Effects of front-of-package nutrition labelling systems on objective understanding and purchase intention in Panama: results from a multi-arm parallel-group randomised controlled trial.

OBJECTIVE: To assess the effect of different front-of-package labelling (FOPL) schemes on the objective understanding of the nutritional content and intention to purchase products, in Panama. DESIGN: Single-blinded multi-arm parallel-group randomised controlled trial. SETTING: Supermarkets across Panama. Participants were exposed to two-dimensional images of fifteen mock-up products presented at random and balanced orders. Participants assigned to the intervention groups were exposed to mock-ups featuring one FOPL scheme: black octagonal warning labels (OWL), traffic-light labelling (TFL) or guideline daily amounts (GDA). The control group was not exposed to any FOPL scheme. PARTICIPANTS: Adult supermarket shoppers (n 1200). Participants were blinded to group assignment. RESULTS: A similar number of participants were randomised and analysed in each group: OWL (n 300), TFL (n 300), GDA (n 300) and control (n 300). The odds of choosing to purchase the least harmful or none of the options more often was the highest in the OWL group. Compared with the control group, these odds were two times higher in the OWL group (OR 2·13, 95 % CI 1·60, 2·84) and 57 % higher in the TFL (1·57, 1·40-2·56), with no changes in the GDA (0·97, 0·73-1·29). OWL also resulted in the highest odds for correctly identifying the least harmful option and for correctly identifying a product with excessive amounts of sugars, sodium and/or saturated fats. CONCLUSIONS: OWL performed best in helping shoppers to correctly identify when a product contained excessive amounts of nutrients of concern, to correctly identify the least harmful option and to decide to purchase the least harmful or none of the options, more often.

Market-driven fortification of vitamins and minerals in packaged foods targeted at children in Brazil.

This study aimed to characterise the market-driven fortification of vitamins and minerals in packaged foods targeted at children in Brazil. We analysed 535 food labels using data collected in a census-type method (n = 5620) of food labels in a Brazilian supermarket in 2013. Micronutrients declared in nutrition claims and the ingredients list (synthetic compounds) were considered to be added for commercial purposes. Analysis of the ingredients list and nutrition claims showed that market-driven fortification of vitamins and minerals was present in 27.1% of foods. The main vitamins and minerals were vitamins A, B complex, C, D, calcium, iron and zinc. The food groups 'Milk and dairy products' and 'Sugars, sugary foods and snacks' had the highest frequencies of micronutrients declared in the ingredients list. Calcium, iron, phosphorus, zinc and all vitamins, except B7, were found to be added for commercial purposes. Micronutrients were found to be commonly added to packaged foods as a marketing strategy directed at parents and their children. Future studies should assess the amount of vitamins and minerals added to packaged foods targeted at children and whether intakes of vitamins and minerals in children are potentially excessive.

Is the List of Ingredients a Source of Nutrition and Health Information in Food Labeling? A Scoping Review.

Nutrition labelling is any description intended to inform consumers about the nutritional properties of a food product and has focused primarily on nutrients. However, literature has shown that the nutritional quality of packaged foods is not limited to the amount of nutrients, considering that individuals do not consume only nutrients separately, but rather the entire food matrix. Therefore, to analyze the nutritional quality of a packaged food, it is necessary to read its ingredients. This scoping review aims to discuss (1) the list of ingredients as a source of health and nutrition information in food labelling; (2) opportunities to improve the nutrition labeling policies around the world. The study was carried out through a systematic search on Codex Alimentarius meeting reports. Results show that the list of ingredients is used as a source of nutritional and health information on food labelling; however, this label item is not considered in the regulatory field as a nutrition labelling requirement. It is suggested that nutrition labelling be discussed as a tool for food choices in the context of public health from a broader, consistent, convergent perspective, considering the list of ingredients as an item of nutrition labelling requirement to be included in public policies around the world.

Use of nutritional warning labels at the point of purchase: An exploratory study using self-reported measures and eye-tracking.

