Grains have been cultivated and eaten by different cultures for thousands of years. In North America, the most popular grain is wheat, although we do eat a lot of corn and rice as well. Barley and oats are other common grains we eat. Grains are high in fibre, iron, and other important nutrients. The less processed the grain, the more fibre, vitamins, and minerals it contains. That's why whole grain foods are healthiest.
