RESUMEN
Recent empirical evidence suggests that gut dysbiosis is one of the negative health outcomes potentially associated with chronic consumption of some food additives. In this context, the present study aimed at analyzing the disclosure of food additives associated with gut dysbiosis in the labels of products commercialized in the Uruguayan market. A cross-sectional survey of packaged products commercialized in nine supermarkets was conducted between August and September 2021. All packaged processed and ultra-processed products available in each data collection site were surveyed using a cellphone app. The information available on the labels was manually extracted and the disclosure of food additives was analyzed using a computer assisted approach. Results showed that 38.1% of the products disclosed at least one food additive associated with gut dysbiosis. Disclosure was most frequent in ice-cream and popsicles, beverages, meat products and analogues, desserts, and fats, oils and fat and oil emulsions. Potassium sorbate was the individual additive associated with gut dysbiosis most frequently disclosed on the labels, followed by mono- and di-glycerides of fatty acid, sucralose, carboxymethylcellulose, acesulphame potassium, carrageenan, and sodium benzoate. These food additives frequently co-occurred and network analysis enabled the identification of patterns of co-occurrence. Taken together, results from the present work suggest the need to conduct additional research to assess the intake of food additives associated with gut dysbiosis at the population level, as well as to evaluate potential synergistic effects of food additives.

OBJECTIVE: To explore the perception and experiences of parents of children and adolescents during the first year of the mandatory implementation of nutritional warning labels in Uruguay. DESIGN: Qualitative research based on semistructured interviews. SETTING: Montevideo, Uruguay. PARTICIPANTS: Twenty-eight parents of children and adolescents. PHENOMENON OF INTEREST: Perception of and experiences with warning labels, a front-of-pack nutrition labeling scheme that has become increasingly popular in Latin America. ANALYSIS: Content analysis of the transcripts based on a deductive-inductive approach. RESULTS: Interview transcripts evidenced high awareness, acceptance, and understanding of warning labels among parents of children and adolescents. Most participants reported considering warnings for decision making and changing their purchase decisions because of their implementation, particularly when choosing foods for their children. They reported their children were aware of and understood warnings but did not tend to take them into account when choosing foods. CONCLUSIONS AND IMPLICATIONS: Results from the present work contribute to the growing body of literature showing the effectiveness of warning labels. Lack of interest or perceived benefits and structural barriers emerged as key motives for not using the warnings when making purchasing decisions, suggesting the need to develop additional strategies to increase policy effectiveness.

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.

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.

The information included on food packages has a crucial role in influencing consumer product associations and purchase decisions. In particular, visual and textual cues on processed and ultra-processed products can convey health-related associations that influence consumer healthiness perception and purchase decisions. In this context, the present work aimed to explore the use of health-related cues on the packages of processed and ultra-processed products sold in Uruguay to provide insights for policy making. A total of 3813 products from thirty-four different food categories found in four of the most important supermarket chains in Uruguay were surveyed. The textual and visual information included on the packages as well as the nutritional composition of the products were analysed. Results showed that 67 % of the products included at least one health-related cue. Pictures of culinary ingredients, natural and minimally processed foods were the most frequent health-related cue, followed by references to naturalness and claims related to critical nutrients. The prevalence of health-related cues largely differed across product categories, ranging from 100 to 17 %. The relationship between the presence of health-related cues on the packages and the excessive content of nutrients associated with non-communicable diseases was assessed using a gradient boosting model, which showed limited predictive ability. This suggests that the inclusion of health-related cues on food packages was not strongly related to the nutritional composition of products and therefore cannot be regarded as a healthiness indicator. These results stress the need to develop stricter labelling regulations to protect consumers from misleading information.

