The Benefits of Fiber ( Diabetes )
High-fiber diets may be beneficial to you, particularly if you have high blood fats or impaired glucose tolerance. Fiber is found primarily in fruits, vegetables, beans, and cereals, such as wheat and oats. Insoluble fibers like cellulose, found in wheat bran and celery, are dense and chewy. Soluble fibers, found in foods like whole oats and green peas, soften when mixed with water. Most fiber is not absorbed by the body, so it passes out in the stool. Any compounds that are bound by fiber in the intestine are also not absorbed.
There have been many studies about the benefits of fiber. Most studies show the positive (although limited) effects of fiber on blood fats. That’s why high-fiber diets usually lower blood cholesterol. Some studies (primarily on people with type 2 diabetes) have also shown an improvement in blood glucose levels, but this improvement is usually small. You can add high-fiber foods, such as whole grains and beans, to your meals. Another way to increase the fiber in your diet is to take a tablespoon of pseudophilin (Metamucil) before you go to sleep.
