The Nurses' Health Study of 100,000 women shows that moderate drinking is associated with a lower risk of type 2 diabetes in middle-aged women.

At the beginning of the study, none of the women reported that they had diabetes. Ten years later, 935 had developed diabetes. Those taking one drink a day were 58 percent less likely to develop diabetes. Those taking two drinks a day were 250 percent less likely to develop diabetes. Those taking more than two drinks a day had a marked increase in diabetes. So moderate drinking was associated with decreased risk for diabetes, while heavy drinking increased risk. However, moderate drinkers may have more healthful diets than heavy drinkers, so this study has not proven a direct relationship between alcohol consumption and diabetes. Prevention or control of diabetes probably has more to do with the diet people eat than the alcohol they drink. See report #D222.
