New research about the heart healthy effects of drinking shows it's not how much, but how often you drink that matters.
The Harvard study followed 38,000 men for 12 years and found a 30% lower rate of heart attack in men who drank moderately three to seven nights a week compared to non-drinkers. They say it didn't matter what kind of alcohol they drank, but frequency was the key. The protective benefit comes in part from alcohol's boosting effect on HDL or good cholesterol levels and potential benefits on insulin sensitivity and clotting function.
By the way, the experts stressed moderate drinking and agreed that excess drinking poses an endless list of health problems.
