Ethical concerns regarding animal use mediate the relationship between variety of pets owned in childhood and vegetarianism in adulthood

Prevalence and determinants of orthorexia nervosa among Turkish adolescents

PURPOSE

Given the prevalence and diversity of eating issues among adolescents, understanding the epidemiological aspects of orthorexia nervosa (ON) in this demographic, along with identifying associated clinical factors, sociodemographic traits, eating habits and parental attitudes, holds paramount importance both clinically and scientifically. This study aimed to ascertain the prevalence of ON among Turkish high school adolescents aged 14-18 and explore potential correlates of this clinical condition.

METHOD

In the initial phase, 1784 adolescents completed the Data Form, Orthorexia Nervosa Inventory (ONI) and Parent Style Scale (PSS), while their parents filled out the the parental version of the revised Child Anxiety and Depression Scale (RCADS). Subsequently, clinical interview and The Kiddie-Schedule for Affective Disorders and Schizophrenia for School Aged Children, Present and Lifetime Version (KD-SADS-PL) were conducted with 9 adolescents with high risk for ON to assess comorbidities.

RESULTS

The study revealed ON prevalence of 0.5%, with 0.3% in boys and 0.6% in girls. Rural residency, dietary supplement use, and pet ownership correlated with higher ONI scores (p = 0.022, p = 0.002, p = 0.042 respectively). OCD and panic disorder symptoms (B = 0.307, p < 0.001 and B = 0.165, p = 0.018 respectively), increased BMI, and anxiety scores were associated with elevated ONI scores. Authoritarian parenting was significantly related to ONI total scores (B = 1.69, p = 0.018).

CONCLUSION

This study significantly contributes to the literature by delineating the prevalence of ON in adolescents, identifying associated risk factors, elucidating psychopathological associations of orthorexic symptoms, and identifying the relationship between parenting styles and ON. Such insights into the factors influencing ON can aid in demystifying its nature.

The Ethics of Veganism

In this article, we discuss the ethics of veganism by looking at the moral implications of having a vegan diet or plant-based diet. Veganism is a way of diet that forbids or avoids consuming any animal products. It has drawn a lot of interest recently due to awareness or trends of vegan diet, human health, and ethical behavior benefits. The aim of the research is to look into the moral values that talk about veganism, such as animal welfare, environmental sustainability, and human welfare. In this study, we conduct a thorough assessment of ethical theories and actual evidence in an effort to know about the ethical reasons for veganism and its larger societal impacts. Through an analysis of existing literature and clinical studies, we discuss the various challenges, advantages, lifestyle modification, and nutritional concerns related to a vegan diet.

Bodybuilders and high-level meat consumers' behavior towards rabbit, beef, chicken, turkey, and lamb meat: A comparative review

In bodybuilders' diets, protein plays a crucial role in supporting muscle growth and repairing damaged muscle tissue. These individuals meet their protein needs by combining dietary sources with supplements. Animal-based proteins are often preferred over plant-based proteins because they are believed to better support muscle protein synthesis. This review explores the meat consumption patterns of bodybuilders and high-level meat consumers, focusing on rabbit, beef, chicken, turkey, and lamb. We describe and compare the types of meat bodybuilders commonly consume and provide an overview of protein supplements, including meat-based options, plant-based alternatives, and whey-based products. Our aim is to gain insight into the dietary preferences of bodybuilders and high-level meat consumers, considering their nutritional requirements and the potential effect on the meat industry. We conducted an extensive search across various databases, including Scopus, Web of Science, PubMed, and Google Scholar. We found that individual choices vary based on factors such as attitudes, trust, taste, texture, nutritional content, ethical considerations, and cultural influences. Nutritional factors, including protein content, amino acid profiles, and fat levels, significantly influence the preferences of bodybuilders and high-level meat consumers. However, it is crucial to maintain a balance by incorporating other essential nutrients such as carbohydrates, healthy fats, vitamins, and minerals to ensure a complete and balanced diet. The findings from this review can inform strategies and product development initiatives tailored to the needs of bodybuilders and discerning meat enthusiasts.

