Abstract
Food choice behavior plays a large role in achieving sustainability goals. Meat in particular has a negative environmental impact as compared with plant-based food - and is more frequently chosen in restaurant contexts. To increase plant-based meal choices in restaurants, we tested three nudges for menus that are likely to be implemented by restaurant owners: a hedonic label (e.g., artisanal vegetable burger), a chef's recommendation (specifying the vegetarian option as the chef's favorite), and a salience nudge (a box around the vegetarian option). In an online experiment, we showed participants (n = 513) in four conditions (no nudge, hedonic label, chef's recommendation, and salience nudge) five menus with four meal options each, one of which was vegetarian. We asked participants to choose a meal and subsequently to rate these meals on how tasty and indulgent they were (taste and indulgence attributions). We then revealed which nudge was used to the participants and asked how participants received it. Results show that the hedonic label and chef's recommendation nudge (but not the salience nudge) both increase vegetarian meal choices. The hedonic label increased participants' attributions of indulgence of the meal, but not of tastiness. This finding fits with restaurants' gastronomic, pleasure-seeking context and shapes future directions of labeling interventions, namely that indulgence attributions can be increased in vegetarian foods. Furthermore, the nudges were generally well accepted and participants' intention to return to the (virtual) restaurant was high. Finally, customers expected the hedonic label nudge to be more effective in promoting vegetarian food choices than the other two nudges, partially corresponding with our findings of actual effectiveness.

Screti C, Edwards K, Blissett J. Understanding family food purchasing behaviour of low-income urban UK families: An analysis of parent capability, opportunity and motivation. Appetite 2024; 195:107183.

Abstract
OBJECTIVE Family food purchasing decisions have a direct influence on children's food environments and are powerful predictors of obesity and dietary quality. This study explored parents' capability, opportunities, and motivations regarding food purchasing for their families, as well as barriers and facilitators of healthy food purchasing behaviour, in an ethnically diverse, low-income area. DESIGN Semi-structured interviews with parents of under-11-year-old children were conducted to investigate family food purchases, both when eating inside and outside the home. Interviews were analysed using framework analysis mapped against the COM-B model (Michie et al., 2011). SETTING An ethnically diverse, low-income area in Birmingham, UK. PARTICIPANTS Sixteen parents (13F, 3M) of under-11-year-old children. 75% Pakistani, 12.5% White British, 6.3% White and Black Caribbean, and 6.3% "Other". RESULTS Four themes were identified: i) I know how to provide healthy meals for my family, ii) Family food purchase decisions are complex, iii) I want what they are eating and iv) Healthy eating is important but eating outside of the home is a treat. The barriers of healthy family food purchasing were predominantly at family and community levels, including time, cost, and both parents' and children's food enjoyment and preferences. Facilitators of healthy family food purchasing were primarily identified at an individual level, with high levels of capability and motivation for healthy food provision. CONCLUSIONS Attempts to enhance parental capability to improve healthy food purchasing through nutrition education is not likely to be a useful intervention target in this group. Emphasis on enjoyment, palatability and value for money could be key to increasing parental motivation to purchase healthy family foods.

Abstract
Understanding the mechanisms that underlie desire and intentions may assist in the search for strategies to promote the selection and consumption of more sustainable and healthier products. Therefore, we conducted two experiments to examine how cognitive representations influence desire and intentions for various savoury dishes. In Experiment 1, 1000 participants were allocated to one of five conditions, listing either the typical, sensory, context, hedonic, or health features of 20 popular dishes to assess cognitive representations, before rating their present moment desire to consume each dish. Although there was no direct effect of condition on desire, there was a significant mediating effect of condition on desire through the proportion of consumption and reward features listed (i.e., sensory, context, and hedonic words). In Experiment 2, 892 participants were allocated to one of four conditions, listing either the typical, sensory, context, or health features for the same 20 dishes, before rating their intention to consume each dish over the next four weeks. At a 4-week follow-up, participants rated how often they had consumed each dish. Again, there was no direct effect of condition on intentions, although there was a significant mediating effect of condition on intentions through consumption and reward features. This suggests that mentally simulating a previous consumption experience increases intentions to consume the dish in mind. The results also showed a positive indirect effect of consumption and reward features on behaviour through an increase in intentions. Describing healthy and sustainable products in terms of the rewarding consumption experience may increase desire and intentions to consume them, improving the health of both people and the planet.

Abstract
The school meal system could contribute to the transition towards more sustainable food system by promoting plant-based meals. Knowing whether parents want more vegetarian school meals for their children is a prerequisite for a successful implementation. The present study aimed to estimate the proportion of parents who would opt for more vegetarian school meals for their children and to study associations of willingness with family characteristics and food choice motives. An online survey was sent to parents whose children are registered for school canteen in Dijon (France). We collected child-level information, data on family sociodemographic characteristics, and data on dietary habits and food choice motives of the family. We examined family characteristics associated with the willingness to increase the frequency of vegetarian school meals from one meal per week to two or daily. Generalized linear models were performed. In total, 49% of parents were willing to opt for a second weekly vegetarian meal and 26% for a daily vegetarian meal for their children (n = 1261). Parents willing to opt for more vegetarian meal were more likely to have higher education, be flexitarian or vegetarian and to currently opt for pork-free meals for their children, and their children attended the school canteen less frequently. Environmental motives were positively associated with the willing to opt for a second weekly vegetarian meal; familiarity and sensory appeal motives were negatively associated. Health and animal welfare motives were positively associated with the willing to opt for a daily vegetarian meal and sensory appeal was negatively associated. Increasing the frequency of vegetarian school meals would satisfy a demand expressed by parents but must be accompanied by interventions enhancing pleasure of eating vegetarian meals.

