Drinking alcohol does not necessarily increase your risk for heart disease, as long as it is done in moderation. However, drinking too much alcohol can lead to high blood pressure and obesity, as well as a whole host of health problems.
Drinking in moderation is defined as one drink per day for women and two drinks per day for men. Limiting yourself to that average may help you lower your odds of heart trouble. As a bonus, it reduces your stroke risk, too.
