Examination of students' willingness to change behaviour regarding meat consumption

Sociodemographic and behavioural determinants of vegetarian main dish selection in a French university cafeteria: A three-month observational study with repeated measures

Reducing meat consumption is crucial for improving population and planetary health. Millions of students regularly eat at university cafeterias, which offer a unique opportunity to promote meat-free meals to new generations by addressing barriers such as accessibility, price, and cooking skills. This study aimed to analyse the individual characteristics associated with the proportion of vegetarian main dish choices in a university cafeteria and to determine whether this behaviour influenced the nutritional quality and environmental impact of student meals. A sample of 257 French students who ate regularly at a large university cafeteria took part in an observational study with repeated measures. They took pictures of their meal trays each time they ate at the cafeteria for three months. They completed an online questionnaire to assess their sociodemographic characteristics and various behavioural determinants of the choice of a vegetarian main dish based on the Capability, Opportunity, Motivation Behaviour (COM-B) framework. Being a woman was the only sociodemographic characteristic significantly associated with more frequent vegetarian main dish selection. The proportion of vegetarian choices was negatively associated with attachment to meat (p < 0.001, η2 = 0.189) and positively associated with environmental knowledge (p = 0.034, η2 = 0.018) and the following food choice motives: animal welfare (p < 0.001, η2 = 0.062), health (p < 0.001, η2 = 0.044), ethics (p = 0.002, η2 = 0.039), natural content (p = 0.010, η2 = 0.026), religion (p = 0.014, η2 = 0.025), and mood (p = 0.022, η2 = 0.020). Students who chose vegetarian main dishes more frequently composed healthier (p = 0.023, η2 = 0.020) and more environmentally friendly meal trays (p < 0.001, η2 = 0.349). These findings highlight the variability in the students' propensity to choose vegetarian main dishes in a university cafeteria and its association with motivational factors in a food environment bound by design.

Untangling the dairy paradox: How vegetarians experience and navigate the cognitive dissonance aroused by their dairy consumption

Most people eat meat, yet report valuing the environment, animal life, and their health, which contradicts this dietary behaviour. The psychological discomfort aroused by this value-behaviour inconsistency, and the strategies meat eaters use to resolve this unpleasant state, is termed the 'meat paradox'. Vegetarians eschew meat consumption, but the negative implications of dairy are comparable to meat. We investigated the 'dairy paradox' in a sample of vegetarians (N = 378) using an experimental design. Specifically, we tested whether vegetarians experienced cognitive dissonance after reading about the environmental, animal welfare, and health impacts of dairy consumption when compared to a control group not exposed to this information. Then, we examined to what extent perceiving dairy consumption as Natural, Necessary, Normal, Nice, or Neglectable, and denial of cows' mental states (Experience or Agency) predicted reduced cognitive dissonance. Vegetarians in the dissonance-induction condition reported experiencing significantly greater dissonance, though they more strongly rejected the justification strategies. Instead, they reported greater intentions to reduce their dairy consumption than vegetarians in the control condition. Rather than replicating findings from the meat paradox literature, these results suggest that vegetarians respond to uncomfortable feelings about their value-behaviour conflict with a greater intention to abandon the incongruent behaviour, rather than endorsing the cognitions that justify it. This research provides evidence that vegetarians experience a dairy paradox. Given the success of our study in shifting participants away from behavioural justification and toward behavioural change intentions, our findings can help guide the design of interventions seeking to reduce dairy consumption.

Plant-based Meat Analogs: Perspectives on Their Meatiness, Nutritional Profile, Environmental Sustainability, Acceptance and Challenges

PURPOSE OF REVIEW

Plant-based meat analogs (PBMAs) have been the subject of interest over the past few years due to consumers' demand for environmentally friendly, healthful, and non-animal-based foods. A better comprehension of the composition, structure, texture, nutrition, and sustainability of these PBMAs is necessary.

RECENT FINDINGS

This review articulates the protein sources and composition of PBMAs and their "meatiness" with respect to texture, structure, and flavor enhancement. The components used in the analogs, such as unsaturated fats, fibers, vitamins, minerals, carbohydrates, and plant-based oils enriching their nutritional profile, are described. The study identifies the environmental and sustainability impact of PBMAs, as crucial to the survival and maintenance of biodiversity. More studies are warranted to scope and underscore the significance of the analogs and comprehend the texture or structure-function relationships. Further product development and testing thereof may ultimately result in quality meat analogs that respect meat taste, health and acceptance of consumers, environmental sustainability, animal welfare, and current challenges.

