What role does ADH1B play in Blutzucker?

ADH1B (alcohol dehydrogenase 1B) primarily metabolizes ethanol. Some studies suggest an indirect link to blood sugar: carriers of the fast-metabolizing ADH1B*2 variant (common in East Asians) often show lower fasting glucose after alcohol consumption, possibly due to altered insulin sensitivity or reduced caloric intake from alcohol. However, the evidence is mostly mechanistic or from GWAS with small effect sizes. No RCTs demonstrate a direct causal effect of ADH1B on blood sugar regulation independent of alcohol. In practice, ADH1B genotypes may contribute to individual risk profiles for type 2 diabetes, but they are not a standalone biomarker for blood glucose. MyBody-X DNA tests analyze ADH1B in the context of alcohol metabolism, not as a direct blood sugar marker. Relying solely on this gene for blood sugar management is not evidence-based.