Using Herbs/Spices to Enhance the Flavor of Commonly Consumed Foods Reformulated to Be Lower in Overconsumed Dietary Components Is an Acceptable Strategy and Has the Potential to Lower Intake of Saturated Fat and Sodium: A National Health and Nutrition Examination Survey Analysis and Blind Tasting. J Acad Nutr Diet 2024; 124:15-27.e1. [PMID: 37532099 DOI: 10.1016/j.jand.2023.07.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 07/20/2023] [Accepted: 07/27/2023] [Indexed: 08/04/2023]
Abstract
BACKGROUND Foods lower in saturated fat, sodium, and added sugars (ie, overconsumed dietary components) must have an acceptable flavor profile to promote intake. OBJECTIVE The aim of this research was to model the influence of using herbs/spices as flavor-enhancers when reducing overconsumed dietary components in commonly consumed foods and evaluate acceptance of these flavor-enhanced reformulations. DESIGN Ten leading sources of overconsumed dietary components were identified using the National Health and Nutrition Examination Survey 2015-2018 dietary data. These foods were reformulated to reduce overconsumed dietary components and herbs/spices were used to preserve acceptability. The influence of consumer adoption of the reformulated foods on intake of overconsumed dietary components was modeled using National Health and Nutrition Examination Survey data. Consumer acceptability of the reformulated recipes was assessed with blind taste testing. PARTICIPANTS/SETTING Dietary data from adults aged 19 years and older (n = 9,812) included in the National Health and Nutrition Examination Survey 2015-2018 were used to identify foods for reformulation and model the potential influence of reformulation. The blind taste testing included 85 to 107 consumers per panel. MAIN OUTCOME MEASURES Estimated daily change in total intake of saturated fat, sodium, added sugars, and energy with intake of the reformulated foods instead of the original foods. Consumer ratings of overall liking of the reformulated recipes vs the original recipes were assessed using standard 9-point hedonic scales. STATISTICAL ANALYSES PERFORMED Descriptive statistics with use of survey procedures were used to model the influence of reformulated food adoption. Mixed effect models were used for analysis of the blind tasting data. RESULTS With intake of the reformulated foods, instead of the original versions, by 25% to 100% of current consumers, estimates suggest lowering of saturated fat (25% consumer adoption to 100% consumer adoption -2.9% to -11.4%, respectively), sodium (-3.2 to -11.5%, respectively), and added sugars (-0.5 to -2.7%, respectively) intake. The overall liking ratings for seven of the 10 reformulated foods were superior or at parity with the original foods. CONCLUSIONS This proof-of-concept research suggests that using herbs/spices to create flavor-enhanced recipes lower in overconsumed dietary components has the potential to reduce intake and is acceptable to consumers.

Abstract
Reducing meat consumption is essential to curb further climate change and limit the catastrophic environmental degradation resulting from the current global food system. However, consumers in industrialised countries are hesitant to reduce their meat intake, often because they find plant-based foods less appealing. Despite the climate emergency, eating meat is still perceived as the norm, and recommended in most national dietary guidelines. To support the transition to more sustainable diets by providing insights for increasing the appeal of plant-based foods to mainstream consumers, this review presents recent research findings on how people think and communicate about meat-based and plant-based foods. The key findings we review include: (1) while vegans think about plant-based foods in terms of enjoyable eating experiences, omnivores think about plant-based foods in terms of health, vegan identity and other abstract information that does not motivate consumption in the moment. (2) Packages of ready-meals and social media posts on Instagram present plant-based foods with fewer references to enjoyable eating experiences than meat-based foods. (3) Presenting plant-based foods with language that references enjoyable eating experiences increases their appeal, especially for habitual meat eaters. This language includes words about sensory features of the food (e.g., crunchy, creamy), eating context (e.g. pub; with family) and immediate positive consequences of eating (e.g. comforting, delicious). In contrast, the term 'vegan' is strongly associated with negative stereotypes. Hence, rather than referring to being vegan, meat-free or healthy, the language used for plant-based foods should refer to sensory appeal, attractive eating situations and enjoyment.

Abstract
Nudging consumers towards plant-based foods by making these choices the default option is a promising strategy for effecting sustainable dietary change. In the hypothetical context of online food ordering in a Northern European country, we examined the underlying mechanisms and effectiveness of swapping the default in menus from meat to a plant-based meat alternative. Results showed that pre-selecting a plant-based option in the online setting was not enough to increase choice of plant-based meals alone. Rather, additionally framing the plant-based default as the more sustainable or tasty option was needed to significantly increase choice. While ease was unimportant and held constant in this online setting, endowment and implied endorsement were found to mediate default success such that the positive influence of endowment outweighed the (surprising) negative effect via endorsement. In contrast to general theoretical expectations of default nudges, an endorsement by an online food provider is unlikely to encourage plant-based choices.

Abstract
In two pre-registered experiments, we assessed how people cognitively represent meat and plant-based foods, to examine processes underlying dietary polarization in society. Food descriptions from U.K.-based omnivores (NExp. 1 = 109; NExp. 2 = 436) and vegans (NExp. 1 = 111; NExp. 2 = 407) were coded for features about consumption and reward (e.g., "rich," "indulgent," and "treat") or features independent of the consumption situation (e.g., "healthy," "protein," and "eco-friendly"). Participants used more consumption and reward features for diet-congruent dishes (meat dishes for omnivores and plant-based dishes for vegans) than for diet-incongruent dishes (vice versa). Omnivores focused on abstract, long-term consequences of plant-based foods, whereas vegans focused on the socio-political associations with meat foods. Consumption and reward features also positively predicted attractiveness ratings, the likelihood of ordering a dish, and eating intentions. These findings indicate the cognitive processes of polarized dietary groups that may hinder the mainstream transition to more sustainable food choices.

