Turkey is a large, widely domesticated North American bird with white plumage and a bare, wattled head and neck. The name turkey was originally applied to an African bird now known as the guinea fowl, which was believed to have originated in Turkey. When the Europeans came upon the American turkey, they thought it was the same bird as the African guinea fowl, and so gave it the name turkey, although the two species are quite distinct. Turkey is low in fat and high in protein. It is an inexpensive source of iron, zinc, phosphorus, potassium and B vitamins. Did you ever wonder why the breast and wings of chickens and turkeys have white meat while the legs and thighs are dark? The explanation is a physiological one involving the function of muscles, which gives some insight into humans as well as animals. The dark coloration is not due to the amount of blood in muscles but rather to a specific muscle type and it's ability to store oxygen.
