Is ADH1B useful for Langlebigkeit?

ADH1B is not directly a 'longevity gene' but can influence health indirectly through alcohol metabolism. Variants like ADH1B*2 (rs1229984) are associated with lower alcohol consumption and reduced risk of alcohol-related diseases (e.g., liver cirrhosis, certain cancers). Some observational studies link these variants to lower all-cause mortality, but the effect is modest and context-dependent. The evidence is human-observational, not from interventional longevity trials. Consumer DNA tests may report ADH1B status, but the clinical utility for longevity optimization is limited. Lifestyle factors (diet, exercise, sleep) have far stronger evidence. Therefore, ADH1B is not a robust actionable target for longevity. Evidence grade: human-observational. Caveat: Do not use alone for health decisions.
