OBJECTIVE: The US Food and Drug Administration and Institute of Medicine are currently investigating front-of-package (FOP) food labelling systems to provide science-based guidance to the food industry. The present paper reviews the literature on FOP labelling and supermarket shelf-labelling systems published or under review by February 2011 to inform current investigations and identify areas of future research. DESIGN: A structured search was undertaken of research studies on consumer use, understanding of, preference for, perception of and behaviours relating to FOP/shelf labelling published between January 2004 and February 2011. RESULTS: Twenty-eight studies from a structured search met inclusion criteria. Reviewed studies examined consumer preferences, understanding and use of different labelling systems as well as label impact on purchasing patterns and industry product reformulation. CONCLUSIONS: The findings indicate that the Multiple Traffic Light system has most consistently helped consumers identify healthier products; however, additional research on different labelling systems' abilities to influence consumer behaviour is needed.

    • "Utilizing this as a conceptual frame, a great deal of the research on FOPs has focused on the late stages of information processing, specifically, comprehension (Campos et al., 2011; Hawley et al., 2013). One common aspect of these studies is that participants are given the goal of evaluating the healthfulness of products. "

    ABSTRACT: Objectives: 1) To assess whether Front-of-Pack (FOP) nutrition labels garner attention more readily than more complete, mandated nutrition information (the Nutrition Facts Panel (NFP), required in the US), and 2) To determine whether label design characteristics, specifically, color coding and/or coding with facial icons, increase attention to the FOP label. Methods: In two experiments, we tracked the allocation of attention while participants (n=125) viewed novel and commercial packages with varied FOP designs using a change detection methodology. Results: We found empirical evidence that FOP labels are attended more often, and earlier, than the currently mandated NFP, and that this benefit is due both to its placement on the front of the package and to the design characteristics of the FOP. Specifically, the use of color in FOPs increased attention to the label, but there was no evidence that coding information via facial icons impacted attention. Conclusions: Our work supports a growing body of evidence supporting the use of FOP labels to attract attention to nutritional information. Findings may be relevant to inform policy decisions on labeling standards.

    • "In the realm of food packaging, one proposal that continues to receive attention around the world is the implementation of a TLC system to highlight the nutritional contents of food relative to recommended guidelines (Gorton, Mhurchu, Chen, & Dixon, 2009; Grunert & Wills, 2007). A series of recent review papers have found a generally positive impact of TLC systems as a simplified approach to food labeling that can help consumers' understand nutritional information (e.g., Grunert & Wills, 2007; Hawley et al., 2013; Hersey, Wohlgenant, Arsenault, Kosa, & Muth, 2013; Lobstein & Davies, 2009). Research also indicates that people prefer TLC systems that help them categorize food in terms of its health quality (Pettigrew, Pescud, & Donovan, 2011), are more effective at recognizing healthier foods with a TLC label (Borgmeier & Westenhoefer, 2009), and are more likely to avoid foods that TLC systems highlight in red (Balcombe, Fraser, & Falco, 2010).

    ABSTRACT: Government regulators and consumer packaged goods companies around the world struggle with methods to help consumers make better nutritional decisions. In this research we find that, depending on the consumer, a traffic light color-coding (TLC) approach to product labeling can have a substantial impact on perceptions of foods' health quality and food choice. Across 3 lab experiments and a field experiment, we find that TLC labels provide nondieters with an information processing cue that directly influences evaluations in a manner that is consistent with the "stop" and "go" logic behind the traffic light labels. In contrast, we find that dieters do not simply adopt the red, yellow, and green cues into their health quality evaluations. Instead, regardless of the color, the TLC approach increases the depth at which dieters process label information. Dieters tend to focus on the costs of consumption and, as a result, lower their health quality evaluations. In a field study, measuring actual behavior in a grocery store, health quality evaluations predicted consumption and consistent with the color coding of the labels nondieters consumed the most when they were presented with a predominantly green label.

    • "La littérature révèle de nombreux problèmes de compréhension et d'usage de l'information nutritionnelle [8] [9] par les consommateurs. Concernant les formats utilisés, plusieurs études montrent que la préférence déclarée n'est prédictive ni de la compréhension ni de l'utilisation [10]. De plus, la première étape indispensable, et sans doute majeure, pour qu'un logo soit efficace, quels que soient sa forme ou son contenu, est qu'il soit vu par le consommateur dans le contexte d'un magasin complexe et déjà chargé d'informations et de sollicitations diverses[11].

    ABSTRACT: La mise en place d’un système d’information nutritionnelle synthétique est envisagée pour orienter favorablement les achats alimentaires. Dans 2 supermarchés, pendant 10 semaines, pour 3 catégories (produits laitiers frais, plats cuisinés, snacking frais), les produits appartenant au meilleur tiers nutritionnel de leur catégorie ont été signalés par un logo positif, « le choix Vita+ », et ils ont bénéficié d’une campagne de communication in situ. L’analyse des achats des clients réguliers (clients porteurs de cartes de fidélité), enregistrés dans les 2 magasins tests et dans 2 magasins témoins, avant et pendant l’intervention, ainsi que l’année précédente, n’a mis en évidence aucun impact significatif de l’intervention sur les achats des produits signalés « le choix Vita+ ». Une étude qualitative a révélé le manque de visibilité de l’intervention face aux autres publicités et promotions, ainsi que l’incompréhension des clients face à un système d’information nutritionnelle, certes synthétique, mais partiel et par catégorie. L’étude souligne la difficulté d’évaluer l’impact de l’implantation d’un logo nutritionnel en conditions réelles, et donne quelques pistes sur les erreurs à ne pas commettre lors du développement d’un tel logo.
