Cultured or “clean” meat (CM) is arguably a more ethical and environmentally sustainable alternative to farmed meat, but several potential psychological barriers exist to its acceptance in the marketplace. The perceptions of youth, as a specific consumer cohort, have not been reported to date despite young adults having more flexible dietary habits and being more likely to avoid red meat because of animal welfare and environmental concerns. Thus, youth represent a demographic that may be more accepting of CM and for whom the pro-environmental consequences of early adoption may be realized across an entire lifespan. In this study of college-aged Canadians (mean = 20 years), we examined perceptions of CM (mixed methods) and assessed the effects of educational messaging about its benefits and then naturalness framing on intention to consume it (within subjects quantitative experimental design). Results show that youth believe CM to be unnatural, ethical, and environmentally friendly, and that taste is an important element of acceptance. Linear regression showed that food disgust was a significant predictor for both intent to incorporate CM into regular diet and completely replace meat/meat substitutes with CM. In both instances, increasing food disgust was associated with lower behavioral intent. Environmental values were also a predictor for completely replacing meat/meat substitutes with CM, where it positively affected intent and showed a similar effect size to food disgust. Both messaging on the benefits of CM and naturalness framing increased intent to consume it across all three measures and by a similar magnitude [p (F) < 0.05]. These findings provide timely and actionable information for both CM producers and marketers and contribute to scholarship on the role of values and psychological traits in sustainable food choices.
Cultured meat (CM) is poised to disrupt the meat industry, holding much promise as a sustainable and alternative protein to that sourced from the traditional intensive animal agriculture system (Tuomisto and Teixeira de Mattos, 2011). However, for this potential to be realized, a comprehensive understanding of how it is perceived by consumers and what the barriers are to its acceptance is needed (Siegrist et al., 2018). Youth are a key demographic to consider in this context, as their habitual dietary behavior is more flexible (Whitelock and Ensaff, 2018) and the environmental impact of their food choices can be realized over a longer time span compared with older individuals. To date there has been limited consideration regarding young adults' perceptions of and barriers to adopting CM, and how these factors can be incorporated into effective messaging strategies. These knowledge gaps inform the current study.
A preponderance of literature indicates that climate change represents an existential threat to human civilization and that sweeping and immediate changes must be made across sectors in order to prevent the most devastating effects of climate change; “business as usual” is no longer a tenable option (Masson-Delmotte et al., 2018). Approximately 18% of global greenhouse gas (GHG) emissions can be attributed to animal agriculture (Steinfeld et al., 2006), making it one of the greatest contributors to climate change (Steinfeld et al., 2006). Aside from significant GHG emissions, livestock production is also responsible for large amounts of deforestation primarily to create crop fields for livestock feed, significant water use and water quality degradation, and strain on the global nitrogen cycle (Steinfeld et al., 2006; Roos et al., 2013; Westhoek et al., 2014). In the case of the global nitrogen cycle, evidence suggests that a planetary boundary has already been exceeded (Stevens, 2019). The negative environmental impacts of animal agriculture may worsen over the next several years, as the rate of meat consumption in developing countries continues to grow rapidly (Delgado, 2003; FAO, 2006; Allievi et al., 2015). At the level of the consumer, awareness of these environmental impacts of meat production and consumption appears surprisingly low (Stea and Pickering, 2018), and even when consumers are aware, most seem unwilling to remove meat from their diets (Hartmann and Siegrist, 2017).
The market for meat substitutes in western nations is increasing and is projected to continue to grow globally over coming years (Fortune Business Insights, 2019). In addition to an increase in the number of individuals adopting vegan and vegetarian lifestyles in western countries, meat substitutes are also finding increasing favor among meat eaters who want to engage in more ethical, environmentally friendly, and healthy food choices (Bourassa, 2019). However, even greater uptake of plant-based alternatives, particularly amongst non-, light- and medium-users, is limited mainly by negative beliefs about their sensory appeal (Hoek et al., 2011). These challenges, coupled with the need for environmentally sustainable food systems, provide opportunities for alternative approaches to traditional intensive animal agriculture.
CM offers a potential alternative protein source both for individuals who avoid meat because of ethical, religious, or environmental concerns associated with industrialized production methods, and for current meat-eaters who desire a more environmentally sustainable source or reject meat substitutes due to taste concerns. It is a product of cellular agriculture produced using tissue-engineering technology where the muscle cells of animals are cultured in a bio-reactor independent from the animal (Bhat et al., 2017). By comparison, fermentation-based cellular agriculture does not use any tissue from a living animal; instead, edible products are engineered by fermentation using bacteria, algae or yeast that have typically been genetically modified through the addition of recombinant DNA (Stephens et al., 2018). The culture media that is used in producing CM includes fetal animal serum, which contains a range of growth factors, hormones, vitamins, and other components necessary to support cell growth. Antibiotics are also sometimes added to the cells in culture to prevent infection (Stephens et al., 2018). A scaffold is then used to facilitate cell adhesion, proliferation, and tissue development in order to form a 3D skeletal muscle. A review of the technological considerations around CM manufacture—including the wider benefits and objections–can be found in Bhat et al. (2017).
