There are two main types of grain products.
- Whole grains contain the entire grain kernel-the bran, germ, and endosperm. (See the whole grain kernel graphic.) Examples include whole-wheat flour, bulgur, oatmeal, rye bread, whole cornmeal, and brown rice.
- Refined grains have been milled-the bran and germ are removed. This process also removes much of the B vitamins, iron, and dietary fiber. Some examples of refined grains are wheat flour, enriched bread, and white rice. Some refined grains are enriched. This means certain B vitamins (thiamin, riboflavin, niacin, folic acid) and iron are added back after processing. Fiber is not added back to most enriched grains.
