The high prevalence of food insecurity in the United Kingdom has been exacerbated by the cost-of-living crisis. In high-income countries, those experiencing food insecurity struggle to buy and consume foods that meet Government healthy eating recommendations, and are at increased risk of obesity, linked to poor diet quality. Individuals in high-income countries purchase most of their food to consume at home from supermarkets, making this an important context within which healthier and environmentally sustainable food purchasing should be supported. However, the lived experience of supermarket food purchasing in people living with obesity and food insecurity has not been explored in depth. Adults, living in England and Scotland, who self-identified as living with obesity and food insecurity and looking to reduce their weight, were recruited to take part in semi-structured interviews (n = 25) or focus groups (n = 8) to explore their experience of shopping for food in the supermarket. Using thematic analysis, four main themes were generated: 1) the Restricted Consumer ; restrictions around the type of food purchased, where food can be purchased and the resulting emotional toll, 2) the Conscious Consumer ; decision making and effortful practices both in preparation of and during the shopping trip, 3) Mitigating the Rising Cost of Food ; agency and actions taken to mitigate high food prices, 4) Stigma ; instances of perceived and/or experienced weight and poverty-related stigma and the physical actions and cognitive social comparisons used to minimise stigma. Findings provide insights for evidence-based policy on the need for upstream changes within the wider food system to address the social determinants of health and support people living with obesity and food insecurity to eat healthier and more sustainable diets.

Different front-of-package labelling (FOPL) schemes have been developed worldwide to encourage informed and healthier food purchase decisions. However, few studies have formally compared different schemes, particularly in the Latin American context. This study aimed to assess the effects of four different FOPL schemes on the objective understanding of the nutritional content and intention to purchase products. This single-blinded multi-arm randomised controlled trial was conducted using a face-to-face survey with adult shoppers, recruited at supermarkets in Costa Rica (n = 1350). Participants randomly assigned to intervention groups saw 12 mock-up products presented at random and balanced orders featuring one FOPL scheme or none: black octagonal warning labels (OWL), Nutri-Score (NUS), traffic-light labelling (TFL), guideline daily amounts (GDA), or no FOPL scheme (control group). Similar number of participants were analysed in each group: OWL (n = 264), NUS (n = 279), TFL (n = 263), GDA (n = 273), and control (n = 271). Compared to the control group, the odds for correctly identifying the least harmful option more often were three times higher in the OWL group (OR 3.08; 95% CI, 2.26-4.20), and 89%, 57% and 19% higher in the TFL (1.89; 95% CI, 1.40-2.56), the GDA (1.57; 95% CI, 1.16-2.21) and the NUS (1.19; 95% CI 0.89-1.60), respectively. OWL also was more efficacious in helping participants to correctly identify a product with excessive amounts of sugars, sodium, and/or saturated fats, as well as in encouraging the intention to purchase the least harmful or the intention to choose none of the options in the choice task. OWL performed best in helping shoppers to correctly identify when a product contained excessive amounts of nutrients to limit, to correctly identify the least harmful option, and to intend to purchase the least harmful option, more often., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Sugar sweetened-beverage (SSB) consumption contributes to poor diet quality and diet-related chronic diseases. One effective public health strategy to reduce SSB consumption is to tax SSB. Laboratory approaches can complement existing methods to improve understanding of how taxes on SSB influence purchasing. In this study we sought to develop and validate an experimental marketplace that presents participants with beverages typically available at grocery stores. Participants who drink SSB (n = 73) hypothetically shopped for beverages for their household with a 40% SSB tax and with no tax (order counterbalanced). Relative to the no tax condition, SSB purchasing was lower in the tax condition. We also found that self-reported beverage expenditures were correlated with experimental marketplace beverage expenditures. Most participants noticed the tax and agreed that the experimental marketplace was easy to use. Using an experimental marketplace is a promising way to explore SSB tax design to improve public policy. We present ideas for future studies that can include real and hypothetical outcomes., Competing Interests: Declaration of competing interest None., (Copyright © 2025 Elsevier Ltd.

Food decision-making among urban consumers of low income is comprised of a complex interplay of strategies, influenced by sociodemographic and environmental factors. This study was conducted in the Bronx, New York City, a borough marked by disparities and limited healthy food access. The study aimed to co-develop with urban consumers of low income a conceptual framework representing food procurement decision-making, with special attention paid to the multifaceted dynamics of food acquisition in the context of food insecurity. In-depth interviews and focus group discussions were conducted with bodega customers and food pantry clients to inform a food procurement decision tree. The framework illustrated the hierarchical order of food sources and coping strategies influenced by factors like household income, food assistance program participation, perceived access to food sources, living conditions, and immigration status. While grocery stores and supermarkets were the primary food sources, secondary sources like bodegas and food pantries were relied upon when physical or financial access was constrained, and superstores when resources were available. Farmers' markets and online grocery shopping were tertiary sources and oftentimes unrealistic options for participants. This study highlights the challenges faced by consumers of low income in accessing healthy food and underscores the need for food pantries to meet nutritional and cultural food needs. The findings emphasize the importance of considering contextual factors in interventions and policies to address food insecurity and their implications on community health., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Food purchasing behaviours are shaped by the choices available to shoppers and the way they are offered for sale. This study tested whether prominent positioning of more sustainable food items online and increasing their relative availability might reduce the environmental impact of foods selected in a 2x2 (availability x position) factorial randomised controlled trial. Participants (n = 1179) selected items in a shopping task in an experimental online supermarket. The availability intervention added lower-impact products to the regular range. The positioning intervention biased product order to give prominence to lower-impact products. The primary outcome was the environmental impact score (ranging from 1 "least impact" to 5 "most impact", of each item in shopping baskets) analysed using Welch's ANOVA. Secondary outcomes included interactions (analysed via linear regression) by gender, age group, education, income and meat consumption and we assessed intervention acceptability (using different frames) in a post-experiment questionnaire. Compared to control (mean = 21.6), mean eco quintile score was significantly reduced when availability & order was altered (−2.30; 95%CI: 3.04; −1.56) and when order only was changed (−1.67; 95%CI: 2.42; −0.92). No significant difference between availability only (−0.02; 95%CI: 0.73; 0.69) and control was found. There were no significant interactions between interventions or by demographic characteristics. Both interventions were acceptable under certain frames (positioning emphasising lower-impact products: 70.3% support; increasing lower-impact items: 74.3% support). Prominent positioning of more sustainable products may be an effective strategy to encourage more sustainable food purchasing. Increasing availability of more sustainable products alone did not significantly alter the environment impact of products selected. [ABSTRACT FROM AUTHOR]

