Is it more convenient to waste? Trade‐offs between grocery shopping and waste behaviors

AbstractEfforts to reduce food loss and waste are being made across the supply chain, with households targeted as one of the most wasteful nodes in the chain. In this article, we consider the impact of changing one household food management behavior: grocery shopping. Households that shop more frequently typically incur less food waste. This has resulted in a call for households to adopt a just‐in‐time (JIT) grocery shopping approach, taking smaller trips to the store more frequently. While households may be able to reduce food waste by adopting a JIT shopping approach, their willingness to shop more frequently is less clear. The purpose of this research is to examine the trade‐offs between grocery shopping frequency and food waste behaviors among U.S. households. We employ a choice experiment to determine whether consumers are willing to reduce waste by adopting a JIT shopping approach. We explore heterogeneity across households and consider the potential welfare impacts associated with moving to a JIT model of shopping. Our results indicate that, on average, consumers were averse to adding extra shopping trips to their weekly grocery shopping routines and would need to be compensated to do so (mean: $24/week for one extra trip). Consumers would need to see approximately a 12 percentage point reduction in waste to be indifferent to adding one shopping trip to their weekly routine. Spending more to waste less resulted in more welfare gains, on average, yet there is significant heterogeneity in grocery shopping preferences.

Mapping Downstream Agriculture Supply Chain Before and During COVID-19 Pandemic: Distribution Supply Chain Analysis in West Java, Indonesia

Downstream agriculture supply chain refers to the post-harvest activities to deliver the agriculture products to the final consumers, usually through several actors such as middlemen and/or distributors. The Coronavirus Disease 2019 (COVID-19) pandemic at the beginning of 2020 forces the whole world nations to halt the movement in order to slow down the spread of disease, which affects the supply chain activities. Eating out at the restaurant was prohibited and grocery shopping was limited. The disruption caused the shift in consumer behaviour to the increased use of digital solutions in the supply chain, such as buying agriculture products through e-commerce or using chat messenger to order food instead of coming to the establishments. The pandemic situation forces everyone to adopt the technology and use it in daily activities.

Reorganising grocery shopping practices – the case of elderly consumers

ABSTRACT This paper aims to deepen the understanding of elderly consumers’ grocery shopping practices during Covid-19. Drawing on the shopping-as-practice approach within social practice theory, we show how the practices unfold as the pandemic evolves and the situation of the elderly change, which implies new possibilities and limitations in grocery shopping. Qualitative telephone interviews with elderly consumers were conducted in 2020 and followed up during 2021. By analysing the elderly’s grocery shopping as a social practice, we show how different modes of shopping practices (in-store, online and assisted shopping), came about, how they were reconfigured, and what made them work smoothly or not during the corona pandemic. We also show how the grocery shopping practices, and the modes involved were situated and synchronised in everyday life. The paper also discusses the implication for retailers.

Factors influencing grocery shopping choices and the prevalence of food label use among Saudi mothers: a cross-sectional pilot study

PurposeThere is currently limited data available on the Saudi population’s adoption of nutritional guidelines or on other factors influencing food purchasing behaviors. The purpose of this study is to evaluate the prevalence of nutrition label use, explore factors that could influence food choices during grocery shopping and evaluate the association of these factors with the sociodemographic characteristics of mothers.Design/methodology/approachMothers were recruited at a community event. They were requested to complete a questionnaire that assessed social and lifestyle characteristics as well as product features that influence food choices during grocery shopping.FindingsThe study included 157 mothers. The prevalence of label reading was high with 69% of participants always or mostly reading labels pre-purchase. Features that were most likely to “always” influence purchase choices included: product healthfulness (57.3%), children’s preference (45.9%), specific needs of a family member (38.9%). The feature “awareness campaigns and workshops” was found to be associated with both low and high-income groups. There was a poor understanding of what the “light” food label meant with only 37.6% answering correctly.Research limitations/implicationsFurther research is needed with a higher sample size with diverse sociodemographic characteristics.Practical implicationsSaudi mothers are influenced by product healthfulness as well as children’s and family members’ needs when grocery shopping. There was a high prevalence of reading nutrition labels prepurchase. These findings can inform future public health policy on the main drivers for food purchasing decisions and the need for educational initiatives in Saudi Arabia.Originality/valueThe present research collates factors influencing food choices

