Wheat was introduced in Mexico by the Spaniards around 1520, and to early American colonists in the 1600's . At that time it was not popular in New England due to the soils and climate, but in the mid 1800's wheat was grown from seeds introduced by migrating Europeans and agricultural scientists in the area that would later be called the "Wheat Belt."
Wheat is generally grown intended for food for humans, but lesser quality wheat and the nutrient-dense by-products of flour refining are used for animal feed. Wheat is also used for whiskey and beer production, and the husk can be separated and ground into bran. Before the introduction of corn into Europe, wheat was the principal source of starch for sizing paper and cloth.
