| Whole grain | Whole grains are cereal grains which retain the bran and germ as well as the endosperm which are the 3 major parts of the grain. Iin contrast, refined grains retain only the endosperm. The whole truth is if the label doesn't say "100% whole grain," check the ingredient list to see if the food contains any refined grains or flour. Dead giveaways are enriched or unbleached wheat flour, semolina flour, durum flour, and rice flour. Enriched grains: A term usually applied to flour that, after the milling has stripped it of the germ and the bran and other nutritious elements, has niacin, riboflavin and thiamin added back into it. U.S. law requires that flours not containing wheat germ must have these nutrients replenished. |