Abstract: Food donation has expanded globally and has become a common form of food assistance in emerging countries. However, research on food donation experiences in these settings is still scarce. Purpose: In this context, the objectives of the present work were as follows: (i) to explore the views of Uruguayan stakeholders on food donation as a strategy to reduce food waste, (ii) to identify barriers and enablers for food donation in Uruguay, and (iii) to explore the organizational characteristics of Uruguayan food banks. Methods: A qualitative approach based on two data collection strategies was used: documentary content analysis of official governmental documents and in-depth semi-structured interviews with key stakeholders related to food waste and food donations in Uruguay. Results: Food donation emerged as a central strategy for food waste reduction in the view of Uruguayan stakeholders, mainly because it was perceived as an efficient strategy to reduce food insecurity. The complexity of food donation was acknowledged by Uruguayan stakeholders and who identified several barriers for its implementation related to economic considerations, the characteristics of the donated products, legal and commercial considerations, and organizational characteristics of food banks. Conclusion: Although most barriers were aligned with results from previous studies conducted in developed countries, some specificities to the Uruguayan context were also identified. Clear and detailed legal frameworks to ensure that the donated products reach the target population along with nutritional requirements for the foods to be donated were deemed necessary.
RESUMEN
ABSTRACT The present work aimed to assess Uruguayan consumers support of the inclusion of nutritional warnings on four types of retail food establishments and to obtain consumer insights on how the warnings could be implemented in such establishments. For this purpose, an online survey was conducted with a non-probabilistic sample of 547 participants recruited via an advertisement on social media. Participants were requested to indicate their degree of agreement with the implementation of nutritional warnings in bakeries, delicatessens, fast-food restaurants and while ordering food online, and to provide ideas on how to include this information for each establishment. Results suggested that the inclusion of nutritional warnings in retail food establishments was positively perceived by participants. Participants highlighted that warnings should be highly visible to customers while making purchase decisions, so they become a relevant cue for making food choices. In particular, the retail display case and menu boards were identified as key locations for warnings in bakeries, delicatessen, and fast food restaurants, respectively. These results contribute valuable insights on how to implement the extension of nutritional warnings to unpackaged foods or foods made and packaged at the point of purchase.
RESUMEN El presente trabajo tuvo como objetivo evaluar la percepción de los consumidores uruguayos en relación a la implementación de advertencias nutricionales en cuatro puntos de venta de comida y generar ideas sobre cómo podría implementarse esta medida. Se realizó un estudio online con una muestra no probabilística de 547 participantes, reclutados utilizando publicidad en redes sociales. Los participantes indicaron su grado de acuerdo con la implementación de advertencias nutricionales en panaderías, rotiserías, lugares de venta de comida rápida y sitios de pedidos online, y proporcionaron ideas sobre cómo incluir esta inforamción en cada punto de venta. Los resultados sugieren que la población tiene una perecpeción positiva sobre la inclusión de advertencias nutricionales en puntos de venta de comida. Los participantes destacaron la importancia de incluir esta información en un lugar visible al momento de elegir los productos, de forma que pueda ser tenida en cuenta al tomar las decisiones. En particular, las vitrinas y la cartelería/pizarras fueron identificados como lugares estatégicos para la inclusión de advertencias nutricionales en panaderías/rotiserías y puntos de venta de comida rápida, respectivamente. Los resultados proporcionan valiosa información para extender la inclusión de advertencias nutricionales a puntos de venta de comida.
RESUMEN
Significant reductions in household food waste have been regarded as a key step towards achieving global sustainable development. Household food waste is a complex phenomenon determined by consumer behavior along the steps of the "food journey" that goes from purchasing to final disposal. Although avoiding food waste is socially desirable and raises positive attitudes, consumers do not frequently engage in avoidance behaviors. The objectives of the present work were: i) to explore the views of Uruguayan citizens on household food waste, and ii) to identify drivers of food waste among Uruguayan households. A total of 20 in-depth interviews based on a semi-structured guide were conducted by telephone. Participants were asked to recall and describe the last time they discarded food, as well as to describe the most common food waste situations in their household, the most commonly used strategies to avoid food waste and how they could reduce it. The transcripts were analyzed using content analysis based on a deductive-inductive approach. Interviews revealed that most of the participants perceived food waste in their homes as null or low, whereas food waste in the country was regarded as high. When participants described food waste incidents, they perceived it as 'unavoidable', suggesting that they tended to find a rational explanation outside of their will to justify their behavior. Participants' discourses enabled the identification of drivers related to behavioral factors, personal factors, product factors, and contextual factors. Results stress that most promising entry points for communication campaigns and intervention programs to reduce household food waste should focus on behavioral factors, planning throughout all the household stages of the food journey and the provision of knowledge and skills on food storage, handling, and preparation.

