Assessing research needs for informing pet food industry decisions

Abstract The global pet food industry continues to grow being fueled by increased pet ownership, higher disposable income of pet owners, and a growing demand for premium products. While this growth has attracted increased interest of researchers in animal nutrition and product formulation, the overall body of management and economic literature to guide product innovation and marketing strategies in the pet food industry is still limited. This study aims to identify and highlight the most important, relevant, and current research needs for informing product and marketing decisions in pet food. The methods include a quantitative analysis of primary data from a survey of 76 pet food decision makers involved in the procurement of raw material, production, and marketing. The findings suggest the need for extensive research in various areas pertaining to the quality and availability of raw materials, processing methods, and forecasting consumer preferences. The findings also emphasize high value research areas such as identifying alternative protein sources, enhancing nutrient retention during the extrusion process, identifying opportunities for product innovation that align with customer preferences, and accurately predicting consumer demand.

Positive serial dependence in ratings of food images for appeal and calories

Food is fundamental to survival, and our brains are highly attuned to rapidly process food stimuli. Neural signals show that foods can be discriminated as edible or inedible as early as 85ms after stimulus onset,1 distinguished as processed or unprocessed beginning at 130ms,2 and as high or low density from 165ms.3 Recent evidence revealed specialized processing of food stimuli in the ventral visual pathway,4,5,6 an area that underlies perception of faces and other important objects. For many visual objects, perception can be biased toward recent perceptual history (known as serial dependence7,8). We examined serial dependence for food in two large samples (n>300) who rated sequences of food images for either "appeal" or "calories." Ratings for calories were highly correlated between participants and were similar for males and females. Appeal ratings varied considerably between participants, consistent with the idiosyncratic nature of food preferences, and tended to be higher for males than females. High-calorie ratings were associated with high appeal, especially in males. Importantly, response biases showed clear positive serial dependences: higher stimulus values in the previous trials led to positive biases, and vice versa. The effects were similar for males and females and for calories and appeal ratings and were remarkably consistent across participants. These findings square with recently found food selectively in the visual temporal cortex, reveal a new mechanism influencing food decision-making, and suggest a new sensory-level component that could complement cognitive strategies in diet intervention.

Impact of olfactory priming on mental representations of food concepts and subsequent food choice

Previous research suggests that food odors act as a prime and influence food choice outside of awareness. Little is known about how odors prime (healthy) food choices. We hypothesized that odors could activate mental representations of food concepts, interacting with cognitive processes underlying food decision-making. We tested this by examining which concepts (healthy, sensory, or product-specific) are activated by odors and how this impacts subsequent food choices. In a between-subjects design, 112 participants were divided into three conditions: healthy odor (apple or banana), unhealthy odor (chocolate or caramel), and non-odor (control). Participants were exposed to one condition for 5 min and then completed a lexical decision task and a screen-based food choice task. The lexical decision task included four word categories: healthy-related, sensory-related, neutral words, and non-words. Reaction times were recorded and computed for each category. Participants were asked to choose one food they wanted to eat from four (in-)congruent food word options and repeated it four times (one for each odor). Results showed participants responded slower to non-words than other words, and slower to healthy and sensory words than neutral words. However, odor exposure did not influence reaction times, nor did the interaction between odor condition and word category affect reaction times. Participants were more likely to choose unhealthy foods regardless of odor exposure. Thus, ambient sweet odors did not prime food-related information or choice. We recommend additional testing using a broader range of odors and word categories to fully validate the association of an odor with a concept.

Nutrition Education for Adolescents: Building Healthy Eating Habits at Growing Age

This study explores the effectiveness of nutrition education in building healthy eating habits among adolescents, which is a crucial age for growth and development. Although adolescents have basic knowledge about the importance of nutrition, such as the benefits of vitamins and minerals, the information they receive is often not in-depth or practical enough to be applied in daily habits. This study identifies that current nutrition education programs are often less interactive and not always relevant to the context of adolescent life. Through qualitative methods, this study reveals the challenges faced by adolescents in implementing healthy eating habits, such as peer influence and limited access to healthy food. The findings suggest that a more holistic approach is needed to address these barriers. Strategies that involve more practical and participatory educational methods, as well as support from families and communities, have proven effective in increasing understanding and application of nutrition principles. The results of the study explain that educational programs involving practical activities, educational games, and family and community participation can help adolescents make healthy food decisions and support their growth and overall health.

