RESUMO

OBJECTIVE: To explore the specific type of messages people consider most appropriate for a mass communication campaign aimed to promote healthy eating in the context of the implementation of nutritional warnings. DESIGN: Online study including multiple-choice and open-ended questions. SETTING: Uruguay, 1 of the Latin American countries with the highest prevalence of overweight and obesity. PARTICIPANTS: A total of 859 participants were recruited using social media. They were diverse in terms of gender, age, educational level, socioeconomic status, and self-reported body mass index. PHENOMENON OF INTEREST: Participants were presented with 3 series of messages and were asked to select the 1 they perceived as the most appropriate and to provide a brief explanation for their selection. ANALYSIS: Descriptive statistics for the multiple-choice questions and inductive coding for the responses to the open-ended questions. RESULTS: Participants tended to prefer messages that conveyed a cue to action for achieving changes to their perceived ability to make healthful food choices. Although messages related to the promotion of informed food choices were the most frequently preferred, messages related to negative health consequences and health benefits were also selected repetitively. CONCLUSIONS AND IMPLICATIONS: Communication campaigns aimed at promoting healthy eating through the use of nutritional warnings could include different contents to target specific segments with different motivations.

RESUMO

Several studies have shown that the inclusion of front of pack nutritional warnings is a potentially effective strategy to encourage consumers to avoid products with high content of nutrients associated with non-communicable diseases. In this context, the present work aimed at exploring consumers' reaction towards sodium reduction in the context of the implementation of warnings in three scenarios: package evaluation, tasting and intention to re-purchase the product after tasting, using white bread as case study. A total of 171 consumers participated in the study that encompassed four parts. Firstly, consumers received two bread samples with different salt content (2.00% and 1.38% salt) under blind conditions and were asked to rate their overall liking and to indicate the one they preferred. Then, they were asked to look at four bread packages differing in graphic design and the presence of warnings. They had to rate their expected liking and to indicate the one they would purchase. Finally, consumers were asked to try the bread they had previously chosen, to assess their overall liking and to indicate their willingness to purchase it again. Salt content significantly affected consumer hedonic reaction towards the breads. Two consumer segments with different preference for the salt content in bread were identified: 58% of consumers preferred the bread with 2.00% salt while 42% preferred breads with 1.38% salt. However, when looking at the packages the majority of consumers in both groups selected bread packages that did not feature warnings. In addition, after having tried the bread, most consumers were willing to buy the bread they had previously chosen again, which is promising in terms of reaching sustainable changes towards lower salt levels. Results from the present work suggest that, in the case of bread, nutritional warnings have potential to shift consumers' preferences to lower sodium content, even after trying the products.

RESUMO

Although several efforts to promote breastfeeding have been implemented worldwide, the prevalence of exclusive breastfeeding in the first 6 months of life remains low. One of the factors responsible for this trend is the widespread sales and marketing of breast-milk substitutes. In this context, the present work aimed at exploring mothers and health professionals' social representations of breastfeeding and infant formula. The study was conducted in Montevideo (Uruguay), as part of the periodic assessment performed by the Uruguayan government to monitor the marketing of breast-milk substitutes according to the OMS/UNICEF NetCode toolkit. A total of 330 mothers of children under 24 months old and 154 health professionals were recruited at 33 health care facilities. Participants were asked to complete two word association tasks, one with breastfeeding and the other with infant formula. Inductive coding was used to classify the responses into categories and dimensions. The structure of the social representations was explored considering the frequency of mention and the average rank of appearance of the categories. Results showed that mothers' social representations mainly positioned breastfeeding as a feeding practice, whereas infant formulas were mainly perceived as a complement to breast-milk that provides support. In the case of health professionals, the social representations of breastfeeding and infant formulas were in line with scientific evidence and health recommendations. These results suggest that efforts to promote breastfeeding should focus on raising public awareness of the risks associated with breast-milk substitutes and on overcoming the systemic barriers to breastfeeding, particularly among working mothers.

RESUMO

Consumer studies conducted under central location test (CLT) conditions continue to be dominant in product research and context evocation have been suggested as an avenue to partly mitigate the lack of real consumption settings. In this research the influence of evoked context on product acceptability was investigated in eight diverse consumer studies (138-268 participants per study) through the use of between-subjects designs that allowed the comparison of hedonic scores obtained with and without evoked context. In a departure from previous research, consumers mentally evoked their typical consumption contexts for the focal product categories and content analysis of descriptions of these situations showed them to often be idiosyncratic. Results were partly product- and situation-specific, and in this regard replicated past research. The evoked context only significantly modified hedonic scores in two of the eight studies, whereas it increased sample discrimination in three studies. Thus, accumulating evidence now supports the conclusion that evoked context is less rather than more likely to impact hedonic responses. Nonetheless, a benefit of context evocation is to give products a more complete meaning, and this may motivate their continued use in CLT settings. For researchers who wish to continue their use, key considerations in implementation are discussed, including relevance in home-use testing (HUT). By asking consumers to describe a typical eating occasion for the tested products, useful understanding of product use and pairings is gained. Such data can be easily elicited from consumers and obtained independently of context evocation.

