains (starter culture) at room temperature (20–25 °C) for 24–48 hours. No special adjustments are needed for men; kefir is generally beneficial due to probiotics, vitamins, and minerals. For sensitive digestion, start slowly (e.g., 50 ml daily). The provided context contains no specific information on kefir. Evidence for kefir's health benefits is mostly mechanistic and from observational studies; robust RCTs in men are lacking. Caution for lactose intolerance: kefir has less lactose than milk but not zero. If 'Kefir Männer' refers to a branded product or specific culture, follow manufacturer instructions. Without further details, this answer remains conservative.
