The American Dietetic Association and Dietitians of Canada have created a food guide that covers different types of vegetarian diets, meets the most recent health recommendations, focuses on nutrients of particular interest in vegetarian diets, and includes a wide variety of vegetarian foods. The guide includes a pyramid and rainbow diagram.