Abstract
BACKGROUND In today's obesogenic environment high-caloric palatable foods are omnipresent, making it hard for many to reach and maintain a healthy body weight. This study investigates the effects of a health versus hedonic mindset on daily-life snacking behaviour. The hypothesis is that a health mindset leads to reduced snacking behaviour compared to a hedonic mindset. This effect is expected to be most pronounced with high dietary restraint and least pronounced with high trait self-control. METHODS For 3 weeks, degree of craving and amount of snacks that were craved and consumed were assessed four times a day, using smartphone Ecological Momentary Assessment (EMA). A total of 111 female participants (body mass index range: 20-23.5) were randomly assigned to a 1-week health (n = 53) or hedonic (n = 58) mindset, occurring in week 2 of the EMA protocol. The mindset manipulations consisted of text messages, focusing either on the enjoyment of tasty food (hedonic) or on healthy living and eating (health). RESULTS contrary to our hypotheses, mindset did not affect snacking behaviour. Instead, degree of craving and intake of snacks reduced significantly over time, not moderated by mindset, dietary restraint (Restraint Scale) or trait self-control (Brief Self-Control Scale). Importantly, this was not due to reduced compliance. Possibly, the reduced craving and snacking behaviour were due to monitoring and/or socially desirable answering tendencies. Additional time point analyses showed that craving was strongest in the late afternoon (3:30-5:00 PM), and-across mindset conditions-degree of craving correlated negatively with trait self-control. CONCLUSIONS future studies could manipulate degree of monitoring and design individually tailored manipulations.

Abstract
OBJECTIVE Nutrition interventions addressing barriers to healthy eating can mitigate concerns regarding poor diet and obesity among college students. Aimed at reducing healthy eating perceived barriers, this investigation employed two mindset change intervention studies. DESIGN First, a nutrition improvement program called CENTS (Cost of Eating Nutritiously during Time as a Student) that disseminated specific information and utilized experiential activities for mindset change was developed and pilot tested using a pre/post study design. Second, using a similar pre/post method, the CENTS program was evaluated in a quasi-experimental design. MAIN OUTCOME MEASURES We examined perceived barriers to healthy eating (e.g. too costly, too much time), fruit and vegetable consumption, and other variables related to healthy eating (e.g. cost estimates, diet attitudes, self-efficacy, sugary foods consumption). RESULTS Results demonstrated some improvement in many outcomes between the two studies. Most noteworthy, the two major perceived barriers of healthy eating (i.e. too expensive, too much time to prepare) dramatically reduced and cost appraisal accuracy improved. Moreover, some attitudes to eat healthy improved and some unhealthy dietary behaviors reduced. CONCLUSION Using mindset change techniques to address perceived barriers to healthy eating, interventions can promote healthy eating and discourage unhealthy dietary habits among college students.

Abstract
Introduction Increasing obesity rates around the globe have challenged policymakers to find strategies to prompt healthier eating habits. While unhealthy eating takes place in many different contexts, dining out is a context where individuals often choose an unhealthy option despite the availability of healthier alternatives. One possible explanation for this behavior is the unhealthy-tasty intuition, which refers to the belief that unhealthy food is tastier than healthy food. Nevertheless, many policymakers and restaurant managers follow the - in this context - counterintuitive approach of using health claims to nudge people towards more healthy eating choices or habits. Methods The current research employs an online experiment with 137 participants and investigates how health claims and sensory claims impact on the purchase intention of healthy options for desserts. Furthermore, it explores how health inferences and taste expectations mediate the intention to purchase. Results and discussion Findings from the online experiment confirm that health claims prompt positive health inferences, while also stimulating unfavorable taste expectations, resulting in a lower intention to purchase. Surprisingly, we found no effect of a sensory claim on taste expectations. The findings of our experiment contradict the unhealthy-tasty intuition by revealing a significant positive correlation between taste expectations and health inferences. While both health inferences and taste expectations impact positively on purchasing intentions for the health-claim condition, the indirect effect of taste expectations was stronger than the indirect effect of health inferences.

Abstract
Background A large number of deaths could be avoided by improving health behaviours. The degree to which people invest in their long-term health is influenced by how much they believe they can control their risk of death. Identifying causes of death believed to be uncontrollable, but likely to occur, may provide actionable targets for health interventions to increase control beliefs and encourage healthier behaviours. Method We recruited a nationally representative online sample of 1500 participants in the UK. We assessed perceived control, perceived personal likelihood of death, certainty of risk estimation, and perceived knowledge for 20 causes of death. We also measured overall perceived uncontrollable mortality risk (PUMR) and perceived prevalence for each of the Office for National Statistics' categories of avoidable death. Findings Risk of death due to cancer was considered highly likely to occur but largely beyond individual control. Cardiovascular disease was considered moderately controllable and a likely cause of death. Drugs and alcohol were perceived as risks both high in control and low in likelihood of death. However, perceptions of control over specific causes of death were found not to predict overall PUMR, with the exception of cardiovascular disease. Finally, our sample substantially overestimated the prevalence of drug and alcohol-related deaths in the UK. Conclusions We suggest that more can be done by public health communicators to emphasise the lifestyle and behavioural changes that individuals can make to reduce their general cancer risk. More work is needed to understand the barriers to engaging with preventative behaviours and maintaining a healthy heart. Finally, we call for greater journalistic responsibility when reporting health risks to the public.