Unhealthy food and non-alcoholic beverage marketing (UFM) adversely impacts children's selection and intake of foods and beverages, undermining parents' efforts to promote healthy eating. Parents' support for restrictions on children's exposure to food marketing can catalyse government action, yet research describing parent concerns is limited for media other than television. We examined parents' perceptions of UFM and their views on potential policies to address UFM in supermarkets and on digital devices – two settings where children are highly exposed to UFM and where little recent research exists. We conducted in-depth interviews with sixteen parents of children aged 7-12 from Victoria, Australia, analysing the data thematically. Parents perceived UFM as ubiquitous and viewed exposure as having an immediate but temporary impact on children's food desires and pestering behaviours. Parents were concerned about UFM in supermarkets as they viewed it as leading their children to pester them to buy marketed products, undermining their efforts to instil healthy eating behaviours. Parents generally accepted UFM as an aspect of contemporary parenting. Concern for digital UFM was lower compared to supermarkets as it was not directly linked to pestering and parents had limited awareness of what their children saw online. Nevertheless, parents felt strongly that companies should not be allowed to target their children with UFM online and supported government intervention to protect their children. While parents supported government policy actions for healthier supermarket environments, their views towards restricting UFM in supermarkets varied as some parents felt it was their responsibility to mitigate supermarket marketing. These findings could be used to advocate for policy action in this area. [Display omitted] [ABSTRACT FROM AUTHOR]

Regular consumption of ultra-processed foods (UPF) is a risk factor for morbidity and mortality. UPF are widely available in supermarkets. Nudging and pricing strategies are promising strategies to promote healthier supermarket purchases and may reduce UPF purchases. We investigated whether supermarket nudging and pricing strategies targeting healthy foods, but not specifically discouraging UPF, would change UPF availability, price, promotion and placement (UPF-APPP) in supermarkets and customer UPF purchases. We used data from the Supreme Nudge parallel cluster-randomized controlled trial, testing the effect of a combined nudging and pricing intervention promoting healthy products. The Dutch Consumer Food Environment Score (D-CFES) was used to audit 12 participating supermarkets in terms of UPF-APPP. We used customer loyalty card data of the first twelve intervention weeks from 321 participants to calculate the proportion of UPF purchases. Descriptive statistics were used to assess differences in D-CFES between supermarkets. Mixed model analyses were used to assess the association between the D-CFES and UPF purchases and the effect of the intervention on UPF purchases. No difference in the D-CFES between intervention and control supermarkets were found. No statistically significant association between the D-CFES and UPF purchases (β = -0.00, 95%CI: -0.02, 0.01) and no significant effect of the intervention on UPF purchases (β = 0.02, 95%CI: -0.07, 0.12) was observed. Given the significant proportion of unhealthy and UPF products in Dutch supermarkets, nudging and pricing strategies aimed at promoting healthy food purchases are not sufficient for reducing UPF-APPP nor purchases, and nationwide regulation may be needed.Trial registration number: Dutch Trial Register ID NL7064, May 30, 2018, https://trialsearch.who.int/Trial2.aspx?TrialID=NTR7302., Competing Interests: Declaration of competing Interest None declared., (Copyright © 2024 The Authors.

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., Competing Interests: Declaration of competing interest The authors declare that there is no conflict of interest.

Animal welfare (AW) is a growing concern for consumers in Germany; however, not all consumers regularly purchase products that have been produced according to high AW standards. The goal of the present study is to test the effect of a multilayered nudge to increase the availability and improve the visibility of AW products in a 3D online virtual supermarket (VS). The nudge included a shelf with AW products (referred to as AW shelf) which was made visible through banners and footsteps on the floor of the VS. The sample of this pre-registered experiment consisted of n = 374 German consumers who regularly purchase meat, milk, and eggs. The results demonstrated that the multilayered nudge was highly effective: the percentage of AW products purchased in the nudging condition was almost twice as high as in the control group. Furthermore, we investigated variables that mediate (ease of finding AW products in the VS) and moderate (price sensitivity) the effectiveness of the multilayered nudge, but no evidence for an effect was obtained. We conclude that multilayered nudges may be a promising tool to increase consumers' AW product purchases. More research is needed to replicate this finding with a field study in a real supermarket.

One novel strategy to shift food choices in digital shopping environments is to automatically recommend healthier alternatives when an unhealthy choice is made. However, this raises the question which alternative products to recommend. This study assesses 1) whether healthier food swap recommendations are effective, even though the unhealthy choice was made in the presence of visible FOP nutrition labels, and 2) how the similarity of the alternatives influences the acceptance of food swap recommendations. Based on a pre-test, similarity of the recommendation was operationalized in terms of animal-based versus plant-based options. A randomized controlled trial (healthy food swap recommendation conditions: none, similar animal-based, dissimilar plant-based, or mixed animal- and plant-based) with 428 Dutch participants was conducted in a simulated online supermarket. Additional healthier food swap recommendations improved the nutritional quality of the final basket compared to only providing Nutri-Score nutrition labels (−1.7 mean FSA score, p <.001, medium Cohen's d = −0.48). Compared to the dissimilar condition, acceptance of an alternative was more likely in the mixed (odds-ratio = 2.78, p =.015) and in the similar condition (odds-ratio = 2.24, p =.048), but the nutritional quality of the final basket did not differ between treatment conditions. Individuals in treatment conditions who did not receive any recommendation (i.e. only made healthy choices) had higher Nutri-Score familiarity and general health interest than individuals who received recommendations. This suggests that for individuals with higher knowledge and motivation FOP nutrition labels were sufficient, whereas for individuals with lower knowledge and motivation additional food swap recommendations can improve dietary choices. Food swap recommendations may act as meaningful reminders by disrupting the automatic choice process and triggering individuals to rethink their (unhealthy) choice. [ABSTRACT FROM AUTHOR]

