Sometimes referred to simply as dietary fiber, it is understood to be an essential part of any healthy diet plan. Its main function is to add bulk to the diet, which in turn aids in the digestion process and healthy function of the bowel system.

Whole grains also contain dietary fiber, and many people eat wheat products like whole grain bread and crackers to add bulk to the diet. Vegetables of just about every description from kale to potatoes also are considered to have bulk.