Abstract
IntroductionDespite the considerable public and planetary health benefits associated with reducing the amount of meat consumed in high-income countries, there is a limited empirical understanding of how these voluntary changes in food choice can be effectively facilitated across different settings. While prior reviews have given us broad insights into the varying capacities of behavior change strategies to promote meaningful reductions in meat consumption, none have compared how they perform relative to each other within a uniform dining context.MethodsTo address this gap in the literature, we synthesized the available research on university-implemented meat reduction interventions and examined the variations in the success rates and effect estimates associated with each of the three approaches identified in our systematic review.ResultsFrom our analyses of the 31 studies that met our criteria for inclusion (n = 31), we found that most were successful in reducing the amount of meat consumed within university settings. Moreover, independent of the number of individual strategies being used, multimodal interventions were found to be more reliable and effective in facilitating these changes in food choice than interventions targeting the choice architecture of the retail environment or conscious decision-making processes alone.DiscussionIn addition to demonstrating the overall value of behavior change initiatives in advancing more sustainable dining practices on college and university campuses, this study lends further insights into the merits and mechanics underlying strategically integrated approaches to dietary change. Further investigations exploring the persistence and generalizability of these effects and intervention design principles are needed.Systematic review registrationhttps://doi.org/10.17605/OSF.IO/DXQ5V, identifier: 10.17605/OSF.IO/DXQ5V.

Abstract
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.

Abstract
BACKGROUND The use of low-calorie menu items as optimal defaults and visual cues may nudge consumers to healthier choices at restaurants. However, little is known regarding their effects on emotions and behavioral intentions, particularly among people with different levels of health concern. OBJECTIVE Evaluate optimal defaults and visual cues' effect on anticipated pleasure and order intention depending upon consumers' health concern level. DESIGN Between-subjects randomized scenario-based experiment. PARTICIPANTS/SETTING In all, 636 US adults recruited through an online crowdsourcing platform in July 2020. INTERVENTION Participants saw 1 of 6 menu boards in a fast-food drive-through simulation. Half the menu boards included meal photos with (1) menu items to be arranged as a combo by choice (ie, create-your-own combo); (2) traditional combos that included high-calorie default items; or (3) optimal combos that included low-calorie default items. The remaining 3 boards were identical without photos. MAIN OUTCOME MEASURES Anticipated pleasure, order intention, and health concern were evaluated with 7-point Likert scales. ANALYSIS Statistical tests included multiple regression, Kruskal-Wallis, χ2, and analysis of variance. Education and sex were tested as potential confounders. RESULTS Optimal combos negatively affected anticipated pleasure (P = .003) and order intention (P < .001) compared with choice combos. Order intention reduction was the same for traditional and optimal combos (P = .128). The presence of photos changed order intention for optimal combos but varied by consumer's health concern level. When health concern was lower, photos decreased the likelihood of ordering the optimal combos (B = -3.06, P = .001), but when health concern was higher, photos enhanced ordering intention compared with the choice group (B = 0.60, P = .001). The photos did not affect anticipated pleasure for any level of health concern. CONCLUSIONS The adverse effect of optimal defaults and how visual cues may reduce their negative effect should be considered in menu design.

The Power of Suggestion: Subjective Satiety Is Affected by Nutrient and Health-Focused Food Labelling with No Effect on Physiological Gut Hormone Release. Nutrients 2022; 14:nu14235100. [PMID: 36501128 PMCID: PMC9740488 DOI: 10.3390/nu14235100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 11/25/2022] [Accepted: 11/28/2022] [Indexed: 12/03/2022] Open
Abstract
Health claims on food labelling can influence peoples' perception of food without them actually eating it, for example driving a belief that a particular food will make them feel fuller. The aim of this study was to investigate whether nutrient and health claims on food labelling can influence self-reported, and physiological indicators of, satiation. A total of 50 participants attended two visits where they were asked to consume a 380 kcal breakfast (granola and yogurt) labelled as a 500 kcal 'indulgent' breakfast at one visit and as a 250 kcal 'sensible' breakfast at the other. The order of the breakfast descriptions was randomly allocated. Participants were unaware that the two breakfasts were the same product and that only the food labels differed. At each visit blood samples were collected to measure gut hormone levels (acylated ghrelin, peptide tyrosine-tyrosine and glucagon-like peptide-1) at three time points: 20 min after arrival (baseline), after 60 min (anticipatory, immediately prior to consumption) and after 90 min (post-consumption). Visual analogue scales measuring appetite (hunger, satiety, fullness, quantity and desire to eat) were completed prior to each sample. Between 60 and 90 min, participants consumed the breakfast and rated its sensory appeal. Participants reported a higher mean change in self-reported fullness for the 'indulgent' than the 'sensible' breakfast from anticipatory to post-consumption (mean difference: 7.19 [95% CI: 0.73, 13.6]; p = 0.030). This change was not observed for the other appetite measures at the other time points or gut hormone levels. This study suggests that nutrient and health claims on food labels may influence satiation as measured by self-reported fullness. It also suggests that the observed differences in satiety scores are not due to changes in the main appetite regulating gut hormones, but are more likely centrally mediated. More high-quality trials are required to confirm these findings.