In addition to the potential ethical benefits of a slaughter free harvest, most literature concludes that CM is significantly better for the environment on multiple fronts. For instance, Tuomisto and Teixeira de Mattos (2011) compared 1,000 kg of beef, sheep, pork, and poultry to 1,000 kg of CM, and calculated CM production uses 7–45% less energy, 99% less land, 82–96% less water, and emits 78–96% less GHG. While most existent literature agrees that CM is environmentally much more sustainable, Lynch and Pierrehumbert (2019) have recently challenged the assumption that CM is climatically better than cattle, arguing that its relative GHG emissions depend on the specific production system used and the availability of decarbonized energy generation. There are also several other potential drawbacks to CM as a whole. The animal-derived serums currently required in the cell growth phase of production are expensive, and their animal origins may be a barrier for some consumers (Stephens et al., 2018). The health impacts of cultured red meat must also be considered, given that consumption of red meat is linked to coronary heart disease, cancer, and mortality risk (Ferguson, 2010; Zhong et al., 2020). However, CM also offers the potential during production to engineer changes at the cellular and tissue levels, which may extend in the future to reducing or altering molecules associated with these health impacts (Post, 2012). Regardless, some consumers appear less accepting of the risks linked with meat consumption, including colon cancer, when the source is considered unnatural (e.g., cultured) as opposed to traditionally farmed (Siegrist and Sütterlin, 2017). Despite these challenges, recent years have seen considerable interest and investment in start-up enterprises seeking to both scale-up CM to commercial production levels and bring down associated costs. In recognition that CM will likely be “on the shelves” sooner rather than later, the United States Department of Agriculture and Food and Drug Administration approved CM in late 2018, and announced that they would jointly oversee its production in order to assure it could be safely sold to consumers across the USA (Commissioner, 2018), reflecting similar regulatory activity in other countries. CM appears well on its way to becoming a commercially available alternative to farmed meat.
Despite the environmental and animal welfare benefits of CM, several potential barriers to consumer acceptance have been identified. Two of these are often associated with acceptance of new foods more generally; food disgust and food neophobia (Hoek et al., 2011; Siegrist et al., 2018). Disgust is a natural biological response that can lead to avoidance of some foods, while food neophobia is a personal trait that describes one's willingness to try new food. Egolf et al. (2018) reported that Swiss adults with higher levels of food disgust tend to be pickier eaters and are less likely to try new foods. Also in a Swiss population, Siegrist et al. (2018) found that descriptions of CM evoked high levels of reported disgust from participants and negatively impacted their perceptions of it. Similarly, a recent study with US participants by Wilks et al. (2019) found that food disgust and food neophobia were very strong predictors of absolute opposition to CM. In addition, food neophobia is a significant predictor of willingness to try new foods generally (Tuorila et al., 2001) and food neophobes tend to make more negative evaluations and have different expectations toward unfamiliar foods (Raudenbush and Frank, 1999). However, food neophobia does not seem to be associated with consumers' willingness to try products created through new food technologies, such as those involving genetically modified organisms (Siegrist, 2008).
The greatest psychological barrier to consumption of CM may be its perceived unnaturalness, with several studies across multiple countries citing this as a significant concern for potential consumers (Laestadius and Caldwell, 2015; Verbeke et al., 2015a; Siegrist et al., 2018). When defining what makes food natural, consumers often state that the production process should involve minimal processing and follow traditional production methods (Román et al., 2017). CM is produced using tissue engineering technology which appears to be perceived as inherently unnatural, and when consumers view a food technology as unnatural they are more likely to believe that technology is risky and are less accepting of its possible benefits (Ronteltap et al., 2016).