Gradual behaviour change towards meat reduction revisited: Applying the decisional balance scale in a Dutch study

Meat moderation is needed to mitigate climate change and to address issues related to animal welfare and public health. Yet little is known on the process that consumers go through towards meat-reduced diets. Strässner and Hartmann (2023) recently developed the decisional balance scale (DB scale) for meat reduction, in order to get a better understanding of the trade-offs that consumers encounter in this dietary shift. The current study sets out to replicate their German study in the Dutch context. A survey has been conducted among a representative sample of Dutch adults (N = 1982). Overall, the present study corroborated Strässner and Hartmann's findings. Similar to the German situation, Legitimation is the most important barrier, and the Downsides of factory farming is the most important motivator for meat reduction in the Netherlands. The present study extends the German study by comparing the DB scale with other established scales in research on meat reduction. Although several motivational elements related to the legitimacy of eating meat, health impact and production of meat appear in different instruments, the DB scale sets itself apart in adding practical elements (feasibility). Finally, the insights in the decision balance of population subgroups at different stages of behaviour change (no intention, intention, performing) showed that the further in the meat reduction process, the more the pros outweigh the cons. With this, the current study provides valuable insights in bolstering consumers in meat moderation. Our findings support the idea of a gradual shift and reveal that there is potential for acceleration in behaviour change towards meat reduction to be found in adjusting the self-evidence of high-intensity livestock farming systems and the meat-centric food consumption culture.

How Do Greeks Feel about Eating Insects? A Study of Consumer Perceptions and Preferences

Edible insects are considered among the most promising sustainable sources of protein to address the predicted deficiency of conventional food protein. Due to their nutritional and environmental benefits, there is an increasing interest in the ways insects could become part of the Western diet. Little is known about Greek consumers' attitudes toward the habit of consuming insects as food. This study provides insight into Greek consumers' preferences for insect-based food products. The data were collected through an online questionnaire (n = 1531). A two-step cluster analysis and a categorical regression were employed to classify the respondents into discernible clusters and determine the relationship between their socioeconomic characteristics and their willingness to adopt insect-based food products. Feelings of disgust and rejection were the predominant reactions to the concept of insects as food. The acceptance of novel foods derived from edible insects could be potentially enhanced by providing information regarding their positive effects, using familiar food products, and decreasing the insect's degree of visibility by employing processed forms. Finally, the categories of insect protein-enriched food products (bakery, meat, snacks) that Greek consumers are more likely to consume were revealed. Such findings may be useful for promoting strategies regarding consuming insect-based products.

Socio-behavioural factors influencing meat intake and meat reduction intention in Vietnam and Switzerland

Meat consumption is declining in developed countries but increasing in emerging countries. This study, for the first time, compares the socio-behavioural factors influencing individuals' meat consumption level and meat reduction intention between Vietnam, an emerging economy and Switzerland, a developed country. Online consumer surveys were conducted in late 2022, yielding 552 usable replies from Switzerland and 592 from Vietnam for this study. Drawing upon an extended Protection Motivation Theory and using structural equation modelling, we found similarities as well as differences in the determinants of meat consumption behaviour. Perceived health risks of meat overconsumption, self-efficacy of meat reduction, attitude toward ethical and environmental issues, and pressure from family members' reluctance to change diet drove the intention to reduce meat in both countries. Meat attachment emerges as the most important determinant of meat consumption level in not only Switzerland but also Vietnam and thus presents the largest barrier to meat reduction. The association between response cost of eating less meat and intention to reduce meat was negative in Switzerland but positive in Vietnam. Self-efficacy of meat consumption reduction influenced meat consumption level solely in Switzerland. Ethical and environmental attitudes significantly facilitated meat reduction intention of Swiss respondents only, reflecting cultural differences. Policy implications were discussed.