Intersecting perspectives: Advocating for sustainable family meals across generations

Adolescents in Germany eat fewer animal products than their parents, often for sustainability reasons. We investigated how adolescents differ from their parents' generation in sustainability food-choice motives, consumption of animal products, and corresponding behaviors such as advocating for and influencing decisions towards more sustainable family meals. In an online questionnaire, an educationally diverse sample of 500 adolescents (M = 17.9 years, range = 15–20) and 500 adults of their parents' generation (M = 52.2 years, range = 45–60) reported food-choice motives, their own and their family's diet style, how they advocate for sustainable food decisions at family meals (e.g., less meat), and how they influence different steps in family meal planning (e.g., grocery shopping). The two generations did not differ in sustainable food motives and mean consumption frequency of meat and animal products, but adolescents reported three times more often than their parents' generation to never eat meat. At shared family meals they advocated for eating plant-based substitutes (d = 0.27, p < 0.001) and other animal products (β = −0.15, p = 0.02) more often than their parents' generation, but not for eating less meat. Adolescents advocated more frequently for sustainable food decisions at shared meals the more important sustainability motives were to them (β = 0.53, p < 0.001), and the less meat (β = −0.35, p < 0.001) and fewer other animal products (β = −0.11, p = 0.015) they consumed. Adolescents motivated towards sustainability have the potential to impact the family's dietary choices through reverse socialization processes. These findings challenge current theories that suggest only parents influence their children, neglecting the role of adolescents as potential agents of change for improved family and planetary health.

Intuitive eating in the COVID-19 era: a study with university students in Brazil

BackgroundThe recurrence of weight gain is attributed to the homeostatic regulation of hunger and satiety signals, influenced by metabolic state, nutrient availability, and non-homeostatic mechanisms shaped by reinforced consequences from experiences. In response, Evelyn Tribole and Elyse Resch proposed Intuitive Eating (IE) in 1980, countering restrictive diets. IE, inversely correlated with Body Mass Index (BMI), binge eating, and anxiety/depression symptoms, fosters mind–body-food harmony by recognizing hunger and satiety cues. IE encourages meeting physiological, not emotional, needs, permitting unconditional eating, and relying on internal signals for food decisions. Amidst university students’ stress, exacerbated during the COVID-19 pandemic, understanding their eating behavior, particularly intuitive eating levels, becomes crucial.ObjectiveThis study aimed to assess the IE level of Brazilian students during the COVID-19 pandemic.MethodsThis cross-sectional study, the first to analyze the Intuitive Eating of students in Brazil during the pandemic, was conducted using an online questionnaire.ResultsThe sample comprised 1335 students, most of whom were women (82.17%), with a mean age of 26.12 ± 7.9 years, and a healthy nutritional status (57.58%). The mean IE score was 3.2 ± 0.6. A significant association was found between the confinement situation, the type of housing unit, and the IE subscale-Unconditional Permission to Eat (p = 0.043). However, there was no association between the other subscales and the total IE scale. Regarding self-reported mental and eating disorders, the most frequent were anxiety (21.2%), depression (6.5%), and binge eating disorder (BED) (4.7%). IE was negatively associated with BED (B = − 0.66; p < .001), bulimia nervosa (B = − 0.58; p < .001), body mass index (BMI) (p < .001) and self-reported anxiety (B = − .102; p = 0.16). The male sex showed a higher IE score compared with the female sex (p < .001).ConclusionWhile no significant association was found between IE and the confinement situation, a significant association was found between housing type and the Unconditional Permission to Eat subscale.