A shift from predominantly animal-based to plant-based consumption can benefit both planetary and public health. Nudging may help to promote such a shift. This study investigated nudge effects on plant-based alternatives to meat and dairy in an online supermarket. We conducted a two-arm, parallel-group, randomized controlled real-life online supermarket trial. Each customer transaction was randomized to a control arm (regular online supermarket) or an intervention arm (addition of placement, hedonic property and dynamic social norm nudges promoting meat and dairy alternatives). Outcomes were the aggregate of meat and dairy alternative purchases (primary outcome), the number of meat purchases, dairy purchases, meat alternative purchases, and dairy alternative purchases (secondary), and retailer revenue (tertiary). Generalized linear mixed models with a Conway-Maxwell Poisson distribution were used to estimate incidence rate ratios (IRRs). Analyzed data included 8488 transactions by participants (n = 4,266 control arm, n = 4,222 intervention arm), out of which 2,411 (66%) were aged above 45 years, 5,660 (67%) were females, and 1,970 (23%) lived in socially disadvantaged neighborhoods. Intervention arm participants purchased 10% (IRR 1.10 (95% CI 0.99-1.23)) more meat and dairy alternatives and 16% (1.16 (0.99-1.36)) more meat alternatives than control arm participants, although these findings are not statistically significant. There was no difference in dairy alternative purchases (1.00 (0.90-1.10)). Intervention arm participants purchased 3% less meats (0.97 (0.93-1.02)) and 2% less dairy products (0.98 (0.95-1.02)) than control participants. Retailer revenue was not affected (0.98 (0.95-1.01)). Online nudging strategies alone did not lead to a statistically significant higher amount of plant-based purchases, but replication of this work is needed with increased study power. Future studies should also consider nudging strategies as part of a broader set of policies to promote plant-based purchases. TRIAL REGISTRATION: Prospectively registered on 14 th of May 2022.

A transition towards sustainable diets ensuring food security while preserving ecosystems is necessary, but remains challenging. Low-income consumers, particularly those experiencing food insecurity, require specific consideration since they face financial constraints when making food choices, leading to poorer diets. However, little is known about the place given to sustainability in their choices. This study thus aims to identify the role played by sustainability in the food values of food-insecure consumers in France. Twenty-nine semi-structured interviews with users of a social grocery store were conducted to investigate food values and actual behaviours, with a focus on the four dimensions of sustainable diets - health, economic, sociocultural and environmental. Verbatims were analysed through thematic analysis. Five core values were identified, namely health and nutrition, naturalness, trust and control, solidarity and frugality, and preferences. Participants valued all dimensions of food sustainability but notably valued less the environmental dimension. Despite various strategies, participants felt unable to adhere to their values in practice, mainly because of their socioeconomic vulnerability. They insisted on their lack of control over their food behaviour. These findings provide insights into the disempowerment experienced by consumers with low financial resources regarding more sustainable food choices. Our study calls for interventions addressing affordability issues and considering consumers' food values, while providing opportunities to make consumers feel involved in the transition of the food system., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: The authors declare having no conflict of interest.

Objective: One method of influencing an individual's food consumption involves placing unhealthy snacks further away from individuals, known as the "proximity effect". However, only one laboratory study has explored the effect while both an unhealthy and a healthy option are presented simultaneously. Further, little is known about the potential underpinning mechanisms of the effect. The current study aims to replicate the proximity effect in a competitive environment, and to explore the role of visual salience and effort in the proximity effect.Method: Fifty-six participants were asked to complete a two-part questionnaire under the cover story of a relaxation study. Two bowls were presented to participants, each containing either 250 g chocolate M&M's or 250 g mixed fruit pieces. Each bowl was positioned either 20 cm or 70 cm from the participant, creating four proximity conditions. Consumption of each snack was compared between proximity conditions.Results: No main effects were found. A significant interaction between snack type and chocolate position was found (p = .010, ȵ2 = 0.159), with fruit consumption being significantly higher when chocolate was at located at 20 cm compared to 70 cm (53.35 g vs 22.35 g, p = .042). Higher visual salience of each snack type correlated to more of the snack being consumed, ps < .017. Results were similar when calories consumed were analysed.Conclusions: We found an unconventional proximity effect where the consumption of a snack did not depend on its position, but rather the relative position of another snack. Implications of the study could inform café and supermarket layouts to exploit the interaction between moving healthy items closer in addition to moving unhealthy items further away, in order to maximise choice of healthy items.

Restructuring food environments, such as online grocery stores, has the potential to improve consumer health by encouraging healthier food choices. The aim of this study was to investigate whether repositioning foods within an experimental online grocery store can be used to nudge healthier choices. Specifically, we investigated whether repositioning product categories displayed on the website main page, and repositioning individual products within those categories, will influence selection. Adults residing in Australia (n = 175) were randomised to either intervention (high-fibre foods on top) or comparator condition (high-fibre foods on the bottom). Participants completed a shopping task using the experimental online grocery store, with a budget of up to AU$100 to for one person's weekly groceries. The results of this study show that the total fibre content per 100 kcal per cart (p < .001) and total fibre content per cart (p = .036) was higher in the intervention compared to comparator condition. Moreover, no statistical difference between conditions was found for the total number of fibre-source foods (p = .67), the total energy per cart (p = .17), and the total grocery price per cart (p = .70) indicating no evidence of implications for affordability. Approximately half of the participants (48%) reported that they would like to have the option to sort foods based on a specific nutrient criterion when shopping online. This study specifically showed that presenting higher-fibre products and product categories higher up on the online grocery store can increase the fibre content of customers' purchases. These findings have important implications for consumers, digital platform operators, researchers in health and food domains, and for policy makers., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

