Most days I can't remember how many servings of fruit I'm supposed to have, let alone the correct serving size. I don't have a food pyramid poster handy and, as much as I'd like to make sure I'm eating all my food groups in the correct proportions, it's not particularly easy to determine just what should be in a healthy meal. The Pyramid Lunch Box simplifies matters. Designed by Li Jianye from Yanko Design, the Pyramid Lunch Box is a triangle divided into three compartments of varying size. The largest is meant to hold bread and other carbohydrates--the foods that the food pyramid suggests we should eat the most of. A slightly smaller compartment is for fruits and vegetables and the smallest is for meat and other proteins. No compartment for sweets, I'm afraid. Not only does the Pyramid Lunch Box help you plan your meal to make sure that you're including items from all the necessary food groups, the compartments are also sized to match serving requirements, helping to keep portion size under control. The Pyramid Lunch Box has a matching triangular lid. While I do think that the Pyramid Lunch Box is a perfect tool for packing a lunch, I'm not so sure I'd want to eat out of it: I like mixing up my grains, vegetables and proteins.
