According to this infographic from Nationwide Bank, the first Thanksgiving ever was in 1621. What was on the menu? Wild goose or duck, wild turkey, deer, flint corn, fish, shellfish, and eel—pretty different from today's traditional feast of turkey, mashed potatoes, stuffing, cranberry sauce, gravy, and corn. We also learned that you can no longer blame tryptophan for your turkey coma. As it turns out, other meats also contain comparable levels of it. All those carbs are what truly makes you tired!