A transition to a more sustainable diet likely requires substituting proteins of animal origin with alternatives like plant-based foods. Yet consumers are not regularly consuming alternative protein products, and one potential explanation is that the dominant food retail infrastructure is not oriented in favour of these foods. This study provides an in-depth exploration of the role of supermarkets in plant-based protein consumption in a Canadian food retail setting. A mixed-methods approach involving seven supermarket audits, 24 consumer interviews, and five key informant interviews was used to explore the in-store context for plant-based protein purchasing as well as the forms of "fits" and "misfits" between the supermarket's strategies for retailing plant-based protein and consumer strategies when shopping for these products. Our findings suggest that supermarkets are simultaneously enabling and limiting consumers when it comes to alternative protein consumption by increasing the availability of plant-based options, but assuming basic strategies when it comes to marketing these products in-store. We propose several tactics that could facilitate greater uptake of these products, including placing plant-based meat and dairy substitutes on the same shelves as other meat and dairy products and the devotion of more resources to product promotions and the innovation of new varieties. In concluding, we contend that efforts to increase society's consumption of alternative protein products would greatly benefit from better understanding the supermarket's role in mediating this transition.

Many scholars have found evidence that low-income neighborhoods contain fewer supermarkets, but there is a lack of consensus regarding whether and how this matters to residents. A few qualitative studies have asked food desert residents about their experiences of their food environments, while a small number of other studies have utilized spatial analyses to examine actual shopping behaviors. To better understand barriers to food access, this study combines the two in a geo-ethnographic analysis. This study draws on data from a USDA-funded project about families and food to combine quantitative geographic data with qualitative interview data of 100 rural and urban low-income mothers of young children. For each participant, the nearest supermarket, as well most-frequented supermarket, was mapped, and distances to stores were calculated. On average, participants traveled more than twice as far as their nearest supermarket to reach a preferred store. Interviews with participants were conducted to assess the motivations and strategies of shoppers, in particular why they chose to bypass their nearest supermarkets. They shared a variety of reasons for doing so; foremost to find lower prices of food in order to stretch income and SNAP benefits. Access to transportation also played a major role in determining where people shopped for food. This research challenges scholars, policymakers, and health practitioners to look beyond proximate food environments to consider the lived experiences of food desert residents. Efforts to address poor food access should aim to increase household income, in addition to providing targeted food and nutrition assistance. [ABSTRACT FROM AUTHOR]

In visual marketing, the truism that "unseen is unsold" means that products that are not noticed will not be sold. This truism rests on the idea that the consumer choice process is heavily influenced by visual search. However, given that the majority of available products are not seen by consumers, this article examines the role of peripheral vision in guiding attention during the consumer choice process. In two eye-tracking studies, one conducted in a lab facility and the other conducted in a supermarket, the authors investigate the role and limitations of peripheral vision. The results show that peripheral vision is used to direct visual attention when discriminating between target and non-target objects in an eye-tracking laboratory. Target and non-target similarity, as well as visual saliency of non-targets, constitute the boundary conditions for this effect, which generalizes from instruction-based laboratory tasks to preference-based choice tasks in a real supermarket setting. Thus, peripheral vision helps customers to devote a larger share of attention to relevant products during the consumer choice process. Taken together, the results show how the creation of consideration set (sets of possible choice options) relies on both goal-directed attention and peripheral vision. These results could explain how visually similar packaging positively influences market leaders, while making novel brands almost invisible on supermarket shelves. The findings show that even though unsold products might be unseen, in the sense that they have not been directly observed, they might still have been evaluated and excluded by means of peripheral vision. This article is based on controlled lab experiments as well as a field study conducted in a complex retail environment. Thus, the findings are valid both under controlled and ecologically valid conditions. [ABSTRACT FROM AUTHOR]

There is a battle in the supermarket isle, a battle between what the consumer wants and what the retailer and others want her to see, and subsequently to buy. Product packages and displays contain a number of features and attributes tailored to catch consumers' attention. These are what we call external factors comprising the visual saliency, the number of facings, and the placement of each product. But a consumer also brings with her a number of goals and interests related to the products and their attributes. These are important internal factors, including brand preferences, price sensitivity, and dietary inclinations. We fit mobile eye trackers to consumers visiting real-life supermarkets in order to investigate to what extent external and internal factors affect consumers' visual attention and purchases. Both external and internal factors influenced what products consumers looked at, with a strong positive interaction between visual saliency and consumer preferences. Consumers appear to take advantage of visual saliency in their decision making, using their knowledge about products' appearance to guide their visual attention towards those that fit their preferences. When it comes to actual purchases, however, visual attention was by far the most important predictor, even after controlling for all other internal and external factors. In other words, the very act of looking longer or repeatedly at a package, for any reason, makes it more likely that this product will be bought. Visual attention is thus crucial for understanding consumer behaviour, even in the cluttered supermarket environment, but it cannot be captured by measurements of visual saliency alone.

Objective: To evaluate the influence of convenience and price of ultra-processed foods and beverages on purchases at supermarkets.Methods: The study used data on food and beverage acquisition for household consumption from the Brazilian Household Budget Survey, performed in a random sample of 55,970 households between 2008 and 2009. Foods and beverages were categorized into four groups, according to characteristics of food processing. Retail stores were grouped into supermarkets and other food stores. Proportion of calories from foods and beverages purchased at supermarkets and other food stores, and respective mean prices (R$/1000 kcal), were calculated according to households' geographical and socioeconomic characteristics. Effect of convenience in household purchases at retail stores was expressed by the acquisition of several food items at the same store. The influence of convenience and prices of ultra-processed products on purchases at supermarkets was analyzed using log-log regression model with estimation of elasticity coefficients.Results: The mean prices of foods and beverages purchased at supermarkets were 37% lower in comparison to other food stores. The share of ultra-processed foods and beverages in purchases made at supermarkets was 25% higher than at other food stores. An increase of 1% in prices of ultra-processed food items led to a 0.59% reduction in calorie acquisition at supermarkets (R2 = 0.75; p < 0.001). On the other hand, an increase of 1% in the number of food items purchased at supermarkets resulted in 1.83% increase in calorie acquisition of ultra-processed foods and beverages (p < 0.001).Conclusion: Convenience and lower relative prices of food items purchased at supermarkets, in comparison to other food stores, are relevant to explain higher share of purchases of ultra-processed foods and beverages at supermarkets.