[ABSTRACT]. Objective. To identify the food industry’s arguments against front-of-package nutrition labels in Uruguay. Methods. Content analysis and inductive coding were applied to the comments made by the food industry during the public consultation on the draft decree regulating the inclusion of front-of-package nutrition labels (warnings) in Uruguay. Results. Most of the comments expressed concern about the high prevalence of obesity and noncommunicable diseases in the country and emphasized a commitment to implementing actions to help combat these health problems. However, 81% of the comments disagreed with the draft decree presented for public consultation; these included general criticisms of its validity. The content of the comments related to seven areas: lack of rationale for the measure; violation of international commitments; criticisms of the warning system; discrimination against industrialized packaged food; criticisms of the nutrient profile model; other criticisms of aspects specific to the draft decree; and adverse economic effects. For each area, there is discussion of the technical and normative relevance and consistency of the content presented by the industry representatives. Conclusions. Despite apparent agreement about the need to adopt measures, it is clear that the food industry is strongly opposed to the policy and, in particular, to the warning system. The results of this analysis may help to facilitate the process of implementing similar regulations in other countries.

RESUMO

The high availability of products with high sugar content, particularly among those targeted as children, has been identified as one of the factors that contribute to the childhood obesity epidemic. For this reason, product reformulation has been recommended as one of the strategies that can be implemented to achieve short-term reductions in children's sugar intake. In this context, the objective of this study was to evaluate the feasibility of using cross-modal (taste-odor-texture) interactions as a strategy for reducing the sugar content of products targeted at children, using milk desserts as case study. A series of 5 vanilla milk desserts were formulated: a control sample with 12% added sugar and 4 sugar-reduced samples (7% added sugar) prepared following a 2 × 2 experimental design by varying vanilla (0.4% and 0.6% w/w) and starch (4.3% and 4.7% w/w) concentrations. A total of 112 children (8-12 years old) tasted the desserts and performed a dynamic sensory characterization task using either temporal check-all-that-apply or temporal dominance of sensations. In addition, they assessed the overall liking of all samples. Results showed that sugar-reduced samples did not significantly differ from the control sample in terms of their average overall liking scores. However, individual differences in children's hedonic reaction were found; three clusters of children with distinctive liking patterns were identified. The increase in vanilla and starch concentration led to an increase in overall liking for over 80% of the children. Sensory dynamic profiles revealed significant but subtle differences among samples. Results from the present work suggest that cross-modal interactions could contribute to minimizing the sensory changes caused by sugar reduction, which could enable to achieve larger reductions if implemented in the context of gradual sugar reduction programs.

RESUMO

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.

RESUMO

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.

RESUMO

New processing technologies are gaining popularity worldwide due to several advantages related to food safety, shelf life extension, nutritional and sensory quality. However, consumers can be cautious of food products produced using these technologies. In this context, the objectives of the study were to explore consumers' spontaneous associations with fruit juices processed using different technologies, and to study the influence of food technology neophobia on those associations. A study with 423 Brazilian consumers was conducted to evaluate their perception of five types of juices (fresh juice, cold pressed juice, pasteurized juice, pressurized juice and non-pressurized juice) using word association. Participants also answered the Food Technology Neophobia Scale (FTNS) and a series of socio-demographic questions. Results showed that consumers' attitudes towards processing technologies were mainly defined by top-down processes. Fresh, cold pressed and non-pressurized juice were mainly associated with healthy and natural products, whereas concepts including references to processing technologies were associated with processed products and unhealthiness. Food technology neophobia moderated consumers' perceptions of juice processing technologies. Interestingly, consumers with high technology neophobia perceived juices processed by both conventional and innovative technologies more negatively than those with low or medium levels of neophobia.

