Grains are generally divided into 2 subgroups,
Whole Grains and
Refined Grains. Whole grains contain the entire grain kernel while refined grains have been processed to remove the bran and germ. Grains are processed to give the grain a finer texture and improve their shelf life. However, the processing of the grain removes dietary fiber, iron, and vitamins that are extremely useful to our bodies. Ideally all of our daily grains would be whole grains however that may be somewhat difficult, so the USDA recommends that half of all the grains we eat should be whole grains.