To combat food waste, supermarkets offer food items at a reduced price in-store when they are close to the expiration date or perceived as suboptimal. It is yet unknown, however, which considerations consumers engage in when deciding about the offer, and whether focusing particularly on the price during food purchase might be related to greater food waste at home. Knowledge about both the consumers' food purchase process for these price-reduced foods and the potential wastage of price-focused consumers can contribute to the assessment of whether or not offering suboptimal food at reduced prices in-store actually reduces food waste across the supply chain. We explore these questions in a mixed-method study including 16 qualitative accompanied shopping interviews and a quantitative online experimental survey with 848 consumers in Denmark. The interviews reveal that the consumers interviewed assess their ability to consume the price-reduced suboptimal food at home already while in the store. Consumers consider the relation between product-related factors of package unit, expiration date, and product quality, in interaction with household-related factors of freezing/storing, household size/demand, and possible meal/cooking. The survey shows that consumers who are more price-focused report lower food waste levels and lower tendency to choose the optimal food item first at home, than those who are not emphasizing the price-quality relation or do not search for price offers to the same extent. Higher age and high education also played a role, and the price-focus is lower in high-income groups and among single households. The findings allow deriving recommendations for retailers and policy makers to support both the marketability and the subsequent actual consumption of price-reduced suboptimal food, but they also raise questions for further research of this underexplored area.

The supermarket is a promising location for stimulating healthier food choices by nudging interventions. However, nudging healthy food choices in the supermarket has shown weak effects to date. The present research introduces a new nudge based on the concept of affordances – i.e., an animated character – that invites interaction with healthy food products and examines its effectiveness and appreciation in a supermarket context. We present findings of a series of three studies. In Study 1, evaluations of the new nudge were collected, revealing that the nudge was appreciated. In Studies 2 and 3, field experiments were conducted to test the nudge's effect on vegetable purchases in a real-life supermarket. Study 3 demonstrated that vegetable purchases increased significantly (up to 17%) when the affordance nudge was placed on the vegetable shelves. Furthermore, customers appreciated the nudge and its potential for implementation. Taken together, this set of studies presents compelling findings illustrating the potential of the affordance nudge for increasing healthy choices in the supermarket. [ABSTRACT FROM AUTHOR]

Overconsumption of foods high in fat, sugars, and salt (HFSS) poses a significant risk to health. The government in England has passed legislation that would limit some price promotions of HFSS foods within supermarkets, but evidence regarding likely impacts of these policies, especially in online settings, is limited. This study aimed to determine whether there were any differences in the energy and nutrient content of shopping baskets after removing promotions on HFSS foods in an online experimental supermarket. UK adults (n = 511) were asked to select food from four categories with a £10 budget in an online experimental supermarket: confectionery; biscuits and crackers; crisps, nuts and snacking fruit; cakes and tarts. They were randomly allocated to one of two trial arms: (1) promotions present (matched to promotion frequency seen in a major UK retailer) (n = 257), or (2) all promotions removed from all products within the target food categories (n = 254). The primary outcome analysis used linear regression to compare total energy (kcal) of items placed in shopping baskets when promotions were present vs. absent, while secondary analyses investigated differences in nutrients and energy purchased from individual food categories. Mean energy in food selected without promotions was 5156 kcal per basket (SD 1620), compared to 5536 kcal (SD 1819) with promotions, a difference of -552kcal (95%CIs: -866, -238), equivalent to 10%. There were no significant differences in energy purchased for any individual category between groups. No evidence was found of other changes in nutritional composition of baskets or of significant interactions between the impact of promotions and participant characteristics (gender, age, ethnicity) on energy purchased. Removing promotions on HFSS foods resulted in significantly less total energy selected in an online experimental supermarket study., (Copyright © 2023 The Authors. Published by Elsevier Ltd..

Immersive virtual reality techniques present new opportunities for research into consumer behavior. The current study examines whether the increased realism of a virtual store compared to pictorial (2D) stimuli elicits consumer behavior that is more in line with behavior in a physical store. We examine the number, variety, and type of products selected, amount of money spent, and responses to price promotions and shelf display, in three product categories (fruit & vegetables, milk, and biscuits). We find that virtual reality elicits behavior that is more similar to behavior in the physical store compared to the picture condition for the number of products selected (Milk: Mstore = 1.19, Mvirtual = 1.53, Mpictures = 2.58) and amount of money spent (Milk: Mstore = 1.27, Mvirtual = 1.53, Mpictures = 2.60 Euro), and for the selection of products from different areas of the shelf, both vertically (purchases from top shelves, milk and biscuits: Pstore = 21.6%, Pvirtual = 33.4%, Ppictures = 50.0%) and horizontally (purchase from left shelf, biscuits: Pstore = 35.5%, Pvirtual = 53.3%, Ppictures = 66.7%). This indicates that virtual reality can improve realism in responses to shelf allocation. Virtual reality was not able to diminish other differences between lab and physical store: participants bought more products and spent more money (for biscuits and fruit & vegetables), bought more national brands, and responded more strongly to price promotions in both virtual reality and pictorial representations than in the physical store. Implications for the use of virtual reality in studies of consumer food choice behavior as well as for future improvement of virtual reality techniques are discussed. [ABSTRACT FROM AUTHOR]

