A recent study found that moderate drinking may be associated with a reduced risk of heart attack in healthy men. The research, conducted on 8,867 healthy men, suggests that even light drinkers have a lower risk than those who do not drink at all. Moderate drinking was linked to increased levels of HDL or 'good' cholesterol in the blood.
