Knowing the food groups can help you get the nutritious foods you need.
Grains
Any food made from wheat, rye, rice, oats, cornmeal, barley, or another cereal grain is a grain product. In addition to bread and pasta, there are cereal, rice, grits, tortillas, even popcorn. Many people find it easy to eat more grains than needed.
Look for grain choices that are low in saturated and trans fat and low in added sugar when possible. But be careful—low-fat baked goods can be high in added sugar.
