Dietary fiber is a general name for indigestible polymer components in food that cannot be broken down by human digestive enzymes. Dietary fiber is classified as either soluble or insoluble. Examples of soluble fiber include alginic acid found in kelp, and konjac-mannan found in konjac ("yam cake"). Fibe-Mini is made from polydextrose, which is also a soluble fiber. Examples of insoluble fiber include cellulose and hemicellulose, which are found in vegetables, beans, and grains.
