Chicken as food

Chicken is the most common type of poultry in the world. Owing to the relative ease and low cost of raising chickens—in comparison to mammals such as cattle or hogs—chicken meat (commonly called just "chicken") and chicken eggs have become prevalent in numerous cuisines. Chicken can be prepared in a vast range of ways, including baking, grilling, barbecuing, frying, and boiling. Since the latter half of the 20th century, prepared chicken has become a staple of fast food. Chicken is sometimes cited as being more healthful than red meat, with lower concentrations of cholesterol and saturated fat. The poultry farming industry that accounts for chicken production takes on a range of forms across different parts of the world. In developed countries, chickens are typically subject to intensive farming methods while less-developed areas raise chickens using more traditional farming techniques. The United Nations estimates there to be 19 billion chickens on Earth today, making them outnumber humans more than two to one. The modern chicken is a descendant of red junglefowl hybrids along with the grey junglefowl first raised thousands of years ago in the northern parts of the Indian subcontinent. Chicken as a meat has been depicted in Babylonian carvings from around 600 BC. Chicken was one of the most common meats available in the Middle Ages. For thousands of years, a number of different kinds of chicken have been eaten across most of the Eastern hemisphere, including capons, pullets, and hens. It was one of the basic ingredients in blancmange, a stew usually consisting of chicken and fried onions cooked in milk and seasoned with spices and sugar. In the United States in the 1800s, chicken was more expensive than other meats and it was "sought by the rich because [it is] so costly as to be an uncommon dish." Chicken consumption in the U.S. increased during World War II due to a shortage of beef and pork. In Europe, consumption of chicken overtook that of beef and veal in 1996, linked to consumer awareness of Bovine spongiform encephalopathy (mad cow disease).
