These recommendations must also fit with what we know about diet and other diseases like heart disease. Maintain a desirable weight. Eat a variety of foods. Cut down on total fat intake. Eat more high fiber foods.
Fiber comes from plant foods only, and includes breads, cereals, legumes, fruits, and vegetables.
Choose whole grain breads and crackers. Include at least two, and ideally five or more, servings of fruits and vegetables a day and at least three to four servings of cruciferous vegetables per week. Examples of cruciferous vegetables include broccoli, brussel sprouts, cabbage, cauliflower, and turnip greens. Trim the fat from the meat you eat. Choose fish or chicken at other meals, and try to have a meatless meal once a week.
