Chili is widely used, although in much of South America the plant and its fruit are better known as ajÃ, locoto, chile, or rocoto. However, this spelling is discouraged by some in the United States of America, since it also commonly refers to a popular Southwestern-American dish (also known as chili con carne (literally chili with meat); the official state dish of Texas), as well as to the mixture of cumin and other spices (chili powder) used to flavor it. Chili, as in the case of Cincinnati chili, can also refer to ground beef stews that do not actually contain any chile peppers. Chili powder and chile powder, on the other hand, can both refer to dried, ground chili peppers. Chili pepper (also known as, or spelled, chilli pepper, chilli, chillie, chili, and chile) is the fruit of the plants from the genus Capsicum, members of the nightshade family, Solanaceae. Botanically speaking, the fruit of capsicums are berries. Depending on flavor intensity and fleshiness, their culinary use varies from use as a vegetable (eg. bell pepper) to use as a spice (eg. cayenne pepper). It is the fruit that is harvested. Chili peppers originated in the Americas; and their cultivars are now grown around the world, because they are widely used as food and as medicine. Red chilis contain high amounts of vitamin C and carotene ("provitamin A"). Yellow and especially green chilis (which are essentially unripe fruit) contain a considerably lower amount of both substances. In addition, peppers are a good source of most B vitamins, and vitamin B6 in particular. They are very high in potassium and high in magnesium and iron. Their high vitamin C content can also substantially increase the uptake of non-heme iron from other ingredients in a meal, such as beans and grains.
