Performance of the Nutri-Score and Warning Labels in Identifying the Healthier Product

Abstract

Different types of Front-of-Package (FOP) have been designed around the world to help consumers assess the healthiness of foods and promote healthier options. An online study was conducted with Mexican and Spanish consumers to compare the current Mexican warning labeling system and the European Nutri-Score, which has been adopted by Spain and other European countries. 156 participants were asked to choose between 30 pairwise comparisons. When employing the British FSA/Ofcom nutrient profile score to measure product healthiness, the Warning Label System provided the most accurate results in determining the healthier of two yogurt brands in comparison to the Nutri-Score and the control condition.