Nutritional warning labels are gaining relevance in the region of the Americas as a policy tool to reduce information asymmetry and encourage healthier food choices. However, empirical evidence about consumer experiences with warning labels after implementation is still scarce. In this context, the aim of the present work was to explore the use of nutritional warning labels after policy implementation in Uruguay, using a combination of eye-tracking and self-reported data. The study was conducted in three supermarkets, in two regional capitals, 19 months after the entry into force of the policy. A total of 224 participants were intercepted while entering the facilities of the supermarket and asked to wear a mobile eye-tracker while making their food purchases. Then, they were asked a series of questions about their awareness and use of warning labels. Although participants reported high awareness and understanding of the labels, active search and use at the point of purchase was low. Only 6% of the consumers declared having actively searched for the warning labels and 7% fixated their gaze on the labels. The majority of the participants (72%) who declared having seen the warnings on a product, purchased it anyway. However, 56% declared having changed their food choice decisions as a consequence of the implementation of the policy. Participants' accounts about reasons for (not) taking into account the warning labels provide relevant insights for the development of strategies to encourage citizens to increase policy effectiveness and encourage healthier food choices.

Children's reaction to sugar reduced dairy desserts in the context of the implementation of nutritional warning labels: An exploratory study.

The aim of the present work was to explore children's reaction to sugar reduction in the context of the implementation of nutritional warnings in Uruguay. The study was composed of two sessions involving three evaluation conditions: tasting without package information, package evaluation without tasting, and tasting with package information. A total of 122 children, ages ranging between 6 and 13 years old (47% girls) were involved in the study. In the first session, children's hedonic and emotional response to a regular and a sugar-reduced chocolate dairy dessert (without other sweeteners) was evaluated. In the second session, children first evaluated their expected liking, emotional associations and choice of packages differing in the presence of warning labels for excessive sugar content and cartoon character (2x2 design). Finally, they tasted the selected sample in the presence of the package and evaluated their liking, emotional associations, and intention to re-taste it. Although sugar reduction led to a significant reduction in overall liking, the dessert with 40% sugar reduction showed a mean overall score of 6.5 in a 9-point hedonic scale and was described using positive emoji (, , ). When the desserts were tasted with package information, no significant differences in the expected overall liking of the regular and sugar-reduced dessert were found. Regarding the effect of packaging elements, the presence of a warning label highlighting excessive content of sugar did not have a significant effect on children's choice. Instead, children's choices were defined by the presence of a cartoon character. Results from the present work provide additional evidence about the feasibility of reducing the sugar content and sweetness of dairy products targeted at children and stress the need to regulate the use of cartoon characters on products with an unfavorable nutritional profile. Methodological recommendations for sensory and consumer research with children are also discussed.

Qualitative menu labelling in university restaurants and its influence on food choices: A systematic review and synthesis without meta-analysis.

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.

Qualitative exploration of the reasons for not using nutritional warnings after policy implementation in Uruguay.

Nutritional warnings have gained popularity, particularly in the region of the Americas, to facilitate the identification of products with excessive content of nutrients associated with non-communicable diseases and encourage healthier food choices. Although warnings have been shown to be effective, an in-depth understanding of the reasons why some consumers do not use them is still lacking. The aim of the present work was to explore self-reported use of nutritional warnings and to identify the reasons for not considering nutritional warnings for making food purchase decisions after policy implementation in Uruguay. A non-probabilistic sample of 858 Uruguayan participants was recruited using an advertisement on Facebook and Instagram. Through an online survey, self-reported use of nutritional warnings was asked using a closed-open ended questions. Participants who reported not considering warnings to make their purchase decisions were asked to explain the reasons why using an open-ended question. Responses were analysed using deductive coding, based on the Behavioural Drivers Model. Thirty seven percent of the participants stated that the warnings had not influenced their purchase decisions. Motives for not being influenced by the warnings were related to lack of interest, attitudes, lack of perceived self-efficacy, cognitive biases and limited rationality when making purchase decisions. In addition, structural barriers, such as availability, cost and trust in the food industry also emerged from participants' responses. Strategies to encourage the use of warnings should include communication campaigns and policies to address structural barriers related to the perceived availability and affordability of healthy foods.

Analysis of the policy process for the implementation of nutritional warning labels in Uruguay.