Modeling of older adults’ driving exposure and avoidance using objective driving data in a naturalistic driving study

Older adults in the United States rely heavily on driving their own vehicles to commute to work, shop for groceries, and access public services. To effectively help older adults maintain mobility and independence,we need to better understand how thecognitive, visual functioning, and health declines influence their tendency to self-restrict their driving. The objective of this study is to develop a causal model to examine the effects of age, gender, household status (specifically living alone), physical, cognitive, visual abilities, and health status on older adults’ driving mobility in terms of driving exposure and avoidance. Driving exposure was measured by actual driving data, whereas driving avoidance was assessed by both self-report data and actual driving exposure to challenging situations. Structural equation modeling was used to analyze data collectedin the Second Strategic Highway Research Program Naturalistic Driving Study for establishing relationships between the selected factors and mobility. The structural equation model included a total of794 participants aged 65 and over (367 or 46.22%femalesand 427 or 53.78% males). Results indicate that poorer health is associated with less driving exposure; deteriorating cognitive and physical capabilities are associated with more self-reported driving avoidance and less actual driving in challenging situations; visual function is associated with self-reported avoidance; living alone is associated with higher driving exposure in general as well as in challenging situations; self-reported driving avoidance of challenging situations has a negative association with actual driving in those same situations. The final model could be applied to predict older adults’ mobility changes according to their age, gender, household status, as well as their visual, physical, cognitive and health status.

Exploring sense of place in relation to urban facilities – evidence from Lisbon

Urban environments constitute the habitats in which an increasing number of people live. Place-making forms part of this living, occurring in the context of specific urban assemblages made up of facilities that serve different purposes. For example, Soho in London is characterized by entertainment facilities, while large parts of the Ruhr area in Germany are dominated by industrial features. In this article, we explore possible links between exposure to certain urban facilities and sense of place in Lisbon, Portugal. To do so, we use a web mapping-based survey that allows respondents to map and rate meaningful areas. These areas and their assessments are related to points of interest extracted from Google Places in a structural equation model using PLS-SEM. The results show that exposure to everyday urban facilities such as grocery shops is negatively correlated with place identity, while those that represent leisure locations are negatively correlated with place attachment. Both findings suggest that the temporal rhythm of exposure to certain features is an important factor. Methodologically, our study shows that scales differ between place concepts and their associated spatial footprints – an important finding for future studies. We end the article by offering conclusions and policy recommendations.© 2021 Published by Elsevier Ltd.

Integrating the capability approach and technology acceptance model to explain the elderly’s use intention of online grocery shopping

• OGS as a solution to replace elderly’s grocery trips to achieve independent living. • Capabilities approach and technology acceptance model are used to study intention. • The elderly intend to use OGS as their functional ability declines. • Independent living capabilities positively affect elderly's intention to use OGS. • Subjective well-being positively affects the elderly’s intention to use OGS.

Browsing for food: Will COVID‐induced online grocery delivery persist?

The COVID‐19 pandemic altered daily activities. Many consumers reverted to online grocery shopping and home delivery. We analyze factors associated with the decision to grocery shop online and whether this will persist post‐COVID using data collected via a representative online Qualtrics panel in the State of New Jersey (N = 1,419). Around half of respondents either decreased in‐person shopping, increased online shopping, or pursued a combination of both. We used factor analysis to decompose attitudes towards the pandemic, finding that attitudinal responses broke down into ‘fearful’, ‘believers’, and ‘deniers’. Binomial regressions were used to analyze patterns of frequency of grocery shopping during the pandemic and changes in behavior during the pandemic. Results suggest that age, gender, ethnicity, educational attainment, having children at home, and attitudes towards COVID‐19 are likely to influence frequency of online and in‐person grocery shopping. Specifically, being 50 years or older is negatively associated with online grocery shopping. Those who deny COVID‐19 were less likely to decrease in‐person grocery shopping. People who had children at home, who had advanced degrees, or who were of Hispanic origin were more likely to increase online shopping and decrease in‐person shopping during the pandemic. While our results suggest that in‐person grocery shopping will return to prepandemic levels, we found that respondents report some increased persistence in online grocery shopping post‐COVID.

