The U.S. food and beverage industry recently released a new front-of-package nutrition labeling system called “Facts Up Front” that will be used on thousands of food products. This article discusses the results of a randomized controlled study to test consumer understanding of the Facts Up Front system compared to the Multiple Traffic Light system. The findings from the study suggest that although both the Facts Up Front and Traffic Light systems can improve the accuracy of certain judgments of the nutritional quality of foods and beverages, a Traffic Light system that included High/Med/Low text and information about fiber and protein led to more accurate judgments of nutritional quality.
