Anatomy of a whole grain
Whole grains include the bran, germ and endosperm. The bran is the outer layer of the seed and contains most of the seed's fiber. The endosperm, also called the kernel, makes up the bulk of the seed. It contains small amounts of vitamins and minerals. The germ is the part of the seed from which a new plant sprouts. It's a concentrated source of nutrients.