RESUMO

Check-all-that-apply (CATA) questions have become one of the most popular methods for sensory characterisation with consumers. Temporal CATA (TCATA) is an extension of the former that takes into account the dynamic nature of sensory perception. The aim of the present work was to expand the methodological comparison of CATA and TCATA questions, considering the characterisation of solid products that undergo substantial oral processing when consumed. Five studies involving a total of 731 consumers were conducted with different product categories: dried apricots, peas, cheese, bread and milk chocolate. A between-subjects experimental design was used to compare the static and dynamic versions of CATA questions. For comparison purposes, TCATA data were analysed as CATA by collapsing the data into four fixed time intervals (quarters). The four quarters of TCATA were compared to results from CATA considering the frequency of use of the terms, sample discrimination, and product configurations. The temporal aspect of TCATA did not largely modify the average citation proportion of terms or the maximum citation proportion for individual terms. Significant differences among samples were established for most of the terms in both CATA and TCATA evaluations, albeit some subtle differences between the two methods were found. These differences were dependent on the product category and the specific sensory characteristics that were relevant for describing the focal samples. The largest differences were found for Study 5 (milk chocolate), for which TCATA identified a few additional insights on the evolution of similarities and differences among samples. However, in most cases general findings were virtually identical for both methodological approaches. In light of these results, the extra effort of using a dynamic sensory characterisation method compared to a static one, may, in many instances, not be warranted.

RESUMO

OBJECTIVE: To evaluate the impact of message framing on attitudes towards messages aimed at promoting the use of nutritional warnings, behavioural intention and actual behaviour, evaluated through visual attention to nutritional warnings and the choice of a snack product during a real choice task. DESIGN: Following a between-subjects design, participants were exposed to loss-framed nutrition messages, gain-framed nutrition messages or non-nutrition-related messages (control group). After evaluating the messages, participants were asked to select a snack product as a compensation for their participation. The experiment was conducted using an eye tracker. SETTING: Montevideo (Uruguay). PARTICIPANTS: Convenience sample of 201 people (18-51 years old, 58 % female). RESULTS: The average percentage of participants who fixated their gaze on the nutritional warnings during the choice task was slightly but significantly higher for participants who attended to nutrition messages (regardless of their framing) compared with the control group. Participants who attended to loss-framed messages fixated their gaze on the warnings for the longest period of time. In addition, the healthfulness of the snack choices was higher for participants exposed to nutrition-related messages compared with the control group. CONCLUSIONS: Results from the present work suggest that nutrition messages aimed at increasing awareness of nutritional warnings may increase consumers' visual attention and encourage more heathful choices. The framing of the messages only had a minor effect on their efficacy.

RESUMO

In the current context of increasing worldwide concern about the prevalence of health problems related to high sodium intake, reducing the sodium content of food products has been identified as a cost-effective strategy to improve public health. The present work was aimed to assess the effect of salt reduction on consumers' perception, using white rice as case study. Particular emphasis was put on exploring individual differences in consumers' reaction towards salt reduction. A preliminary study, using a trained panel, was conducted to determine the difference threshold for salt in rice. The consumer study involved 156 consumers and encompassed three parts. First, consumers were presented with a 150 g portion of cooked rice prepared without added salt and were asked to indicate how much salt they would add to it (without tasting). Then, they were presented with six white rice samples differing in their salt content and were asked to indicate their overall liking using a 9-point hedonic scale, to asses adequacy of saltiness intensity using a 5-point just-about-right scale, and to indicate whether they would add salt to the rice. Finally, consumers completed a short survey about their salt consumption habits, interest in health and socio-demographic profile. As expected, results revealed large heterogeneity in consumers' hedonic reaction towards salt reduction: two consumer segments with different hedonic reaction were identified. Both consumer segments also differed in their hedonic sensitivity and tolerance to salt reduction in rice. Significant differences between consumer segments were found in their salt consumption habits, in particular related to salt addition to food, and also in their interest in reducing salt intake. These results suggest that eating habits might play a major role in shaping our preferences, highlighting the potential of gradual salt reduction as a strategy for reducing sodium intake.

RESUMO

Food products targeted at children are usually marketed using persuasive elements aimed at creating positive hedonic and emotional associations. For this reason, changes in children's emotional associations with unhealthy food products can discourage their consumption. In this context, the aim of the present study was to compare children's emotional associations with food products featuring different front-of-pack (FOP) nutrition labelling schemes. A total of 492 children (6-12 years old) were randomly divided into three groups, each of which evaluated a series of packages featuring different FOP nutrition labelling schemes: guidelines daily amount (GDA), traffic light system (TLS) and nutritional warnings. For each of the six packages and three unpackaged products, children were asked to select all the emoji from a list that described how they would feel eating the product. Data were analyzed using generalized linear models. FOP nutrition labelling significantly influenced the frequency of use five of the 16 emoji. In general, children who evaluated packages with directive and semi-directive schemes used emoji associated with positive emotions less frequently than those who evaluated packages with the GDA system. The effect of FOP nutrition labelling scheme on emotional associations was moderated by age and type of school. The effect of directive and semi-directive FOP nutritional schemes, in special nutritional warnings, tended to be higher for younger children and children from public schools. These results suggest that FOP nutrition labelling may contribute to discouraging consumption of products with high content of nutrients associated with non-communicable diseases among children.