Abstract
Consumers having a strong unhealthy = tasty (UT) belief are less likely to choose healthy food even though they recognize its health benefits, because they assume healthy food to be unpalatable. The aim of this study was to profile consumers according to their UT belief and specify the strength of the belief among a demographically representative consumer group. The other aim was to investigate the effect of UT belief on expectations of two food products representing either an unhealthy or a healthy image. A total of 1537 consumers participated in the online survey. The scale-based (1-7) mean for UT belief was 3.27 and related positively to male gender and food pleasure orientation and negatively to general health interest. The results indicate that a strong UT belief correlates with positive expectations of unhealthy food and with negative expectations of healthy food. UT belief seemed to increase expected food-associated guilt, but other strong food-related attitudes (health interest with unhealthy food and pleasure orientation with healthy food) reduced this effect. In practice, understanding the relationship between UT belief and personal factors and attitudes, and the importance of this belief to food expectations can assist in finding the tools to encourage consumers towards healthier food choices.

Yang X, Hong M, Shi D, Chen Q. The Negative Effects of Physical Activity Calorie Equivalent Labels on Consumers' Food Brand Evaluation. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:12676. [PMID: 36231976 PMCID: PMC9564542 DOI: 10.3390/ijerph191912676] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/23/2022] [Revised: 09/28/2022] [Accepted: 09/29/2022] [Indexed: 06/16/2023]
Abstract
(1) Background: To prevent excessive caloric intake, a food labeling strategy is widely adopted by governments. Physical activity calorie equivalent (PACE) labels prove to be effective in reducing calorie intake. However, previous literature has mainly discussed the effect of PACE labels on consumers' purchase intention for high-calorie foods but has not analyzed whether consumers evaluate food brands negatively after inhibiting the consumers' purchase intention for high-calorie foods. Therefore, the aims of this study are to explore the negative effects of PACE labels on consumers' food brand evaluation and the underlying psychological mechanism. (2) Methods: This study manipulated the two calorie-information labeling (standard calorie label and PACE labels) in two studies, involving potato chips and chocolate products. It also adopted a prevention focus and anticipated enjoyment of food consumption variables to detect the moderation effects between consumers' promotion focus and PACE labels. (3) Results: Results show that compared with calorie labels, PACE labels have a more negative influence on consumers' food brand evaluation. Furthermore, consumers stimulated by PACE labels develop a stronger prevention focus, thereby reducing their anticipated enjoyment of food brands, and ultimately leading to lower brand evaluations. In addition, when consumers have a promotion focus before choosing food, PACE labels cannot reduce their anticipated enjoyment and food brand evaluation for food brands. (4) Conclusions: While focusing on the negative effect of PACE labels on consumers' purchase intention for high-calorie foods, it should also be noted that PACE labels have a negative effect on food brand evaluation. Therefore, food enterprises should try their best to activate consumers' promotion focus through various environmental cues, so as to avoid a double negative effect on consumers' food purchases and brand evaluations.

Abstract
Ginger has been widely used for different purposes, such as condiment, functional food, drugs, and cosmetics. Gingerols, the main pungent component in ginger, possess a variety of bioactivities. To fully understand the significance of gingerols in the food and pharmaceutical industry, this paper first recaps the composition and physiochemical properties of gingerols, and the major extraction and synthesis methods. Furthermore, the pungency and bioactivity of gingerols are reviewed. In addition, the food application of gingerols and future perspectives are discussed. Gingerols, characterized by a 3-methoxy-4-hydroxyphenyl moiety, are divided into gingerols, shogaols, paradols, zingerone, gingerdiones and gingerdiols. At present, gingerols are extracted by conventional, innovative, and integrated extraction methods, and synthesized by chemical, biological and in vitro cell synthesis methods. Gingerols can activate transient receptor potential vanilloid type 1 (TRPV1) and induce signal transduction, thereby exhibiting its pungent properties and bioactivity. By targeted mediation of various cell signaling pathways, gingerols display potential anticancer, antibacterial, blood glucose regulatory, hepato- and renal-protective, gastrointestinal regulatory, nerve regulatory, and cardiovascular protective effects. This review contributes to the application of gingerols as functional ingredients in the food and pharmaceutical industry.

Abstract
Current levels of meat consumption in Western societies are unsustainable and contribute to the climate emergency. However, most people are not reducing their intake. Here, we examine the language used on social media to describe meat and plant-based foods, since the ways people think and communicate about food could hinder the transition towards sustainable eating. In two pre-registered studies, we analysed the degree to which the language in food posts on Instagram reflects eating simulations, which have been found to be associated with desire for appetitive stimuli. Specifically, thinking about or presenting foods or drinks in terms of rewarding simulations (i.e., re-experiences of enjoying their consumption) has been found to increase their appeal. Here, we analysed the words used in Instagram hashtags (NStudy1 = 852; NStudy2 = 3104) and caption text (NStudy1 = 682) to examine how much they refer to eating simulations (e.g., taste, texture, enjoyment, eating context) or to other food-related features (e.g., ingredients, preparation, health, category information). As hypothesized, meat posts contained more eating simulation hashtags than plant-based and vegetarian posts, which instead contained more eating-independent hashtags, for example referring to health or to vegan identity. Findings for the text words were generally in the same direction but much weaker. Thus, meat food posts contained hashtag language that is likely more appealing to mainstream consumers, because it refers to the enjoyable experience of eating the food, rather than the food being healthy or identity affirming. This pattern reflects polarisation surrounding sustainable foods, which may hinder the shift towards plant-based diets needed to curb climate change.