Including Community Voices to Promote Equity in Online Grocery Shopping: Qualitative Findings From SNAP-Eligible Households With Young Children

ObjectivesOnline grocery shopping has grown in popularity among low-income households. Yet, few studies have explored how this service can equitably promote healthy food access and reduce food insecurity and nutritional inequities. Thus, this study explores community-identified recommendations for enhancing online grocery shopping to promote equitable food access. MethodsPrimary food purchasers of Supplemental Nutrition Assistance Program (SNAP) eligible, low-income households with children under 8 years old were recruited via Facebook to participate in audio-recorded focus groups and interviews as part of a larger mixed-methods study (Nov 2020 – March 2021). Participants were asked about their experiences with online grocery shopping, SNAP, and specific recommendations on how both programs could be improved to reduce inequities in food access. Recordings were transcribed and analyzed using an equity-oriented obesity prevention framework centered on 1) increasing healthy options, 2) reducing deterrents, 3) improving social and economic resources, and 4) building community capacity. ResultsA total of 44 primary food purchasers participated in in-depth interviews (n = 5) or one of 11 focus groups of 3–5 people (n = 39). Overall, 31 distinct recommendations emerged, which were grouped into 7 categories. Recommendations targeted four distinct stakeholder groups: grocery delivery service providers (D), grocery stores (G), health educators (H), and policy makers (P). To increase healthy options, participants emphasized improving access to services/foods and flexible methods of receiving groceries (D, G, P); to reduce deterrents through greater control of item selection and enhanced shopper interactions (D, G, P), to improve social and economic resources through more payment options and expanding SNAP eligibility and services (H, P), and to build on community capacity through meal planning support (G, H, P). ConclusionsFindings provide specific, actionable, community-informed trajectories for stakeholders to tailor online grocery shopping services to promote equitable food access for SNAP-eligible, low-income shoppers.

Child’s Acceptance and Readiness to Adhere to a Low-Sugar Diet: Evidence From a Guided Grocery Shopping Pilot for Latinx Adolescents With Non-Alcoholic Fatty Liver Disease

Abstract Objectives High sugar intake has been implicated in hepatic steatosis and metabolic dysfunction. A previous clinical trial among adolescents with non-alcoholic liver disease (NAFLD) demonstrated that replacing household meals and snacks with similar no- or lower-sugar alternatives for 8 weeks resulted in a reduction in sugar intake and hepatic steatosis. This pilot study aimed to assess the feasibility and acceptability of a guided grocery shopping (GGS) intervention, as an alternative to food replacement, to reduce sugar intake among Latino children with NAFLD. Methods After removing foods high in added sugar (>5g of sugars per serving) from the households of nine adolescents with previously diagnosed NAFLD, parent/child dyads were provided dietitian-led personalized nutrition education sessions and assistance with selecting and purchasing weekly groceries low in free sugars (added sugars + those in fruit juice) for the household for four weeks. Children's readiness-to-change was measured at baseline (month 0), upon conclusion of the intervention (month 1), and at long-term follow-up (month 6) using a Likert scale survey based on the Transtheoretical Model, and semi-structured in-depth interview with code-based thematic analysis were used to assess parents and children's perceptions of the intervention. Results Readiness-to-change of participating children (n = 5; age 8 to 15 y) shifted from Contemplation (considering to take actions at a foreseeable future) at baseline to Action (recently achieved behavior change) at both months 1 and 6. A key theme that emerged from the interviews (n = 6, 11 interviews) was the importance of promoting nutrition literacy, particularly by utilizing the nutrition facts label to help identify foods high in free sugars. Changes in the food environment through food removal and low-sugar groceries were also considered acceptable and helpful intervention strategies. Conclusions Dietitian-guided grocery shopping with nutrition counseling following removal of sugary foods from the household was found to be an acceptable intervention strategy to promote a low-sugar diet among adolescents with known NAFLD.

Sociodemographic Factors Associated With Online Grocery Shopping Among Low-Income Households During the COVID-19 Pandemic

