Eating a healthy diet can reduce your risk of heart disease. Two examples of heart-healthy food plans include the Dietary Approaches to Stop Hypertension (DASH) eating plan and the Mediterranean diet.

A diet rich in fruits, vegetables and whole grains can help protect your heart. Beans, other low-fat sources of protein and certain types of fish also can reduce your risk of heart disease.

Limiting certain fats you eat also is important. Of the types of fat — saturated, polyunsaturated, monounsaturated and trans fat — saturated fat and trans fat are the ones to try to limit or avoid. 

"Cholesterol is a fatty substance produced naturally by your body (blood cholesterol). You can also get cholesterol from some foods (dietary cholesterol). It is used for many different things in your body, but is a problem when there’s too much of it in your blood."

Heart-healthy eating isn't all about cutting back, though. Healthy fats from plant-based sources, such as avocado, nuts, olives and olive oil, help your heart by lowering the bad type of cholesterol.

Eating several servings a week of certain fish, such as salmon and mackerel, may decrease your risk of heart attack.

For healthy adults, that means up to one drink a day for women of all ages and men older than age 65, and up to two drinks a day for men age 65 and younger. At that moderate level, alcohol can have a protective effect on your heart. More than that becomes a health hazard.
