In Italy, discussions are currently ongoing to implement a front-of-pack nutrition label (FoPL) while a growing number of European countries are adopting the Nutri-Score. The effectiveness of the Nutri-Score among Italian consumers requires further investigation. This study compared five FoPLs among Italian participants (Health Star Rating system, multiple traffic lights, Nutri-Score, reference intakes, warning symbol) in terms of food choices and understanding of the labels by consumers. In 2019, 1032 Italian consumers completed an online survey in which they were asked to select one product they would likely purchase from a set of three foods with different nutrient profiles and then classify the products within the set according to their nutritional quality, first with no label and then with one of the five FoPLs on the pack. While no significant difference across labels was observed for food choices, the Nutri-Score demonstrated the highest overall performance in helping consumers to correctly rank the products according to their nutritional quality compared to the reference intakes (OR = 2.18 (1.50-3.17), -value < 0.0001). Our results provide new insights on the effectiveness of the Nutri-Score, which would be a relevant tool to inform Italian consumers on the nutritional quality of food products.
在意大利，目前正在讨论实施一种包装正面营养标签（FoPL），而越来越多的欧洲国家正在采用 Nutri-Score。Nutri-Score 对意大利消费者的有效性需要进一步研究。本研究比较了意大利参与者的五种 FoPL（健康星级评分系统、多个红绿灯、Nutri-Score、参考摄入量、警告符号）在消费者的食品选择和标签理解方面的效果。2019 年，1032 名意大利消费者完成了一项在线调查，要求他们从一组三种具有不同营养特征的食品中选择一种他们可能购买的产品，然后根据营养质量对产品进行分类，首先是没有标签，然后是包装上的五种 FoPL 之一。虽然在食品选择方面没有观察到标签之间的显著差异，但 Nutri-Score 在帮助消费者根据营养质量正确对产品进行排名方面的表现优于参考摄入量（OR=2.18（1.50-3.17），p<0.0001）。我们的研究结果提供了关于 Nutri-Score 有效性的新见解，这将是一种向意大利消费者提供食品营养质量信息的相关工具。
