Meat is animal meat eaten as food. Since prehistory, humans have been hunting animals and eating meat. The emergence of civilization enables people to domesticate animals such as chickens, sheep, pigs and cattle. This eventually led to their industrial use in meat production with the help of slaughterhouses.

Meat is mainly composed of water, protein and fat. It's an edible ingredient, but it's usually cooked, seasoned or processed in various ways. Unprocessed meat spoils or rots within hours or days due to bacterial and fungal infection and decomposition.

Meat usually refers to skeletal muscle and related fat and other tissues, but it can also describe other edible tissues, such as viscera. Sometimes, meat is also used in a more strict sense, referring to the meat of mammals (pigs, cattle, lambs, etc.) raised and prepared for human consumption, but excluding fish, other seafood, poultry or other animals.

Meat consumption varies around the world, depending on cultural or religious preferences and economic conditions. Vegetarians choose not to eat meat because of moral, economic, environmental, religious or health concerns related to meat production and consumption.
