Oats are grown in temperate regions. Oats have numerous uses in foods; most commonly, they are rolled or crushed into oatmeal, or ground into fine oat flour. Oats are also occasionally used in several different drinks. Oats are the only cereal containing a globulin or legume-like protein, avenalin, as the major (80%) storage protein. Oats remove substantial amounts of nitrogen from the soil.
