Alcohol linked to insulin sensitivity, resulting in higher HDL-cholesterol levels
Compared to heavy drinking or abstinence moderate consumption has been associated with lower mortality rates according to a study by Van de Wiel in The Netherlands Journal of Medicine. Van de Wiel asserts that half of the protective effect of alcohol on cardiovascular risk can be explained by its ability to raise HDL-cholesterol (good cholesterol). Since light to moderate alcohol intake is associated with enhanced insulin sensitivity and this improvement in sensitivity results in higher HDL cholesterol levels, it is suggested that this is one of the routes taken by alcohol to act upon HDL metabolism. HDL cholesterol and insulin sensitivity increases are also considered to have a beneficial effect on the process of antherosclerosis.
