Negative emotions increase unhealthy eating: Evidence from the Wuhan lockdown during COVID-19.

This paper studies how negative emotions like stress, anxiety, and boredom can affect unhealthy food consumption. Using the Wuhan lockdown as an external shock, we examine the changes in food consumption in a city that was not in lockdown. We applied the difference-in-differences method to a large scanner dataset from a retail monopoly in China. Our findings reveal that negative emotions induced by the pandemic lockdown significantly elevated consumer spending on unhealthy food items such as crisps, sugary beverages, regular soda, and low-alcohol beverages. Notably, the effect of unhealthy food consumption was more pronounced among younger and wealthier demographics. Triggering factors, like information about confirmed new deaths and infections as well as proximity to local hospitals, were found to strongly influence the consumption of unhealthy foods. Overall, the lockdown's impact extended beyond short-term increases in snack consumption to substantial increases in overall dietary and nutritional intake.

How a food scanner app influences healthy food choice.

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

Not All E-commerce Emits Equally: Systematic Quantitative Review of Online and Store Purchases' Carbon Footprint.

Although it has been studied extensively throughout the past 20 years, the environmental impact of e-commerce can still be considered a controversial subject. Particularly for those wondering whether online shopping constitutes a more environmentally friendly alternative to traditional store-based shopping, evidence can be found that quantitatively supports affirmative as well as opposing claims. Findings differ widely because the contexts and assumptions of the studies from which they are drawn differ widely as well. To advance our understanding of this question and inform actions that can actually reduce the environmental impact of shopping, we carried out a systematic quantitative review of environmental impact assessments that compares the carbon footprint of online and store purchases. Based on over twenty scientific studies, we compiled a dataset of 244 purchases, their estimated carbon footprint and information on the contextual, distribution, behavioral, and geographical conditions on which the calculations are based. We conclude from the reviewed studies that online purchases generally generate a lower carbon footprint than store purchases, but only in the case of car-dependent lifestyles, and possibly only because the studies largely overlook transformations in consumer behavior and in the consumption landscape.

Measuring sustainable consumer food purchasing and behavior.

Consumer food purchasing and willingness to adopt a sustainable healthy diet (SHD) is a key factor affecting the sustainability of the entire food system. Studies have developed scales to measure consumer preferences for particular consumption patterns, while others have sought to empirically define the multiple dimensions of a sustainable food system (environmental, social, economic, etc.). This paper builds on these literatures by tracking consumers' SHD behaviors using a large-scale, longitudinal survey of adults in the United States and mapping them onto multiple systems-level indicators. We wanted to know whether consumers interact with the sustainability of their food along the same principles developed by experts. Our study defines 18 food purchasing behaviors that support the sustainability goals of leading scientific institutions, uses factor analysis to identify the unobserved drivers behind these behaviors, and creates SHD scores to investigate their correlations with other consumer characteristics and behaviors. Factor analysis results show consumer food purchasing is motivated by three underlying sustainability dimensions-Economic Security, Socio-Environment, and Nutrition-which are fewer constructs than often defined by academic researchers. SHD scores reveal higher adoption of behaviors that fall under Economic Security relative to the other two dimensions. All three sustainability constructs are impacted by socio-economic and demographic characteristics.

The country-of-origin label impact on intention to consume insect-based food.

The global food consumption scenario and the influence of a country's image on consumer decision-making motivated this research. The global edible insect market is growing, and cultural issues, disgust, and low perception of quality are barriers to consumption. Through an online experiment (n = 194) Brazilian consumers demonstrate that the use of the country-of-origin label (COOL) can result in greater intention and quality expectation regarding a cricket flour. Consumers showed a preference for the flour produced by a positive image country label. Both intention and quality expectation were higher for the cricket flour produced in the United States. Furthermore, the mediation model indicates that quality expectation mediated the effect of COOL on the intention to consume. The results show that even though consumers have created a positive expectation concerning the product, a higher level of neophobia diminished their intention to consume the product and this relates to the aversion and disgust that can exist towards an edible-insect product. The neophobia level can weaken the effect of COOL on intention mediated by quality expectation. The study aimed to contribute to a better understanding of the consumer's perception of an insect-based food and provide insights into variables related to the intention to consume by verifying their contribution to the consumer's behavior.

The gamification of nutrition labels to encourage healthier food selection in online grocery shopping: A randomized controlled trial.

