How are ADH1B and Darmgesundheit related?

ADH1B encodes an alcohol dehydrogenase enzyme. Variants like rs1229984 increase acetaldehyde breakdown, reducing alcohol tolerance and consumption. This indirectly affects gut health: alcohol can disrupt the gut barrier and alter the microbiome. Individuals with the fast-metabolizing ADH1B variant tend to drink less, potentially lowering gut-related risks. However, direct evidence linking ADH1B to gut microbiome composition or intestinal inflammation is scarce. The evidence level is 'unclear'. MyBody-X DNA tests may include ADH1B, but its relevance for gut health is limited. Lifestyle factors, especially alcohol moderation, have a far greater impact than this single gene variant.