Traffic light nutrition labelling policy: A path to promoting healthier eating habits in Pakistan.

Dear Editor, While the global burden of diet-related diseases continues to escalate1, it is disheartening to see that Pakistan, like many other Lower-Middle Income Countries (LMICs)2, has not yet ultimately adopted the system that can significantly assist consumers in making healthier food decisions. In Pakistan, the prevalence of obesity, diabetes, and other non-communicable disease conditions is on the rise, posing a substantial economic and health burden on individuals and the healthcare system2. Many countries like the United States, Australia, and the United Kingdom use the traffic light nutrition labeling system, which is a valuable tool for empowering consumers to make informed food choices quickly 3. It provides a simple way for people to quickly assess the nutritional value of a product using a color-coding system3. Green labels indicate healthier options, amber labels suggest moderate consumption and red labels highlight food that should be consumed sparingly4. The simple color-coding system empowers consumers to make healthier decisions and can contribute to a reduction in diet-related diseases4. The traffic light system works particularly well in settings with high illiteracy rates, as is prevalent in Pakistan since it relies on simple color coding rather than textual information5. As consumers, we lack a clear and uniform method for evaluating the nutritional components of the food we buy. This deficiency not only obstructs the capacity to make healthy food choices but also sustains the prevalence of diet-related issues. Color-coded labeling would help people with low literacy levels to understand the nutrition information available on food products easily. However, Traffic Light nutrition labelling has not been adopted in Pakistan. To confront this challenge, policymakers, health organizations, and government authorities should take swift and decisive action. The government must take the lead in implementing clear regulations that mandate the use of traffic light nutrition labels on packaged food items. These regulations should accompany strict enforcement measures. Launching public awareness campaigns about the benefits of the traffic light system can help familiarize consumers with this approach and generate demand for healthier food products. Collaboration and engagement with food manufacturers and retailers to ensure a smooth transition to the traffic light system is imperative to encourage the production of healthier food consumption. Implement a system of periodic reviews and updates of the labeling system to ensure its collective effectiveness and relevance to the evolving nutritional landscape. ---Continue

How a food scanner app influences healthy food choice

The use of mobile applications to assist with food decision making has increased significantly. Although food scanner applications provide nutritional information to consumers in the marketplace, little is known about their effects on users’ intentions and behavior. This research investigates whether a mobile food scanner app can influence consumers toward healthier food choices. Four studies tested whether information displayed through a food scanner app (as opposed to no information or front-of-packaging label information) influenced purchase intentions for food products (Studies 1–3) or led consumers to make healthier food choices (Study 4). Application-provided information enhanced hypothetical choice and purchase intentions of healthy products in comparison no information, but it did not influence real behavior when participants made choices in an experimental supermarket. Information provided through a food scanner app was systematically outperformed by front-of-packaging label information.

Are Dutch adults equally susceptible to nudging and pricing strategies? Secondary analyses of the Supreme Nudge parallel cluster-randomised controlled supermarket trial

