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.
A major role of insoluble fibre is to add bulk to faeces and to prevent constipation and associated problems such as haemorrhoids. Good sources include wheat bran, corn bran, rice bran, the skins of fruits and vegetables, nuts, seeds, dried beans and wholegrain foods.