Nutrition labels and ecolabels can support consumers to make healthier and more sustainable choices, and the former is now widespread. But there is no information on the impact of ecolabels in the presence of nutrition labels. The aims of this study were primarily to examine whether (1) ecolabels are effective at promoting sustainable purchasing behaviour if presented alongside nutrition labels; (2) and secondarily, whether nutrition labels are effective at promoting healthier purchasing if presented alongside ecolabels. Participants (N = 2730) visited an experimental online supermarket platform, and were randomised to see products with (1) environmental impact labels only; (2) nutrition (NutriScore) labels only; (3) both environmental and nutrition labels; (4) no labels. Linear regressions compared the mean environmental impact scores (EIS; primary outcome) and health scores of products in participants' shopping baskets across each condition. Compared to control (no labels) there were significant reductions in the EIS when environmental impact labels were presented: Alone (-1.3, 95%CI: -2.3 to -0.4) or With nutrition labels (-2.0, 95%CI: -2.9 to -1.0), with no evidence of differences in effectiveness between these two conditions. There was no evidence of an impact of nutrition labels on either the EIS or the healthiness of purchases, both when nutrition labels were shown alone and when ecolabels were also present. Environmental impact labels may be effective at encouraging more sustainable purchases alone or when used alongside nutrition labels. This adds to the evidence base on the feasibility and effectiveness of environmental impact labelling as an important measure to change dietary behaviour to improve planetary health.

Taxes and subsidies are a public health approach to improving nutrient quality of food purchases. While taxes or subsidies influence purchasing, it is unclear whether they influence total energy or overall diet quality of foods purchased. Using a within subjects design, selected low nutrient dense foods (e.g. sweetened beverages, candy, salty snacks) were taxed, and fruits and vegetables and bottled water were subsidized by 12.5% or 25% in comparison to a usual price condition for 199 female shoppers in an experimental store. Results showed taxes reduced calories purchased of taxed foods (coefficient = -6.61, CI = -11.94 to -1.28) and subsidies increased calories purchased of subsidized foods (coefficient = 13.74, CI = 8.51 to 18.97). However, no overall effect was observed on total calories purchased. Both taxes and subsidies were associated with a reduction in calories purchased for grains (taxes: coefficient = -6.58, CI = -11.91 to -1.24, subsidies: coefficient = -12.86, CI = -18.08 to -7.63) and subsidies were associated with a reduction in calories purchased for miscellaneous foods (coefficient = -7.40, CI = -12.62 to -2.17) (mostly fats, oils and sugars). Subsidies improved the nutrient quality of foods purchased (coefficient = 0.14, CI = 0.07 to 0.21). These results suggest that taxes and subsidies can influence energy purchased for products taxed or subsidized, but not total energy purchased. However, the improvement in nutrient quality with subsidies indicates that pricing can shift nutritional quality of foods purchased. Research is needed to evaluate if differential pricing strategies based on nutrient quality are associated with reduction in calories and improvement in nutrient quality of foods purchased.

Background: Over-reliance on convenience foods, including ready-meals, has been suggested as one contributor to obesity. Little research has systematically explored the nutritional content of supermarket ready-meals. We described the nutritional content and cost of UK supermarket ready-meals. Methods: We conducted a survey of supermarket own-brand chilled and frozen ready-meals available in branches of ten national supermarket chains in one city in northern England. Data on price, weight and nutritional content of meals in four ranges (‘healthier’, luxury, economy and standard) and of six types (macaroni cheese, meat lasagne, cottage pie, chicken tikka masala, fish pie, and sweet and sour chicken) were collected. Nutritional content was compared to ranges used to identify low, medium and high fat, saturated fat, sugar and salt in nationally recommended front-of-pack labelling. Results: 166 ready-meals were included from 41 stores. Overall, ready-meals were high in saturated fat and salt, and low in sugar. One-fifth of meals were low in fat, saturated fat, salt and sugar, including two-thirds of ‘healthier’ meals. Meals that were low for three out of the four front-of-pack nutrients were the cheapest. Conclusions: Supermarket ready-meals do not have a healthful nutritional profile overall. However, a number of healthier meals were available – particularly amongst meals specifically marked as ‘healthier’. There was little evidence that healthier meals necessarily cost more. Further effort is required to encourage producers to improve the nutritional profile of the full range of ready-meals, and not just those specifically labelled as ‘healthier’. [ABSTRACT FROM AUTHOR]

Previous research investigating what information shoppers seek when purchasing groceries has used either lab-experiments or observed shoppers in supermarkets. The present research investigates this question in a relatively naturalistic online-grocery environment. Forty participants completed their weekly shopping online while their eye-movements were recorded. Ten of the participants were subsequently interviewed to gain insight into their information seeking behaviour. We found that, when looking for products, 95% of participants navigated through the ‘virtual departments’, 80% used the ‘search’ facility, and 68% browsed the special offer pages. Once on the product pages, participants tended to look at the pictures of products, rather than examine detailed product information. To explain these findings, we suggest that online grocery sites simulate familiar supermarket environments, which may explain why consumers prefer to browse categories of products rather than use search terms. We also suggest that additional strategies are needed if consumers are to be encouraged to view detailed product information. [ABSTRACT FROM AUTHOR]

Food products have significant impacts on the environment over their life cycle. We investigated whether displaying products in ascending order of carbon footprint in an online supermarket environment can shift consumer choices towards more sustainable options. We examined whether the effect of the ordering intervention differs when the ordering is overt (information about the ordering is explicit), compared to when it is covert (participants not told about the ordering). We conducted a three-arm parallel-group randomised trial using 1842 online participants from England, Wales, and Northern Ireland. Participants shopped for a meal, choosing one product from each of six product categories in a simulated online supermarket. Six products were listed vertically on each product-category page. Products were randomly ordered for the control arm but ordered by carbon footprint in the covert and overt ordering arms. In the overt ordering arm, a statement was displayed at the top of each product page about the ordering of products. The primary outcome was whether one of the three most sustainable products was chosen in each product category. There was no effect of the covert ordering on the probability of choosing more sustainable products compared with the control arm (OR = 0.97, 95% CI 0.88-1.07, p = 0.533). Furthermore, we did not find evidence that the effects of the covert ordering and overt ordering differed (p = 0.594). Within the control condition, products in different positions were chosen with similar frequencies, suggesting that product positioning does not have an impact on choices. This may explain why re-ordering products had no effect. In the overt condition, only 19.5% of people correctly answered that the products were ordered according to sustainability in a follow-up question, suggesting that they didn't notice the statement. Results suggest that choices for grocery products might be too ingrained to be changed by subtle rearrangements of choice architecture like the ordering interventions, and highlight the difficulty of conveying information effectively to consumers in the online grocery shopping environment., Competing Interests: Declaration of competing interest None., (Crown Copyright © 2022.

