Simplified nutritional-labeling systems provide single indicators of nutritional quality. Four studies compared two nutrition-labeling systems varying in complexity. A more subtle system (traffic-light with five colors instead of three) increases healthy choice and purchase. The 5-color system facilitates nutritional information processing and this influences healthiness perception of food products.