OBJECTIVE: To analyse the process for the development and implementation of mandatory nutritional warning labels in Uruguay, in order to inform future nutrition policy making and strategic engagement by public health actors. DESIGN: The study design drew on policy analysis methodology and case study research methodology. Two main sources of information were selected and analysed for the current study: eighteen official documents from the Uruguayan government and 259 news reports, published between June 2017 and February 2021. SETTING: Uruguay, Latin America. RESULTS: The Uruguayan Ministry of Public Health led a cross-sectoral working group composed of diverse governmental stakeholders, international organisations and the academia to develop the front-of-package nutrition labelling policy. A robust evidence-based approach, based on rigorous scientific knowledge generated in the country, was followed. However, changes in the systemic governing coalition as a consequence of a change in government led to a delay in the entry into force and changes in the regulation. The food industry was the main opponent to the warning label regulation and relied on widely reported corporate political activities to influence the policy process: information and messaging, legal action, policy substitution, opposition, fragmentation and destabilisation. CONCLUSIONS: Key insights to inform future policy action in Uruguay and other jurisdictions were derived. Results stressed the importance of an evidence-based approach for policy design and the early engagement with actors from all the political system.

Communication Campaigns to Support the Use of Nutritional Warnings: Different Messages for Different People?

Communication campaigns are expected to contribute to increase the efficacy of nutritional warnings. In this context, the aims of the present work were (a) to evaluate how citizens perceive different types of messages for a communication campaign and (b) to determine if personal characteristics such as gender, age, and educational level, as well socioeconomic and nutritional status, moderate how citizens perceive such campaign messages. A series of graphic pieces were designed for each of the following three types of messages: promotion of informed food choices; raising awareness of the negative health consequences of excessive consumption of sugar, fat, and sodium; and promotion of healthy food choices. An online study was conducted with 774 participants, who were randomly assigned to one of the three types of messages. The participants' self-reported perception of the graphic pieces was evaluated using 7-point Likert-type scales. After completing the evaluation task, the participants proceeded to a series of choices. This was implemented to evaluate whether exposure to different types of messages affected hypothetical food choices. Results revealed that messages related to the promotion of healthy eating were perceived as the most adequate as part of a communication campaign and had the potential to encourage more healthful hypothetical choices in the experimental task. However, gender, age, and nutritional status moderated the influence of the type of message on the participants' perception, meaning that different groups perceived different types of messages as the most adequate. The results from the present work stress the need to include different types of messages in a communication campaign to target individuals with different motivations and characteristics.

Commercial foods for infants under the age of 36 months: an assessment of the availability and nutrient profile of ultra-processed foods.

OBJECTIVE: Considering the negative impact of the consumption of ultra-processed foods on health, the current study assessed the availability and nutritional profile of commercial ultra-processed foods for infants in Natal, Brazil. DESIGN: A cross-sectional exploratory study. SETTING: Foods targeted at children under the age of 36 months sold in retail establishments located in high- and low-income areas of the one capital city of Brazil. PARTICIPANTS: 1645 food products consisting of ninety-five different types of food were available. The foods were assessed according to the NOVA classification: minimally processed, processed and ultra-processed. The nutritional content per 100 g was assessed according to processing classification. RESULTS: Half of foods founded were breast milk substitutes and cereal foods (31·6 and 26·3 %, respectively). The foods were predominantly ultra-processed (79 %) and only 4·2 % were minimally processed, with similar proportions of ultra-processed foods being found in both high- and low-income areas. After excluding breast milk substitutes and follow-up formulas, all cereals, food supplements and some of the fruit or vegetable purees were ultra-processed, higher in energy density, fat, carbohydrate and protein and low in fibre (P < 0·05). CONCLUSIONS: The findings reveal that ultra-processed foods for infants are widely available in Brazil, reaffirming the need to strengthen the regulation of foods for infants and young children by introducing complementary measures designed to promote the production and marketing of foods manufactured using lower levels of processing.

Do nutritional warnings encourage healthier choices on food ordering websites? An exploratory experimental study in Uruguay.

OBJECTIVE: To evaluate if the inclusion of nutritional warnings in food ordering websites can discourage consumers from purchasing foods with excessive content of nutrients associated with non-communicable diseases (NCD). DESIGN: Participants were randomly assigned to one of the two experimental conditions: control (n 225) or nutritional warnings (n 222). Nutritional warnings corresponded to separate black octagonal signs containing the word 'Excess' followed by the corresponding nutrient: total fat, saturated fat, sugars and sodium. Participants were asked to purchase a lunch for themselves using a simulated food ordering website. SETTING: Online study in Uruguay. PARTICIPANTS: Convenience sample of 447 Uruguayan participants, recruited using social media. RESULTS: In the control condition, 76 % of the participants selected a dish or a beverage with excessive content of at least one nutrient in the simulated food ordering website. When nutritional warnings were included, this percentage significantly decreased to 62 % (P = 0·002). In addition, nutritional warnings caused a significant reduction in the percentage of participants who selected dishes with excessive content of total fat: 50 % v. 62 % (P = 0·012). CONCLUSIONS: Results from the present work provide preliminary evidence that the inclusion of nutritional warnings in food ordering websites could discourage consumers from selecting dishes and beverages with excessive content of nutrients associated with NCD.

