Healthy carbohydrates.

During digestion, sugars (simple carbohydrates) and starches (complex carbohydrates) break down into blood glucose. Focus on the healthiest carbohydrates, such as fruits, vegetables, whole grains, legumes (beans, peas and lentils) and low-fat dairy products.

Fiber-rich foods.

Dietary fiber includes all parts of plant foods that your body can't digest or absorb. Fiber can decrease the risk of heart disease and help control blood sugar levels. Foods high in fiber include vegetables, fruits, nuts, legumes (beans, peas and lentils), whole-wheat flour and wheat bran.

Heart-healthy fish.

Eat heart-healthy fish at least twice a week. Fish can be a good alternative to high-fat meats. Cod, tuna and halibut, for example, have less total fat, saturated fat and cholesterol than do meat and poultry. Fish such as salmon, mackerel and herring are rich in omega-3 fatty acids, which promote heart health by lowering blood fats called triglycerides. However, avoid fried fish and fish with high levels of mercury, such as tilefish, swordfish and king mackerel.

Good' fats.
Foods containing monounsaturated and polyunsaturated fats — such as avocados, almonds, pecans, walnuts, olives, and canola, olive and peanut oils — can help lower your cholesterol levels. Eat them sparingly, however, as all fats are high in calories.
