Respondents from Argentina, Australia, Bulgaria, Canada, Denmark, France, Germany,Mexico, Singapore, Spain, the United Kingdom, and the United States took part in the Front-of-Pack International Comparative Experiment between April and July 2018. Respondents were shown foods of varying nutritional quality (with no label on package) and selected which they would be most likely to purchase. The same choice sets were then shown again with 1 of 5 randomly allocated labels on package (Health Star Rating (HSR), Multiple Traffic Lights (MTL), Nutri-Score, Reference Intakes, or Warning Label). We calculated an improvement score (from 11 100 valid responses) to identify the extent to which the labels produced healthier choices.Results. The most effective labels were the Nutri-Score and the MTL (mean improvement score = 0.09; 95% confidence interval [CI] = 0.07, 0.11), then the Warning Label (0.06; 95% CI = 0.04, 0.08), the HSR (0.05; 95% CI = 0.03, 0.07), and lastly the Reference Intakes (0.04; 95% CI = 0.02, 0.04).Conclusions. Well-designed, salient, and intuitive front-of-package labels can be effective on a global scale. Their impact is not bound to the country from which they originate.
