Wheat bran is mostly used to treat and prevent constipation because it provides 6 g of dietary fiber per quarter cup. Wheat bran is primarily insoluble fiber, which helps provide bulk to your stool and can help you pass stool faster. Unlike soluble fiber, wheat bran does not absorb water during digestion but instead remains undigested, helping to move the stool along the digestive wall faster.
Getting enough fiber in your diet (20 to 35g per day) helps prevent constipation. Vegetables, fresh fruits (especially dried fruits) and whole grains, including wheat and bran, or oatmeal cereals, are excellent sources of fiber.