While consumers perceive CM to be unnatural which may impact their intent to eat it, it is less clear to what extent this belief is susceptible to change through consumer education on the benefits of CM or through how the product is framed in promotion and messaging activities. These considerations have been given some preliminary attention in both peer reviewed (Verbeke et al., 2015b; Siegrist and Sütterlin, 2017) and non-peer reviewed (Anderson and Bryant, 2018) media in recent years. Both intent to reduce intake of farmed red meat in Canada (Stea and Pickering, 2018) and willingness to consume CM in Belgium (Verbeke et al., 2015b) increase when information alone is provided on the environmental issues associated with traditional meat production. Message framing also offers the potential to elicit greater pro-environmental behavior across a range of activities, including food consumption (Smith and Petty, 1996; Gifford and Bernard, 2006; Goldstein et al., 2008). There are many ways in which framing can be conceptualized and operationalized. For instance, equivalency framing uses different but logically equivalent words or phrases to alter thinking or preferences (e.g., 95% fat-free or 5% fat), whereas emphasis framing—used in the current study–stresses a subset of relevant considerations (Druckman, 2001). Siegrist and Sütterlin (2017) have noted that Swiss and European Union consumers rely heavily on symbolic information when evaluating foods, particularly information that positions them as more natural, such as “organic” and “non-GMO” (examples of emphasis framing). Given these considerations, we expect that behavioral intent toward CM may be enhanced through both consumer education on its benefits and messaging that is framed around naturalness.
The main objectives of the present research are to:
1. Determine the opinions and beliefs held by youth toward CM.
2. Determine the relationship between willingness to consume CM and food neophobia, food disgust (H2), and environmental values (as assessed by the shortened version Whitmarsh, 2011 of the New Ecological Paradigm Dunlap and Van Liere, 1978).
3. Determine the impact on behavioral intent of educational messaging around the general benefits of CM and framing it as natural; specifically, willingness to try CM, willingness to incorporate CM into regular diet, and willingness to completely replace farmed meat/meat alternatives with CM in regular diet.
Our hypotheses are:
1. Food neophobia will be negatively associated with willingness to consume CM (H1).
2. Food disgust will be negatively associated with willingness to consume CM (H2).
3. Given that adults with high environmental values show greater preference for CM than those with lower values (Slade, 2018), we expect that the same relationship will hold for youth (H3).
4. Youth will show greater willingness to eat CM in response to both educational information and naturalness framing (H4).
Youth has been chosen as the demographic for this study for several reasons. There is a lack of prior research on CM and youth specifically, and young adults have more flexible dietary habits than older individuals and are more likely to eat meatless meals and avoid red meat due to animal welfare and environmental concerns (Ruby, 2012; Whitelock and Ensaff, 2018). Food choice can be a means of enacting one's identity and communicating it to others, and the transition into adulthood provides an opportunity for young adults to explore different identities as eaters (Devine, 2005), including the adoption of diets and products that were not part of their upbringing. Taken together, these considerations suggest that they are a demographic that could be more accepting of CM. From an industry perspective, youth may be a more profitable market segment if CM is incorporated into habitual diet across the lifespan, in addition to the long-term potential environmental impact. Our study builds on existent literature by focusing on the perception and attitudes of young adults and examines for the first time the role of food disgust and food neophobia in moderating these percepts in youth. Additionally, it employs experimental manipulation of educational information and naturalness messaging to capture quantitatively behavioral intent toward CM. Our findings will inform considerations around the marketing and viability of CM and contribute to the development of a more sustainable food system.
Materials and Methods
Recruitment and Sample Description
A convenience sample of 214 Canadians college-aged participants was recruited between October-December, 2018, through Brock University's SONA (research trial recruitment) system, posters, and social media posts. Brock University has a student population of 19,100. The title of the project communicated to prospective participants was “Perceptions of cultured meat and optimization of messaging,” with the following study description provided: “The purpose of this study is to understand the attitudes of college-aged students hold toward cultured meat.” Eligibility criteria required that participants be 18–30 years of age and Canadian citizens or permanent residents. Respondents from Brock were offered research credit as an incentive that could be used toward course credit in one of several classes. The median time of completion for the online survey (32 questions) was 9.9 min, and 14 participants were removed due to incomplete data leaving 200 useable responses. Participants used an URL link to access the survey which was administered using the Qualtrics™ platform (2015, Provo, Utah, US). Ethics clearance was granted by the Brock University Research Ethics Board (File #18-036). All participants gave written informed consent in accordance with the Declaration of Helsinki.
Demographics, Meat Consumption, and Environmental Values
Demographic information was collected using measures adapted form Morris and Pickering (2019), including citizenship, age, ethnicity, gender, political orientation, and importance of religion. Participants were then asked to indicate on average how many times a month they consumed meat, using response categories which ranged from 0 to 80+. If participants indicated that they ate meat zero times a month they were then prompted to indicate what they most closely identified as (pescetarian, vegetarian, vegan—categories adapted from Mayo Clinic, 2019) followed by a check-all-that-apply scale where they provided their reasoning for not consuming meat (ethical concerns, health reasons, environmental concerns, allergies, do not enjoy the taste, social pressures; adapted from Rozin et al., 1997). Other participants were asked to select all of the types of meat that they regularly consumed on a check-all-that-apply scale (beef, pork, poultry, fish/other seafood, deer/rabbit, other). Participants then completed a shortened version (Whitmarsh, 2011) of the New Ecological Paradigm (NEP; Dunlap and Van Liere, 1978) which measures environmental values, with responses to indicator statements captured on 5-point Likert scales (Supplementary Materials).
