Bran
Bran refers to the outer, fibre-rich layers of the grain kernel. Wheat bran, for example, consists of the husks, the aleurone layer and the wheat germ of the wheat kernel. Bran generally contains almost 80 percent of all nutritionally valuable substances. At the same time, it is rich in minerals (phosphorous, magnesium), trace elements (iron, manganese and zinc) and vitamins (vitamin E, B vitamins).
