When human consume food, nutrients including carbohydrates, proteins and fats are digested and absorbed as calories in the digestive tract in the small intestine. Dietary fiber is the only substance that is not broken down and digested by human digestive enzymes, and it reaches to the large intestine, excreted out to the body, without being taken into the body.

Did you know that there are 2 types in the Dietary Fibers?:insoluble fibers and water-soluble fibers. 
Insoluble fibers have coarse mouth-feel and are found in bran, cereals, vegetables used in salad, peas and legumes.
They absorb water and increase the volume in the intestines, and help increase the volume of stool by promoting the bowel movement, which keeps you away from colon cancer.
Water-soluble fiber makes a smooth gel in water. RHEOLEX^® vegetable, seaweed and some types of yams contain water-soluble fiber. The water-soluble fibers prevent the elevation of blood sugar level and cholesterol, by slowing down the speed
of absorption into the small intestines, which is a very good news for those with diabetes and hyper-lipidemia.
