Insoluble fiber is found in wheat and corn bran, grains, and some vegetables, including the skins of fruits and root vegetables. Pectin is found in most fresh fruits and vegetables, and gums are found in such foods as oat bran, barley and beans. Soluble fiber is also associated with controlling blood sugar levels, since it delays transit time and the absorption of glucose in the blood. Protein Like carbohydrate, protein provides calories that can be used by the body as a source of energy, but there are many vital functions that only protein can perform. For instance, proteins are part of enzymes, which are compounds that facilitate and accelerate chemical reactions throughout the body.
Proteins also serve as building materials for the growth and repair of body tissues.
The basic building blocks of protein are called amino acids. Your body can produce 11 of them, but nine of them are essential, meaning they must be supplied by the diet. Complete proteins contain ample amounts of all essential amino acids. But don't be fooled by the word incomplete. Although they do not have all nine essential amino acids, these proteins can make a complete protein when they are combined appropriately.