RESUMO

Nutritional warnings highlighting products with high content of nutrients associated with non-communicable diseases have emerged as a potentially efficient alternative to discourage consumption of unhealthful products. However, the relative influence of this front-of-pack nutrition information scheme compared to other label features is still under researched. In this context, the aim of the present work was to study the influence of nutritional warnings and other information commonly displayed on food labels to convey health associations on consumers' choice and visual attention. A choice-conjoint study using labels of cookies and crackers was implemented considering the following three variables: front-of-pack nutrition information (nutritional warnings vs. facts up front panel), nutrient claim (present vs. absent) and type of product (conveying health vs. hedonic associations). A total of 124 people completed the task using the monitor of an eye-tracker. Participants were asked to select the label they would prefer to buy if they were in a supermarket. Nutritional warnings were efficient in attracting consumers' attention and required less time and fewer fixations to process than the facts up front panel. In addition, their inclusion on the labels significantly discouraged consumers' choice of labels. However, type of product was the most important variable influencing the choice of both cookies and crackers. Results from the present work confirm the potential of nutritional warnings as directive front-of-pack nutrition labelling scheme and stress that they cannot be expected to cause radical changes in consumers' eating habits due to their competition with other product features. Instead, they are expected to encourage consumers to select the most healthful option within a product category.

RESUMO

Emoji are increasingly used for emotional expression in computer-mediated communications and represent a relevant source of information for consumer companies about consumer's food-related attitudes and behaviours. However, given that emoji convey a wide range of meanings an in-depth understanding of how consumers interpret them is necessary to enable their use in food-related consumer research. The purpose of this research was to explore consumers' interpretations of facial emoji. In an online survey with 1084 adults from the USA, an open-ended question was used to uncover meanings associated to 33 common facial emoji (in Apple platform rendition iOS 6.0). Participants also evaluated the emotional valence and arousal of the emoji using Self-Assessment Manikins (SAM). The latter confirmed that facial emoji can span broad ranges of emotional valence and arousal and convey a corresponding range of different emotions. Although emoji conveyed their unique and intended meaning, semantic meanings were multiple and bestowed by associations of varying strength depending on the specific emoji being considered. This emphasised that emoji interpretation and use can be flexible, as also seen in internet resources dedicated to emoji meaning. Implications for food-related consumer research are discussed.

RESUMO

OBJECTIVE: To investigate the relative influence of nutritional warnings and 2 marketing strategies commonly used in food labels, nutrient claims, and fruit images on consumers' healthfulness judgments. DESIGN: Labels of cereal bars were designed according to a full factorial design with 3 2-level variables: images of fruit (with vs without), nutrient claims about the fiber content (with vs without), and nutritional warnings about excessive content of sugar and saturated fat (with vs without). SETTING: Experiment conducted in Montevideo, Uruguay. PARTICIPANTS: One hundred Uruguayan people, 75% female, aged 18-56 years. MAIN OUTCOME MEASURES: Healthfulness perception and eye-tracking variables. ANALYSIS: The researchers used ANOVA to evaluate the influence of the experimental design's variables on perceived healthfulness and eye-tracking measures. RESULTS: Nutritional warnings caught participants' attention and reduced the amount of visual attention needed to evaluate healthfulness. Participants mainly relied on nutritional warnings to make healthfulness judgments. CONCLUSIONS AND IMPLICATIONS: Findings of the current work confirm the potential of nutritional warnings to influence consumers' healthfulness perception, overriding the effect of other label cues used by the food industry to convey the concept of healthfulness.

RESUMO

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.

RESUMO

Contextual and individual variables have been shown to play a key role in shifting consumers' emotional reaction to food products. Socio-economic status (SES) influences consumer past and present experiences with food products, as well as the social and personal meanings attached to foods, which can strongly affect their emotional associations. In this context, the aim of the present work was to explore differences in food-related emotional associations with foods of Brazilian consumers from low and middle/high SES. A total of 300 Brazilian participants of different SES were asked to complete four free-listing tasks related to the emotions they associated with the foods they liked the most/least and the foods they associated with positive/negative emotions. Participants elicited a wide range of associations, most of which were related to moods and emotions. The identified moods and emotions have been included in word-based emotion questionnaires. Although similar terms were elicited by both SES groups, differences in their frequency of mention were found. In addition, SES groups also differed in the foods they associated with positive and negative emotions, which could be explained by differences in their eating patterns. Results stress the need to further study the influence of SES on food-related emotional associations.
