Abstract
Before developing new meat reduction interventions to support increased sustainability, it is important to understand the motives, diets and preferences of consumers who have already made efforts to reduce meat consumption. While self-declaration has been typically used to identify meat reducers, food frequency data suggests some reducers still identify as omnivores, here termed transitional meat reducers. We compared these "transitional" meat reducers to self-declared meat reducers, unrestricted omnivores and vegetarians/vegans for differences in diet, motives for reducing meat, and perceived barriers to consuming more legumes (dried beans, peas or lentils) and plant-based meat alternative products (PBMAs). We also compared their intention to choose four specific entrees where legumes or PBMAs had partially or fully replaced meat. A convenience sample of Canadian university students completed an online survey (N = 438). 34% of participants were self-declared meat reducers, 16% transitional meat reducers, 33% unrestricted omnivores and 16% vegetarians/vegans. Frequency of eating red meat differed, with self-declared meat reducers eating red meat less often than either transitional meat reducers or unrestricted omnivores. Motives for meat reduction were similar in the two reducer groups. Transitional meat reducers reported significantly more frequent consumption of other protein foods and more barriers to legumes but not PBMA, than either unrestricted omnivores or self-declared meat reducers. Lastly, intention to consume all versions of entrees was very similar in both reducer groups, but with increased preference for full vs partial substitution among self-declared reducers. Transitional meat reducers may be a distinct group for meat reduction interventions compared to omnivores or self-declared reducers.

Abstract
Meat production and consumption are sources of animal cruelty, responsible for several environmental problems and human health diseases, and contribute to social inequality. Vegetarianism and veganism (VEG) are two alternatives that align with calls for a transition to more ethical, sustainable, and healthier lifestyles. Following the PRISMA guidelines, we conducted a systematic literature review of 307 quantitative studies on VEG (from 1978 to 2023), collected from the Web of Science in the categories of psychology, behavioral science, social science, and consumer behavior. For a holistic view of the literature and to capture its multiple angles, we articulated our objectives by responding to the variables of "WHEN," "WHERE," "WHO," "WHAT," "WHY," "WHICH," and "HOW" (6W1H) regarding the VEG research. Our review highlighted that quantitative research on VEG has experienced exponential growth with an unbalanced geographical focus, accompanied by an increasing richness but also great complexity in the understating of the VEG phenomenon. The systematic literature review found different approaches from which the authors studied VEG while identifying methodological limitations. Additionally, our research provided a systematic view of factors studied on VEG and the variables associated with VEG-related behavior change. Accordingly, this study contributes to the literature in the field of VEG by mapping the most recent trends and gaps in research, clarifying existing findings, and suggesting directions for future research.

Abstract
The purpose of this study was to examine emotional and liking responses to foods designed for older adults and made using microwave-assisted thermal sterilization technology (MATS). Six chicken pasta meals (three each with and without herbs) were formulated with three concentrations of salt at 100%, 75%, and 50%. Seventy-six community-dwelling older adults conducted sensory and emotional evaluations. Sensory testing involved measuring liking of various sensory attributes using a 9-point hedonic scale, Just-about-right scales to measure appropriateness of the intensity of the attributes, and check-all-that-apply questions to identify perceived flavor and texture attributes. EsSense25 methodology was used for capturing food-evoked emotional responses. Significant differences existed in all measured sensory attributes and in 14 out of the 25 tested emotions across the six meals. Liking scores for all pastas with herbs and high salt pasta with no herbs were not significantly different for all tested attributes and fell between neither like nor dislike and like slightly on the 9-point hedonic scale. These samples were also associated with positive emotions related to energy and activation. Low-salt pastas with no herbs were consistently the least liked samples and evoked negative emotions. Results show that sodium content can be reduced by up to half when herbs are added to microwave-processed pasta meals without compromising liking. PRACTICAL APPLICATION: Chicken pasta meals manufactured using microwave-assisted thermal sterilization technology are acceptable to community living individuals 60 years and older. Emotional responses to the meal are positive. When formulating these meals, herbs can be added to lower sodium content formulations to improve liking and increase the number of positive emotions associated with the meal. Microwave-assisted thermal sterilization, sodium reduction, emotional responses, consumer liking, older adults.

Abstract
Reducing the consumption of meat constitutes an important part of the global shift towards more sustainable food systems. At the same time, meat is firmly established in the food culture of most human beings, and better understanding of individual behaviors is essential to facilitate a durable change in contemporary eating patterns. To determine the level and nature of attachment to meat among consumers, the Meat Attachment Questionnaire (MAQ) in relation to the phases of behaviour change in the meat consumption reduction process was utilised. Data collected through a survey carried out among Poles aged 25-40 years living in cities were analysed with the use of Spearman's correlations and one-way ANOVA with Tukey's post-hoc tests. The biggest share of the studied group of millennials (N = 317) never considered reducing their meat consumption (Phase 1-41%) and was described by the highest level of MAQ score in all its categories: hedonism, affinity, dependence, and entitlement. More than half of the respondents in Phase 2 participants ("planners") declared a willingness to cut down meat consumption but had not yet put their intentions into practice. Respondents qualified in Phase 3 declared the highest willingness to reduce meat consumption and were significantly less attached to meat regarding all MAQ categories than respondents in Phase 1. The 9% of the study participants (Phase 4) had already limited the frequency of their meat consumption to "several times a week", this however still remains insufficient compared to the ambitious goals of sustainable healthy diets. Results indicated that meat attachment categories, especially hedonism and dependence, were identified as predictors of willingness to reduce meat consumption. Research exploring the determinants of change and possibilities of effective communication about meat reduction on an individual level in different cultural settings are needed.