Attitudes and Behavioral Barriers
Using a mixed-methods approach, participants' opinions of CM were examined. First, current knowledge about CM was assessed by asking participants how much they know about the product, with response options on a five-point Likert scale ranging from nothing at all to a great deal. Participants were then given the following passage briefly describing CM, adapted from Siegrist et al. (2018): Cultured meat (“lab-grown meat”) is produced using tissue-engineering technology where animals cells are grown in a controlled environment outside of and independently of the animal, which results in no animals being harmed or killed in the process. The end product is comparable to traditional meat with regard to texture and taste. Our adaptation was mainly to adjust the wording away from the ground beef focus of Siegrist et al. (2018) to make the passage more generalizable to all CM.
After this passage participants were asked an open-ended question about their opinion on consuming CM. Content analysis was then applied to these responses using NVivo12 and following the general approach of Morris and Pickering (2019). Individual responses were read by both authors, and tentative themes determined. During an iterative process these theme categories were further refined. A codebook was then developed that articulated the criteria for binning each response into a thematic category (refer Supplementary Materials). Individual opinions that reflected multiple concepts (e.g., both Animal welfare and Health) were counted in each of the relevant theme categories. Counts for each category were then made and expressed as a percentage of total responses. Respondents were then asked five questions, based on common opinions and proposed benefits identified in other studies and populations (Verbeke et al., 2015a; Bhat et al., 2017), which they responded to on a 5-point Likert scale: How healthy do you think cultured meat is? How natural do you think cultured meat is? How environmentally friendly do you think cultured meat is? How ethical do you think cultured meat is? How disgusting do you think cultured meat is? Next, participants rated how strongly they agreed with four statements on potential barriers adapted from Verbeke et al. (2015b) (5-point Likert scale, ranging from strongly agree to strongly disagree): Cultured meat wouldn't taste the same as farmed meat; I would not be willing to spend more money on cultured meat; science does not understand enough about cultured meat to sell it as a viable alternative; I do not see any personal benefits to eating cultured meat.
At the end of the survey, after the messaging treatments below, we administered the shortened Food Disgust Scale (Hartmann and Siegrist, 2018), as validated in English by Egolf et al. (2019) and Thibodeau et al. (in press) and the Food Neophobia Scale (Pliner and Hobden, 1992; 5-point Likert scale–strongly agree to strongly disagree) to further investigate potential psychological barriers to CM consumption (Supplementary Materials).
Participants initially answered three questions about their intention to consume CM on a 7-point Likert scale, ranging from extremely unlikely to extremely likely: (1) If readily available, how likely is it that you would try cultured meat?; (2) If readily available, how likely is it that you would incorporate cultured meat into your regular diet? The final question differed depending on participants' previously indicated meat consumption habits. Those who indicated they ate meat zero times a month answered (3) If readily available, how likely is it that you would completely replace meat alternatives with cultured meat in your regular diet? Whereas, those who ate meat one or more times a month answered (4) If readily available, how likely is it that you would completely replace farmed meat with cultured meat in your regular diet?
Participants were then shown five statements which outlined the general potential benefits of CM (“educational information”) adapted from Bhat et al. (2017) and Stephens et al. (2018): Cultured meat is produced using tissue-engineering technology and does not involve the traditional methods of rearing and slaughtering animals; Cultured meat could greatly reduce the number of food-borne illnesses such as salmonella; There is no animal suffering involved in the production of cultured meat; Cultured meat is produced in a lab and therefore does not require nearly as much land as traditional animal agriculture; Cultured meat could be used to combat starvation and malnutrition in third world countries. After reading these five statements, participants again indicated their intention to consume CM by responding to the three questions detailed above on 7-point Likert scales.
Participants were then shown five statements that framed CM as natural, adapted from Figure 2 of the systematic review on food naturalness perception of Román et al. (2017): Cultured meat can be enhanced to contain healthy vitamins and reduce the amount of unhealthy fats; Cultured meat contains no artificial colors/flavors, preservatives, or additives; No chemicals, hormones, or pesticides are used in the production of cultured meat; Cultured meat is free of all GMOs (genetically modified organisms); Cultured meat could reduce the carbon footprint of the animal agriculture industry and reduce its greenhouse gas emissions by up to 90%. After reading these five statements, participants again indicated their intention to consume CM by responding to the three questions detailed above on 7-point Likert scales.