ABSTRACT The aim of the present work was to explore the influence of consumer characteristics on purchase decisions when facing products with nutritional warnings a few days after their implementation in Uruguay. A non-probabilistic sample of 917 participants was obtained using an advertisement on social media. Participants were asked if they had seen the warning signs when making their food purchases and if they had seen the warnings on any product they intended to buy. Participants who answered affirmately (n= 616) were asked about their purchase decision by answering the question "What have you done with the product?" using the following response options: 'I purchased it anyway', 'I purchased a similar product with fewer excess signs', 'I purchased a similar product without excess signs', 'I didn't purchase the product or any similar one'. Univariate and multivariate multinomial logistic regression models were used to explore the influence of individual variables on participants' likelihood of having taken different decisions when facing a product with warnings. Results showed that participants older than 55 years were more likely to react to the warnings by purchasing a similar product with fewer warnings or by not purchasing any product. Likelihood of modifying purchase decisions due to the inclusion of the warnings was associated with a frequent consumption of natural and minimally processed foods and a low consumption frequency of ultra-processed products. These results provide insights to target efforts to promote the use of nutritional warnings in decision making.
RESUMEN El objetivo del presente trabajo fue explorar la influencia de caraterísticas de los consumidores en sus decisiones de compra al enfrentar productos con advertencias nutricionales, unos días después de su implementación en Uruguay. Se obtuvo una muestra no probabilística de 917 participantes utilizando redes sociales. Se les preguntó a los participantes si habían visto las advertencias en un producto que tenían la intención de comprar. A los participantes que respondieron afirmativamente (n= 616) se les pidió qué indicarn qué habían hecho con el producto, utilizando las siguientes opciones de respuesta: 'Lo compré igual', 'Compré un producto similar con menos símbolos de exceso', 'Compré un producto similar sín símbolos de exceso' y 'No compré el producto ni tampoco otro similar. Los datos se analizaron utilizaron modelos de regresión multinomial univariados y multivariados. Los participantes mayores de 55 años presentaron una mayor probabilidad de reaccionar a las advertencias no comprando el producto. La probabilidad de modificar la decisión de compra debido a las advertencias estuvo asociada con una mayor frecuencia de consumo de alimentos naturales y mínimamente procesados y una menor frecuencia de consumo de productos ultra-procesados. Los resultados del presente trabajo sugieren que los esfuerzos para promover el uso de las advertencias en la toma de decisiones deben estar focalizados en los ciudadanos con el mayor consumo de productos ultra-procesados.
RESUMEN
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.

OBJECTIVE: The information displayed on the packages of feeding bottles and teats commercialised in Montevideo (Uruguay) was analysed using content analysis with the goal of identifying key marketing practices that may discourage breast-feeding. DESIGN: The study was conducted as part of the periodic assessment performed by the Uruguayan government to monitor the marketing of breast milk substitutes. All the feeding bottles and teats sold in forty-four retail outlets selling breast milk substitutes were purchased. The information available on the packages was analysed using content analysis and descriptive statistics. SETTING: Montevideo, Uruguay. RESULTS: A total of 197 feeding bottles and 71 teats were found. The majority of the packages included information to enable caregivers to adequately use the products, including recommended age, instructions on how to use the products and instructions on the use of hygienic practices. However, the packages frequently included information that implied that bottle feeding was equivalent to breast-feeding, particularly from a physiological perspective, or that idealised product use. Idealisations included ability to reduce colic, improvements in the feeding experience and improvements in children's health, well-being and development. Statements on the superiority of breast-feeding were infrequent. CONCLUSIONS: The results from the present work showed the high prevalence of marketing practices on the packages of feeding bottles and teats that may discourage breast-feeding. Stricter and more detailed regulations seem necessary to enable caregivers to make informed feeding decisions for infants.

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.

Human rabies, a neglected viral zoonosis, is preventable through domestic animals vaccination and post-exposure prophylaxis using inactivated rabies vaccines. During vaccine production, several mandatory in vivo quality control trials, such as potency, live virus, and safety, are responsible for the use of large numbers of laboratory animals. Over the years, global organizations encouraged the development of alternative methods to reduce, replace and refine the use of animals in the pharmaceutical industry. In this study we standardized an in vitro assay for determination of residual live virus combining viral isolation techniques with direct immunofluorescence detection and viral quantification by a molecular method. Standardization of viral recovery steps and quantification by RT-qPCR were performed and the combined method was shown to be 3 fold more sensitive than the in vivo assay. It was possible to identify viral suspensions cultures, which still had residual viable rabies virus particles, evidencing the importance to implement this method in quality control schemes of rabies vaccine production. In addition, this developed assay is more practical, inexpensive and less time consuming, producing results in just 4 days, which may allow greater agility in the internal quality control of the vaccine. The in vitro method may reduce 2/3rd of laboratory animals numbers used for this purpose, since it can be applied in the intermediate quality control of inactivated rabies vaccine production.

