 This study examined the legitimacy of the Nutriscore, a front-of-package nutrition label used in France and several other European countries, in Italy. It found that the legitimacy of the Nutriscore was primarily challenged from a pragmatic perspective, as it was seen as a threat to the Italian way of life and traditional food products. Additionally, the legitimacy of the Nutriscore was also challenged from a normative perspective, as it was perceived as not respecting the principles of the Mediterranean diet. Finally, the legitimacy of the Nutriscore was also challenged from a cognitive perspective, as it was seen as confusing for consumers due to its complexity.