This empirical research design involves experimental manipulation whereby the independent variable(s) (the type of information/messaging the participants receive) are systematically varied to examine the effect on the dependent variable(s) (intent to consume CM) (Ruble, 2017). It is an approach that is common in several academic disciplines, including communications and psychology, and has been used to examine how information or its framing influence pro-environmental behaviors and beliefs in recent studies (e.g., Stea and Pickering, 2018; Munoz-Carrier et al., 2020). While we acknowledge that the accuracy of some of the statements included in the “educational information” and “naturalness framing” treatments may be debatable, we believe they have good ecologically validity with respect to how the CM industry is positioning and some media is reporting on these products (Goodwin and Shoulders, 2013), and they are informed by existent peer-reviewed literature (for reviews, see Bhat et al., 2017 and Bryant and Barnett, 2018).
The survey was field-tested with 10 college-aged volunteers to assess question comprehension and clarity, and survey flow and logistics. No substantive issues were identified, and two (minor) operational changes were made to the final survey before launching.
The average age of our 200 respondents was 20.4 years, with 79.5% identifying as female, 20% male, and 0.5% as other. With respect to political identification, 13% identified as conservative, 40% identified as neutral, and 48% identified as liberal. For meat consumption, 12% indicated that they consumed meat zero times a month, 68% indicated that they consumed meat 1–30 times a month, and 21% indicated that they consumed meat 31 or more times a month. In response to the question “How much do you know about cultured meat?,” 1% indicated they knew a great deal, 2% indicated they knew a lot, 16% indicated they knew a moderate amount, 36% indicated they knew a little, and 46% indicated they knew nothing at all.
Opinions and Barriers
Participants were asked an open response question about their opinion of the consumption of CM. The most common themes to emerge were the possible benefits CM could have for animal welfare and the environment, and concerns about the naturalness of the product (Table 1). Of the 71% of responses that could be clearly identified as either generally positive or generally negative, 69% were positive while only 31% were negative.
Table 1. Key themes from the open response question “What is your opinion about the consumption of cultured meat?”
Participants were then asked how healthy, natural, environmentally friendly, ethical, and disgusting they thought CM was (Figure 1). The majority indicated that they found CM to be somewhat or very unnatural (67%), somewhat or very ethical 64%, and somewhat or very environmentally friendly (61%). There was no majority agreement on how disgusting CM was regarded, with 36% finding it not disgusting at all or not very disgusting, 33% rating it somewhat or very disgusting and 32% having no opinion. The distribution was also very similar for opinions on healthiness.
Figure 1. Attitudes regarding naturalness, ethics, environmental friendliness, disgust, and healthiness of cultured meat (frequency response).
With respect to response to statements that capture consumer objections identified by Verbeke et al. (2015b) (Figure 2), “I do not see any personal benefits to eating CM” elicited the most disagreement with 59% indicating they moderately or strongly disagreed. Responses to “I would not be willing to spend more money on CM” were the most polarized with 45% stating they moderately or strongly agreed and 40% stating that they moderately or strongly disagreed.
Figure 2. Potential barriers to consumption of cultured meat. Data show level of agreement with four statements adapted from Verbeke et al. (2015b) (% of responses).
The statement “Science does not understand enough about CM to sell it as a viable alternative” had the largest proportion of respondents indicating they neither agreed nor disagreed (36%), with the remaining responses split relatively evenly between moderate or strong agreement (34%) and moderate or strong disagreement (31%). Responses to “CM wouldn't taste the same as farmed meat” were relatively evenly distributed between moderate or strong agreement (38%), moderate or strong disagreement (30%), and neither agreement nor disagreement (32%).
Behavioral Intent and Response to Messaging
Prior to message exposure participants were asked to indicate their intention to try CM, incorporate CM into their regular diets, and replace farmed meat/meat alternatives with CM in their regular diets. We ran a linear regression for each intention to examine the influence of food disgust, food neophobia, and environmental values (NEP score). Age, gender, and political orientation were included in the initial regressions, but as they did not affect the results for the main effects that we were investigating (food disgust, food neophobia, environmental values), they were not included in the final models (data not shown). As shown in Table 2, food disgust was a significant predictor for both intent to incorporate CM into regular diet and completely replace meat/meat substitutes with CM. In both instances, increasing food disgust associated with lower behavioral intent. Increasing NEP score also predicted intent to completely replace meat/meat substitutes with CM, and showed a similar effect size to food disgust. There was no association found between participants' food disgust scores and how disgusting they rated CM (r = 0.08, p = 0.24). The distributions of the food neophobia, NEP and food disgust scores are given in Supplementary Materials.
