What kinds of foods are grains?

* Whole grains: These are grains that have not been refined, meaning that they still contain all of their bran, germ, and endosperm. Some examples of whole grains include brown rice, whole wheat, and oats.

* Refined grains: These are grains that have been processed to remove the bran and germ, leaving only the endosperm. Some examples of refined grains include white rice, white flour, and cornmeal.