What factors influence sustainable and healthy diet consumption? A review and synthesis of literature within the university setting and beyond

Globally, typical dietary patterns are neither healthy nor sustainable. Recognizing the key role of dietary change in reducing noncommunicable disease risk and addressing environmental degradation, it is crucial to understand how to shift individuals toward a sustainable and healthy diet (SHD). In this literature review, we introduced the concept of a SHD and outlined the dietary behaviors necessary to transition toward SHD consumption; we reviewed the literature on factors that may influence sustainable (and unsustainable) dietary behaviors in adults; and we developed a novel scoring system to rank factors by priority for targeting in future research. Given the significant potential to promote a sustainable and healthy dietary transition on the university campus-where factors that may impact dietary behaviors can be targeted at all levels of influence (i.e., individual, interpersonal, environmental, policy)-we narrowed our focus to this setting throughout. Aided by our novel scoring system, we identified conscious habitual eating, product price, food availability/accessibility, product convenience, self-regulation skills, knowledge of animal ethics/welfare, food promotion, and eating norms as important modifiable factors that may influence university students' dietary behaviors. When scored without consideration for the university population, these factors were also ranked as highest priority, as was modified portion sizes. Our findings offer insight into factors that may warrant attention in future research aimed at promoting SHDs. In particular, the high-priority factors identified from our synthesis of the literature could help guide the development of more personalized dietary behavioral interventions within the university setting and beyond.

Stages of Change toward Meat Reduction: Associations with Motives and Longitudinal Dietary Data on Animal-Based and Plant-Based Food Intakes in French Adults

BACKGROUND

Reducing meat consumption is advocated for healthier and more sustainable diets. However, behavioral studies are needed to better understand the mechanisms underlying meat-reducing dietary changes.

OBJECTIVES

The main aim of this study was to compare the motives associated with stages of change toward meat reduction in French adults, using the transtheoretical model (TTM). A second aim was to investigate the associations between stages of change and adherence to dietary patterns favoring a better balance of animal and plant food consumption over time.

METHODS

This longitudinal study included 25,143 non-vegetarian participants of the web-based NutriNet-Santé cohort with a mean follow-up of 6.2 (SD = 2.6) y. Dietary data were obtained from 24-h dietary records over the period 2009-2019. The contribution of meat to total energy intake and scores measuring the contribution of healthy and unhealthy plant-based foods to the diet were computed. A questionnaire completed in 2018 allowed us to identify the TTM stages of change related to meat reduction (precontemplation, contemplation, preparation, action, and maintenance), and recorded motives related to meat consumption. We used multivariate linear mixed models for repeated data to assess associations between food intake changes and stages, and logistic regression for motives, presented as adjusted frequencies.

RESULTS

Participants in later stages were characterized by a significantly higher decrease in meat intake over time, compared with the earliest stage (for example, βmaintenance ∗ time = -0.08, P < 0.0001), and a higher increase in the healthy plant-based food consumption score over time (for example, βmaintenance∗time = 0.11, P < 0.0001). Concerns about health, nutrition, and the environment were the most frequently cited motives for reducing meat consumption at all stages.

CONCLUSIONS

Individuals who had already initiated meat reduction adhered to healthier and more sustainable diets than meat continuers. Characterizing motives according to readiness to reduce meat consumption could support tailored public health campaigns.

Meat Consumption and Availability for Its Reduction by Health and Environmental Concerns: A Pilot Study

(1) Background: Excessive meat consumption has raised multiple health and environmental concerns; however, there are no data on the population's willingness to reduce its intake for these reasons. The current study aims to assess the frequency of meat intake and readiness to limit consumption due to concern about the impact on health and the environment in residents of the Lisbon metropolitan region. (2) Methods: This analytical cross-sectional observational study was carried out in 197 residents in the metropolitan region of Lisbon. The participants were divided into two groups by age (GI: 20-29 years; GII: 40-64 years). Meat consumption and willingness to reduce it were assessed through a questionnaire. (3) Results: Most participants (67%) reported not having knowledge about the ecological footprint of meat. Being a less frequent meat consumer (<1 time per day) is associated with a willingness 3.6 times higher (p < 0.001) to reduce meat consumption due to sensitivity to the impact on health and 4.0 times higher (p < 0.001) due to environmental reasons. (4) Conclusions: Lower meat consumption frequency was associated with reductions in this consumption for environmental and health reasons.

