Thanksgiving feasts have evolved since the first shared meal at Plymouth Colony in 1621. There is still a familiar cast of ingredients that make up what is now traditional at Thanksgiving including: turkey, corn, squash, and cranberries. These foods reflect changes in how we have grown, cooked, and eaten food in America. Turkeys were an important source of nutrients among native peoples of Central and South America. The type of turkey enjoyed most frequently in North America today is related to the wild birds found north of the Rio Balsas in Mexico.
