In old and Middle English, the word for all crops was "corn." This word has since come to be used in America as a term for sweet corn, or maize. Maize usually is consumed without milling, so it retains much of its nutrients and remains high in dietary fiber. It usually is turned into food products such as pop corn, corn on the cob, cornflakes, and puffed maize. It is a staple food of many countries, including those in Latin America and North America.
