Wheat bran is the outer layers of the wheat grain kernel. It's separated from the inner layers during milling. It's rich in soluble and insoluble fiber.
Wheat bran has laxative effects that can increase stool volume and bowel frequency. It also contains proteins, fats, carbohydrates, minerals, vitamins, and antioxidants.
People use wheat bran for constipation, hemorrhoids, and irritable bowel syndrome (IBS). It is also used for colon cancer, diabetes, high cholesterol, and many other conditions, but there is no good scientific evidence to support most of these uses.
Wheat is considered a major food allergen in the US. Wheat contents, including wheat bran, must be labeled on packaged foods and supplement products.
