Whole grains are foods prepared from the whole grain seed, typically called the kernel, which is made up of the bran, germ, and endosperm. If the kernel has been broken, crushed, or flaked, it must preserve just about the same relative proportions of bran, germ, and endosperm as the initial grain to be called whole grain

Brown rice is unmilled or partially milled rice, a type of whole grain. It has a slight nutty flavor, is chewier than white rice, becomes stale more quickly, but is far healthier. Any rice—sticky rice, long-grain rice, or short-grain rice, may be eaten as brown rice.