ObjectivesThe Supplemental Nutrition Assistance Program (SNAP) Online Purchasing Pilot (OPP) authorized the use of SNAP benefits online in Maryland in May 2020 and expanded rapidly across the US due to the COVID-19 pandemic. We assessed sociodemographic factors associated with online grocery service uptake and current and intended future use during and after COVID-19 among SNAP-eligible households in Maryland. MethodsPrimary shoppers of SNAP-eligible households with children (n = 310) were recruited online to complete a survey on online grocery shopping (Nov. 2020–Jan. 2021), as part of a mixed-methods study. Descriptive statistics and logistic regression (adjusted for sociodemographics and SNAP use) were performed in Stata. A purposefully sampled subset of respondents (n = 42) participated in focus groups or in-depth interviews, which were transcribed and analyzed in MAXQDA. ResultsMost participants (82%) reported receiving SNAP in the past year. Among those who had ever bought groceries online (57%), the majority first ordered groceries online after the OPP. Older age (30–39 or ≥40 v. 18–29) was associated with ever ordering groceries online [aOR: 2.69 (95% CI: 1.40, 5.16); aOR: 2.95 (1.45, 6.00)], as was grocery shopping weekly (v. less often) [aOR: 2.16 (1.26, 3.70)]. Older age groups [aOR: 4.37 (1.26, 15.19); aOR: 3.77 (1.05, 13.56)] and larger households [aOR: 1.28 (1.02, 1.62)] were more likely to have ordered groceries online before the OPP. Participants often cited COVID-19 as a motivator for ordering groceries online in focus groups, and some reported that the OPP influenced both their decision to buy groceries online and where they shopped online. Most participants who had shopped online planned to continue after the pandemic (79%), while 60% of the full sample expected to shop online more often in the next 6 months than at the time of the survey. ConclusionsAlthough most participants who shopped online started after the COVID-19 pandemic began, a high proportion intended to continue shopping online after the pandemic. Our findings suggest that online grocery services will remain an important source of food for SNAP-eligible households, affirming the need for policies that promote equitable access to healthy food online.

Virtual reality based multiple life skill training for intellectual disability: A multicenter randomized controlled trial

• A VR based life skill training was developed, including shopping, cooking, and cleaning tasks. • VR training can improve cooking and cleaning performance. • VR training had better improvement on memory span than traditional training. • IQ is a significant confounder to the outcome. Life skill-based training is essential for intellectual disabled individuals to regain autonomy and social inclusion. Virtual reality (VR) could deliver a nascent application that is more engaging and secure. The objective of this study was to evaluate the training effects of the VR-based multiple life skill training program on life skill performance, self-efficacy, memory, cognitive and behavioral functions via a multicenter randomized controlled trial. A total of 145 intellectual disabled participants were recruited for a randomized controlled trial with three intervention arms: VR ( n = 42); traditional ( n = 53); and control ( n = 50). The life skill tasks for the interventions included 1) grocery shopping, 2) cooking, and 3) kitchen cleaning. Outcome measures were performance scores for the three tasks, self-efficacy scale, digit span score, and Frontal Assessment Battery score, graded by blinded assessors. Before-after effects of each group were evaluated using separated Wilcoxon Signed-rank tests. VR significantly improved cooking, cleaning performance, and memory span, while traditional training significantly improved shopping, cooking, and cleaning tasks. The generalized estimating equation evaluated effects between groups adjusted for age, gender and intelligence quotient (IQ). VR had significantly larger improvement effects in cooking and cleaning than the control group and memory span compared to traditional training and controls groups. IQ appeared to be a significant confounder on the training effect. Future work may consider developing artificial intelligence to customize programs depending on IQ level.

A Healthy Food Prescription Incentive Program for Adults With Type 2 Diabetes Who Are Experiencing Food Insecurity: Protocol for a Longitudinal Qualitative Study

Abstract Objectives Food insecurity is inadequate or insecure access to food due to financial constraints. Individuals experiencing food insecurity tend to have poorer diet quality compared to their food secure peers. Given the importance of maintaining healthful dietary patterns for optimal glycemic control, food insecurity is a considerable barrier to managing type 2 diabetes (T2DM). Healthy food prescription incentive programs aim to reduce such barriers by providing financial incentives to purchase healthy foods. The purpose of this study is to conduct longitudinal qualitative shop-along interviews among adults with T2DM who are experiencing food insecurity. We will explore experiences of redeeming healthy food incentives and factors influencing food purchasing patterns during participation in a healthy food prescription program in Alberta, Canada. Methods The healthy food prescription incentive program consists of two core elements: 1) A one-time healthy food prescription pamphlet outlining an evidence-based healthy dietary pattern; and 2) A healthy food incentive of $1.50/day/household member to purchase healthy foods in participating supermarkets for 6 months. Thirty participants aged 18–85 years will be purposefully recruited from primary care clinics. At baseline and 6-month follow-up, participants will take part in supermarket-based shop-along qualitative interviews. Participants will be asked to complete a usual grocery shop alongside a researcher. Using think-aloud principles, they will be asked to verbalize their thought processes for the shop's duration. Researchers will also collect naturalistic observations of participants, such as consulting nutrition labels. A post-shop interview will be completed to discuss experiences, decision-making rationale, and potential barriers and facilitators to food purchasing. Data will be analyzed iteratively and inductively at each time point. Further, a longitudinal analysis will compare emerging themes and identify changes occurring over time. Results N/A Conclusions This study will generate key data regarding if, how, and why such programs may address barriers to maintaining healthful dietary patterns. These findings will help to understand experiences of participating in healthy food incentive programs that can be used to improve future programs. Funding Sources Alberta Innovates.

