ist bier gut für den darm — can a microbiome test help?

Whether beer is good for your gut is not a simple yes or no. On one hand, beer contains polyphenols and fibers from barley and hops that can act as prebiotics, potentially promoting beneficial gut bacteria, especially in dark or craft beers. On the other hand, alcohol itself damages the gut lining, disrupts the intestinal barrier, and can promote inflammation – even in moderate amounts. A microbiome test can show you the diversity of your gut flora and whether certain beneficial strains are low. However, it cannot predict how your unique microbiome will respond to beer. The evidence is mixed: there are mechanistic studies on polyphenols, but no strong clinical trials showing a net health benefit from beer. For gut health, non-alcoholic beer or other prebiotic foods are safer choices. A microbiome test can provide general insights but should not replace professional medical advice.
