Purpose

Spain decided to implement NutriScore with the objective of helping consumers to choose healthier foods. NutriScore is a summary indicator interpretative nutritional labelling. This study aims to verify whether the coexistence with other interpretative labelling may influence NutriScore effectiveness.

Design/methodology/approach

A questionnaire was used to analyse two different brands in the same category; one of them ranked with a “B” NutriScore rating and the other with a “D” NutriScore rating. The product packaging was shown in four different ways: without indications, with nutrient-specific labels, with summary indicators (NutriScore) and with both interpretative indicators. Having positive and negative evaluations of NutriScore allowed us to assess its impact. Structural equation modelling (SEM), Student t-test and F-test were employed with a sample of 301 questionnaires.

Findings

The different formats of the interpretative labels did not moderate the relationship between perceived healthiness and purchase intention. When a food product is given positive evaluation from NutriScore, nutrient-specific interpretative labelling reinforces the effect of NutriScore. When a food product is given negative evaluation from NutriScore, nutrient specific interpretative labelling cancels the effect of NutriScore on perceived healthiness and purchase intention.

Originality/value

Previous studies have analysed the interaction between NutriScore and nutrient-specific interpretative labels, but they attribute a negative message to the product (warning labels). This study was aimed at analysing the interaction between NutriScore and summary indicators nutrient specific with positive message about the nutritional quality of the food item.

营养性标签和解释性食品标签的购买意向与消费者的信念和决定的相互作用

目的

西班牙决定实施NutriScore，以帮助消费者选择更健康的食品。NutriScore是摘要指标解释性营养标签。本研究旨在验证与其他解释性标签的共存是否会影响NutriScore的有效性。

设计/方法/方法

问卷用于分析同一类别中的两个不同品牌；其中一个被评为NutriScore评级为“ B”，另一个被NutriScore评级为“ D”。产品包装以四种不同的方式显示：无指示，带有营养成分标签，带有摘要指示符（NutriScore）和两个解释性指示符。对NutriScore进行正面和负面的评估，使我们能够评估其影响。结构方程模型（SEM），Student t检验和F检验与301份问卷的样本一起使用。

发现

解释性标签的不同格式并不能缓解感知的健康状况和购买意愿之间的关系。当食品被NutriScore给予正面评价时，营养成分特定的解释性标签会增强NutriScore的效果。当食品被NutriScore给予否定评估时，营养成分特定的解释性标签会抵消NutriScore对感知的健康和购买意愿的影响。

创意/价值

先前的研究已经分析了NutriScore和营养成分特定的解释性标签之间的相互作用，但他们将负面信息归因于产品（警告标签）。这项研究旨在分析NutriScore和特定营养素摘要指标之间的相互作用，并提供有关食品营养质量的正面信息。