Table 2. Predictors (linear regression) of initial intent to try culture meat, incorporate it into regular diet, and completely replace meat/meat substitutes with it.
Behavioral intent was assessed again after exposure to each of the messages; the first message highlighted the general benefits of CM and the second framed CM as natural (Figure 3).
Figure 3. Intention to try cultured meat, incorporate cultured meat into regular diet, and replace farmed meat/meat alternatives with cultured meat in regular diet across messaging treatments. Data shown are average responses from 7-point Likert scale (1 = “extremely unlikely” 7 = “extremely likely”) ± standard error. A, B, and C represent significant differences between the messaging treatments (Bonferroni 0.05).
Additionally, participants were asked How natural do you think cultured meat is? both before and after messaging as a validity check of the naturalness frame. Overall, participants indicated they found CM to be more natural after message exposure [t(198) = 5.03, p < 0.001], suggesting the intended naturalness construct was elicited by the messaging.
Three one-way within subjects ANOVAs were conducted to examine changes in intent to try, incorporate, or replace with cultured meat across the three messaging treatments (no messaging, educational messaging, educational plus naturalness messaging), followed by Bonferroni post-hoc tests. Greenhouse-Geisser corrections were also applied to all three ANOVAs to adjust for violation of sphericity. F-values were significant for all of the dependent variables; try [F(1.76, 199) = 16.57, p < 0.001], incorporate [F(1.65, 199) = 42.25, p < 0.001], and replace [F(1.71, 199) = 49.85, p < 0.001], with Bonferroni results showing that each sequential message elicited greater behavioral intent for each of the dependent variables. Specifically, when participants were given information about the general benefits of CM there was a 5% increase in intent to try CM, a 16% increase in intent to incorporate CM into their regular diets, and an 18% increase in intent to replace farmed meat/meat alternatives with CM. When CM was then framed as natural participants reported an additional 6% increase in intent to try CM, a 12% increase in intent to incorporate CM into their regular diets, and a 15% increase in intent to replace farmed meat/meat alternatives with CM.
Moderating Factors and Examination of Group Differences
A multiple regression was run to test the effect of environmental values (New Ecological Paradigm), food neophobia (Food Neophobia Scale), and food disgust (Food Disgust Scale) on change in intention to consume CM after messaging. Change in intent was quantified by subtracting each participant's score after the naturalness messaging from their score before any messaging. Three regressions were run with change in intention to try CM, change in intention to incorporate CM into regular diet, and change in intention to completely replace farmed meat/meat alternatives with CM as the dependent variables. There were no significant effects, for try [F(4, 197) = 0.56, p = 0.69], incorporate [F(4, 197) = 2.16, p = 0.08], or replace [F(4, 197) = 0.60, p = 0.66], suggesting that environmental values, level of food disgust, and level of food neophobia did not influence response to messaging.
We also examined whether there were any group differences between participants who responded positively to the messaging (showed increase in intent) and those who did not (no change in intent) for willingness to try, incorporate, and replace. The groups that were compared were males (n = 40) vs. females (n = 159), vegetarians/vegans (n = 23) vs. meat eaters (n = 177), low meat consumers (0–30 times a month; n = 159) vs. high meat consumers (31+ times a month; n = 41), low environmental values (NEP score of 3.99 or less; n = 80) vs. high environmental values (NEP score of 4.00 or more; n = 120), those who stated religion was an important aspect of their lives (n = 115) vs. those who stated that it was not (n = 85), and liberals (n = 96) vs. conservatives (n = 25). Chi-squared tests did not reveal differences between any of these groups for any of the three intent measures [p(χ2) < 0.05]. In some instances, the analyses may have been underpowered due to small group sizes (refer Supplementary Materials).
Perceptions, Behavioral Intent and Implications
This study is the first known to us that reports on young adults' opinions of CM while also examining the effects of messaging on intention to consume it. Respondents see CM as promoting animal welfare, environmentally friendly, and unnatural, as evidenced from both open ended responses and targeted questions, consistent with previous reports on older cohorts (Laestadius and Caldwell, 2015; Verbeke et al., 2015a). Animal welfare was the most cited theme in the open-ended responses, and previous work with young adults has identified animal welfare concerns as a driver for eating less meat (reviewed in Ruby, 2012). Further research is encouraged to expand this finding and its potential for assisting in acceptance of CM. For instance, how appealing might CM be to ethical vegetarians (individuals who avoid meat due to moral consideration around animal welfare; Ruby, 2012), and to what extent might emphasis framing that stresses animal welfare benefits be an effective marketing strategy for some youth cohorts, including ethical vegetarians? Participants also indicated that an important factor when considering whether they would consume CM or not is whether it tastes the same as farmed meat, consistent with the report of van der Weele and Driessen (2019) in a Dutch cohort. This result provides some direction for CM producers with respect to optimizing their product and suggests that sensory and consumer testing should be critical components of the product development process in order to achieve market acceptance.
