Refined grains: have been milled, a process that removes the bran and germ; What does enriched grains mean? gives grains a finer texture and improve their shelf life, but it also removes dietary fiber, iron, and many b vitamins. Ex: white flour, degermed cornmeal, white bread, white rice. Enriched grains: this means certain b vitamins (thiamin, riboflavin, niacin, folic acid) and iron are added back after processing; fiber is not added back.
