BackgroundThe 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.PurposeTo test consumer understanding of the Facts Up Front system (Facts Up Front) compared to the Multiple Traffic Light system (Traffic Light). Facts Up Front displays grams/milligrams and percentage daily value information for various nutrients; Traffic Light uses an interpretive color-coded scheme to alert consumers to low, medium, and high levels of certain nutrients.DesignParticipants in an Internet-based study were randomized to one of five front-of-package label conditions: (1) no label; (2) Traffic Light; (3) Traffic Light plus information about protein and fiber (Traffic Light+); (4) Facts Up Front; or (5) Facts Up Front plus information about "nutrients to encourage" (Facts Up Front+).Setting/ParticipantsA total of 703 adults recruited through an online database in May 2011 participated in this study, and data were analyzed in June 2011.Main Outcome MeasuresTotal percentage correct quiz scores were generated reflecting participants' ability to compare two foods on nutrient levels, based on their labels, and to estimate amounts of saturated fat, sugar, sodium, fiber and protein in the foods.ResultsThe front-of-package label groups outperformed the control group on nearly all of the nutrient quizzes (p<0.05). The control group did not differ from the Facts Up Front group on the saturated fat quiz, or from the Facts Up Front+ group on the sugars quiz. Those in the Traffic Light+ group had the best overall performance (>80% on all quizzes).ConclusionsOverall, those in the Traffic Light+ condition performed better than those in the Facts Up Front conditions on measures of nutrition knowledge and label perceptions.Trial RegistrationThis study is registered at clinicaltrials.gov NCT01626729.Copyright © 2012 American Journal of Preventive Medicine.