Food purchase choices, one of the main determinants of food consumption, is highly influenced by food environments. Given the surge in online grocery shopping because of the COVID-19 pandemic, interventions in digital environments present more than ever an opportunity to improve the nutritional quality of food purchase choices. One such opportunity can be found in gamification. Participants (n = 1228) shopped for 12 items from a shopping list on a simulated online grocery platform. We randomized them into four groups in a 2 × 2 factorial design: presence vs. absence of gamification, and high vs. low budget. Participants in the gamification groups saw foods with 1 (least nutritious) to 5 (most nutritious) crown icons and a scoreboard with a tally of the number of crowns the participant collected. We estimated ordinary least squares and Poisson regression models to test the impact of the gamification and budget on the nutritional quality of the shopping basket. In the absence of gamification and low budget, participants collected 30.78 (95% CI [30.27; 31.29]) crowns. In the gamification and low budget condition, participants increased the nutritional quality of their shopping basket by collecting more crowns (B = 4.15, 95% CI [3.55; 4.75], p < 0.001). The budget amount ($50 vs. $30) did not alter the final shopping basket (B = 0.45, 95% CI [-0.02; 1.18], p = 0.057), nor moderated the gamification effect. Gamification increased the nutritional quality of the final shopping baskets and nine of 12 shopping list items in this hypothetical experiment. Gamifying nutrition labels may be an effective strategy to improve the nutritional quality of food choices in online grocery stores, but further research is needed.

Why people are bad at leftover food management? A systematic literature review and a framework to analyze household leftover food waste generation behavior.

Food waste is a significant global problem. In the Global North, households are a major driver of food waste generation and also a key enabler of solutions to address the issue. Leftover food management is identified as one of the key areas that can be targeted to reduce food waste at home. Although a large body of literature exists on household food waste and its drivers, managing food leftovers has received less attention. This state-of-the-art review focuses on leftover food management practices with the view of supporting practitioners in designing and prioritizing behavioral interventions to reduce leftover food waste in households. It uses the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework to select articles for the review. Based on 42 primary studies, this systematic review identifies a range of psycho-social, socio-demographic and lifestyle factors influencing leftover food waste generation behavior at home. Moreover, household food handling skills and knowledge, and availability and accessibility to infrastructure facilities affect leftover food waste generation behavior. Based on the synthesized literature, Leftover Food Waste Generation Behavior (LFWGB) Framework has been developed. The framework conceptualizes psycho-social, personal and lifestyle factors driving leftover food management behaviors at home. Reducing food leftovers must be given top priority along with consumer meal planning and food preparation skills in household food waste reduction interventions and campaigns.

Illicit cigarette market in Georgia: potential impacts on smoking prevalence and tax revenues.

OBJECTIVES: This study aims to examine the impact of taxation measures implemented between 2017 and 2019 on the illicit cigarette market in Georgia and to assess the potential effects of its full elimination on smoking rates and tax revenues. STUDY DESIGN: This was a cross-sectional and observational study. METHODS: The study uses the gap analysis method to estimate the size of the illicit market by comparing self-reported cigarette consumption with tax-paid cigarette sales. Potential changes in cigarette consumption are calculated using estimates of price demand elasticity and the price difference between licit and illicit cigarettes. The applicable excise tax is then applied to the estimated change in licit cigarette consumption to determine the potential change in tax revenues. RESULTS: In 2020, illicit cigarettes accounted for 6.4% of the market, which decreased to 0.6% in 2021. Eliminating the illicit cigarette market could potentially reduce the number of smokers by 0.5% in 2020 and 0.1% in 2021. It could also lead to a 2.8% increase in excise tax revenues in 2020 and a 0.2% increase in 2021. The study highlights a notable shift in consumer behavior since 2019 toward smoking roll-your-own (RYO) cigarettes. CONCLUSIONS: Tax increases did not have a significant impact on the size of the illicit market in Georgia. The shift in consumer preference toward RYO cigarettes may explain why the illicit cigarette market did not expand after the tax hikes. However, this shift diminishes the effectiveness of taxation policies in reducing smoking rates and leads to a decline in excise tax collection.

Pre- and post-pandemic seafood purchasing behavior in the U.S.

