What are grains?
Foods made from wheat, rice, oats, cornmeal, barley, or another cereal grain are grain products. Bread, pasta, breakfast cereals, grits, and tortillas are examples of grain products. Foods such as popcorn, rice, and oatmeal are also included in the Grains Group.
Grains have two subgroups: whole grains and refined grains. (Source: myplate.gov)
