wie trinkt man kefir am besten — can a DNA test help?

The best way to drink kefir depends on personal tolerance and taste, not genetics. Kefir is a fermented milk drink rich in probiotics. General advice: start with small amounts (e.g., 50 ml daily), choose plain unsweetened varieties, and if lactose intolerant, opt for lactose-free or longer-fermented kefir. Can a DNA test help? Only indirectly: genes like LCT (lactase persistence) or TAS2R38 (bitter taste) might influence preference or tolerance, but the provided context lacks validated studies linking DNA to kefir optimization. Evidence is best described as 'unclear' or 'marketing' if companies claim otherwise. In practice, your own digestive response is more reliable than a genetic test. For gut health concerns, a microbiome stool test may offer more actionable insights than DNA.