BackgroundSupermarket interventions are promising to promote healthier dietary patterns, but not all individuals may be equally susceptible. We explored whether the effectiveness of nudging and pricing strategies on diet quality differs by psychological and grocery shopping characteristics.MethodsWe used data of the 12-month Supreme Nudge parallel cluster-randomised controlled supermarket trial, testing nudging and pricing strategies to promote healthier diets. Participants were Dutch speaking adults aged 30–80 years and regular shoppers of participating supermarkets (n = 12) in socially disadvantaged neighbourhoods. Data on psychological characteristics (food-related behaviours; price sensitivity; food decision styles; social cognitive factors; self-control) and grocery shopping characteristics (time spent in the supermarket; moment of the day; average supermarket visits; shopping at other retailers; supermarket proximity) were self-reported at baseline. These characteristics were tested for their moderating effects of the intervention on diet quality (scored 0–150) in linear mixed models.ResultsWe included 162 participants from intervention supermarkets and 199 from control supermarkets (73% female, 58 (± 10.8) years old, 42% highly educated). The interventions had no overall effect on diet quality. Only five out of 23 potential moderators were statistically significant. Yet, stratified analyses of these significant moderators showed no significant effects on diet quality for one of the subgroups and statistically non-significant negative effects for the other. Negative effects were suggested for individuals with lower baseline levels of meal planning (β − 2.6, 95% CI − 5.9; 0.8), healthy shopping convenience (β − 3.0, 95% CI − 7.2; 1.3), and healthy food attractiveness (β − 3.5, 95% CI − 8.3; 1.3), and with higher levels of price consciousness (β − 2.6, 95% CI − 6.2; 1.0) and weekly supermarket visits (β − 2.4, 95% CI − 6.8; 1.9).ConclusionsAdults with varying psychological and grocery shopping characteristics largely seem equally (un)susceptible to nudging and pricing strategies. It might be that certain characteristics lead to adverse effects, but this is not plausible, and the observed negative effects were small and statistically non-significant and may be explained by chance findings. Verification of these findings is needed in real-world trials based on larger sample sizes and with the use of more comprehensive interventions.Trial registrationDutch Trial Register ID NL7064, 30th of May, 2018, https://onderzoekmetmensen.nl/en/trial/20990

Understanding Poor Food Decisions with Jack A. Bobo

Understanding Poor Food Decisions with Jack A. Bobo

Thinking of food: The mental representation of healthy foods as unprepared

We find that people implicitly and explicitly represent healthy foods they categorize as healthy in their purest, least prepared forms but represent foods they categorize as unhealthy in their most prepared forms (e.g., a veggie patty is represented as frozen while a beef burger is represented in a bun with melted cheese and ready to eat). We find this effect across several studies using both image and word sorting measures in explicit tasks and implicit association tasks. The effect results from the perception of health and taste as two conflicting goals. Preparation (e.g., cooking, adding toppings) makes food more delicious, which creates categorization ambiguity. Hence, healthy food is thought of as unprepared. Indeed, individual differences in perceived health-taste goal conflict moderate the effect. Critically, the representation of healthy foods matters for food decisions. In an experiment that manipulated the descriptive language on a restaurant menu, emphasizing the preparation of foods increased participants’ preference for healthy foods (with no improvement for unhealthy foods).

The Time-Course of Food Representation in the Human Brain.

Humans make decisions about food every day. The visual system provides important information that forms a basis for these food decisions. Although previous research has focused on visual object and category representations in the brain, it is still unclear how visually presented food is encoded by the brain. Here, we investigate the time-course of food representations in the brain. We used time-resolved multivariate analyses of electroencephalography (EEG) data, obtained from human participants (both sexes), to determine which food features are represented in the brain and whether focused attention is needed for this. We recorded EEG while participants engaged in two different tasks. In one task, the stimuli were task relevant, whereas in the other task, the stimuli were not task relevant. Our findings indicate that the brain can differentiate between food and nonfood items from ∼112 ms after the stimulus onset. The neural signal at later latencies contained information about food naturalness, how much the food was transformed, as well as the perceived caloric content. This information was present regardless of the task. Information about whether food is immediately ready to eat, however, was only present when the food was task relevant and presented at a slow presentation rate. Furthermore, the recorded brain activity correlated with the behavioral responses in an odd-item-out task. The fast representation of these food features, along with the finding that this information is used to guide food categorization decision-making, suggests that these features are important dimensions along which the representation of foods is organized.