Neoliberal discourse, actor power, and the politics of nutrition policy: A qualitative analysis of informal challenges to nutrition labelling regulations at the World Trade Organization, 2007-2019.

Unhealthy diets are increasing contributors to poor health and mortality in low- and middle-income countries (LMICs). Government interventions targeting the structural drivers of unhealthy diets are needed to prevent these illnesses, including nutrition labelling regulations that create healthier food environments. Yet, implementation remains slow and uneven. One explanation for slow implementation highlights the role of politics, including powerful ideological discourse and its strategic deployment by economically powerful actors. In this article, we advance research on the politics of nutrition policies by analysing political discourse on nutrition labelling regulations within an influential and under-studied global institution: the World Trade Organization (WTO). We identified WTO Technical Barriers to Trade (TBT) Committee meeting minutes with reference to nutrition labelling policies proposed by Thailand, Chile, Indonesia, Peru, Ecuador, Bolivia, and Uruguay (2007-2019; n = 47). We analysed the frames, narratives, and normative claims that feature in inter-country discourse within TBT meetings and examined how actors mobilize ideological and material sources of power via these statements. We find that informal government challenges to nutrition labelling proposals within the Committee featured a narrative that individualized the causes of and solutions to poor diet, downplayed harms from industrialised food products, and framed state regulation as harmful and unjust. These non-technical claims mobilised neoliberal ideology and rhetoric to contest the normative legitimacy of members' proposals and to de-socialize and de-politicize poor diets. Furthermore, high-income countries (HICs) re-framed policy goals to focus on individual determinants of poor nutrition whilst calling for their preferred policies to be adopted. Patterns of discourse within TBT meetings also had striking similarities with arguments raised by multi-national food corporations elsewhere. Our findings suggest that non-technical and ideological arguments raised during TBT meetings serve as inconspicuous tools through which nutrition labelling policies in LMICs are undermined by HICs, industry, and the powerful ideology of neoliberalism.

Immediate effects of the implementation of nutritional warnings in Uruguay: awareness, self-reported use and increased understanding.

OBJECTIVE: To assess the effects of nutritional warnings during the first month after the date of full compliance by the food industry in Uruguay in terms of citizen awareness, self-reported use and ability to understand nutritional information. DESIGN: The present work encompassed two online studies, conducted before (Study 1) and during the first month after the date of full compliance by the food industry (Study 2). An after-only design was used to assess awareness of the policy, exposure to nutritional warnings on food packages and self-reported use of warnings for making purchase decisions in Study 2. An after-only with control group experimental design was used to assess the effect of nutritional warnings on understanding of nutrition information in Studies 1 and 2. SETTING: Uruguay, one of the Latin American countries, that has recently implemented nutritional warnings. PARTICIPANTS: A non-probabilistic sample of 1772 participants was recruited using Facebook advertisements targeted at Uruguayan adult users. RESULTS: High awareness and self-reported use of nutritional warnings during the first month after the date of full compliance in Uruguay were observed. In addition, the before and after comparison showed that the implementation of warnings increased citizens' ability to use nutritional information to compare products and to identify products with excessive content of sugar, fat, saturated fat and sodium. CONCLUSIONS: The current study confirms results from experimental studies and provides additional evidence to support the implementation of nutritional warnings as one of the public policies that can contribute to tackle obesity and non-communicable diseases.

'I had never seen so many lobbyists': food industry political practices during the development of a new nutrition front-of-pack labelling system in Colombia.

