Corn is considered both a vegetable and a cereal grain.
Sweet corn that you eat off the cob is usually considered a vegetable in the culinary world, whereas the dry seeds that are used for popcorn are classified as whole grains.
Corn originated in Mexico over 9,000 years ago and is known by its original name â€œmaizeâ€ in many parts of the world. Native Americans grew and harvested this crop as the main source of food (1Trusted Source, 2Trusted Source).
Today, itâ€™s one of the most widely consumed cereal grains worldwide (3). Corn is usually white or yellow but also comes in red, purple and blue. Itâ€™s eaten like sweet corn, popcorn, tortillas, polenta, chips, cornmeal, grits, oil and syrup and added to countless other foods and dishes.
Whatâ€™s more, itâ€™s widely used for fuel and animal feed. In fact, 40% of the corn grown in the US is used for fuel and 60â€“70% of corn worldwide is produced to feed animals (2Trusted Source, 4Trusted Source).