Exploring the role of our contacts with pets in broadening concerns for animals, nature, and fellow humans: a representative study

While pet ownership is normative in many occidental countries, whether humans' proximal contacts with pets have implications for attitudes and behaviors toward other (non pet) animals, nature, and fellow humans, has received limited empirical attention. In a large representative sample, we investigate whether pet ownership and positive contact with pets are associated with more positive attitudes and heightened concerns for non-pet animals, nature, and human outgroups. A cross-sectional questionnaire survey was conducted among Canadian adults (619 pet owners, 450 non-pet owners). Pet owners reported more positive attitudes toward non-pet animals (e.g., wild, farm animals), higher identification with animals, more positive attitudes toward human outgroups, higher biospheric environmental concerns, higher human-environment interdependence beliefs, and lower usual meat consumption. Positive contact with pets was also associated with most of these outcomes. Solidarity with animals, a dimension of identification with animals, emerged as a particularly clear predictor of these outcomes and mediated the associations between positive contact with pets and positive attitudes toward non-pet animals, biospheric, egoistic, and altruistic environmental concerns, human-environment interdependence beliefs, and diet. Our results provide support for the capacity of pets to shape human consideration for a broad range of social issues, beyond the specific context of human-pet relations.

Could Gut Microbiota Composition Be a Useful Indicator of a Long-Term Dietary Pattern?

Despite the known effects of diet on gut microbiota composition, not many studies have evaluated the relationship between distinct dietary patterns and gut microbiota. The aim of our study was to determine whether gut microbiota composition could be a useful indicator of a long-term dietary pattern. We collected data from 89 subjects adhering to omnivorous, vegetarian, vegan, and low-carbohydrate, high-fat diet that were equally distributed between groups and homogenous by age, gender, and BMI. Gut microbiota composition was analyzed with a metabarcoding approach using V4 hypervariable region of the 16S rRNA gene. K-means clustering of gut microbiota at the genus level was performed and the nearest neighbor classifier was applied to predict microbiota clustering classes. Our results suggest that gut microbiota composition at the genus level is not a useful indicator of a subject's dietary pattern, with the exception of a vegan diet that is represented by a high abundance of Prevotella 9. Based on our model, a combination of 26 variables (anthropometric measurements, serum biomarkers, lifestyle factors, gastrointestinal symptoms, psychological factors, specific nutrients intake) is more important to predict an individual's microbiota composition cluster, with 91% accuracy, than the dietary intake alone. Our findings could serve to develop strategies to educate individuals about changes of some modifiable lifestyle factors, aiming to classify them into clusters with favorable health markers, independent of their dietary pattern.

Plant-based and vegetarian diets: an overview and definition of these dietary patterns

PURPOSE

This paper aims to present an overview of the definitions of "plant-based and "vegetarian diets" adopted by different organizations worldwide, proposing new standard definitions and discussing the notion of vegetarianism as a restrictive dietary pattern.

METHODS

An extensive literature review on the different definitions of vegetarian and plant-based diets was conducted. Definitions of different international vegetarian and vegan organizations were also taken into account. Objective definitions for vegetarian and plant-based diets, as well as for their subcategories, were proposed. Other aspects related to how vegetarian diets are viewed and defined were also discussed.

RESULTS

We proposed that a vegetarian diet should be defined as "a dietary pattern that excludes meat, meat-derived foods, and, to different extents, other animal products". This definition would include, among others, ovolactovegetarian and vegan diets. The proposed definition for a plant-based diet was "a dietary pattern in which foods of animal origin are totally or mostly excluded". Other types of diets, such as flexitarian and pescetarian diets, could be considered plant-based. A vegetarian diet should not be considered restrictive. Instead, terms such as alternative or non-conventional could be used to define it and to distinguish it from the conventional diet adopted by most of the Western population.

CONCLUSION

This paper was able to elaborate objective definitions of vegetarian and plant-based diets. Standardizing nomenclatures may reduce misinterpretation and confusion in this field of study.