Shoppers make many food choices while buying groceries. Children frequently accompany caregivers, giving them the potential to influence these choices. We aimed to understand low-income shoppers' perceptions of how children influence caregivers' purchasing decisions and how the supermarket environment could be manipulated to allow children to serve as change agents for healthy food purchasing in a primarily African-American community. We conducted thirty in-depth interviews, five follow-up interviews, one supermarket walk-through interview, and four focus groups with adult supermarket shoppers who were regular caregivers for children under age 16. We conducted one focus group with supermarket employees and one in-depth interview with a supermarket manager. Qualitative data were analyzed using iterative thematic coding and memo writing. Caregivers approached grocery shopping with efforts to save money, prevent waste and purchase healthy food for their families, but described children as promoting unplanned, unhealthy food purchases. This influence was exacerbated by the supermarket environment, which participants found to promote unhealthy options and provide limited opportunities for children to interact with healthier foods. Caregivers' suggestions for promoting healthy purchasing for shoppers with children included manipulating the placement of healthy and unhealthy foods and offering opportunities for children to taste and interact with healthy options.

Highlights: [•] Food marketing on public television in Honduras was rare. [•] Food marketing on public television consisted of advertisements for supermarkets. [•] Advertising of unhealthy foods was common on cable stations. [•] Nearly all food advertisements targeting children were marketing unhealthy foods. [Copyright &y& Elsevier]

Highlights: [•] Variations occur in energy content reductions of food products by consumers. [•] Nutrition knowledge is not utilized consistently when selecting products. [•] Ability to assess products’ energy contents is dependent on the familiarity with it. [•] The more familiar a product is, the more accurately its energy content is assessed. [•] Familiarity, price and taste are important food selection factors in supermarkets. [Copyright &y& Elsevier]

Abstract: This study compared the types of foods advertised in supermarket newspaper circulars across geographic region (US Census regions: northeast [n =9], midwest [n =15], south [n =14], and west [n =13]), obesity-rate region (i.e., states with CDC adult obesity rates of <25% [n =14], 25 to <30% [n =24], and ⩾30% [n =13]), and with MyPlate recommendations. All food advertisements on the first page of each circular were measured (±0.12-in.) to determine the proportion of space occupied and categorized according to food group. Overall, ⩾50% of the front page of supermarket sales circulars was devoted to protein foods and grains; fruits, vegetables, and dairy, combined, were allocated only about 25% of the front page. The southern geographic region and the highest obesity-rate region both devoted significantly more advertising space to sweets, particularly sugar-sweetened beverages. The lowest obesity-rate region and western geographic region allocated the most space to fruits. Vegetables were allocated the least space in the western geographic region. Grains were the only food group represented in ads in proportions approximately equal to amounts depicted in the MyPlate icon. Protein foods exceeded and fruits, dairy, and vegetables fell below comparable MyPlate proportional areas. Findings suggest supermarket ads do not consistently emphasize foods that support healthy weight and MyPlate recommendations. More research is needed to determine how supermarket newspaper circulars can be used to promote healthy dietary patterns. [Copyright &y& Elsevier]

Abstract: The nutritional quality of Australian breakfast cereals is not systematically monitored despite the importance of breakfast for general health. We examined whether the nutritional quality of Australian breakfast cereals has improved between 2004 and 2010, and whether any change could be detected after the introduction of Daily Intake Guide (DIG) front-of-pack labelling. Supermarket surveys were conducted in 2004 and 2010 using the same methodology to collect information from the nutrition information panels of Australian breakfast cereals and the nutrient content of cereals was compared by year. Breakfast cereals with and without DIG labelling in 2010 were also compared. Nutritional quality was assessed using UK Traffic Light criteria. No significant difference was detected in nutritional composition of breakfast cereals between 2004 and 2010. There was no notable improvement in nutritional composition of breakfast cereals marketed as the same product in both years. Overall there has been little improvement in the nutritional quality of Australian breakfast cereals in the 6year period. A large proportion of Australian breakfast cereals were considered high sugar. In conclusion, the introduction of DIG labelling does not appear to have promoted product reformulation, and breakfast cereals carrying DIG labels were not consistently healthier.

Abstract: The present study investigated the effect of taxing high-energy dense products and subsidizing low-energy dense products on changes in calorie consumption. More specifically, we hypothesized that ‘more impulsive’ individuals were less influenced by such pricing strategies compared to ‘less impulsive’ individuals. Contrary to our hypothesis, results showed that ‘more impulsive’ individuals adjusted their calorie consumption with regard to price changes whereas ‘less impulsive’ participants were less influenced by price changes. Furthermore, taxing high-energy dense products was more successful in reducing calorie consumption than subsidizing low-energy dense products. [Copyright &y& Elsevier]

Abstract: Ample experimental research has demonstrated the impact of peer influence on food intake in adolescents and adults. However, none of these studies focused social modeling effects on food purchases in supermarkets. This study investigated whether the food purchase behavior of a confederate peer would be adopted by the participant. Teenage girls (N =89) were asked to perform a shopping task in a local supermarket. They had to shop with a same-sex confederate peer who had been instructed earlier to purchase either five low-kilocaloric food products, five average-kilocaloric or five high-kilocaloric food products. Significant main effects for the experimental purchase condition and hunger were found on the amount of kilocalories of the purchased food products. Teenage girls who shopped with a peer in the high-kilocaloric condition purchased higher kilocaloric food products relative to the girls who shopped with a peer in the low-kilocaloric condition. In addition, girls who reported to be hungry purchased higher kilocaloric food products in general. These findings might imply that teenage girls follow unhealthy food purchases of a peer during shopping. Health promotion might benefit from our findings by also focusing on food purchases and not only food intake. [Copyright &y& Elsevier]

