Foods that are considered whole grains include items like brown rice, quinoa, oats, barley, and whole wheat products. Whole grains are designated as such because they contain all parts of the grain kernel—the bran, germ, and endosperm—making them rich in essential nutrients and dietary fiber. Unlike refined grains, which have been stripped of key nutrients during processing, whole grains are associated with numerous health benefits, including reduced risks of heart disease, improved digestion, and better weight management.
