US rating system could prove a recipe for success

IT seems like a tasty idea: a simple, easy-to-digest rating system for food on your shop shelf.

Based on a scale of 1-100, the higher the food’s nutritional value, the higher the rating.

A recipe for success, it has become a reality in a number of major US shopping chains, where size matters and there can be up to 45,000 products on sale in each shop.
