White bread is in the grain food group. The grain food group has two subgroups: whole grains and refined grains. The entire grain kernel is used in whole grains, while the bran and germ has been removed in refined grains. According to the United States Department of Agriculture, when bran and germ are removed, so is iron, dietary fiber and many B vitamins. White bread is a refined grain, while whole-wheat bread is a whole grain. Nutritional values are based on a one-slice serving of thin white bread.
