What to watch with Kefir Darm and Langlebigkeit?

Kefir is a fermented dairy product rich in probiotics (bacteria and yeasts) that can support gut health. A healthy gut microbiome is associated with reduced inflammation and may contribute to longevity, but direct evidence linking kefir to increased lifespan in humans is limited. Genetic variants (e.g., in FTO, GHRL, or TCF7L2) can influence metabolism and appetite, but they do not determine whether kefir is beneficial for you. DNA tests can offer insights, but they should not be the sole basis for dietary decisions. Focus on a balanced diet high in fiber, low in sugar, and regular physical activity. If you have lactose intolerance, choose lactose-free kefir or plant-based alternatives. Consult a healthcare professional for personalized advice.
