A whole grain is a grain that consists of all of the original components that were present when it was growing in the field. Refined grains, on the other hand, have had some of the components removed to give them a better texture and a longer shelf life. These refined grains are more commonly used and find their way into our diets more often. However, recent studies indicate that it may be best to skip refined grains altogether, in favor of the whole grain alternatives. http://bit.do/b2s9J
