  Maize and cornmeal (ground dried maize) constitute a staple food in many regions of the world. Maize is used to produce the food ingredient cornstarch. Maize starch can be hydrolyzed and enzymatically treated to produce high fructose corn syrup, a sweetener. Maize may be fermented and distilled to produce Bourbon whiskey. Corn oil is extracted from the germ of the grain.
  
  In prehistoric times, Mesoamerican women used a metate quern to grind maize into cornmeal. After ceramic vessels were invented the Olmec people began to cook maize together with beans, improving the nutritional value of the staple meal. Although maize naturally contains niacin, an important nutrient, it is not bioavailable without the process of nixtamalization. The Maya used nixtamal meal to make porridges and tamales. Maize is a staple of Mexican cuisine. Masa (nixtamal) is the main ingredient for tortillas, atole and many other dishes of Central American food. It is the main ingredient of corn tortilla, tamales, atole and the dishes based on these. The corn smut fungus, known as huitlacoche, which grows on maize, is a Mexican delicacy.
  
  Coarse maize meal is made into a thick porridge in many cultures: from the polenta of Italy, the angu of Brazil, the mămăligă of Romania, to cornmeal mush in the US (or hominy grits in the Southern US) or the food called mieliepap in South Africa and sadza, nshima, ugali and other names in other parts of Africa. Introduced into Africa by the Portuguese in the 16th century, maize has become Africa's most important staple food crop.
  
  Sweet corn, a genetic variety that is high in sugars and low in starch, is eaten in the unripe state as corn on the cob.