In contrast with Verbeke et al. (2015b), the majority of our participants disagreed with the statement “I do not see any personal benefits to eating CM.” It is not clear what personal benefits respondents may envision. They may be related to reduced environmental impact–one of the greatest suggested benefits of CM (Bhat et al., 2017)—and/or to reduced concern about animal welfare. Participants who had higher than average environmental values (NEP score > 4) were significantly more likely to disagree with the statement than those with a lower environmental values (NEP score ≤ 3.99) [X2 (1, N = 169) = 5.20, p < 0.05]. Thus, it is possible that individuals with higher environmental values may view the lower environmental impact of CM as a personal benefit.
There was no relationship between intention to consume CM and food neophobia; thus we failed to find evidence to support H1. Previous research has found that people who score higher for food neophobia are less willing to eat meat substitutes (Hoek et al., 2011) and food neophobia has been associated with rejection of CM in an adult sample (Wilks et al., 2019). However, our result is consistent with previous findings that food neophobia does not impact consumers' willingness to try foods that have been created through new technologies (Siegrist, 2008). Our null result may have been influenced by our initial description of CM as having a comparable taste and texture to farmed meat, as these are two of the most important qualities for meat consumers (Grunert et al., 2004) and two of the most common objections to consuming meat substitutes (Hoek et al., 2011).
We found a negative relationship between food disgust and initial intention to consume CM, confirming H2 (“Food disgust will be negatively associated with willingness to consume”) and consistent with the report of Siegrist et al. (2018) that descriptions of CM evoke high levels of reported disgust and negatively impact perceptions of it. However, we did not find a relationship between food disgust and intention to consume CM after messaging, indicating that food disgust may not be a barrier to consumer acceptance of CM if effective messaging strategies can be employed. There was no relationship found between NEP scores and intention to consume CM; thus we failed to find evidence to support H3, contrary to previous findings that individuals with high environmental values have a stronger preference for CM (Slade, 2018). However, our sample had very high pro-environmental values, consistent with the wider Canadian population (Pickering, 2015), with an average NEP score of 4.0 ± 0.6 SD. There may have been insufficient variation in responses to capture a relationship. Slade (2018) also found that men and liberals were more receptive to CM than woman and conservatives; however, we did not replicate these findings in our data. This may be attributable to our analyses being underpowered, as only 40 respondents were men and only 25 identified as conservative.
Message Frame Effectiveness and Implications
Educational messaging (Pickering et al., 2020) and message framing (Smith and Petty, 1996) can be effective tools in eliciting desired behavior, and consumers have shown increase in intent to consume products such as organic foods or CM when they are provided with information about their benefits or when they are framed positively (Gifford and Bernard, 2006; Siegrist and Sütterlin, 2017). Message framing has also been show to assist people in adopting pro-environmental behaviors more broadly (e.g., Goldstein et al., 2008; Stea and Pickering, 2018) and in overcoming cognitive and behavioral biases (Asensio and Delmas, 2016). In our study, both providing participants with information on the general benefits of CM and then framing it as natural increased intent to consume CM, confirming H4 (“Youth will show greater willingness to eat CM in response to both educational information and naturalness framing”). The effect of educational messaging stressing the benefits is perhaps not surprising, given that a significant minority of this cohort were unfamiliar with the product prior to the study commencing. The positive influence of naturalness framing is consistent with our finding that the majority of respondents considered CM to be unnatural prior to messaging, and agrees with predictions that could reasonably be drawn from earlier reports showing that perceived unnaturalness is a significant concern for adult consumers (Laestadius and Caldwell, 2015; Verbeke et al., 2015a; Siegrist et al., 2018). It is possible that alternative or complimentary framing approaches to naturalness could elicit even greater behavioral intent by youth toward adopting CM, and future research is encouraged in this area. For instance, socially normative framing (Hurlstone et al., 2014) or highlighting the negative elements of farmed meat rather than the benefits of CM may be worth investigating.
