White meat

White meat or light meat refers to the lighter-colored meat of poultry, as contrasted with dark meat. In a more general sense, white meat may refer to any lighter-colored meat, as contrasted with red meats like beef and some types of game.

White meat is made up of fast-twitch muscle fibres, while red, or dark, meat is made up of muscles with fibres that are slow-twitch.

Given nutritional concerns, meat producers are eager to have their products considered white meat, and the United States National Pork Board has positioned their product as "Pork. The Other White Meat", alongside poultry and fish; this follows the traditional gastronomic classification. However, meats which are red when raw and turn white on cooking, like pork, are categorized by the United States Department of Agriculture as red meats if the myoglobin level is higher than 65%, and this is the definition used in nutritional studies. This categorization is controversial as some types of fish, such as tuna, are red when raw and turn white when cooked; similarly, certain types of poultry that are sometimes grouped as "white meat" are actually red when raw, such as duck and goose. In contrast, the USDA considers all meat from mammals to be "red meat."

In Israel, where Jewish dietary laws are popularly practiced, forbidding the consumption of pork, "white meat" is the accepted euphemism for pork.

Within poultry, there are two types of meats—white and dark. The different colors are based on the different locations and uses of the muscles. White meat can be found within the breast of a chicken or turkey. These muscles are designed to develop endurance, or long-term use and contain little myoglobin, allowing the muscle to use oxygen more efficiently for aerobic respiration. The white meat contains large amounts of protein.
