35 Heart-Healthy Superfoods

Potatoes are rich in vitamin C and fiber—both can protect the heart. When they are cooked and then cooled (as in potato salad) they contain high amounts of a special fiber called resistant starch, which increases fullness and can help lower heart disease risk by keeping blood sugar and insulin levels stable. Nab more nutrients by leaving the skins on—and mix low-fat mayo and low-fat yogurt for a healthier, calcium-rich dressing.