Abstract
BACKGROUND Effective population-based strategies are required to move towards healthy sustainable diets which replace a proportion of animal- with plant-based protein. Foodservice can support this using a variety of strategies across the food supply chain. OBJECTIVE This systematic review aimed to evaluate the effectiveness of strategies to decrease animal protein and/or increase plant protein in foodservice settings on uptake, satisfaction, financial, environmental, and dietary intake outcomes. METHODS Seven databases were searched in November 2020 with no restriction on study dates to identify peer-reviewed study designs conducted in commercial and institutional foodservices using any strategy to decrease beef, lamb, pork, poultry, eggs, fish or seafood and/or increase legumes/pulses, legume/pulse-based meat substitutes or nuts and reported this review's primary outcome, uptake by consumers either quantitatively or qualitatively. Secondary outcomes were satisfaction and financial, environmental, and dietary intake outcomes. Titles/abstracts then full texts were screened independently by two authors. The Mixed Methods Appraisal Tool was used for quality appraisal. Results were described using a narrative synthesis by strategy type. The protocol is registered with PROSPERO (CRD42021235015). RESULTS From 20,002 records identified, 38 studies met eligibility criteria, of which 16% were high quality. Strategies included forced restriction (n=4), menu re-design (n=6), recipe re-design (n=6), service re-design (n=4), menu labelling (n=7), prompt at point of sale (n=7) and multi-pronged strategies (n=4). Menu labelling, prompting at the point of sale and re-designing menus, recipes, and service increased uptake of target foods in most studies with the largest consistent changes in menu re-design. Few studies explored secondary outcomes. Recipe re-design, prompt at the point of sale and menu labelling strategies that measured satisfaction found a positive or neutral effect. CONCLUSIONS The most promising strategies are likely in menu re-design, followed by menu labelling and service re-design. Satisfaction appears to not be negatively impacted by recipe re-design, prompting at the point of sale and menu labelling. More studies are needed to evaluate financial, environmental, and dietary outcomes.

Abstract
AbstractMemories acquired incidentally from exposure to food information in the environment may often become active to later affect food preferences. Because conscious use of these memories is not requested or required, these incidental learning effects constitute a form of indirect memory. In an experiment using a novel food preference paradigm (n = 617), we found that brief incidental exposure to hedonic versus healthy food features indirectly affected food preferences a day later, explaining approximately 10% of the variance in preferences for tasty versus healthy foods. It follows that brief incidental exposure to food information can affect food preferences indirectly for at least a day. When hedonic and health exposure were each compared to a no-exposure baseline, a general effect of hedonic exposure emerged across individuals, whereas health exposure only affected food preferences for high-BMI individuals. This pattern suggests that focusing attention on hedonic food features engages common affective processes across the general population, whereas focusing attention on healthy food features engages eating restraint goals associated with high BMI. Additionally, incidental exposure to food features primarily changed preferences for infrequently consumed foods, having less impact on habitually consumed foods. These findings offer insight into how hedonic information in the obesogenic food environment contributes to unhealthy eating behavior that leads to overweight and obesity. These findings further motivate the development of interventions that counteract the effects of exposure to hedonic food information and that broaden the effects of exposure to healthy food information.

Abstract
Maintaining a healthy weight is a concern for a large proportion of adults in the UK, with obesity rates having almost doubled between 1993 and 2011. With overweight and obesity linked to several diseases and health conditions, nurses are often tasked with raising the subject with their clients/patients and advising on lifestyle modifications. This article examines ways to identify whether a person needs to lose weight and establishing targets. It then reviews the evidence base for different approaches to weight management currently available and the advice nurses can provide.

Abstract
How do situations influence food desire? Although eating typically occurs in rich background situations, research on food desire often focuses on the properties of foods and consumers, rather than on the situations in which eating takes place. Here, we take a grounded cognition perspective and suggest that a situation that is congruent with consuming a food increases simulations of eating it, which, in turn, affect desire, and the expected and actual liking of the food. We tested this idea in four pre-registered experiments (N = 524). Participants processed an image of a food presented in a congruent situation, an incongruent situation, or no background situation. Compared to the incongruent situation, the congruent situation increased expected liking of the food and desire, and this was partially or fully mediated by eating simulations. The congruent situation also increased salivation, a physiological indicator of preparing to eat. However, there was only weak and indirect evidence for congruence effects on actual liking of the food when tasted. These findings show that situational cues can affect desire for food through eating simulations. Thus, background situations play an important but understudied role in human food desires. We address implications for research using food images, and for applications to promote healthy and sustainable eating behaviour.

Abstract
This article discusses the cognitive mechanisms underlying the motivation to consume sugar-sweetened beverages (SSBs) and outlines implications for developing healthy hydration habits. While the detrimental health consequences of consuming SSBs are well understood, the psychological processes underlying the motivation to consume them are understudied. To address this gap, the current article applies a grounded cognition theory of desire and motivated behaviour, which can be used as a framework to understand and potentially change the motivation for SSBs and healthier alternatives, such as water. The grounded cognition theory of desire argues that people represent foods and drinks through potentially rewarding simulations, or re-experiences, of consuming them. These simulations, in turn, can increase desire and motivated behaviour. In line with this theory, research on eating behaviour shows that people think about attractive food in terms of what it feels like to eat it and in terms of relevant eating situations and that these simulations predict the desire to eat. Similarly, emerging research on SSBs shows that people represent these beverages in terms of the sensory and rewarding experiences of drinking them, more so than water, and especially if they consume them often. These simulations, in turn, predict the desire for sugary drinks and actual consumption. This has implications for attempts to increase healthy hydration: in order to facilitate healthy choices, the immediate pleasure to be gained from consuming a healthy beverage should be emphasized, rather than its long-term benefits. Repeatedly facilitating healthy drink choices in similar situations can ultimately contribute to the development of healthy hydration habits.