The global COVID-19 pandemic resulted in an unprecedented economic shock in current times. Previous literature on consumer shopping behaviors during economic downturns is limited, and studies specific to seafood focused primarily on supply-side shocks. A national survey was conducted using an online platform from February 22 to April 6, 2021 that targeted 100 seafood consumers in each of 20 market areas across the U.S. Following data cleaning, 1908 usable responses were obtained. Results documented significant changes in consumer shopping behaviors. Significantly greater percentages of meals (generally and of seafood) were consumed at home and fewer away from home, as expected. Demographic differences were found in shopping behaviors by age, education, income, and gender, but not by ethnic group. Frequency of shopping decreased in 2020, but the expenditure per shopping trip did not, resulting in less overall spending for groceries as compared to 2019. Respondents were less likely to purchase seafood for takeout or for home delivery of prepared meals as compared to general meals because of concerns over quality, freshness, and safety of seafood. Half of respondents consumed approximately the same amount of seafood as before the pandemic; with 31% reporting decreased seafood consumption, and only 19% increased seafood consumption. Thus, study results provide evidence of a pandemic-imposed shift to consuming greater proportions of seafood meals at-home than away-from-home, and not an overall increase in seafood consumption. The choice of species eaten most often did not differ pre- and post-pandemic. Those respondents who reported decreased seafood consumption in 2020 did so primarily because of: 1) its expense, given reduced incomes from working fewer hours or being laid off; 2) unwillingness to prepare fish at home for the smell and "mess", or being uncomfortable preparing it; or 3) simply not preferring or liking seafood well enough to eat it more frequently. Those who reported increasing seafood consumption did so primarily because it was considered to be a healthy food choice. Additional work is needed to further examine consumption and shopping behaviors throughout the recovery in 2021 and 2022.

The Effect of Consumer Confidence and Subjective Well-being on Consumers' Spending Behavior.

The paper focuses on the role of consumer confidence and selected well-being measures in aggregate consumption and in subsets of aggregate consumption on a broad set of 22 OECD countries. Consumer confidence played a positive and statistically significant role in the development of expenditures especially on durable and semi-durable goods and services. The increase in cognitive, affective and eudaimonic measures of well-being, measured by the Cantril ladder, positive and negative affect and freedom to make life choices variables, had negative impact on total consumption and expenditures on semi-durable goods and services. Possible explanations for these estimates are provided in the paper. Based on the purpose of expenditure, consumer confidence was a significant determinant of all expenditures except for unavoidable spending such as food, health, housing, water, energy, and fuel. The subjective well-being indicators showed a negative impact on expenditures on clothing and footwear, recreation and culture, and restaurants and hotels. Possible explanations for the positive and negative effects of subjective well-being measures on consumption, benefits of including the freedom of choice variable, and directions for future research regarding the introduction of understudied variables are discussed.

The Effect of COVID-19 on hotel booking intentions: Investigating the roles of message appeal type and brand loyalty.

The unprecedented global health concerns pertaining to COVID-19 have impacted the hotel industry. In order to ameliorate such concerns, hotels are sending out marketing communication messages. However, whether the messages effectively impact hotel consumers' behaviors is still unknown. To fill this research gap, this study empirically tested the effect that the perceived severity of COVID-19 (PSC) has on hotel booking intentions as well as the roles of message appeal type (rational vs. emotional) and brand loyalty. The data was collected using a scenario-based online survey (n = 311) and analyzed using hierarchical multiple regression. The rational appeal type had a greater positive influence on hotel booking intentions, which suggests that it is preferable for COVID-19 related messages. The results also indicated that PSC had a negative influence on booking intentions for the low loyalty group, and brand loyalty still played a key role even amidst the COVID-19 crisis.

A big data analysis of COVID-19 impacts on Airbnbs' bookings behavior applying construal level and signaling theories.

This study investigates the impact of the COVID-19 pandemic on consumer booking behavior in the peer-to-peer accommodation sector. This study used a dataset composed of 2041,966 raws containing 69,727 properties located in all 21 Italian regions in the pre- and post-COVID-19. Results show that in the pre-COVID-19 period, consumers preferred P2P accommodations with price premiums and located in rural (versus urban) areas. Although the findings reveal a preference for entire apartments over shared accommodation (i.e., room, apartment), this preference did not change significantly after COVID-19 lockdowns. The contribution of this study lies in combining psychological distance theory and signaling theory to assess P2P performance in the pre- and post-COVID-19 periods.

Sweeteners World Trade and Behaviour in the Pandemic. Evidence from Honey Remedies Nexus Mountain Apis Mellifera Product.

