What Is Fiber?
- Soluble fiber draws water into the bowel and can help slow digestion. Examples of foods that are high in soluble fiber include oatmeal, oat bran, barley, legumes (eg, beans and peas), apples, and strawberries.
- Insoluble fiber speeds digestion and can add bulk to the stool. Examples of foods that are high in insoluble fiber include whole-wheat products, wheat bran, cauliflower, green beans, and potatoes.

Tips for Increasing Fiber Intake
- Whenever possible, choose whole grains over refined grains (eg, brown rice instead of white rice, whole-wheat bread instead of white bread).
- Include a variety of grains in your diet, such as wheat, rye, barley, oats, quinoa, and bulgur.
- Eat more vegetarian-based meals. Here are some ideas: black bean burgers , eggplant lasagna , and veggie tofu stir-fry .
- Choose high-fiber snacks, such as fruits, popcorn, whole-grain crackers, and nuts.
- Make whole-grain cereal or whole-grain toast part of your daily breakfast regime.
- When eating out, whether ordering a sandwich or dinner, ask for extra vegetables.
- When baking, replace part of the white flour with whole-wheat flour. Whole-wheat flour is particularly easy to incorporate into a recipe.
