— such as nausea, headache…eir outcomes, as they usually lead a healthier than average lifestyle, and don’t smoke or eat meat. There is, however, a gene variant that is associated with lighter drinking that has been helpful in alcohol research. People who inherit a certain genetic variant of the enzyme that breaks down alcohol tend to drink less because they feel alcohol’s unpleasant side effects — such as nausea, headache and flushing — more readily. This, in effect, randomizes society by genes, and not by socioeconomic influences.