OBJECTIVE: To identify and monitor food industry use of political practices during the adoption of nutrition warning labels (WL) in Colombia. DESIGN: Document analysis of publicly available information triangulated with interviews. SETTING: Colombia. PARTICIPANTS: Eighteen key informants from the government (n 2), academia (n 1), civil society (n 12), the media (n 2) and a former food industry employee (n 1). RESULTS: In Colombia, the food industry used experts and groups funded by large transnationals to promote its preferred front-of-pack nutrition labelling (FOPL) and discredit the proposed warning models. The industry criticised the proposed WL, discussing the negative impacts they would have on trade, the excessive costs required to implement them and the fact that consumers were responsible for making the right choices about what to eat. Food industry actors also interacted with the government and former members of large trade associations now in decision-making positions in the public sector. The Codex Alimentarius was also a platform through which the industry got access to decision-making and could influence the FOPL policy. CONCLUSIONS: In Colombia, the food industry used a broad range of political strategies that could have negatively influenced the FOPL policy process. Despite this influence, the mandatory use of WL was announced in February 2020. There is an urgent need to condemn such political practices as they still could prevent the implementation of other internationally recommended measures to improve population health in the country and abroad, nutrition WL being only of them.

Stars versus warnings: Comparison of the Australasian Health Star Rating nutrition labelling system with Chilean Warning Labels.

OBJECTIVE: The Health Star Rating (HSR) is a voluntary front-of-pack nutrition labelling system that rates products from ½ to 5 stars (five being healthiest). The Chilean Warning Label system displays warnings on foods high in sugar, saturated fat, sodium, or energy. We aimed to evaluate alignment between the systems. METHODS: New Zealand packaged products (n=13,868) were classified according to the two systems. Alignment was assessed by cross-checking the number of products meeting the criteria for warnings against star ratings. Products with no warnings but an HSR <2, or with >1 warning but an HSR of ≥3.5 were considered outliers. RESULTS: Two-thirds of products met the criteria for at least one warning. There was a significant positive relationship between the number of warnings and mean HSR: 0 warnings = HSR 3.77±.0166 (p<0.001), 1 warning = HSR 2.70±.0206 (p<0.001) and >1 warning = HSR 2.00±.0160 (p<0.001). The systems were non-aligned for 1,117 products (8%). CONCLUSION: HSR and the Chilean Warning Label systems are broadly aligned. Non-alignment is due to the Chilean system restricting warnings to foods containing added ingredients and HSR awarding points for positive components. Implications for public health: These results could be helpful in informing improvements to the HSR system.

How Can We Motivate People to Use Nutritional Warnings in Decision Making? Citizen Co-Created Insights for the Development of Communication Campaigns.

Nutritional warnings are intended to enable citizens to make informed choice by clearly identifying food products with excessive content of nutrients associated with noncommunicable diseases. The efficacy of this public policy is expected to improve if accompanied by communication campaigns that raise awareness of the existence of nutritional warnings, as well as encourage citizens to take them into account in decision making. Because ordinary citizens have been shown to generate significantly more creative and valuable ideas than advanced users and professional developers, the aim of the present work was to obtain qualitative, citizen co-created insights for the design of a communication campaign. An online study was conducted with 518 Uruguayan citizens, recruited using a Facebook advertisement. Participants were asked to answer a series of open-ended questions about how they would encourage other people to use the warnings for making their food choices, as well as the key contents of a communication campaign. Responses were analyzed using content analysis. Results showed that, according to the participants' accounts, an effective public awareness campaign aimed at promoting the use of nutritional warnings in decision making should include three main concepts: (a) position warnings as a cue to action for improving eating habits by enabling informed choices; (b) emphasize the benefits of using the warnings for avoiding consumption of unhealthy food and, consequently, achieving a healthier diet and an improvement in health status and quality of life; and (c) increase the perceived susceptibility and severity of the negative consequences of consumption of foods with excessive content of sugar, fat, and sodium. A communication campaign based on these key concepts could contribute to increasing the efficacy of nutritional warnings.

Are consumers willing to pay more for reformulated processed meat products in the context of the implementation of nutritional warnings? Case study with frankfurters in Chile.

The aim of the present work was to assess consumers' willingness to pay for reformulated frankfurters in the context of the implementation of nutritional warnings. Images of frankfurter packages were designed using a fractional factorial design with 5 2-level variables: brand type, sodium reduction, saturated fat reduction, fibre claim and cholesterol claim. An online study with 548 consumers was implemented with Chilean participants, who were asked to indicate how much they would be willing to pay for each of the packages. Data were analysed using analysis of variance and hierarchical cluster analysis. Willingness to pay was significantly affected by brand type and sodium and fat reduction, whereas fibre and cholesterol claim did not have a significant effect. These results suggest that in the context of the implementation of nutritional warnings reformulation of processed meat products should focus on the reduction of key nutrients, although consumers may not be willing to pay a higher price for reformulated products.

