“…The authors reported that consumers easily relate green to the best option and red to the worst but yellow causes doubt. A similar finding was reported by León‐Flández et al (2015) who found that Spanish consumers had a low comprehension of the traffic light system. In a study conducted in Germany, Borgmeier and Westenhoefer (2009) observed that when the traffic light label is used in conjunction with other labels, consumers may find the excess information hard to use, in line with the results of this review.…”

Qualitative menu labelling can be defined as descriptive or non-numerical interpretive labels (e.g. traffic light labelling, healthy food symbols, messages or ingredient lists). Qualitative information seems to have a positive influence on consumers' food choices, particularly in institutional food service establishments, such as in universities. The aim of this systematic review was to assess the influence of different formats of qualitative menu labelling on food choices in university restaurants. This systematic review was guided by the Preferred Reported Items for Systematic Reviews and Meta-Analyses (PRISMA) and Synthesis Without Meta-Analysis (SWiM) and conducted vote counting of studies based on the direction of effect. Studies were retrieved from Cochrane Library, Scopus, MEDLINE, LILACS, SciELO and Web of Science databases and reference lists of selected articles. Experimental and quasi-experimental studies were included. Two independent researchers searched and extracted the data and assessed the methodological quality using the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies. From the initial search (460 records), four papers were selected, plus one paper identified in a previous study and a further six from an update search, totalling 11 included studies, reporting 14 different interventions (n = 499 174). Types of interventions included the use of symbols and the inclusion of traffic light labelling. Outcomes of interest were food choice, expressed as mean, median or percent healthy food choices or purchases. Qualitative menu labels increased healthy food choices and/or purchase behaviour, with 10 of 12 interventions favouring the intervention (83%; 95%CI 55-95%; p = 0.0386). Most of the studies favouring the intervention used healthy food symbols for healthier foods or food components, alone or in association with another intervention and were of moderate and weak quality. These findings may serve as a basis for the implementation of nutrition information policies in university restaurants.

“…In agreement with our results, a study in Spain showed based on subjective data that 41.4% of the participants knew about the NTLL, 61.5% of which stated that the NTLL seemed useful and 31.4% referring a usual use of it. In addition, the study also showed that 18.6% of the participants correctly understood the NTLL information [24].…”

Use, knowledge, and effectiveness of nutritional traffic light label in an urban population from Ecuador: a pilot study

et al. 2019

Background The nutritional traffic light label (NTLL) has become one of the most used Front of Package labels (FOP’s) around the world, for its simple and easy to understand graphical system. In Ecuador, this labelling system has recently been implemented; then, this research aims to evaluate the use and knowledge of NTLL and its effectiveness as a public health promotion strategy. Method In a cross-sectional study at two different urban supermarkets in Quito-Ecuador, a survey was conducted in 73 participants to inquire about knowledge, perspectives and purchasing habits regarding the NTLL. Objective data obtained from pictures of the participants’purchase was compared with subjective data obtained from the survey. For categorical variables, Chi square or Fisher’s Exact test were used and variables with a statistical significance at α = 0.1 were included in multivariate logistic regression models. Results 88.7% of participants knew about the NTTL. 27.4% reported using the NTLL, while 28.4% of participants were observed to really use it. Significant associations between self-knowledge of the NTLL and education level ( p = 0.007) or knowledge level ( p = 0.001) were found. A significant association was also found between the refered use of the NTLL and the shopping influencing factor ( p = 0.02). In the multivariate analysis an association between knowledge of the NTLL and observed use was found only when adjusted for the supermarket ( p = 0.038). Conclusion This study found that the level of knowledge of the NTLL in the studied population was relatively high; however, both the referred and the observed use of the NTLL were low. Use and knowledge of the NTLL were associated with the socioeconomic and educational status of the participants. Thus, the change in nutritional patterns needs additional strategies to put the NTLL before the brand once customers make their purchases.

PurposeThis study aimed to examine the perceptions and preferences of Brazilian adult consumers about four different front-of-pack (FOP) food labeling systems proposed by the Brazilian National Health Regulatory Agency.Design/methodology/approachThis is a qualitative study conducted with 33 participants allocated in six focus groups. Four different types of FOP labels were displayed on processed and packaged bread: three interpretive warning labels (black triangle, black octagon and red ellipse) and a hybrid model (nutritional traffic light). Thematic analysis was used to identify the key topics addressed by participants.FindingsThree topics were identified: label design, clarity and precision of information. The results demonstrated an influence of labels on product development and consumers' food choices. Most participants expressed a preference for black warning labels and reported the importance of statements endorsed by the Ministry of Health, which provide credibility and could influence food choices. Furthermore, participants agreed that the traffic light system provides more information but is difficult to interpret when comparing products. Warning labels were reported to have the greatest influence on purchase decisions. However, participants were concerned about how to understand the lack of warning labels on some products.Practical implicationsThe results may help and support the Brazilian Health Regulatory Agency to identify and recommend the most effective FOP labeling system to be adopted in Brazil.Originality/valueFew studies investigating adult consumers' perceptions of different FOP label formats have been conducted in the Brazilian context. Our study contributes to the small pool of evidence on the topic by demonstrating that FOP labels can be helpful for consumers when they are presented in an intuitive, interpretative and trustworthy format.
