bran the husks which are removed when grain is milled to produce flour. The husks usually have a part of the endosperm adhering to them; the more the better in terms of the value of the bran.

It was often an ingredient of animal feed, but its health benefits have promoted it to a human nutrient, either as part of bread or in breakfast cereal.
