Going With Healthy Fat

Eating omega-3 fatty acids from fish and plant sources can protect your heart. These healthful fats make blood less likely to form clots that cause heart attacks, and they protect against irregular heartbeats that cause sudden cardiac death, says the American Heart Association in a 2002 study. Food sources include mackerel, lake trout, herring, sardines, albacore tuna, salmon, tofu, soybeans, canola, walnuts and flaxseeds.