Food Choice as an Ethical Practice: Top-Down and Bottom-Up Approaches to a Possible Synthesis

Food, reflecting individual and collective ethical choices, is the focus of this essay, which explores the profound interrelationship between food practices and the moral principles that govern them. Beginning with Feuerbach’s maxim ‘Man is what he eats,’ the essay explores the complex relationship between diet, ethics, and philosophy, showing how every food decision is inextricably linked to ethical, social, and environmental considerations. It explores the transformation of the concept of ‘food’ from a mere dietary choice to an expression of a conscious lifestyle. It shows how everyone’s food choices reflect and influence our interaction with the world. Through historical and contemporary analysis, the multiple dimensions of diet are explored: from responsibility towards undernourished people to environmental sustainability, from the debate on omnivorism to the promotion of ethical diets such as vegetarianism and veganism. The exposition is then articulated through two dominant ethical currents: the top-down approach, based on universal principles, and the bottom-up approach, which emphasizes the importance of virtues and values in the specific context of food. The essay not only brings these perspectives into dialoguebut also invites critical reflection on the role of food in defining human identity and morality, underlining the urgency of a global ethical commitment that reconciles personal needs with collective and environmental ones.

Exploring the perception of small and medium food enterprises in Lincolnshire, UK on the use of front‐of‐pack nutrition labels by consumers

SummaryThe food and drink industry is the UK's largest manufacturing sector, and small to medium‐sized enterprises (SMEs) play a key role in the UK's food system. This study investigates food‐providing SMEs' knowledge of nutrition labels and perceptions of the use of front‐of‐pack nutrition labels in making informed and healthy food choices by consumers. The SMEs were based in Lincolnshire, UK, and comprised food manufacturers (75%), food retailers (14%) and food service providers (11%) (n = 35). A 25‐item questionnaire was developed and validated to collect responses. The questionnaire link was disseminated by email and completed online. Comparisons were made between competing answers using Cochran's Q tests, each with post‐hoc pairwise McNemar test comparisons. Confidence intervals were computed using ordinal regressions. More than half of the SMEs' products (58%) had UK traffic light (TL) colour‐coded schemes and % Guideline Daily Amounts (GDAs). The SMEs stated that the TL label was the best format that provided ‘at‐a‐glance’ information, and this was significantly higher than %GDA and interpretative text (Ps &lt; 0.003). Nearly 49% of the SMEs were unaware of the front‐of‐pack labels being not mandatory in the United Kingdom. Many (86%) acknowledged that the nutrition information on food products was helpful or very helpful for consumers in making purchasing decisions. The SMEs seemed to place the costs of implementing FOP labels on food products above their helpfulness in making healthier food decisions by consumers. This research is one of the first to investigate the perceptions of SMEs on how consumers utilise nutrition labels when making healthier food choices in the United Kingdom. Government subsidies on the costs incurred by incorporating TL labelling on the products are necessary in order to have front of pack (FOP) labels mandatory in the United Kingdom. Greater food industry involvement in academic and policy‐related research is essential to creating a healthier and more sustainable food environment.

Impact of land restitution benefits on Water, Energy and Food (WEF) misgovernance and social injustice

Land restitution has been used to achieve redistributive justice. However, such social justice has been compromised by the misgovernance of water, energy, and food (WEF) which has resulted in distributive injustices and compromised welfare outcomes. The objective of the study was to ascertain the land restitution benefactor impacts on WEF misgovernance in lieu of offsetting social injustice. The study was carried out in Matatiele, Magareng and Greater Taung Local Municipalities in South Africa. A purposively selected sample of 1184 households was obtained through a cross-sectional survey using a semi-structured questionnaire. Vulnerability indices, independent sample t-tests and Propensity Score Matching were used to analyze the data. The results showed that land restitution beneficiaries were vulnerable to WEF misgovernance relative to social injustice. In addition, becoming a land restitution benefactor had a significant impact and increased the level of vulnerability to WEF misgovernance. This was mainly through increased exposure and sensitivity to WEF misgovernance. Benefiting from land restitution did not have an impact on vulnerability to WEF social injustice, even though exposure and adaptive capacity to social injustice were increased. The study concludes that benefiting from land restitution increased vulnerability to WEF misgovernance while having no impact on social injustice. The study recommends improving access and fixing dilapidated WEF infrastructure in land-restituted areas. Furthermore, there is a need to implement livelihood-improving programs in addition to social protection support to enhance access to WEF resources. Water, energy, and food (WEF) decision-making should be decentralized to improve participation, governance, and procedural justice.

