How to prepare for Kefir Basis

The question about preparing for a kefir basis is outside the provided knowledge contexts, which focus on DNA tests and nutrigenetics. For kefir preparation, general best practices include: use fresh milk (cow, goat, or plant-based) and a quality starter culture (kefir grains or powder). Ensure clean utensils and a stable temperature (20–25°C) during fermentation (24–48 hours). Avoid metal containers as they may affect the cultures. For lactose-intolerant individuals, kefir is often tolerated due to low lactose content, but start with small amounts. Evidence for health benefits (e.g., gut health) is based on observational studies and is not conclusive. Consult a healthcare professional for personalized advice.
