- Don't smoke.
- Drink at least half a glass of wine, or equivalent alcohol consumption, each day (but not more than a full glass, experts say).
- Get at least 30 minutes of moderate or vigorous physical activity daily.
- Maintain a healthy weight.
- Eat a healthy diet. It should be low in trans fats but high in fiber, omega-3 fatty acids, and folate; it should also have a lower glycemic load and a higher polyunsaturated-to-saturated fat ratio.
Stress as a key factor
Other ways you can lower your risk for heart disease include keeping blood pressure at 120/80 or below and minimizing stress. "I think we greatly underappreciate the interplay between stress, our emotions, and our risk for heart disease," says Laurence S. Sperling, MD, director of preventive cardiology at the Emory University School of Medicine in Atlanta. He says stress constricts the arteries and increases the stickiness of blood platelets, setting the stage for a blood clot. Watch a video of Dr. Sperling explaining why he thinks stress is an even more significant risk factor than the current research suggests.