Abstract
Edible insects recycle food waste, which can help feed a hungrier planet by making food systems more circular and diversifying protein production. The potential for entomophagy (i.e., insect cuisine) to contribute to waste recycling and lower input food production is only beginning to be explored in the U.S., although insects have been consumed by people for millennia in a wide range of cultures. In this perspective piece, we consider as a case study the potential for university foodservice programs in New England to serve as incubators for circular entomophagous food systems. Students are likely early adopters of entomophagy because they increasingly demand sustainable non-meat protein options. University foodservices meanwhile purchase large amounts of food wholesale from local producers, utilize standardized pre-processing, and generate consistent waste streams which may be valuable feed for local insect farmers. Current Farm to Institution approaches strengthen regional food systems by connecting small farmers with university foodservices; we argue that a similar model (Farm to Institution to Farm) could support establishment of local insect farms, introduce edible insects to a relatively receptive base of university student customers, and provide a more sustainable mechanism for repurposing university food waste as insect feed. But to enable this type of food system, additional requirements include: (1) research on domestication of native insect species; (2) investment in processing capacity, ensuring new insect farmers have reliable markets for raw insect products; (3) infrastructure to recirculate waste streams within existing food systems; and (4) creation of recipes that entice new insect consumers.

Effectiveness of strategies to decrease animal sourced protein and/or increase plant sourced protein in foodservice settings: a systematic literature review. J Acad Nutr Diet 2021; 122:1013-1048.

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
A reduction of meat consumption and shift to plant-based diets, especially in industrialized countries, is acknowledged as crucial for reaching climate targets, addressing public health problems, and protecting animal welfare. While scholarly research distilled drivers of meat consumption and barriers to its reduction, insights into the effectiveness of measures to initiate such a profound change in consumer behaviour are relatively scarce. This paper presents a systematic literature review on consumption-side interventions in the context of meat consumption across scholarly disciplines. Our analysis confirms that existing research predominantly assessed interventions addressing personal factors of behavioural change such as knowledge and emotions. Whether these interventions are effective depends on whether information (i) is provided on health, animal welfare or environmental effects, (ii) is emotionally or cognitively framed, and (iii) is aligned with consumers' information needs. Moreover, linking meat to living animals or to the humanness of animals activates negative emotions and, thus, reduces meat consumption. Further, increasing the visibility and variety of vegetarian dishes in food environments decreases meat-eating. Also, educational courses on how to shop and cook vegetarian food are effective in reducing meat consumption. There is less evidence on the effectiveness of interventions addressing socio-cultural factors such as social norms. Regarding future research directions, existing research mainly investigated the influence of interventions on attitudes and behavioural intentions. Hence, there is still a need for studies to assess more long-term effects of intervention measures on actual meat consumption and their potential to initiate fundamental changes in dietary habits.

Abstract
Life cycle assessments (LCA) often highlight the environmental and health benefits for consumers if western diets substitute red meat. However, the specific trade-off consumer face when asked to substitute a red meat dish is scarcely researched, often neglecting the bouquet of substitution options and/or the price component involved. Four substitution strategies are evaluated within an individually adapted choice based conjoint: the substitution by (1) the same red meat dishes with a halved meat portion size, (2) novel plant-based products that mimic the functionality and taste, (3) authentic plant-based components that just mimic the functionality, and (4) vegetarian dishes that just neglect the meat component if still familiar to consumers. The analysis is executed for three popular red meat dishes to account for consistency across meal scenarios, namely Meatballs, Spaghetti Bolognese and Sausage Buns. The analysis is sensitive to red meat consumption habits to better understand the preferences of consumers that can actually substitute a red meat intake.

Abstract
Many people agree that reducing the consumption of meat has good ends (e.g., for animal welfare, the environment, and human health). However, the question of which advocacy strategies are most effective in enabling wide-spread meat reduction remains open. We explored this by prescribing four different meat reduction diets to omnivorous participants for a seven-day adherence period, and studied their meat consumption over time. The diets included a Vegetarian diet, and three flexitarian diets (Climatarian - limit beef and lamb consumption; One Step for Animals - eliminate chicken consumption; Reducetarian - reduce all meat consumption). Results showed pronounced differences between groups in meat consumption during the adherence period, where the Vegetarian group ate significantly less meat than the flexitarian groups. All groups decreased their meat intake in the weeks following the adherence period compared to baseline, however, there were no significant group differences in the level of decrease over time. Participants also changed their attitudes toward meat and animals from pre-to post-intervention, and decreases in commitment toward and rationalization of meat-eating partially mediated change in meat intake. These findings reveal that the diet assignments had some impact on participants' meat consumption and attitudes even after the prescribed adherence period had ended. However, the sustained decrease in consumption did not vary depending on what meat reduction strategy was originally used.