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.

The inclusion of sodium warnings on food packages has been proposed as a means to encourage population to reduce sodium intake. However, consumers who focus on today rather than tomorrow or consumers who downplay or underestimate risks might pay little attention to warnings. The aim of the present study was to explore whether time orientation and perceived risk of sodium consumption may moderate the influence of sodium warnings on food choices. An online study involving 498 Uruguayan participants was carried out. Participants evaluated pairs of bread packages differing in three 2-level variables (sodium warning, type of bread and brand) and were asked to indicate the one they would choose if they were in a supermarket. Then, they answered a scale on 'consideration of future consequences' adapted to eating habits, and responded to statements measuring perceived risk of sodium consumption. Results revealed that sodium warnings had a significant effect on participants' choices. However, the efficacy of warnings was moderated by time orientation and risk perception. A focus on immediate consequences and thinking that the risk associated with sodium consumption can be compensated, decreased the efficacy of the sodium warning. These results provide experimental evidence of the potential of warnings to discourage consumption of products with high sodium content and suggest that communication campaigns accompanying the introduction of warnings should promote a future-oriented vision on eating habits, raise risk awareness and stress that the risks are not easily compensated.

Phenolic compounds play a major role in the intensity and characteristics of wine astringency. However, studies involving commercial wine samples are still scarce. The aim of the present work was to study the relationship between astringency and phenolic composition of commercial Uruguayan Tannat wines using boosted regression trees (BRT), a novel predictive method. Forty commercial Tannat wines were evaluated by a trained sensory panel (9 members), who assessed their total astringency intensity using time-intensity (TI) and described their astringency sub-qualities using a check-all-that-apply (CATA) question composed of sixteen terms. The polyphenolic profiles of the wines were determined by HPLC-MS and conventional oenological parameters were also obtained. Fifty BRT models with different partitions of the data in training and test sets were built for astringency maximum intensity (Imax) and for the frequency of use of the 16 astringency sub-qualities considered in the CATA question. As predictor variables, 84 phenolic compounds and oenological parameters were considered for all BRT models. Both strong and weak predictive models were obtained for each response variable. Predictive accuracy was much higher for astringency intensity than for the frequency of mention of astringency sub-qualities. Still, the BRT models allowed to point out to some compositional variables most likely involved in wine astringency perception. Total tannin concentration (chemically determined) was the most relevant explanatory variable for sensory astringency, while flavan-3-ols were the individual phenolic compounds with the highest contribution to astringency, particularly some dimers, trimers and the sum of non-galloylated tetramers. However, the effect of these predictors differed according to the astringency sub-quality considered as response. As expected, non-linear relationships between phenolic compounds and astringency were found. These results contribute to the understanding of the influence of phenolic composition on wine astringency and stress the potential of BRT models for identifying the compounds responsible for this complex sensory characteristic.

OBJECTIVE: To evaluate how information about low nutrient content included in the traffic light labeling system influences consumers' perception of the healthfulness of products with high content of 1 key nutrient, and to compare the traffic light system with warnings in terms of the perception of healthfulness. DESIGN: Images of front-of-pack (FOP) nutrition labels (the traffic light labeling system with different numbers of nutrients with low content, and warnings) were evaluated in study 1, whereas product labels featuring the different FOP nutrition labels were evaluated in study 2. SETTING: Online studies conducted in Montevideo, Uruguay. PARTICIPANTS: A total of 1,228 Uruguayan Facebook users. MAIN OUTCOME MEASURES: Perception of healthfulness. ANALYSIS: The researchers used ANOVA to evaluate the influence of FOP nutrition labels on perceived healthfulness. RESULTS: The inclusion of information about low nutrient content in the traffic light system statistically significantly increased the perception of the healthfulness of products with high nutrient content. Nutritional warnings showed healthfulness ratings similar to those of the simplified version of the traffic light system. CONCLUSIONS AND IMPLICATIONS: Information about low nutrient content in the traffic light system might be used to infer health, and thus could raise the perception of healthfulness and decrease the traffic light system's efficacy in discouraging the consumption of unhealthful products. A simplified version of the traffic light highlighting only high-nutrient content or nutritional warnings seems to overcome this problem.