The paper proposes a construct for sweeteners (SMH-sugar, molasses, and honey class) consumer behavior, focusing on the mountain Apis Mellifera healing effects and its market. The paper develops three research dimensions, respectively, the importance of the healing properties of SMH products, the consumer behavior of SMH clients, and the world trade of SMH. Apis Mellifera product is considered one of the primary natural prevention and treatment for COVID-19. Presented empirical and experimental studies, respectively, qualitative analysis for Apis Mellifera product, reveal that honey, especially dark honey, presents healing effects. People understand the healing effects of honey in the COVID-19 context, and consequently, honey consumption increased. The forecasting model of the export value, for the 2021-2040 period, takes into consideration the descriptive statistics analysis based on 2001-2020 data. The paper contains relevant data about the SMH class related to statistics of the World Bank, United Nations, Eurostat, International Trade Center, and other sources presented in the paper. Data have been processed into SPSS and Excel, according to ANOVA (descriptive statistics with a focus on frequency analysis) and forecasting analysis. Supplementary Information: The online version contains supplementary material available at 10.1007/s12355-023-01243-6.

Plate waste increases with the number of foods proposed: An exploratory experimental study in adolescents' school canteens.

The objective of this exploratory study was to examine whether the number of foods offered has an impact on plate waste and meal satisfaction in adolescents' school canteens. The plate waste of 247 French students was estimated during two school lunches, the only variation being the number of starters offered (3 versus 6). Plate waste was assessed by the weight of food left on the tray. Students had to complete a short questionnaire regarding their general satisfaction with the meal. The results indicated that limiting the number of starters provided from 6 to 3 choices led to a decrease of Plate waste (-28.1 g) (p < .0001), and a modest increase in Meal satisfaction (p = .02). They suggest that limiting the number of food choices in school canteens reduces plate waste, while not diminishing satisfaction with the meal.

Can in-store interventions reduce the socioeconomic gap in fruit and vegetable purchases in grocery stores? A descriptive study of volume sales from 2012 to 2020 in Norway's largest grocery store chain.

Fruits and vegetable (FVs) consumption is an essential determinant of health, and intake is strongly patterned by socioeconomic status (SES). Inside grocery store interventions have increasingly been explored to promote healthier diets, especially for people with lower SES. This study describes how the supermarket chain Kiwi used a combination of in-store interventions to increase annual sales of FVs between 2012 and 2020. In particular, this study examined how sales developed in counties with different demographic characteristics (e.g., education, income, overweight and obesity, and self-reported FVs consumption level) in order to evaluate whether the effect differs between different populations. The primary outcome measurement was annual volume sales, adjusted for new stores opening and closing during the study period, also called like-for-like sales. The study has used a descriptive study design. The chain used interventions such as better placement, promoting healthy foods, giving out discounts, and placing "on the go" FVs and cups with portioned FVs at the cash registry. Results show that like-for-like volume sales of FVs grew by 34.1% during the study period. The increase was especially strong for vegetables, which increased by 41.8%, compared to fruits and berries, which increased by 25%. Sales increased for all eleven counties in Norway. Using the Spearman correlation, a moderately positive association was found between the number of overweight or obese people in counties and the development in FVs sales. To conclude, in-store interventions positively impacted FVs sales. More research in an experimental context is needed to determine if interventions may reduce the socioeconomic gap in FVs consumption.

A reversal of defaults: Implementing a menu-based default nudge to promote out-of-home consumer adoption of plant-based meat alternatives.

Restaurants are characterized by high levels of meat being consumed in this out-of-home setting, while plant-based meat alternatives remain a niche product, thus preserving a high environmental impact of food consumption. We tested whether subtly re-designing the restaurant menu, so that plant-based meat alternatives were perceived as the default to a greater extent, increased consumer selection of plant-based meat alternatives. Consumers' freedom of choice was preserved by leaving all choice options on the menu. An online experiment in The Netherlands showed that consumers choose plant-based meat alternatives more often relative to meat when the plant-based option is framed as the default. In a field experiment in a Dutch restaurant, we found that the amount of ordered plant-based meat alternative dishes substantially increased relative to an equivalent meat dish when implementing a default nudge (bean alternative: from 8.6% to 80.0%; seaweed alternative: from 16.1% to 58.3%). Thus, re-designing the menu in a way that suggests that plant-based meat alternatives are the default, while preserving autonomous decision-making, is a promising route to promote out-of-home adoption of plant-based meat alternatives in restaurants.

A click too far from fresh foods: A mixed methods comparison of online and in-store grocery behaviors among low-income households.

