Master Thesis 2019 Master Thesis Consumer readiness towards plant-based consumption in selected Latin American Countries. MARÍA ALEJANDRA BRETTI ROBERT SUPERVISOR: Associate Professor F.J. Armando Perez-Cueto Eulert Associate Professor Christian Ritz SUBMITTED ON: 08 august 2019 ABSTRACT Introduction There is a proved association of mal nutrition in all its forms (obesity, undernutrition and other dietary risks) and climate change (Patterson et al., 2019). In the last report of the Lancet Commissions this concept is defined as “Syndemic” due to the synergy that these three main issues have to each other, and this is a global concern. One of the recommendations to fight this situation is move to a plant based diet (Boer, Schösler, & Boersema, 2013). The awareness in the develop countries is growing and some of them have included environmental sustainability in their dietary guidelines, however on Latin American countries, this evidence seems not to be enough to make real and consistent changes in laws and recommendations to fight this syndemic issue. This thesis was divided in two parts, first a systematic review with the aim of analyse the literature available published on Latin American countries regarding plant-based diet related to climate change and sustainable diet, and secondly a quantitative consumer survey distributed among selected Latin American countries to determine the readiness of the consumer to move towards a plant-based diet. Material and methods A quantitative consumer survey was carried out through online program surveyXact and distributed among selected Latin American countries, the questionnaire was developed in Spanish and the distribution was made with help of some collaborators in each country. The sampling methods was a non- probability snowball sampling. The inclusion criteria were defined by people from 15 to 99 years old, residents of the selected countries. The results from the survey were analysed using R and Rstudio® software, applying a fully adjustment model and descriptive statistics. i Results, discussion and conclusion The sample was composed by 827 respondents from three Latin American countries (BL N=245; BR N=260; CL N=322) with a mean age of 30.21 years old, most of the respondents were females and the majority of them have completed higher education. The sample was mostly composed by omnivorous and flexitarians (over 80% in all three countries). The subjects were asked if they intended to change their diet to a plant- based diet on a scale of Likert from 1 to 7, and the results show responses with a greater tendency to change, over 5 points in most of the sample. Although most of the respondents were omnivorous and flexitarians, a tendency to have a willingness to change was observed, either to improve health or due to the knowledge of global warming. This indicates that a structural change can be made in the public policies of the countries to generate a real change. The willingness to change diet was positively affected by the higher consumption of fruits and vegetables and negatively affected by the higher consumption of red meat, this finding can be due to the deep-rooted customs of consuming meat in Latin American countries as a main course, consumers have a limitation of conceiving food without products of animal origin as the center of the main dish. Knowledge also affected the will, the more knowledge regarding global warming and association with diet, the more will to change (BR. p 0.0002).and lastly the more awareness of the benefits of a Mediterranean type of diet increased significantly the will of change (CL. p 0.0004). The association of knowledge, awareness and willingness to change has been seen in other cultures and gives us hope to make changes in education from childhood, awareness campaigns for the population and educate health professionals to have a more educated and awareness countries, to achieve true changes, not only at the health level of individuals, but also globally to fight the damage that the industry generates in the environment. ii PREFACE This report presents the work of a master thesis that acts as the final paper in the conclusion of the Master of Science degree in Food Innovation and Health at the faculty of science at the University of Copenhagen. The first part of the report systematically reviews the literature published on global warming in Latin American countries, diet, and health, and the second part refers to an online survey among selected Latin American countries to determine the readiness to move toward a plant-based diet. Associate Professor Federico Jose Armando Perez-Cueto Eulert from the Section of Food Design and Consumer Behaviour, University of Copenhagen, and Associate Professor Christian Ritz from the Department of Nutrition, Exercise, and Sports, Pediatric and International Nutrition, University of Copenhagen, supervised the thesis. The theoretical part of the thesis was conducted