The agricultural diet of the Cahokians consisted mainly of corn, squash, and sunflowers, which lacked important nutrients. Corn provided calories but lacked vitamins and protein. While crops were easy to harvest, the diet lacked nutrition needed for a healthy lifestyle. Some advantages were that the crops filled people up without much food and grew quickly to feed many. However, meat was also important for protein, vitamins and minerals, and the agricultural diet did not include enough meat for good health.