A recent policy in the U.S. authorized monthly benefits from a nutrition assistance program - Supplemental Nutrition Assistance Program (SNAP) - to be used online to increase grocery access and promote healthy eating. This study examined online grocery attitudes and purchasing behaviors among low-income SNAP-eligible households with young children with and without online grocery experience. An explanatory sequential mixed methods design was used, including a survey informed by the theory of planned behavior (TPB) and focus groups conducted between November-March 2021. In the quantitative phase, 310 Maryland residents completed an online survey assessing TPB constructs (attitudes, social norms, perceived control), and food purchase frequency online and in-store. Subsequently, 42 participated in the qualitative phase. Differences in TPB constructs and food purchases were compared between families with and without online grocery experience. Online food selection and fees were a common obstacle to online grocery purchasing. Families who had purchased groceries online (57%) had more positive attitudes and perceived fewer barriers to online shopping than those who had not. Self-reported frequency of buying fresh produce (OR = 0.34, p < 0.001), meat and seafood (OR = 0.29, p < 0.001), and sweets (OR = 0.54, p = 0.005) were lower online than in-store. Families discussed mistrust of online hired shoppers and fewer impulse purchases online as reasons for less frequent purchases of produce and sweets, respectively. Successful scale-up of the U.S. policy must address barriers to healthier purchasing behaviors to effectively promote equitable food access, such as decreasing delivery fees and improving the online food selection.

Sparking Change: Evaluating the effectiveness of a multi-component intervention at encouraging more sustainable food behaviors.

Facilitating the adoption of more sustainable food behaviors is key in order to reduce pressure on nature and improve public health. Food businesses that interact directly with consumers are well placed to enable a positive change in food behaviors. The present study evaluates the effectiveness of a 9-week multi-component behavioral intervention implemented by a large UK food retailer. Three food behaviors were explored: meat consumption, food waste and scratch cooking. Evaluation methods comprise of surveys issued pre-intervention, at intervention-end and at delayed follow-up (3 months after intervention end), and focus groups where participants were divided according to life-stage (pre-family, family, retired). Results show the intervention mitigated individual barriers to change and had a positive impact on awareness, intention and behavior which lasted beyond intervention-end. Participants reported reducing their meat consumption and food waste and cooking more frequently from scratch. Findings indicate that the online community, 'ask the expert' videos and product samples were the most impactful intervention components, while recipes and cook-alongs were less effective. This study provides an effective and feasible intervention which could be implemented and scaled by food companies. While behavioral interventions offer a positive opportunity for companies to drive consumer behavior change, structural and cultural changes to the food environment will be needed to facilitate long-term change at scale.

Can graphic warning labels reduce the consumption of meat?

The classification of red meat as "probably carcinogenic" and processed meat as "carcinogenic" was followed by pleas to place warning labels, akin to those used for tobacco products, onto meat products. These labels educate people about the health risks associated with the target behavior and are typically accompanied by graphic imagery that elicits disgust (e.g., a picture of blackened lungs). Although the emotion of disgust has been shown to be an effective tool to affect consumer attitudes toward meat, it remains unclear whether such graphic warning labels that recruit disgust would also affect people's intentions to reduce their meat consumption. Two experiments reveal that graphic warning labels, by recruiting disgust, can increase people's intention to reduce their current levels of meat consumption. However, by eliciting disgust, graphic warning labels can simultaneously trigger reactance: graphic images can make people feel they are being manipulated, thereby ironically decreasing meat-reduction intentions. In a final experiment, we aimed to circumvent reactance by providing disgusting information under the guise of trivia, thereby avoiding the perception that the disgusting information was meant to manipulate. Via this route, disgust becomes a potent tool to influence consumers' intentions to consume meat. Ethical concerns are discussed.

Curious to eat insects? Curiosity as a Key Predictor of Willingness to try novel food.

Entomophagy - the consumption of insects - is often rejected by Western society despite its benefits over traditional animal-based proteins. While several factors have been identified as potential predictors of people's willingness to try insect foods, this study introduced an under-explored factor: curiosity, which is a powerful motivator of behaviour that can overcome negative emotions and motivate us to seek new experiences. In two experiments (Ns = 240 and 248), participants (all UK residents, 99.6% British citizens) rated a number of food dishes, half of which contained insects, on a number of factors including curiosity and willingness to try the dish. Across both studies, curiosity predicted willingness to try both insect and non-insect foods above and beyond other factors. Furthermore, we unexpectedly (but consistently) observed a "curiosity-boosting effect" in which curiosity positively interacted with other predictors, increasing their effect on willingness to try insect foods, but not familiar foods. These findings suggest that curiosity promotes the willingness to try insect food in two different manners: A direct effect (above and beyond other factors) and a boosting effect.
