Polysaccharides that cannot be digested by human digestive enzymes, and therefore cannot be absorbed, are called fiber. It is a type of a carbohydrate that the body could not process or metabolize. It passes in the body as it is or undigested. Although, the presence of fiber is not really dangerous rather it is very helpful in regulating the use of the body of the sugars present and aid in keeping hunger and blood sugar at normal level. Daily recommended intake of fiber for both adults and children would be 20 to 30 grams to keep a good health. Sources of this are vegetable and whole fruits, grains and beans.