The reformulation of the food products available in the marketplace to improve their nutritional quality has been identified as one of the most cost-effective policies for controlling the global obesity pandemic. Front-of-pack (FOP) nutrition labelling is one of the strategies that has been suggested to encourage the food industry to reformulate their products. However, the extent to which certain FOP labels can encourage product reformulation is dependent on consumer reaction. The aim of the present work was to assess consumers' perception towards product reformulation in the context of the implementation of nutritional warnings, an interpretive FOP nutrition labelling scheme. Three product categories were selected as target products: bread, cream cheese and yogurt, each associated with high content of one target nutrient. For each category, six packages were designed using a 3â¯×â¯2 experimental design with the following variables: product version (regular, nutrient-reduced and nutrient-free) and brand (market leader and non-market leader). A total 306 Uruguayan participants completed a choice experiment with 18 choice sets. Reformulated products without nutritional warnings were preferred by participants compared to regular products with nutritional warnings. No apparent preference for products reformulated into nutrient-reduced or nutrient-free product versions was found, although differences depended on the product category and the specific reformulation strategy. Preference for reformulated products without nutritional warnings was more pronounced for non-market leaders. Results from the present work suggest that reformulation of foods in the context of the implementation of nutritional warnings holds potential to encourage consumers to make more healthful food choices and to cause a reduction of their intake of nutrients associated with non-communicable diseases.

OBJECTIVE: The current study aimed to assess Uruguayan consumers' accounts of their own need to change their dietary patterns, their intended changes and the barriers related to doing so, and to compare the intentions and barriers with the recommendations of the national dietary guidelines. DESIGN: An online survey with 2381 Uruguayan employed adults, aged between 18 and 65 years, 65 % females, was conducted. Participants had to answer two open-ended questions related to changes they could make in the foods they eat and/or the way in which they eat to improve the quality of their diet and the reasons why they had not implemented those changes yet. Content analysis using inductive coding by two researchers was used to analyse the responses. RESULTS: Consumers mainly intended to change consumption of types of foods, particularly eating more fruits, vegetables and legumes and consuming less flour, but also intended to alter their eating patterns. Lack of time and the fact that healthy foods are perceived as being more expensive than unhealthy foods were major barriers to behaviour change. Some of the recommendations of the dietary guidelines, particularly those related to enjoying cooking and meals and engaging in it as a social activity, were not represented in consumer accounts. CONCLUSIONS: Accompanying policies to the dietary guidelines need to underline the importance of changes in dietary patterns, including greater enjoyment and sharing food preparation and meals in the company with others, address misconceptions about flour, and provide concrete, consumer-derived recommendations on how to enact the guidelines.

OBJECTIVE: The aim of the present work was to evaluate the influence of two front-of-pack nutrition information schemes (traffic-light system and Chilean warning system) on consumer purchase of ultra-processed foods in a simulated online grocery store. DESIGN: Following a between-subjects design, participants completed a simulated weekly food purchase in an online grocery store under one of three experimental conditions: (i) a control condition with no nutrition information, (ii) a traffic-light system and (iii) the Chilean warning system. Information about energy (calories), sugar, saturated fats and salt content was included in the nutrition information schemes. SETTING: Participants were recruited from a consumer database and a Facebook advertisement. SUBJECTS: People from Montevideo (Uruguay), aged 18-77 years (n 437; 75 % female), participated in the study. All participants were in charge of food purchase in the household, at least occasionally. RESULTS: No significant differences between experimental conditions were found in the mean share of ultra-processed foods purchased by participants, both in terms of number of products and expenditure, or in the mean energy, sugar, saturated fat and salt content of the purchased items. However, the Chilean warning system decreased intended purchase of sweets and desserts. CONCLUSIONS: Results from this online simulation provided little evidence to suggest that the traffic-light system or the Chilean warning system in isolation could be effective in reducing purchase of ultra-processed foods or improving the nutritional composition of the purchased products.
