"Traditional" in the context of these projects means pre-contact foods. No beef, mutton, goat, chicken, pork, milk, butter, cream, wheat flour (no fry bread), rye, barley, okra, black-eyed peas, or any other "Old World" food that many of us have lovingly incorporated into our diets and tribal cultures. No processed foods (Doritoes, Lays Chips, etc), even if the base is corn or potatoes. No chocolate unless it is unsweetened cacao or sweetened with honey from the Melipona bee, fruit, stevia, camas or agave. Be adventurous and try unfamiliar foods! There are many foods to choose from. My American Indian Health and Diet Project site lists and defines many of them.
