Fiber in Your Diet

Why do I need fiber in my diet?

Dietary fiber is the part of plants that cannot be digested. There are 2 kinds of dietary fiber. Insoluble fiber adds bulk to keep foods moving through the digestive system. Soluble fiber holds water which, in turn, softens the stool for easy bowel movements. Fiber is an important part of your diet even though it passes through your body. A high-fiber diet can:

• Reduce cholesterol levels.
• Help you have regular bowel movements.
• Improve you blood sugar level if you have diabetes.
• Treat diverticular disease (inflammation of part of the intestine) and irritable bowel syndrome (abdominal pain, diarrhea, and constipation that come and go).
• Help you lose weight. High-fiber foods are usually lower in calories and provide a feeling of fullness.

If you do not have enough fiber in your diet, you may have constipation. Your bowel movements may be small, hard, and dry.

What foods contain fiber?

Breads, cereals, and pasta made with whole-grain flour or brown rice are high-fiber foods. Many breakfast cereals list the bran or fiber content, so it's easy to know which products are high in fiber.

All fruits and vegetables also contain fiber. Dried beans, peas, nuts, leafy vegetables, raisins, prunes, apples, berries and citrus fruits are all especially good sources of fiber.

How much fiber do I need in my diet?

You should have at least 14 grams of fiber for every 1000 calories that you eat every day. Read the label on food packages to find out how much fiber a serving of a food will provide. Foods containing more than 20% of the daily value of fiber per serving are considered high in fiber.

What can I do to increase fiber?

When increasing the fiber in your diet, it is best to do so slowly, because large, sudden increases can cause discomfort, gas, and bloating. Start with small changes, like switching to whole-grain bread, and add a new source of fiber each week or two. You may have some gas or bloating at first, but your body will usually adjust in time. If you keep having uncomfortable gas, you can try a natural enzyme supplement that helps to digest the gas-forming part of plant foods. The enzyme is sold in liquid and pill form and you don't need a prescription for it.

• Start your day with a high-fiber breakfast cereal.
• Buy more fruits and vegetables. If you buy them, you are more likely to eat them. Use carrot sticks or apple slices for snacks. Include fruits or vegetables with every meal. Cooked fiber is just as effective as raw fiber.
• Eat whole-grain breads.
• Add whole grains, dried beans, and vegetables to casseroles.
• Serve fruit-based desserts.
• If you have constipation even though you have added high-fiber foods to your diet, make sure you are enough fluids and talk to your healthcare provider about fiber laxatives. Psyllium is a soluble fiber that is often used for this purpose. It can be taken as a pill or as a powder that is mixed in a glass of water. Always read and follow the directions on the label carefully.

Adding fiber to your diet is easy, and a high-fiber diet can provide long-term health benefits.
