Abstract

In order to contribute to debates about Front-Of-Pack (FOP) nutrition labeling efficacy in improving consumers' dietary behavior, a lab experiment was conducted in France to evaluate the role of the Nutri-score system for breakfast cereals. Results show that the impact of the Nutri-score appearance is significantly higher when additional explanations are provided to consumers. Moreover, Nutri-Score improves consumers' Willingness-To-Pay (WTP) for healthy products (and reciprocally, reduces consumers' WTP for unhealthy products). The impact of the positive information on WTP is stronger for private label brands offered by supermarkets compared to national brands, and vice versa for negative effects.
