This study aimed to compare consumers' objec- tive understanding of five FoPLs [Health Star Rating system (HSR), Multiple Traffic Lights (MTL), Nutri-Score, Reference Intakes (RIs), Warning Symbol] in Mexico.
1 001 Mexican consumers were recruited and asked to rank three sets of label-free products according to their nutritional quality, via a survey. Upon completion of this task, participants were randomized to one of five FoPL condi- tions and were again asked to rank the same sets of products, this time with a FoPL displayed on pack. Change in ability to correctly rank products across the two tasks was assessed by FoPL using ordinal logistic regression.
Nutri-Score and MTL performed best, followed Warning Symbol, HSR and RIs.
Nutri-Score and MTL appear as efficient schemes to inform consumers on the nutritional quality of foods, in particular in Mexico, where it would be a helpful tool for consumers in purchasing situations.
本研究旨在比较墨西哥消费者对五种营养成分标签[健康星级评定系统（HSR）、多重红绿灯标识（MTL）、营养评分、参考摄入量（RIs）、警示标志]的客观理解。
招募1001名墨西哥消费者，通过一项调查要求他们根据营养质量对三组无标签产品进行排序。完成此任务后，参与者被随机分配到五种营养成分标签条件之一，再次要求他们对同一组产品进行排序，这次包装上显示了营养成分标签。通过使用有序逻辑回归的营养成分标签评估两项任务中正确对产品进行排序的能力变化。
营养评分和多重红绿灯标识表现最佳，其次是警示标志、健康星级评定系统和参考摄入量。
营养评分和多重红绿灯标识似乎是向消费者告知食品营养质量的有效方案，特别是在墨西哥，这对消费者在购买时将是一个有用的工具。