Online Grocery Shop

Abstract: Online shopping has been known as a rapidly growing business, and although online grocery shopping has not followed these same growth patterns in the past, it is now being recognized for its potential. As such, the focus of previous online shopping research has seldom encompassed this specific retail market, with the existing studies focusing essentially on consumers’ motivations and attitudes, rather than how consumers actually shop for groceries online. Therefore, this dissertation has the objective of uncovering some of the details of consumer decision making processes for this specific online retail market, details which can help further both academic research and managerial knowledge. The general consumer decision making process is characterized by a pre-decisional, a decisional and a post-decisional phase. All of which were addressed in an exploratory fashion, through a mixed methods strategy which combined both quantitative and qualitative methods of data collection. One of the main results obtained through this study is the complementarity of retail channels - as it was found that online grocery shopping serves essentially for major shopping trips, being complemented with smaller trips to traditional stores.

The genetic technologies questionnaire: lay judgments about genetic technologies align with ethical theory, are coherent, and predict behaviour

BackgroundPolicy regulations of ethically controversial genetic technologies should, on the one hand, be based on ethical principles. On the other hand, they should be socially acceptable to ensure implementation. In addition, they should align with ethical theory. Yet to date we lack a reliable and valid scale to measure the relevant ethical judgements in laypeople. We target this lacuna.MethodsWe developed a scale based on ethical principles to elicit lay judgments: the Genetic Technologies Questionnaire (GTQ). In two pilot studies and a pre-registered main study, we validated the scale in a representative sample of the US population.ResultsThe final version of the scale contains 20 items but remains highly reliable even when reduced to five. It also predicts behaviour; for example, ethical judgments as measured by the GTQ predicted hypothetical donations and grocery shopping. In addition, the GTQ may be of interest to policymakers and ethicists because it reveals coherent and ethically justified judgments in laypeople. For instance, the GTQ indicates that ethical judgments are sensitive to possible benefits and harms (in line with utilitarian ethics), but also to ethical principles such as the value of consent-autonomy.ConclusionsThe GTQ can be recommended for research in both experimental psychology and applied ethics, as well as a tool for ethically and empirically informed policymaking.

Time, the other dimension of urban form: Measuring the relationship between urban density and accessibility to grocery shops in the 10-minute city

Compact settlements take advantage of economies of scale by sustaining a system of high-quality socio-economic services at close proximities. Urban density with a balanced mix of uses also benefits walking and cycling as mobility modes that provide sufficient access to urban amenities, especially when combined with effective public transport. Indeed, walking and cycling can decrease the use of cars for short-distance trips. From this perspective, urban density can help to reduce pollution, optimise energy consumption and decrease infrastructural expenditures while contributing to more attractive urban environments. These ideas have induced a new wave of time geography planning concepts, such as the ‘10-minute city’, to enhance urban sustainability. For these concepts to move beyond visionary narratives, they must be expressed in specific empirical frameworks. Thus, the current research focuses on accessibility to grocery shops, as an essential urban service, in the Stavanger metropolitan area (Norway) using 10 minutes isochrones for walking and cycling. The study integrates open data, GIS network analyses, statistical regressions and bivariate representations of the results. The research estimates the level of serviceability by quantifying the number of shops that are accessible for each location and interrelates this estimation with spatial and population densities. The paper also presents a method to detect spatial inequalities by visualising over/under-serviced areas. This visualisation can become a tool to support strategies to rebalance such imbalances. Moreover, this study offers a practical approach towards the ‘10-minute city’ concept, as it can be adjusted to different isochrones at different spatial scales. In general, this approach can serve both to analyse existing contexts and to model strategies to support sustainability policies, such as urban densification and the promotion of environmental-friendly transport.

