Red meat
In gastronomy, red meat is commonly red when raw (and a dark color after it is cooked), in contrast to white meat, which is pale in color before (and after) cooking. In culinary terms, only flesh from mammals or fowl (not fish) is classified as red or white. In nutritional science, red meat is defined as any meat that has more of the protein myoglobin than white meat. White meat is defined as non-dark meat from fish or chicken (excluding the leg or thigh, which is called dark meat). Definition Under the culinary definition, the meat from adult or "gamey" mammals (for example, beef, horse, mutton, venison, boar, hare) is red meat, while that from young mammals (rabbit, veal, lamb) is white. Poultry is white, excluding certain birds such as ostriches. Most cuts of pork are red, others are white. Game is sometimes put in a separate category altogether. (French: viandes noires — "dark meats".) Some meats (lamb, pork) are classified differently by different writers. According to the United States Department of Agriculture (USDA), all meats obtained from mammals (regardless of cut or age) are red meats because they contain more myoglobin, which gives them their red color, than fish
