What is a whole grain?
We all know whole grain is good for our health. But do we actually know what it is?
A whole grain is just that—whole. It's the grain seed in its pure form. All whole grains start out as whole grains. Refined grains, like white flour, capture only the endosperm—the bran and the germ aren't used, so vitamins, minerals, fibers, phytonutrients, and antioxidants disappear. The bran is the outside shell that protects the seed, which contains fiber, vitamin B, and trace minerals. The germ provides the nourishment for the seed and holds antioxidants and vitamins E and B.
Corn, or maize, is a grain like wheat or rice only the grain head, the ear, is greatly enlarged.