This information may be useful for marketing CM, as it shows that both informing consumers about the benefits of CM and framing it as natural can alter intention to eat the product. Perhaps most importantly, both types of messaging led to a significant increase in intent to try CM. The “mere exposure effect” shows that the more someone tastes a product, the greater the likelihood that will like it and incorporate it into their diet (Pliner, 1982). Thus, for such a novel product as CM, marketing and promotional efforts that incorporate opportunities for customers to sample CM–such as free tasting stations in supermarkets–may be beneficial in helping to transition people through to becoming regular consumers. However, this speculation assumes that the sensory characteristics of CM can meet or exceed customer expectations; that is, they must be similar to farmed meat. Indeed, a potentially valuable avenue of future research would be to determine empirically just how similar CM products need to be to their farmed meat equivalents in order to achieve market acceptance.
While our results provide support for the use of specific messaging types to increase behavioral intent, there is the question of what the most effective way is to deliver these messages to young adults. The media used by youth to receive marketing is very different than for many older adults. The internet provides an array of new and constantly evolving platforms for food companies to reach consumers, with young people the primary users (Montgomery and Chester, 2009). Using social media as a marketing tool can be a very effective way to spread product information to a large audience. For instance, in 2019 there were one billion active Instagram users in the world, and in the United States over half were between the ages of 18 and 29 years old (Statista, 2018). Social media sites such as Instagram are one of the most effective ways to target youth, and likely will be a more successful option for delivering CM messaging to them than the more traditional print, radio and TV media.
Other Considerations and Limitations
Our study specifically examined young adults for several reasons. Firstly, youth inherit our changing climate and are key actors in promoting sustainable lifestyles, adopting environmentally-friendly practices and implementing adaption and mitigation projects (Youth Stats: Environment and Climate Change, 2015). They make up the majority of the population in several countries and their increasingly strong environmental awareness is a vital asset in climate change mitigation (Youth and Climate Change, 2010). Understanding their beliefs and motives around making more environmentally sustainable food choices is important if meaningful and lasting progress is to be made toward mitigating climate change (Pickering et al., in press). Additionally, young adults have more flexible dietary habits than older individuals (Whitelock and Ensaff, 2018), and those dietary habits that are established in childhood and adolescence tend to be stable into adulthood (Lake et al., 2006; Movassagh et al., 2017). Thus, marketing efforts that encourage youth to incorporate CM into their diets may help establish it as a component of habitual diet across their lifespans, and also represent an opportunity for “cradle-to-grave” branding for CM producers, which has proved successful for fast-food restaurant chains that use farmed meat.
A limitation of our study is that we measured participants' intention to consume CM and not their actual behavior. While intention is not a perfect indicator of behavior, the theory of planned behavior has shown that it is associated with action, including changing food intake (Ajzen, 1991). However, CM is not currently available commercially, and none of the participants have sampled it. This may result in CM being regarded as more “abstract” for participants and add additional uncertainty to the intention-behavior relationship. Another limitation is that we used a within subjects design whereby all participants received each of the messaging conditions, and we were not able to determine the specific effect of naturalness framing in the absence of the prior educational messaging on the benefits of CM. It would be of interest in further studies to assess to what extent perceptions of CM might vary with the type of cattle farming used for comparison (for instance, factory-farmed vs. grass-fed free-range). Finally, while our cohort was intended to be a convenience sample of college-aged Canadians, it may not be representative of the wider population of young adults with respect to sociodemographic and belief characteristics, and our sample size is limited. For instance, the influence of gender on attitudes toward CM and responses to messaging is of interest and could be explored with a larger and more representative sample in the future.
The Masson-Delmotte et al. (2018) has concluded we have <12 years to limit the effects of climate change and prevent catastrophic warming and associated impacts from occurring. Our current intensive animal agriculture system is not sustainable, and alternate production approaches are required (Tilman et al., 2002). Sustainable Development Goal 12 focuses on building sustainable consumption and production patterns across the globe (United Nations, 2015), and CM could make a significant contribution to this. This study contributes to our understanding of the psychological barriers to consumer acceptance of CM, with a focus on youth for the first time. Our results show that youth generally have positive attitudes toward CM and see personal benefit in consuming it. However, many are not willing to spend more money on the product compared to traditionally sourced meat and have concerns about its potential taste, informing pricing and production practices, respectively. Youth believe CM to be unnatural, but ethical and environmentally friendly. While food disgust is negatively associated with CM, it did not affect behavioral intent, suggesting that it is not a barrier to acceptance. Further, we show for the first time with youth that educational and naturalness messaging can be effective tools to increase intent to consume CM and incorporate it into diets; a finding that is robust across the value, attitude and psychological factors examined. Taken overall, our study provides actionable information for both CM producers and marketers and assists in the transition to a more sustainable food system.
