ist bier gesund für den darm — which blood markers matter?

Whether beer is healthy for the gut is not straightforward. Beer contains polyphenols and soluble fiber that can act as prebiotics and support gut microbiota. However, alcohol damages the intestinal lining, increases permeability (leaky gut), and promotes inflammation. Evidence is mixed: moderate intake (e.g., one beer) may show some benefits in microbiome studies, but regular consumption raises the risk of gut disorders regardless of amount. Which blood markers matter? Liver enzymes (GGT, ALT, AST) rise with excessive intake. Inflammatory markers like hs-CRP may increase. Homocysteine can be affected by alcohol. There is no direct blood marker for gut health; zonulin (gut permeability) is not a routine test. Bottom line: beer is not a health drink. For gut health, prefer non-alcoholic options and monitor liver and inflammatory markers in blood work.
