One of the important conditions for the full functioning of the body is the intake of dietary fiber into it. Although these components of products are not practically absorbed by the body, they still perform an important function in it. Dietary fiber is fiber , ballast substances, indigestible, non-digestible carbohydrates.
Types of dietary fiber in food
- Insoluble fibers . Products with these food fibers: wheat bran, rind of broccoli, apple, carrot and celery, grapes, beans, beets, pear, nuts. Insoluble fiber is essential for the proper functioning of the gastrointestinal tract. These fibers can not be digested by the body. In the intestine, they form a dense mass, which helps digested food to pass through the intestinal tract. Sufficient intake of fruits and vegetables with insoluble fibers is the prevention of constipation, hemorrhoids, and colitis.
- Soluble fiber . Products containing soluble dietary fiber: oat bran, carrots, flaxseed, various fruits, sunflower seeds, blackberries, watermelon, dried fruits , black bread, beans. This type of fiber in the intestine combines with water and acquires the consistency of the gel. The resulting gel mass promotes the binding in the intestine of slags, toxins, the products of vital activity of pathogenic microorganisms and their removal from the body.
A lot of fruits and vegetables contain two types of fiber. For example, the apple peel is rich in insoluble fiber, and the pulp is soluble.
In addition to the main function - to improve the work of the intestines - cellulose performs several other functions. The use of foods rich in dietary fiber, helps normalize blood pressure, insulin and glucose levels, reduce cholesterol, and maintain a feeling of satiety.