at the Department of Food Science, Section of Food Design and Consumer Behaviour at the University of Copenhagen from February to August 2019. iii INDEX ABSTRACT i PREFACE iii INDEX iv LIST OF FIGURES AND TABLES vii LIST OF ABBREVIATIONS ix BACKGROUND Definitions 1 Background 2 SECTION 1 8 Systematic review Introduction 9 Aim 10 Research question 10 Methodology 11 Results 12 Diet and global warming 16 Plant based diet and health 16 Implication and social motivation of vegetarianism and 17 veganism Undergraduate thesis 20 Discussion 22 Conclusion 24 iv SECTION 2 25 Online survey and analysis to determine readiness to move towards a plant-based diet in Latin American countries Introduction 26 Research question 28 Study design Data collection 28 Questionnaire 29 Data analysis 30 Results Sociodemographic description of the sample 31 Willingness to move towards a PBD 32 Frequency of consumption 33 Willingness to move towards a PBD influenced by frequency of 34 consumption Willingness to move towards a PBD influenced by knowledge 35 Willingness to move towards a PBD influenced by awareness 37 regarding GW and PBD Barriers and facilitators 38 Intention to change diet influence by barriers and facilitator 39 Willingness to change diet influence by barriers and facilitator 42 Barriers and facilitators influence by diet 44 Intention to change diet and motives 47 Intention to change diet and motives for parents 50 v Discussion The sample 53 Willingness to Move Toward a Plant-based Diet 54 Frequency of Consumption 55 Willingness to Move Toward a PBD Influenced by Knowledge 55 and Awareness Regarding GW and PBD Barriers and Facilitators 56 Intention to Change Diet and Motives 57 Limitations and strength 58 Conclusion 59 REFERENCES 60 APPENDICES 67 Appendix Nº1 survey 67 Appendix Nº2 commands for Rstudio 72 vi LIST OF FIGURES AND TABLES Tables Table 1: Methodology 11 Figure 1: Screening of articles 12 Table 2: Analysis of articles 13 Table 3: Analysis of included theses 19 Table 4: Socio demographic characteristics of the sample 31 Figure 2: Willingness to move towards a plant based diet 32 Table 5: Frequency of consumption descriptive 33 Table 6: Willingness to move towards a PBD influenced by frequency 34 of consumption of certain groups of food Table 7: Willingness to move towards a PBD influenced by knowledge 36 of specific statements Table 8: Willingness to move towards a PBD influenced by awareness 37 regarding GW and PBD Table 9: Barriers and facilitators descriptive analysis 39 Table 10: Intention to change diet influence by barriers and facilitator 41 Table 11: Willingness to change diet influence by barriers and 43 facilitator Table 12: Barriers and facilitators influenced by diet (part 1) 45 Table 12: Barriers and facilitators influenced by diet (part 2) 46 Figure 3: Intention to change to a PBD 47 Figure 4: Motives to change to a PBD 48 Figure 5: Motives to NOT change to a PBD 49 vii Figure 6: Intention to change to a PBD for parents 50 Figure 7: Motives to change to a PBD for parents 51 Figure 8: Motives to NOT change to a PBD for parents 52 viii LIST OF ABBREVIATIONS • W: Willing. • GW: global warming. • PBD: plant-based diet. • WTC: willingness to change. • A: Agreement. • OCDE: organization for cooperation and economic develop (by their Spanish initials). • UK: United Kingdom. • FAO: Food and agriculture organization of the united nations. • EEUU: United states of America. • LATAM: Latin American countries (by their Spanish initials). • BL: Bolivia. • BR: Brazll. • CL: Chile. • FBDG: food based dietary guidelines. ix BACKGROUND Definitions Before starting, it is important to set some definitions for better understanding of this document. The association of U.K. dietitians defines a plant-based diet as a diet based on foods derived from plants that include a few or no animal products (Garton & Hood, 2017). However, there is still no consensus about the definition of a plant-based diet. Authors define this as minimally processed food, which includes fruits, vegetables, legumes whole grain, nuts and seed and excludes all animal products (Ostfeld, 2017). For this dichotomy, it is important to not only define the concept of a plant-based diet but also the different types of plant-based diets found in the literature. In this document, a plant-based diet is defined as follows: “A diet based on foods derived from plants, such as fruits, vegetables, legumes, whole grains, nuts, and seed, and with few or no animal product include.” The definition of a plant-based diet comprises many diets, which have been defined as follows: Veganism: this form of diet excludes all types of animal-derived products from its daily plan (Melina, Craig, & Levin, 2016). Vegetarianism: this form of diet excludes all types of flesh foods, such as meat, poultry, and seafood (Baroni, Goggi, & Battino, 2018). Pescetarianism: this form of diet contains fish or seafood, but no meat (Dagnelie & Mariotti, 2017b).

