Corn chips do not count as a vegetable (but the salsa you might dip them into does!). They are made from a variety of corn that is actually a grain, not a vegetable. There are many different forms of corn – blue corn, maize, popcorn, sweet corn, to name a few. It is sweet corn that is eaten as a vegetable. Sweet corn is a variety of maize that has naturally altered genetically from field corn and is picked when immature. It contains more sugar and water than the forms of corn that are used as grains.
