Grains
Edible seeds of grasses such as wheat, rice, oats, barley, and corn. Grains provide carbohydrates, fiber, protein, vitamins, and minerals. Whole grains retain bran and germ, offering more nutrients and health benefits compared to refined grains, which are stripped of fiber and micronutrients. The FDA recognizes whole grains as part of a healthy diet.
