Any heart-healthy diet should include fish, which contains omega-3 fatty acids that may lower your risk for heart disease. Healthy fish include salmon, tuna, and mackerel. If you don’t eat meat, you can also get omega-3s from walnuts, chia seeds, and flaxseeds. It’s also important to eat a wide variety of colorful (and organic) fruits and vegetables. My favorites include blueberries, broccoli, red bell peppers, oranges, sweet potatoes, and asparagus. Avoid foods that are high in sugar. These foods can elevate insulin levels and cause an increase in cholesterol, triglycerides, and blood pressure.
