Wheat bran is the outer layer of the wheat grain, separated during milling. The figures here describe wheat bran rather than a prepared bran cereal. It mainly provides fibre, carbohydrate and protein, with some fat. Per 100g, it contains 41g of fibre, 21g of carbohydrate, 15g of protein and 5.5g of fat. It also provides several B vitamins and minerals, including magnesium and iron.

Fibre helps support normal bowel function, while protein is needed for the growth and repair of body tissues. Wheat bran contains gluten and is not suitable for people with coeliac disease. Its salt and saturated fat contents are low. Full nutrient figures are shown in the tables below.