Abstract
PURPOSE OF REVIEW To evaluate the multidimensional influence of food environments on food choice, dietary quality, and diet-related health and identify critical gaps necessary to develop effective population interventions that influence food choice. RECENT FINDINGS Multicomponent interventions that interact with multiple layers of the food environment show limited but consistent effects on dietary behaviors and may have wider and substantive population-level reach with greater incorporation of validated, holistic measurement tools. Opportunities to use smartphone technology to measure multiple components of the food environment will facilitate future interventions, particularly as food environments expand into online settings and interact with consumers in novel ways to shape food choice. While studies suggest that all dimensions of the food environment influence diet and health outcomes, robust and consistent measurements of food environments that integrate objective and subjective components are essential for developing stronger evidence needed to shift public policies.

Abstract
Food production--especially raising animals for meat--has a massive negative impact on the environment and contributes to global warming. To address this, we investigated whether information about food sustainability would increase purchases of sustainable foods by patrons of university cafés. In Study 1, patrons were randomly assigned either to see a menu that had sustainability labels indicating the degree of environmental impact of each item, or to see a menu without labels. Women who saw the labels were significantly more likely to purchase sustainable foods, whereas men were not influenced by the labels. In Study 2 we targeted one sustainable menu item (a veggie burger) and, in a 2 (sustainability) x 2 (taste) design, varied whether patrons learned that the veggie burger was especially sustainable or especially tasty. Women were significantly more likely to purchase the veggie burger if they learned it was sustainable or tasty, but again, the manipulations had no effect on men. We discuss why women are more likely to change their food choices to eat more sustainably than are men.

Abstract
Research indicates that most college students are not meeting dietary and physical activity guidelines, and the average student gains an estimated 1.6-3.0 kg during 4 years of study. College administrations are well-positioned to influence student weight-related health behaviours by ensuring that campus environments/policies promote health. However, to date, campus health interventions have largely addressed individual and interpersonal factors rather than environmental/policy-level changes. Using an ecological perspective, this narrative review synthesizes the literature on campus environmental/policy-level factors (e.g., food availability, physical activity requirements) associated with student diet, physical activity and weight, as well as campus interventions to address these factors. Web of Science and PubMed databases were searched between December 2018 and November 2019. Results indicate that campus food environments may contribute to overconsumption and weight gain, and the number of campuses requiring students to participate in physical activity courses is in decline. Eight examples of environmental/policy-level campus interventions are presented: nutrition labels in dining halls, campus-wide healthy choice marketing campaigns, restricted payment methods for à la cart dining, trayless dining, health-themed residence halls, peer health education programmes, active classroom spaces and physical activity course requirements. Implications for research and health promotion programmes/policies in the field of college health are discussed.

Abstract
Plant-based foods are part of a needed change in the food system. This opinion article addresses sustainability, health and consumer issues to inform plant-based food innovation and research. Consumers are key players in the food system. In 2020, consumers require that cues of sustainability be clearly addressed in food innovation. Consumers are more and more conscious of the detrimental effects of animal farming on the environment as well as the ethical issues resulting from poor animal welfare. Consumers want their products to be sustainable, healthy and conscious of animal welfare. Plant-based foods deliver on all fronts. Nevertheless, consumers have to deal with facilitators and barriers towards dietary change such as cooking skills, taste preference and family support.

Nutrition labels' strengths & weaknesses and strategies for improving their use in Iran: A qualitative study. PLoS One 2020; 15:e0241395.

Abstract
BACKGROUND This study aimed to explain the strengths and weaknesses of the Traffic light label (TLL) and nutrition facts label (NFL) and the strategies for improving their use in Iran, based on the perspectives of different stakeholders, including mothers, food quality control experts (FQC), nutritionists and food industry experts. METHODS We conducted 10 Focus Group Discussions (FGDs) with 63 mothers, 10 semi-structured interviews with FQCs, 1 FGD with 6 nutritionists and 1 FGD with 8 food industry experts. To clarify some of the questions that arose from the interviews, the researcher interviewed three policy makers who had sufficient information about the TLL. The discussions and interviews were transcribed verbatim and MAXQDA10 software was used for coding. RESULTS The most important findings of this study based on different stakeholders' perspectives were as follows: mothers believed that nutrition labels reduced the consumption of high-calorie products, although they found the TLL to be easier to understand than the NFL because of its red color. However, their weaknesses were their incompatibility with culture and the lack of trust in the information provided by manufacturers. FQCs pointed out the possibility of changing formulations and the appropriateness of the traffic light for patients, but like mothers, they believed that the labels did not suit the governing culture. Further weaknesses were, misleading the consumer, problems in the colorings reported by different laboratories, and different approaches adopted by regulatory experts. The simplicity of understanding TLL for the general public has been suggested by some nutritionists. Nevertheless, the multiplicity of colors of the TLL was the most important weakness presented by nutritionists and food industry experts and the failure to implement nutrition labels was another issue raised by experts. To improve the use of nutrition labels, notification via media especially television, community education and culture building were suggested by all stakeholders. CONCLUSIONS The findings of this study underscore the importance of implementing the policy of nutrition labeling in Iran. Mothers and nutritionists believed TLL to be more appropriate for the public to understand, however, FQCs and food industry experts believed that NFL was more suitable in guiding consumers toward healthy food choices. Education and information dissemination via media on interpretive TLL may affect consumer behavior toward food purchases.

Abstract
Rapid rate of industrialization has turned our planet around in favor of fast foods, food fraud, food terrorism, food waste, food adulteration, food poisoning, food contamination and food injustice, paving the path for green, smart and organic products. Green foods are grown and harvested in the absence of any form of environmental pollution or harmful conditions. Smart foods are termed to be good for the consumers, farmers and the planet. Organic foods are regarded as “credence goods” because some of the attributes that consumers may consider are neither obvious nor easily verified. Therefore, these three terms are interconnected as they forge a substantive common denominator - healthfulness. The concepts of green, smart and organic (GSO) foods are herein recounted together with their interdependence and relationship to health and sustainability. The processes, policies and global trends of GSO foods were discussed, whilst not undermining the benefits and challenges associated with them.

