A healthy diet is one of the best weapons you have to fight cardiovascular disease. The food you eat (and the amount) can affect other controllable risk factors: cholesterol, blood pressure, diabetes and overweight. Choose nutrient-rich foods which have vitamins, minerals, fiber and other nutrients but are lower in calories over nutrient-poor foods. Choose a diet that emphasizes intake of vegetables, fruits, and whole grains; includes low-fat dairy products, poultry, fish, legumes, nontropical vegetable oils, and nuts; and limits intake of sweets, sugar-sweetened beverages, and red meats. And to maintain a healthy weight, coordinate your diet with your physical activity level so you're using up as many calories as you take in.
