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 germ is the part of the seed that grows into a new plant. It has lots of vitamins and minerals. The endosperm is the energy source for a seed.
What is the healthiest whole grain?