Abstract
Currently, a great number of people have an unhealthy dietary intake, leading to chronic diseases. Despite the high prevalence of obesity and people being overweight, only a few strategies to promote healthier food products have been proven effective. Therefore, the objective of this study was to test the effect of the presence of health information and its integration into a fast food menu context on young adults’ healthy food choices. An experimental between-subjects design consisting of three conditions—subtle, explicit, and no health information—was conducted among 142 participants aged 18 to 24 (Mage: 21.49, SD = 1.77). The results showed that when health information about healthy products was provided, the level of integration of the information into the menu context had an effect. More specifically, participants exposed to explicit health information about healthy products provided on the fast food menu were more likely to choose a healthy food product compared to participants exposed to subtle integrated health information. No interaction effect for moderating factors was found. In line with the healthy food promotion model, the findings suggest that the provision of explicit health information on healthy products stimulates healthy food choices in a fast food environment.

Abstract
The production of meat is a main contributor to current dangerous levels of greenhouse gas emissions. However, the shift to more plant-based diets is hampered by consumers finding meat-based foods more attractive than plant-based foods. How can plant-based foods best be described to increase their appeal to consumers? Based on the grounded cognition theory of desire, we suggest that descriptions that trigger simulations, or re-experiences, of eating and enjoying a food will increase the attractiveness of a food, compared to descriptions emphasizing ingredients. In Study 1, we first examined the descriptions of ready meals available in four large UK supermarkets (N = 240). We found that the labels of meat-based foods contained more references to eating simulations than vegetarian foods, and slightly more than plant-based foods, and that this varied between supermarkets. In Studies 2 and 3 (N = 170, N = 166, pre-registered), we manipulated the labels of plant-based and meat-based foods to either include eating simulation words or not. We assessed the degree to which participants reported that the description made them think about eating the food (i.e., induced eating simulations), and how attractive they found the food. In Study 2, where either sensory or eating context words were added, we found no differences with control labels. In Study 3, however, where simulation-based labels included sensory, context, and hedonic words, we found that simulation-based descriptions increased eating simulations and attractiveness. Moreover, frequent meat eaters found plant-based foods less attractive, but this was attenuated when plant-based foods were described with simulation-inducing words. We suggest that language that describes rewarding eating experiences can be used to facilitate the shift toward healthy and sustainable diets.

Abstract
How does desire for food and drink arise in the human mind? We suggest that rewarding simulations, which are based on previous experiences, play a key role. In other words, people think about food and drink in terms of what it feels like to consume them, and this leads to desire. We illustrate this with research using behavioral, physiological, and neuroimaging methods. This work shows that food and drink cues (e.g., words, eating contexts, labels) trigger spontaneous eating and drinking simulations (e.g., thoughts about taste, texture, and enjoyment) and that these simulations affect desire and eating experiences (e.g., cravings, salivation, taste ratings). These simulations can be disrupted or diffused through working memory load or through mindfulness, thus reducing desire. We discuss these findings in the context of simulations in motivated behavior more generally and suggest directions for future research.

Abstract
This research sought to understand if physical activity recommendations––an integral component of many interventions aiming to promote physical activity––may have unexpected effects on individuals’ mindsets (in this case about the adequacy and health consequences of their physical activity) that can strengthen or weaken recommendation effectiveness. Participants were students and staff at a U.S. West Coast private university, recruited between 2016 and 2019. Two experiments with one-week follow-up periods investigated the effects of viewing recommendations that prescribe a lower (vs. higher) amount of physical activity and provide a liberal (vs. stringent) definition of what counts as physical activity on individuals’ mindsets about the adequacy and health consequences of their physical activity, as well as physical activity-related self-efficacy, physical activity behavior, and perceived health. Study 1 (N = 157) showed that exposure to low-and-liberal recommendations (vs. high-and-stringent recommendations) caused participants to adopt the mindset that their physical activity was more adequate, which in turn predicted greater engagement in physical activity and perceived health one week later. Study 2 (N = 272) showed that regardless of definition of physical activity (liberal vs. stringent), a lower (vs. higher) amount of recommended physical activity led participants to adopt the mindset that their activity was more adequate. This more adaptive mindset predicted greater self-efficacy and engagement in physical activity in the following week, in addition to better perceived health. Rather than inducing complacency, recommendations prescribing a relatively lower (vs. higher) amount of physical activity may be more effective at promoting physical activity and health by inducing adaptive mindsets.

Abstract
Healthy food labels tout health benefits, yet most people prioritize tastiness in the moment of food choice. In a preregistered intervention, we tested whether taste-focused labels compared with health-focused labels increased vegetable intake at five university dining halls throughout the United States. Across 137,842 diner decisions, 185 days, and 24 vegetable types, taste-focused labels increased vegetable selection by 29% compared with health-focused labels and by 14% compared with basic labels. Vegetable consumption also increased. Supplementary studies further probed the mediators, moderators, and boundaries of these effects. Increased expectations of a positive taste experience mediated the effect of taste-focused labels on vegetable selection. Moderation tests revealed greater effects in settings that served tastier vegetable recipes. Taste-focused labels outperformed labels that merely contained positive words, fancy words, or lists of ingredients. Together, these studies show that emphasizing tasty and enjoyable attributes increases vegetable intake in real-world settings in which vegetables compete with less healthy options.