Differences in Discounting Behavior and Brain Responses for Food and Money Reward.

Most neuroeconomic research seeks to understand how value influences decision-making. The influence of reward type is less well understood. We used functional magnetic resonance imaging (fMRI) to investigate delay discounting of primary (i.e., food) and secondary rewards (i.e., money) in 28 healthy, normal-weighted participants (mean age = 26.77; 18 females). To decipher differences in discounting behavior between reward types, we compared how well-different option-based statistical models (exponential, hyperbolic discounting) and attribute-wise heuristic choice models (intertemporal choice heuristic, dual reasoning and implicit framework theory, trade-off model) captured the reward-specific discounting behavior. Contrary to our hypothesis of different strategies for different rewards, we observed comparable discounting behavior for money and food (i.e., exponential discounting). Higher k values for food discounting suggest that individuals decide more impulsive if confronted with food. The fMRI revealed that money discounting was associated with enhanced activity in the right dorsolateral prefrontal cortex, involved in executive control; the right dorsal striatum, associated with reward processing; and the left hippocampus, involved in memory encoding/retrieval. Food discounting, instead, was associated with higher activity in the left temporoparietal junction suggesting social reinforcement of food decisions. Although our findings do not confirm our hypothesis of different discounting strategies for different reward types, they are in line with the notion that reward types have a significant influence on impulsivity with primary rewards leading to more impulsive choices.

Abstract P483: Food Purchase Priorities and Healthy Food Purchase Supports and Barriers for U.S. General and Low-Income Consumers: A Quantitative Survey

Introduction: Identifying priorities and attributes that influence food purchase decisions will inform interventions and strategies to promote healthy eating. Aim: This study aimed to identify food purchase priorities and healthy food purchase supports and barriers for the general population and those with limited household income. Methods: Participants were recruited by a market research company in May 2023 and were required to be ≥ 18 years old, not work in healthcare/medical/nutrition or advertising/public relations/marketing/market research and be the primary/shared food decision maker for the household. Recruitment quotas ensured age, income, gender and geographic region approximated 2022 US census data (n=1,182) (Census-representative group, CRG). A sample with limited income and participation in federal food or healthcare programs (low-income group, LIG) was also recruited (n=506). The survey was administered online in May and June 2023. Differences between LIG and CRG were assessed using z-tests (p &lt; 0.05). Results: Taste was most commonly rated by CRG as very or extremely important in household food purchasing (87%). Availability, price, ingredients and nutritional value were also important to at least two-thirds of CRG. Taste was similarly important to LIG (85%), but they were more likely to rate price and less likely to rate availability, nutritional value and ingredients as important. When prompted to choose the most important factor, price and taste were the most common responses, chosen by similar proportions of CRG, while price was the most important factor for LIG, followed by taste. CRG versus LIG were more likely to prioritize personal taste over cost, health and nutrition information on labels, buying local and selecting according to nutrition, brand and origin/sourcing information. CRG were less likely than LIG to prefer a lower cost and usually select according to price. LIG were more likely than CRG to state that nothing supports them in selecting healthier foods and less likely to have found support from good-tasting recipes, advance meal or grocery list preparation, cooking equipment access, following influencers, recommendations from organizations or consulting a dietitian/nutritionist. Conversely, LIG were more likely to identify price and availability as barriers to selecting healthier foods, and less likely to see long preparation time, small servings sizes or nothing as barriers. Conclusions: Cost is a strong barrier to healthy eating, especially with limited income, along with taste, while nutrition is not a leading influence on food choice. Strategies to enable healthy eating among low-income households must prioritize taste and cost.