  • Beginners Guide to Being a Pescetarian
    P E S C E T A R I A N 1 0 1 a G u i d e t o B e c o m i n g P e s c e t a r i a n FOREWORD Now that our blog has been active for a little while now, Matt and I decided to create this ebook so that we could answer some of those questions that I know we had when we first became pescetarian, as well as some of the questions we’ve received from you guys on the blog and through social media. So this ebook is going to take you through some of the basics of pescetarianism, including how to nurture a healthy pescetarian diet and how to shop for fish and seafood in a sustainable way. We’ve even included a few of our favourite recipes to help you get started! What is a Pescetarian? Quite simply, a pescetarian is someone who eats fish and seafood, but no other meat. Pescetarians do eat dairy products, such as milk and cheese, in addition to vegetables, nuts pulses and fruit. The term pescetarian comes from “pesce” which is the Italian word for fish and whilst the term has been around for a number of years (it found its way into the dictionary in 1993) it has only become widely known and heard in the last 5 years or so. Why We Became Pescetarians Laura: I’ve tried loads of different diets over the years. I grew up eating meat, however in my adolescence and adulthood I tried being both vegetarian and vegan before settling on being a pescetarian.

    SLOW DOWN, FAST FASHION! Sustainability Month continues with Sustainable Fashion Week. This week, the conversation will be centered around fast fashion and its environmental impact. Our friends at OCCU are planning a discussion on that topic which will highlight different perspectives on fast fashion alongside the potential ways in which our society can make a transition to a more sustainable fashion without compromising one's sense of style. Keep an eye on OCCU's social media for updates! P.S. I thought the picture above would be a perfect illustration for the throwaway fashion culture: what the pretty lady is wearing today will end up on a landfill tomorrow together with other pieces of evidence denouncing our consumerism. MAKING AN EASY AUTUMN COLLAGE The leaves on the trees are beginning to change colors to deep auburn, rich crimson, and dazzling yellow, and fall to the ground. One can lovingly take them out of the nutrient cycle and immortalize their fading beauty in a collage. Follow the 4 step guide found below to frame your own piece of autumn. LEARN HOW TO MAKE ONE SPOTLIGHT We've heard about the harmful effects of fast fashion on the environment and communities: greenhouse and noxious gas emissions, water pollution, poor work conditions of the industry workers, and tons of waste in landfills. It is time to ask the question, How can we dress sustainably? Another, question is, How can cultural venues and the entertainment industry be sustainable in terms of fashion? Greer King, a college senior who creates costumes for the theater, is a person who has long been concerned about these issues.

Social Inequality and Diet: Understanding Stratified Meat Consumption Patterns in Germany © Laura Einhorn 2020 Published by IMPRS-SPCE International Max Planck Research School on the Social and Political Constitution of the Economy, Cologne imprs.mpifg.de ISBN: 978-3-946416-20-3 DOI: 10.17617/2.3256843 Studies on the Social and Political Constitution of the Economy are published online on imprs.mpifg.de. Go to Dissertation Series. Studies on the Social and Political Constitution of the Economy Abstract Based on a complementary mixed-methods design, the dissertation sheds light on the relationship between meat consumption practices and consumers’ socioeconomic po- sition. In a first step, two large-scale data sets, the German Einkommens- und Ver- brauchsstichprobe (EVS) 2013 and the Socioeconomic Panel (GSOEP) 2016, are used to establish empirical relationships between meat consumption practices and consumers’ socioeconomic position. Education and income do not show the same effects across social groups. Income most strongly affects the meat consumption patterns of low-in- come consumers, and income effects diminish as income increases. Furthermore, in- come does not make much of a difference for consumers with low levels of education. Meat-reduced and meat-free diets are also more common among students and among self-employed persons, even after controlling for income and education. Income does not necessarily influence the amount of meat that is consumed but the type and price of the meat purchased.

  • Paths to Pescetarianism
    Copyright 2010 by Eric Lai ii Acknowledgments This work would not have been possible without the support and dedication of an entire array of exceptional people. I want to begin by expressing my sincerest gratitude to everyone at the Department of Social and Behavioral Sciences at the University of California, San Francisco. From the day I was offered the opportunity to enroll in the PhD program, the department has been unbelievably accommodating, helpful, and understanding — especially when I decided to move cross-country from San Francisco to pursue opportunities in Washington, DC. Even with 3,000 miles of distance often separating me from the Bay, I believe the process leading to the completion of this dissertation could not have been smoother — a true testament to SBS’s faculty and staff. My dissertation committee — Howard Pinderhughes, Charlene Harrington, Bob Newcomer, and Warren Belasco — could not be more deserving of my unmitigated praise and appreciation. Howard has been a truly wonderful and inspiring dissertation chair; he provided invaluable direction as I decided on a research topic, and at every turn he encouraged me to explore new possibilities, angles, and dimensions with this work. As my third area chair and then as a committee member, Charlene offered discerning and thoughtful suggestions as the project came to fruition. Bob’s insightful commentary helped me stay cognizant of the broader implications of this study. Finally, this project would not have been the same without Warren, who agreed to serve as a committee member without any prior familiarity with my work. He is an outstanding scholar of food and culture, and his perspectives were instrumental to the completion of this project.

