The B-vitamin content of a whole grain is dramatically decreased during the refining process. Grain is the harvested seed of grasses such as wheat, oats, rice, and corn. Thankfully, scientists set out to replicate man-made vitamins that were then to be added back into bread during production, “enriching” the bread. Grains are also used to feed livestock and to manufacture some cooking oils, fuels, cosmetics, and alcohols.Almost half of the grains grown around the world are harvested for people to eat directly.