Taste, sustainability, and nutrition: Consumers' attitude toward innovations in aquaculture products

Marine aquaculture is one of the solutions to provide sustainable nutritious food. While technological and product development in the marine aquaculture industry is challenging, the industry is also facing consumer skepticism. Therefore, it is crucial to understand consumers' food decisions to deliver the benefits of marine aquaculture on environmental sustainability and human nutrition. This study aims to test how a sheer cognition of innovative or traditional production methods influences the USA consumers' acceptance of marine aquaculture products.In an online experimental study, 186 consumers from the USA evaluated their perceptions of a series of marine aquaculture products that vary in processing levels. Participants were randomly assigned to one of the three conditions: Tradition, Technology, and Control condition. In the Tradition condition, participants were told the products are produced in a traditional way. In contrast, a high-tech production system is emphasized in the Technology condition. In the Control condition, the producer uses a conventional method to farm seafood. The results of a set of general linear models for repeated measures reveal that emphasizing traditional production methods is associated with better perceptions of tastefulness, healthiness, and sustainability. Further analysis of a structural equation model found that the difference between the Tradition versus Technology brand image mainly lies in the perceived sincerity of the producer. The image of a traditional producer contributes to better consumer trust, and it further leads to a higher perceived value of healthiness and sustainability.The results of the study shed light on the strategies to accelerate technological advances and the social acceptance of innovative nutritious food. The research is one of the early attempts in the aquaculture industry to collect consumer feedback on tech/product development. The process can support future tech/product research projects by enhancing the societal embeddedness of marine aquaculture innovation.

Cool or hot: How dietary restraint produces both positive and negative eating behaviors

Restrained eating is the tendency to restrict food intake to control weight. Restrained eaters’ behavior is thought to be under cognitive control. The dual process model classifies human cognition into two systems: 1) the reflective system, which is slow, deliberative, and conscious (i.e., the “cool system”), and 2) the automatic system, which is fast and unconscious (i.e., the “hot system”). Previous research has argued food items are more likely to be emotionally arousing for restrained eaters, which triggers the hot system. We hypothesize that restrained eaters make less caloric food decisions when their cool system is engaged. An undergraduate sample of 241 students reported their level of restraint, mindful eating, and food cravings. The hot system path is represented by a food decision that must be made quickly and offers an immediate reward, since exerting time pressure induces hot system processing. The cool system path is represented by a computerized menu selection task, in which the individual has unlimited time to consider the food decision. Results show restrained eating reduces caloric intake intentions via the process of mindful eating through the cool system. However, restrained eating increases caloric snack selection via the process of food cravings through the hot system. Restrained eaters should limit their exposure to food decision-making situations in which their hot system may be triggered. Our findings suggest nudging may be useful for restrained eaters, in that it encourages cool system processing.

Visual communication design: a neglected factor in nutrition promotion via packaged food labels.

Packaging design is a communication device and a critical component in branding strategy, and has relevance for food policy. Presently, packaging-related nutrition policy initiatives focus on the role of regulated claims, nutrition information panels and front-of-pack nutrition labels to help guide consumer food choices and address high prevalences of discretionary and ultra-processed food consumption in many countries. However, these nutrition labelling systems are not optimized as public health policy tools as many consumers do not use them to inform their food choices. Visual communication design theory posits that a designer orders the elements and principles of design into hierarchies that prioritize certain elements over others, and that some of these elements are more dominant and given more emphasis than others. The overall design of the package thereby directs consumer attention to some aspects of pack design (e.g., characters, contents of the package) and away from others (e.g., nutrition details). Dual processing frameworks propose that food decisions are made with the interplay between automatic and rational thinking processes. Packaging designs affect whether consumers rely predominantly on automatic or rational thinking to select a food. This narrative review outlines the role of food packaging design and how it impacts the clear communication of nutrition aspects of food products and how the use of nutrition information by consumers to make decisions may depend upon design structures in packaging. This article attests that nutrition scientists and policy makers should incorporate visual communication design into research on the food packaging as a public health promotion tool. A stronger focus on the communication of regulated front-of-pack nutrition information can be made with a re-evaluation of the hierarchy of elements in the front-of-pack design enabling consumers to make healthier decisions.
