In an analysis of pairs of twins with different alcohol habits,
those with moderate levels of alcohol consumption had half the
risk of diabetes compared with those with low levels of alcohol
consumption. The researchers say these results are in line with
a number of previous studies that have shown that moderate alcohol
consumers have a 30-to-40 percent reduced risk of type 2 diabetes.
The investigators also saw that levels of alcohol consumption
of 20 g/day or more appeared to increase the likelihood of diabetes
for lean women, but not for overweight women or men. Also, binge
drinking increased the number of diabetes cases among women.