Abstract
American adults consume excess added sugar and saturated fat, and not enough fruit. A possible solution is the "Dessert Flip," a shift in which the proportions of more sustainable plant-based garnishes, such as fruit and nuts, are increased, while the proportion of conventional dessert is reduced. We hypothesized that the pleasing properties of fruits and nuts-color, variety, flavor, and texture-would allow the Dessert Flip to be liked as well or better than a conventional dessert by college-aged students in a dining hall. In a sensory test, participants (n = 118) significantly preferred plated flipped desserts-those containing 80% by weight fruit (strawberries, raspberries, blueberries, and mangoes) and nuts with 20% cake-over the conventional versions of those desserts with 80% cake and 20% fruit and nuts. No significant differences were found in overall liking. In a second experiment, after eating an entrée, participants (n = 150) chose pictures of multiple varieties of flipped cakes with 60% fruit and 40% cake significantly more than pictures of conventional 80% cake for dessert. Based on the U.S. average fruit prices, the Dessert Flip can be equal or lower in price per serving compared to an ungarnished typically sized cake. We conclude that the Dessert Flip offers a feasible option for increasing servings of fruits and nuts in desserts as well as reducing added sugar and saturated fat while maintaining sensory appeal. Future dietary guidelines could include this general strategy as a recommendation for helping adults include more fruits in their diets. PRACTICAL APPLICATION: The Dessert Flip offers an appetizing way for foodservice to promote healthier eating by increasing servings of fruits and nuts in their desserts while reducing added sugar and saturated fat. Consumers can try this strategy at home by cutting a smaller piece of cake and adding fruit on the side.

Abstract
Fish has several benefits that make it a desirable part of a healthy diet. It is also a high-protein product that can be used as a relatively efficient meat replacer. Both from a health and sustainability perspective, however, it is important to consider the optimum number of fish servings per week and to examine whether fish and plant protein can be brought under the same heading of alternative protein sources. To explore the consumer perspective on these issues, this paper draws on a brief literature study and a re-analysis of survey data from the Netherlands collected earlier. The hypothesis was that affinities with fish consumption and plant-based protein sources are to a certain extent related to each other, based on common relationships with food involvement, which set them apart from meat. The results showed that the hypothesis needed to be nuanced: fish consumption was associated exclusively with affinity with spicy meals based on authentic plant protein sources (e.g. nuts) and this relationship was partially based on food involvement. The results are in line with current Dutch recommendations that encourage consumers to eat one serving of fish per week and that stimulate those who already eat more than one serving of fish to replace the rest by plant-based protein sources.

[PMID: 32776553 PMCID: PMC7540316 DOI: 10.1111/1750-3841.15354] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 05/19/2020] [Accepted: 06/15/2020] [Indexed: 11/30/2022]
Abstract
We tested the hypothesis that reduced-salt versions of four "better-for-you" dishes enhanced with monosodium glutamate (MSG) through a "Salt Flip" in an amount that still substantially reduced total sodium matched the consumer acceptance of normal-salt versions. Three versions each-standard recipe with normal salt, reduced salt, and reduced salt with MSG, of four dishes-roasted vegetables (RV), quinoa bowl (QB), savory yogurt dip (SD), and pork cauliflower fried rice (CR) were evaluated by 163 consumers for overall liking and liking of appearance, flavor, and texture/mouthfeel on the nine-point hedonic scale, preference, adequacy of flavor, saltiness, and aftertaste on just-about-right (JAR) scales, likeliness to order, and sensory characteristics by check-all-that-apply. For each dish, the MSG recipe was liked the same (or significantly more for SD, P < 0.05) than the standard recipe, and better than the reduced salt recipe for QB and CR. The same was true of likeliness to order. MSG recipes of QB and SD were significantly preferred to the standard recipes, with no difference for RV and CR. MSG recipes were consistently described as "delicious," "flavorful," and "balanced." Penalty-lift analysis showed that "delicious," "flavorful," "balanced," "fresh," and "savory"; and "bland," "rancid," and "bitter," were positive and negative drivers of liking, respectively. Two of three uncovered preference clusters, accounting for 68% of consumers, consistently liked MSG recipes, and the same or more so than standard recipes. We conclude that MSG can successfully be used to mitigate salt and sodium reduction without compromising consumer acceptance of better-for-you foods. PRACTICAL APPLICATION: The Salt Flip offers a promising dietary sodium reduction strategy through the addition of monosodium glutamate (MSG) to reduced-salt, savory, better-for-you foods that does not compromise consumer acceptance of their sensory profile.

Increasing Vegetable Intake by Emphasizing Tasty and Enjoyable Attributes: A Randomized Controlled Multisite Intervention for Taste-Focused Labeling. Psychol Sci 2019; 30:1603-1615. [PMID: 31577177 PMCID: PMC6843749 DOI: 10.1177/0956797619872191] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2018] [Accepted: 07/29/2019] [Indexed: 01/11/2023] Open
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.
