Meat is animal flesh that is consumed as food. Humans have been hunting, raising and gathering animals for meat since prehistoric times. The creation of settlements in the Neolithic Revolution made it possible to domesticate animals such as chickens, sheep, and cows. This eventually led to their use in meat production on an industrial scale in slaughterhouses.Meat is mainly composed of water, protein and fat. It is edible raw, but it is usually eaten after being cooked and seasoned or processed in different ways.
