Answer:
Soluble and insoluble fibers are the two types of fiber. Both are important for good health, digestion, and disease prevention.
Water attracts soluble fiber, which transforms to gel during digestion. Digestion is slowed by this. Oat bran, barley, nuts, seeds, beans, lentils, peas, and some fruits and vegetables contain soluble fiber. Psyllium, a common fiber supplement, also contains it.
Some forms of soluble fiber have been shown to help reduce the risk of heart disease.
Wheat bran, fruits, and whole grains are all high in insoluble fiber. It thickens the stool and appears to speed up the passage of food into the stomach and intestines.
