What is the USDA MyPlate Grains Group? The MyPlate Grains Group is one of the five food groups. Any food made from wheat, rice, oats, cornmeal, barley, or another cereal grain is a grain product. Bread, pasta, breakfast cereals, grits, and tortillas are examples of grain products. Foods such as popcorn, rice, and oatmeal are also included in the MyPlate Grains Group. Grains are divided into 2 subgroups: Whole Grains and Refined Grains.
