ist bier gut für die verdauung — which blood markers matter?

The idea that beer is good for digestion is a common belief, often linked to hops' bitter compounds and potential prebiotic effects. However, the scientific evidence is weak and mixed. Alcohol is known to damage the gut lining, disrupt the microbiome, and promote inflammation. Non-alcoholic beer may offer some polyphenols and fiber, but any benefit is modest and not a justification for regular consumption. Which blood markers matter? Liver enzymes (GGT, ALT, AST) are key – they rise with regular alcohol intake and indicate liver stress. Inflammatory markers like CRP can also increase. Markers of gut permeability (e.g., zonulin) or intestinal inflammation (e.g., calprotectin) are rarely measured in standard blood tests and are not part of typical consumer health panels. MyBody-X's Magen-Darm test analyzes stool for microbiome composition, not blood markers. Its results are educational, not diagnostic. In summary: beer is not recommended for digestive health; blood markers like GGT and CRP can reflect alcohol's systemic effects, but they do not directly assess gut function. For persistent digestive issues, consult a healthcare provider.