Moral decision-making in pettism: The influence of animal type, pet ownership status, and social distance

Speciesism prioritizes humans over animals and pets. Nevertheless, pet owners have a strong attachment bond with their pets, which makes their hierarchical view of pets less clear. Aiming to examine this issue, we present a dilemma involving animals and humans that allowed us to investigate whether animal type, social distance, and pet ownership status can affect moral decision-making related to pets. Save-willingness results showed that in the moral dilemmas of pets versus livestock versus wild animals (Studies 1a and 2a) and their own pets versus strangers (Studies 1b and 2b), pet owners prioritize pets whereas non-owners prioritize pets (Studies 1a and 2a) and strangers (Studies 1b and 2b). Pet owners prefer to save pets more than do non-owners (Study 1a), and this effect was only observed in females (Study 2a). Save-decision results showed that in the moral dilemmas of pets versus livestock versus wild animals (Study 2a), pet owners prioritize pets whereas in the dilemmas of pets versus strangers (Study 2b), pet owners prioritize strangers. The same result was found in non-owners. Pet owners prefer more than do non-owners to save pets (Study 2). Overall, the separation of save-willingness and save-decision results revealed that pet owners show special speciesism (i.e., pettism).

Exploring user-generated content related to vegetarian customers in restaurants: An analysis of online reviews

This study aimed to explore and evaluate factors that impact the dining experience of vegetarian consumers within a range of vegetarian-friendly restaurants. To explore the factors and understand consumer experience, this study analyzed a vast number of user-generated contents of vegetarian consumers, which have become vital sources of consumer experience information. This study utilized machine-learning techniques and traditional methods to examine 54,299 TripAdvisor reviews of approximately 1,008 vegetarian-friendly restaurants in London. The study identified 21 topics that represent a holistic opinion influencing the dining experience of vegetarian customers. The results suggested that "value" is the most popular topic and had the highest topic percentage. The results of regression analyses revealed that five topics had a significant impact on restaurant ratings, while 12 topics had negative impacts. Restaurant managers who pay close attention to vegetarian aspects may utilize the findings of this study to satisfy vegetarian consumer requirements better and enhance service operations.

Is pet ownership associated with values and attitudes towards animals?

In Organisation for Economic Co-operation and Development (OECD) countries, the number of pets and pet owners has been increasing in recent years. The experiences people have with pets might impact their relationships with animals in general and especially attitudes towards animal protection and use. However, research on the impact of pet ownership on values and attitudes towards animals is relatively scarce. We analyse associations of pet ownership with different values and attitudes towards animals. We derived seven attitude constructs towards animals from three different datasets using Principal Component Analyses. Data were collected using standardised online surveys with German residents (dataset 1 = 1,049 respondents; dataset 2 = 414 respondents; dataset 3 = 1,048 respondents). All three samples are non-probability quota samples. The seven attitudinal constructs represent values and attitudes towards animals ranging from general values and attitudes towards, eg animal protection, to more specific attitudes towards, eg eating animals. We analysed the relationship of pet ownership, sex, and age with these constructs using ANOVA. Our results show that effect sizes are small to medium. Pet ownership has the strongest association with more general values and attitudes towards animals, with pet owners being, eg more involved in animal protection and more in favour of awarding fundamental rights to animals. In contrast, we found that more specific attitudes, such as the evaluation of current pig farming systems or attitudes towards eating meat, were more related to sex than pet ownership. Our findings indicate that having pets relates to their owners' attitudes towards animals, but that this association varies depending on the specificity of attitudes.

Meat as a Pharmakon: An Exploration of the Biosocial Complexities of Meat Consumption

In contemporary dietary advice, meat is depicted as a pharmakon: it is believed to either heal or poison the human body (and mind). Often, it also serves as a scapegoat for a wide range of public health issues and other societal problems. Related attitudes, practices, and beliefs pertain to a demarcated mode of thinking or episteme that is characteristic for the so-called post-domestic or industrialized societies. The latter are not only typified by an abundant yet largely concealed production of meat, but increasingly also by moral crisis and confusion about its nutritional meaning. For an improved appreciation of the ambiguous position of meat in human health and disease, as well as the concomitant scattering into different subject positions (e.g., the omnivore, flexitarian, vegetarian, vegan, permaculturalist, and carnivore position), an interdisciplinary approach is required. To this end, the current study tentatively combines food research with a selection of (post-structuralist) concepts from the humanities. The aim is to outline a historical and biosocial need for meat (as well as its rejection) and to analyze how its transformative effects have contributed to a polarized discourse on diet and well-being in academia and society at large. Excessive categorization (for instance with respect to meat's alleged naturalness, normalness, necessity, and niceness) and Manichean thinking in binary opposites are among the key factors that lead to impassioned yet often sterile debates between the advocates and adversaries of meat eating in a post-truth context.
