Oat Flakes are made from steamed whole oats that are rolled out to flatten. The flattened oats are then flaked into small pieces of material, which will cook very quickly while retaining the nutritional value of whole oats. Oats are extremely high in fiber, especially when eaten whole, and they contain a number of other useful vitamins and minerals. Eat oat flakes as a breakfast cereal, by heating them and mixing them with an assortment of ingredients. They can also be added to baked goods like scones, muffins, cookies, and bread, creating additional texture and adding to the nutritional value of this food.
