With the Pyramid search method, we use the standard major categories as used by the academic and professional institutions: Breads, grains & Cereal, Fruits, Vegetable, Meats & Protein, Fats, Oils and Sweets, and Dairy & Milk. Raw food fall easily into a single category; however, some processed food may be a combination of several categories in which case some logical determinations may be required to locate it (try content percentage).