Abstract: The objective of this study was to distinguish different types of consumers according to their level of ethnocentrism in relation to the consumption of foodstuffs in central-southern Chile. To do this a modification of the CETSCALE (Consumer Ethnocentric Tendencies Scale) was applied through direct survey of 800 habitual supermarket shoppers in two cities in central-southern Chile. The modified CETSCALE presented a sufficient level of internal consistency and there were three factors which included the 17 items of the scale. Five typologies of consumer with different degrees of ethnocentrism were distinguished by cluster analysis, based on the values of the factors and items in the CETSCALE. The composition of the typologies of consumers were related to the city and zone of residence, age, socioeconomic level, self-declared life-style, ethnic origin, knowledge of the origin of the foodstuffs purchased, frequency of purchase of imported foodstuffs and reasons for rejection in the case of a low purchase frequency. It may therefore be concluded that different levels of ethnocentrism exist in the consumption of foodstuffs, related with some socio-demographic characteristics of consumers and their attitudes to imported foodstuffs.

Abstract: The present study examined whether a high tax on high calorie dense foods effectively reduces the purchased calories of high energy dense foods in a web based supermarket, and whether this effect is moderated by budget and weight status. 306 participants purchased groceries in a web based supermarket, with an individualized budget based on what they normally spend. Results showed that relative to the no tax condition, the participants in the tax condition bought less calories. The main reduction was found in high energy dense products and in calories from carbohydrates, but not in calories from fat. BMI and budget did not influence the effectiveness of the tax. The reduction in calories occurred regardless of budget or BMI implying that a food tax may be a beneficial tool, along with other measures, in promoting a diet with fewer calories.

Abstract: A qualitative study explored factors that influence parents’ food purchasing behaviours in supermarkets and away-from-home settings, particularly the role played by nutrition information. Individual in-depth interviews were conducted with 15 parents of young children in a provincial city in New Zealand. A semi-structured protocol was used to elicit factors influencing food purchases and explore the understanding and influence of existing nutrition labels. Thematic analysis revealed that while parents wish to select good food for their families, practical factors dominate their decisions. Nutrition labels had little reported influence on food choice, largely because parents face competing demands when selecting food for their families. These factors militate against use of detailed nutrition information, especially formats that require considerable effort to comprehend. [Copyright &y& Elsevier]

Front-of-package (FOP) nutrition labels are placed on products to help consumers make healthy food choices. A lab-in-field experiment was conducted to test the effectiveness of two FOP labels in promoting healthy food choices among Dutch consumers, and to examine whether dieters and health conscious shoppers are more likely to use the FOP labels. In addition, it was examined whether the placement of relatively "good" FOP label scores on products might inadvertently lead to increases in serving sizes. Participants (N = 300) consisted of Dutch consumers shopping for groceries in a local supermarket. They were randomly assigned to one of three conditions (Nutri-score, Multiple Traffic Light (MTL) label, or no label control condition), presented with six different (labeled) cereals, and asked to make a choice. Next, participants were shown a product with a relatively good label score and selected their desired serving size. The results show that the Nutri-score promotes choice of the healthiest cereal. Dieting behaviour and health conscious shopping did not moderate this effect, and the labels did not affect serving size selection. Overall, the study provides evidence for the Nutri-score to promote healthy food choices among Dutch consumers. [ABSTRACT FROM AUTHOR]

Nudging and pricing strategies are effective in promoting healthier purchases. However, whether the effects are equal across individuals with different personal characteristics is unknown. This exploratory study aimed to examine differential effects of nudging and pricing strategies on food purchases across individuals' levels of impulsivity, price sensitivity, decision-making styles, and food choice motives. Data from a virtual supermarket experiment where participants were exposed to five study conditions (control, nudging, pricing, salient pricing, and salient pricing with nudging) was used. Participants completed questionnaires assessing their impulsivity, price sensitivity, decision-making styles, and food choice motives. The outcome was the percentage of healthy food purchases. Effect modification was analyzed by adding interaction terms to the statistical models and post-hoc probing was conducted for statistically significant interaction terms. We used data from 400 Dutch adult participants (61.3% female, median age 30.0 years (IQR 24.0)). The effects of the nudging and pricing conditions on healthy food purchases were not modified by impulsivity, price sensitivity, decision-making styles, and the food choice motives 'health' and 'price'. Only the interactions of the food choice motive 'natural content of foods' x pricing (B = -1.02, 90%CI = -2.04; -0.01), the food choice motive 'weight control' x nudging (B = -2.15, 90%CI = -3.34; -0.95), and 'weight control' x pricing (B = -1.87, 90%CI = -3.11; -0.62) were statistically significant. Post-hoc probing indicated that nudging and/or pricing strategies were more effective in individuals who gave lower priority to these food choice motives. The effects of nudging and pricing strategies on increasing healthy food purchasing behaviors, at least in a virtual environment, do not seem to be influenced by personal characteristics and may therefore be implemented as general health promoting strategies., (Copyright © 2021 The Authors.

This field study identified, through observation, child influence on food and beverage purchases within a supermarket, as well as the influence of the children's perceptions of their parents' parenting strategies related to eating behaviors on these purchases. Four supermarkets were recruited to participate and agreed to allow recruitment of parent-child dyads and implementation of data collection protocols within their stores. Parent-child (7-14 yo) dyads were recruited to wear eye-tracking glasses during the supermarket visit, complete separate individual interviews, and have their store receipts scanned. The receipt data provided evidence of what was purchased, including overall purchases, as well as purchases of energy-dense, nutrient-poor foods and beverages. The eye-tracking data, together with the receipt data, identified which items were requested by the child and purchased. The child interviews provided the child's perceptions of parenting strategies (i.e., parental monitoring, control). Seventy-six dyads agreed to participate and completed the study protocols. During most of the shopping trips, items were purchased as a result of child-initiated request interactions. Children's perceptions of their parent's use of monitoring was consistently associated with fewer purchases overall and of energy-dense, nutrient-poor items, and with reduced child influence on what was purchased.
