Front-of-Package Nutrition Rating Systems and Symbols

"Growing recognition of the nation's obesity crisis and the prevalence of chronic disease have led to an array of efforts aimed at increasing physical activity and promoting healthful eating, including changes in the formulation, packing, labeling, and marketing of food and beverages products the contribute to a healthy lifestyle. In particular, the use of symbols summarizing key nutritional aspects and characteristics of food products has seen substantial growth."--Publisher's description.
