All traditional cultures consume some sort of animal food:fish and shellfish, land and water fowl, land and sea mammals, eggs, milk and milk products reptiles, and insects. Sally Fallon Morell, the head of the Weston A. Price Foundation, explains why this is principle #2 of the Wise Traditions diet. She goes into detail about what nutrients are bio-available in animal products and why many traditional cultures considered these foods to be "sacred." She also addresses what to do if you have trouble digesting meat or if you prefer not to eat meat altogether. If you want to regain or maintain your health, Sally has some very practical suggestions about how to incorporate this principle into your current diet.