Use of added sugars in packaged foods sold in Brazil.

OBJECTIVE: Studies have shown that the consumption of added sugars may be associated with harmful health effects. The present study investigated the presence and types of added sugars in packaged foods. DESIGN: Cross-sectional analysis of the presence and types of added sugars in the ingredients lists of packaged foods sold in a major Brazilian supermarket. The nomenclature of ingredients classified as added sugars and their frequency were identified. Data were organised and analysed through descriptive statistics: absolute and relative frequencies of the presence of added sugars categorised by food groups were calculated, and ingredients were analysed by text mining using R statistical environment. SETTING: A supermarket in Florianópolis, a metropolis in southern Brazil. SUBJECTS: Packaged food products (n 4539) classified into eight groups. RESULTS: Of the 4539 products, 71 % had some type of added sugar. The group with the highest frequency of added sugars was 'products in which carbohydrates and fats are the main energy source' (93 %). Food groups containing predominantly salty foods had a high frequency of added sugars, such as 'meats and eggs' (61 %). In total, 179 different terms for added sugars were identified, of which sugar, maltodextrin and glucose syrup were the most frequent. CONCLUSIONS: Most of the packaged foods sold in Brazil contain added sugars, which may hamper adherence to the recommendation of limiting added sugars intake. The data may be useful for monitoring tendencies in the use of added sugars in packaged foods and as supplementary information to support the improvement of food label regulations.

Characterization of Breakfast Cereals Available in the Mexican Market: Sodium and Sugar Content.

Preschool Mexican children consume 7% of their total energy intake from processed breakfast cereals. This study characterized the nutritional quality and labelling (claims and Guideline Daily Amount (GDA)) of the packaged breakfast cereals available in the Mexican market. Photographs of all breakfast cereals available in the 9 main food retail chains in the country were taken. The nutrition quality of cereals was assessed using the United Kingdom Nutrient Profiling Model (UKNPM). Claims were classified using the International Network for Food and Obesity/non-communicable Diseases Research, Monitoring and Action Support (INFORMAS) taxonomy and the GDA was defined according to the Mexican regulation, NOM-051. Overall, a total of 371 different breakfast cereals were analysed. The nutritional profile showed that 68.7% were classified as "less healthy". GDAs and claims were displayed more frequently on the "less healthy" cereals. Breakfast cereals within the "less healthy" category had significantly higher content of energy, sugar and sodium (p < 0.001). Most of the claims were displayed in the "less healthy" cereals (n = 313). This study has shown that there is a lack of consistency between the labelling on the front of the pack and the nutritional quality of breakfast cereals.

Warnings as a directive front-of-pack nutrition labelling scheme: comparison with the Guideline Daily Amount and traffic-light systems.

OBJECTIVE: Warnings have recently been proposed as a new type of directive front-of-pack (FOP) nutrition labelling scheme to flag products with high content of key nutrients. In the present work, this system was compared with the two most common FOP nutrition labelling schemes (Guideline Daily Amounts (GDA) and traffic-light system) in terms of goal-directed attention, influence on perceived healthfulness and ability to differentiate between products. Design/Setting/Subjects Goal-directed attention to FOP labels was evaluated using a visual search task in which participants were presented with labels on a computer screen and were asked to indicate whether labels with high sodium content were present or absent. A survey with 387 participants was also carried out, in which the influence of FOP labels on perceived healthfulness and ability to identify the healthful alternative were evaluated. RESULTS: Warnings improved consumers' ability to correctly identify a product with high content of a key nutrient within a set of labels compared with GDA and received the highest goal-directed attention. In addition, products with high energy, saturated fat, sugar and/or sodium content that featured warnings on the label were perceived as less healthful than those featuring the GDA or traffic-light system. Warnings and the traffic-light system performed equally well in the identification of the most healthful product. CONCLUSIONS: Results from the present work suggest that warnings have potential as directive FOP nutrition labels to improve consumer ability to identify unhealthful products and highlight advantages compared with the traffic-light system.