  • Breastfeeding Intentions and Practices Among the Different
    BREASTFEEDING INTENTIONS AND PRACTICES AMONG THE DIFFERENT VEGETARIAN GROUPS IN THE UNITED STATES by ANNE MORGAN ARMSTRONG (Under the Direction of Alex Kojo Anderson) ABSTRACT This study assessed breastfeeding intentions and practices among vegetarians in the United States. Study aims were to examine the potential differences in feeding intentions and practices of the vegetarian types. This was a cross-sectional online survey of female vegetarians (N = 266) with the survey link emailed to vegetarian listservs administrators for membership completion. Participants were primarily Caucasian (77%) and an average age of 33.8±11.1 years. Overall, participants’ breastfeeding intention, including exclusive breastfeeding, was higher than actual breastfeeding practice, irrespective of vegetarian type. Being a pesco vegetarian was associated with higher likelihood of intention to breastfeed (OR = 6.60, 95% CI: 1.12-38.60) compared to being a flexitarian. There was no significant difference between breastfeeding practices by vegetarian type. Future studies of a larger and a more heterogeneous sample are needed to ascertain breastfeeding practices among vegetarians to inform the design of effective interventions aimed at promoting breastfeeding among vegetarians.

In this paper, we present a flexible model of vegetarian and vegan dietary 17 choices, and derive the joint dynamics of rates of consumption. We fit our model to a 18 pseudo-panel with 23 years of U.K. household data, and find that while vegetarian 19 rates are largely determined by current household characteristics, vegan rates are 20 additionally influenced by their own lagged value. We solve for equilibrium rates of 21 vegetarianism and veganism, show that rates of consumption return to their 22 equilibrium levels following a temporary event which changes those rates, and 23 estimate the effects of campaigns to promote non-meat diets.

  • Vegetarians” Eat Seafood and Implications for the Vegetarian Movement
    What about Fish? Why Some “Vegetarians” Eat Seafood and Implications for the Vegetarian Movement Kate D. McPherson Center for Animals and Public Policy, Tufts University Cummings School of Veterinary Medicine, 200 Westboro Rd, Grafton, MA, USA 01536 [email protected] 1 Vegetarians do not consume the flesh of animals but may choose to consume certain animal byproducts. However, many self-identified vegetarians continue to eat fish and seafood, despite claiming membership to a group that is morally opposed to killing animals for food. Collective identity within social movements is essential to group solidarity and effectiveness, and differing collective identities within movements can lead to internal division. This study sought to identify the reasons that some “vegetarians” will abstain from meat but continue to eat fish and seafood, and the resulting implications for the vegetarian movement as a whole. Analysis of discussions from seven online forums reveals a lack of shared understanding of the definitions of “vegetarian” and “meat” and lack of familiarity with the term “pescetarian”, a person who abstains from all animal flesh except fish and seafood. A lack of consensus for which animals deserve protection under the vegetarian movement is also present. Definitions of vegetarianism, justifications for consuming fish, the social influences at work among pescetarians, and the resulting implications for the vegetarian movement are discussed. Keywords: vegetarian, pescetarian, fish consumption, collective identity, vegetarian movement 2 Introduction Vegetarianism has been around since ancient times, but has only begun to take shape as a social movement in the United States since the mid 1800s (Roe, 1986; Whorton, 1994).

  • VEGETARIAN, VEGAN, and PESCETARIAN CONSUMERS and THEIR PARTICIPATION in the GREEN MOVEMENT by CORY T. KING
    VEGETARIAN, VEGAN, AND PESCETARIAN CONSUMERS AND THEIR PARTICIPATION IN THE GREEN MOVEMENT by CORY T. KING A thesis submitted in partial fulfillment of the requirements for the Honors in the Major Program in Marketing in the College of Business Administration and in the Burnett Honors College at the University of Central Florida Orlando, Florida Spring Term 2014 Thesis Chair: Dr. Carolyn Massiah ABSTRACT Entering into the 21st century, sustainable living has become a popular topic of concern for scientists and engineers, politicians, news reporters and individuals alike. Most importantly though, sustainable living has become popular to the modern consumer, and many firms are attempting to understand and cater their efforts to the ecologically conscious consumer. Previous studies have shown that the use of psychographics, as opposed to demographics, result in more significant results that can help firms identify ecologically conscious consumers. The purpose of this thesis is to examine the relationship between consumers who identify as pescetarian, vegetarian, or vegan, and their respective participation in the green movement in terms of their pro-environmental attitudes and their purchase behaviors. Consumers’ reason for choosing an alternative diet, their relative commitment to the alternative diet, as well as their level of green participation based on the New Ecological Paradigm (NEP) scale and the Ecologically Conscious Consumer Behavior (ECCB) scale was measure and analyzed. Additionally, a conclusion and discussion of the study, potential marketing implications, and suggestions for future studies will be reviewed. ii DEDICATIONS To my family, who has supported me in all of my endeavors. To my professors, who have inspired me and supplied me with the knowledge I required to take on this project.