Loss framing effect on reducing excessive red and processed meat consumption: Evidence from Italy

A reduction of meat consumption is crucial for addressing public health problems, especially in industrialized countries. Among low-cost interventions, emotionally provocative health-information strategies could be effective options in fostering meat reduction. Through an online experimental survey, administrated to a quota-based national sample (N = 1142), this study analysed the profile of Italians consuming red/processed meat above World Health Organization (WHO) recommended amounts. Via a between-subjects design, the research tested whether two health frame-nudges (societal impact and individual impact of over consumption) persuaded these individuals to reduce future meat consumption. Results showed that adhering to an omnivore diet, higher consumption of meat than peers, household size (larger) and positive moral perception of meat consumption increased the likelihood of overconsumption. In addition, both nudges proved to be effective in positively impacting future intentions to reduce meat consumption among individuals exceeding WHO recommended amounts. The two frame-nudges were more effective among females, respondents with children in the household and individuals with a low health status perception.

The purchase willingness of consumers for red meat in China

The aim of this study was to explore the purchase willingness of Chinese consumers for pork, beef, lamb, and rabbit meat. A conceptual framework and focus group discussions were adopted to design the questionnaire which included experience, eating habits, purchase drivers, purchase location, seasonality, and willingness to purchase red meat among Chinese consumers. Data collection was undertaken using an online platform questionnaire, with 4039 meat consumers participating in this study. By constructing the partial least squares - path modeling (PLS-PM) to explore the concerns of Chinese consumers while purchasing various types of red meats as well as the effect of these questions on consumers' willingness intensity to purchase red meat. Willingness intensity to purchase lamb is significantly affected by experience, seasonality, purchase location, eating habits, willingness, purchase drivers, and personal information; beef is affected by experience, seasonality, purchase location, eating habits, willingness, and personal information; pork is mainly affected by eating habits and purchase drivers; while eating habits, purchase location, and personal information have positive impacts on willingness intensity to purchase rabbit meat. This study developed the orthogonal matching pursuit - stochastic gradient descent (OMP-SDG) model, which integrated the questionnaire collecting personal information with the questionnaire on Chinese consumers' perceptions of red meat. The program can more precisely forecast which types of red meat people like and their degree of willingness. Finally, Chinese consumers preferred beef, lamb, pork, and rabbit meat in that order. They also prefer local meat, believing it to be of high quality and providing a satisfactory sensory experience, appearance, and saturation.

Beef Consumers Behaviour and Preferences—The Case of Portugal

Meat consumption is estimated to increase worldwide, mostly because of the increase in population. Further, this increase in meat consumption will ultimately affect the environment and aggravate climate change. Herein, consumers’ behaviour was studied to understand if consumers would consider a change in their dietary habits by choosing beef from the Portuguese autochthonous bovine breed or even reducing their meat intake for environmental reasons. In 2021, a survey was conducted online and in some food sales outlets in Portugal. Therefore, data collected from the 491 participants were analysed with the aim of assessing the Portuguese consumer behaviour and preferences on beef. Firstly, we conducted a descriptive analysis. Then, factor analysis was performed by principal component analysis. Finally, by cluster analysis, we attempted to identify a group of consumers with different behaviours into specific categories. Although it was not possible to segregate consumers into different categories, most of the respondents agree that meat consumption harms the environment; however, just 30.6% are willing to reduce meat consumption due to environmental reasons. As for the concerns for animal welfare, respondents between the age of 23 and 49 years seem to have a greater concern towards animal welfare. To value autochthonous bovine Jarmelista meat, it is fundamental to implement a concerted communication between suppliers and producers to value Jarmelista beef. Furthermore, it is also important that regional governmental institutions support local producers not only for financial support but also to create strategies to protect the breed from extinction.

Exploring the Future of Edible Insects in Europe

The effects of population increase and food production on the environment have prompted various international organizations to focus on the future potential for more environmentally friendly and alternative protein products. One of those alternatives might be edible insects. Entomophagy, the practice of eating insects by humans, is common in some places but has traditionally been shunned in others, such as European countries. The last decade has seen a growing interest from the public and private sectors to the research in the sphere of edible insects, as well as significant steps forward from the legislative perspective. In the EU, edible insects are considered novel foods, therefore a specific request and procedure must be followed to place them in the market; in fact, until now, four requests regarding insects as a novel food have been approved. Insects could also be used as feed for livestock, helping to increase food production without burdening the environment (indirect entomophagy). Market perspectives for the middle of this decade indicate that most of the demand will be from the feed sector (as pet food or livestock feed production). Undoubtedly, this sector is gaining momentum and its potential relies not only in food, but also in feed in the context of a circular economy.
