Include high fiber cereals, such as oatmeal, granola or wheat flakes. For a snack, try whole grain crackers or whole-wheat bagels. The next levels up are fruits and vegetables. Try to incorporate fruit or juice with your breakfast or snacks. Orange juice or grapefruit will supply the needed vitamin C that your body needs to reduce the risk of gastrointestinal tract, lung and cervix cancers.
Vegetables provide healthy doses of various vitamins, antioxidants and fiber.
Asparagus, broccoli, garlic, guava, mushrooms and tomatoes have been found to provide potent substances in the fight against cancer. Include 3-5 servings of vegetables each day. Though protein rich foods don't necessarily provide protection from cancer, the one meat that does offer help is fish. The omega-3 fatty acids in fish many slow or prevent tumor growth. Dairy products should be low fat or non-fat.
