Whole grains are cereal grains that retain the bran and germ as well as the endosperm, in contrast to refined grains, which retain only the endosperm. Whole-meal products are made from whole-grain flour.Common whole-grain products include oatmeal, popcorn, brown rice, whole-wheat flour, sprouted grains, and whole-wheat bread. Common refined-grain products include white rice (raw rice; parboiled rice however retains some of the "wholeness"), white bread, hominy, and pasta (although whole-grain varieties of pasta are available).
