Each of the alcohol-containing diets improved lipid profiles by reducing low- density lipoprotein (LDL) cholesterol and triacylglycerol levels, whereas the 2-drink diet increased high-density lipoprotein (HD) cholesterol levels. Women who began the study with the highest serum concentrations of LDL-cholesterol and triacylglycerols showed the greatest benefit. Considering the magnitude of lipid changes observed in the study, the authors project that consumption of 1 alcoholic drink per day could decrease CVD risk in postmenopausal women by 4-5%, and consuming 2 drinks per day could result in a 10-13% decrease in CVD risk.