Household Food Shopping Locations Beyond Residential Neighborhoods: An Exploratory Study Using a GPS-Based Household Survey

Understanding household food shopping locations is important as it could help policymakers develop effective place-based strategies to improve healthy eating and subsequently improve health conditions. Although a growing number of studies have examined food shopping patterns and their associations with food environment around home locations, evidence on food shopping locations relative to areas beyond residential neighborhoods remains scarce. We aimed to explore spatial dimensions of household food shopping locations relative to home, workplaces, and commuting routes. We defined three buffers to delineate potential food shopping geographies for home, workplaces, and commuting routes. We calculated home–grocery distances and work–grocery distances, and the percentage of grocery shopping locations falling inside each of the three aforementioned spatial units, respectively. Our findings suggest that people were more likely to visit food stores beyond immediate residential areas or workplace areas. They often bypassed the closest supermarkets near home or work, whereas they were more likely to shop along their commuting paths. Our findings provide an example of the uncertain geographic context problem in a context of food activities, highlighting that activity space is a more comprehensive measure for assessing food exposures and food shopping activities. Key Words: activity spaces, food shopping locations, healthy food environment, residential neighborhoods, workplace neighborhoods.

To bike or not to bike: Exploring cycling for commuting and non-commuting in Bangladesh

In recent years, Bangladesh has started moving its transportation vision towards achieving sustainability goals such as increasing bicycle infrastructure, sidewalks, reducing air pollution, etc. To contribute to the ongoing discussion, we explored factors that influence the use of bicycles for different trip purposes in Rajshahi, a medium-sized city in Bangladesh. A face-to-face household survey was conducted to collect individuals’ socio-demographic characteristics, their travel patterns for different trip purposes, and perceptions of the built environment. We developed four Integrated Choice and Latent Variable (ICLV) models to understand the influence of latent perceptions on bicycling for commuting and non-commuting (i.e., grocery shopping, going for tea, and recreational) trips. The analysis indicates that women are more likely to choose a bike for commuting trips but are less likely to use bikes for recreational trips. The results also show that the choice of commuting by bicycle is positively associated with commuting distance and negatively associated with residential land use. Walkability perception has a significant positive association with the choice of bikes for commuting and non-commuting trips. Road safety perception for active travel is positively associated with bike choice for recreational trips, and crime perception of the neighborhood is negatively associated with bike choice for grocery trips. The results from this study will be helpful for policymakers to understand and improve the built environment to attract individuals towards bike use.

Effects of Digital Food Labels on Healthy Food Choices in Online Grocery Shopping.

In order to induce the shift in consumer behavior necessary for the mitigation of diet-related diseases, front-of-package labels (FoPL) such as the Nutri-Score that support consumers in their efforts to identify nutritionally valuable products during grocery shopping have been found to be effective; however, they remain non-compulsory in most regions. Counter-intuitively, a similar stream of research on digital web-based FoPL does not yet exist, even though such digital labels hold several advantages over physical labels. Digital FoPL can provide scalable and personalized interventions, are easier to implement than physical labels, and are especially timely due to the recent increase in online grocery shopping. The goal of this study was to demonstrate the technical feasibility and intervention potential of novel, scalable, and passively triggered health behavior interventions distributed via easy-to-install web browser extensions designed to support healthy food choices via the inclusion of digital FoPL in online supermarkets. To that end, we developed a Chrome web browser extension for a real online supermarket and evaluated the effect of this digital food label intervention (i.e., display of the Nutri-Score next to visible products) on the nutritional quality of individuals’ weekly grocery shopping in a randomized controlled laboratory trial (N = 135). Compared to the control group, individuals exposed to the intervention chose products with a higher nutritional quality (e.g., 8% higher healthy trolley index (HETI), 3.3% less sugar, 7.5% less saturated fat). In particular, users with low food literacy seemed to benefit from the digital FoPL (e.g., 11% higher HETI, 10.5% less sugar, 5.5% less saturated fat). Furthermore, participants exposed to the food label advocated its introduction more strongly than the control group (p = 0.081). Consumers worldwide could easily install such applications to display digital food labels on their end devices, and would thus not have to wait for stakeholders in the food industry to eventually reach consensus on mandatory food label introduction.
