As human food, corn is eaten fresh or ground for meal. It is the basic starch plant of Central and Andean South America, where it is still hand ground on metates to be made into tamales, tortillas, and other staple dishes. In the S United States it is familiar as hominy, mush, and grits. Starch, sugar, and oil are also extracted for many products, but the chief use of corn is as animal fodder. It is the primary feed grain of the United States, and in Europe this is almost the only use of corn. Corn is also as a raw material in the manufacture of ethanol for fuel; some 40% of the U.S. crop is so used.
