Corn plays a key role in Native American cultures. It was very honored because of its ability to provide not only sustenance as food but also as a shelter, fuel, and other decorations. Because of the vital role that corn plays in the livelihoods of many indigenous cultures, it is one of the most important icons represented in the mythological traditions of the Mayas, Aztecs and Incas.
Traditional dishes made from corn often include a small amount of lime - calcium oxide mineral complex which is produced by burning limestone. It is now known why the ancient civilizations have resorted to this unusual combination. Niacin or vitamin B3 in corn is readily available for absorption in the body and limestone helps to release the vitamin, making it available for absorption.
Corn is transported to Europe by the Spanish and Portuguese explorers, and later in the rest of the world. Today, the largest commercial producers of corn are the U.S., China, Brazil, Mexico and the Russian Federation.

Seven are the most common types of corn. These are:
- Dent corn - known as field corn. This type of corn has kernels, which contain hard and soft starch in the course of their maturation and are formed in the shape of a tooth. Field corn is a major crop that is used not only for human but for animal feed. This is only one of seven species of maize, which is used to make corn starch;
- Waxy maize – it’s kernels resemble wax inside. They contain starch, but only branched off type. Waxy maize starch contains more than 99% amylopectin, whereas ordinary field corn - up to 76% amylopectin and 28% amylose. Waxy corn processing is performed by wet grinding in order to get waxy maize starch, which then slowly regains its crystalline form. This type of corn is grown to meet the needs of special starches for curing food, especially those who are subjected to very high heat treatment;
- Flint corn - hard and angular, short or rounded grains that contain soft endosperm starch, surrounded by a hard outer layer. Much of it is grown in South America, identical to dent corn and is used for the same purposes.
- Pop corn - also known as Popcorn, this maize has round or pointed tips and very hard endosperm. When exposed to very high temperatures, the grains burst through the expulsion of moisture and they produce a white starchy mass / popcorn / which exceed several times their original size;
- Corn Flour - is made up almost entirely of soft starch. In America it is grown blue corn flour used to make corn chips, and products. In South America, corn flour is grown in many different colors and used for the production of beer and food;
- Indian corn - red, white, purple, or brown colored kernel beans. Used to decorate on various holidays, especially Halloween.
