Abstract
As nutrition scientists study and debate the causes of obesity and look to improve the quality of the American diet, there is a renewed interest in nutrition resources to help people make more healthful dietary choices at the grocery store. New, voluntary front-of-the-package nutrition labels on food products and new on-shelf labeling systems in grocery stores are emerging as viable tools to help lead consumers to more nutritious diets. Although more studies are needed to see which front-of-the-package or on-shelf labeling systems are most effective, it is clear that consumers and health professionals want easier and clearer ways to identify healthful food products for themselves and their families
