Animal board invited review: Animal source foods in healthy, sustainable, and ethical diets - An argument against drastic limitation of livestock in the food system.

Animal source foods are evolutionarily appropriate foods for humans. It is therefore remarkable that they are now presented by some as unhealthy, unsustainable, and unethical, particularly in the urban West. The benefits of consuming them are nonetheless substantial, as they offer a wide spectrum of nutrients that are needed for cell and tissue development, function, and survival. They play a role in proper physical and cognitive development of infants, children, and adolescents, and help promote maintenance of physical function with ageing. While high-red meat consumption in the West is associated with several forms of chronic disease, these associations remain uncertain in other cultural contexts or when consumption is part of wholesome diets. Besides health concerns, there is also widespread anxiety about the environmental impacts of animal source foods. Although several production methods are detrimental (intensive cropping for feed, overgrazing, deforestation, water pollution, etc.) and require substantial mitigation, damaging impacts are not intrinsic to animal husbandry. When well-managed, livestock farming contributes to ecosystem management and soil health, while delivering high-quality foodstuffs through the upcycling of resources that are otherwise non-suitable for food production, making use of marginal land and inedible materials (forage, by-products, etc.), integrating livestock and crop farming where possible has the potential to benefit plant food production through enhanced nutrient recycling, while minimising external input needs such as fertilisers and pesticides. Moreover, the impacts on land use, water wastage, and greenhouse gas emissions are highly contextual, and their estimation is often erroneous due to a reductionist use of metrics. Similarly, whether animal husbandry is ethical or not depends on practical specificities, not on the fact that animals are involved. Such discussions also need to factor in that animal husbandry plays an important role in culture, societal well-being, food security, and the provision of livelihoods. We seize this opportunity to argue for less preconceived assumptions about alleged effects of animal source foods on the health of the planet and the humans and animals involved, for less top-down planning based on isolated metrics or (Western) technocratic perspectives, and for more holistic and circumstantial approaches to the food system.

Temporal variation in food consumption of Brazilian adolescents (2009-2015).

BACKGROUND: Worldwide population has been increasingly exposed to ultra-processed foods, which are associated with obesity. Adolescence is a transition period of life and WHO recommends the surveillance of risk factors to the adolescents' health, such as diet, because experiences in this phase can result in health risks. OBJECTIVE: To assess the trends in food consumption of adolescents from Brazilian capitals according to sociodemographic variables, based on data from the National Survey of School Health (PeNSE). METHODS: Data from in 2009, 2012 and 2015 of a total of 173,310 9th graders enrolled in public and private schools in Brazilian capitals and in the Federal District were assessed. Food consumption was assessed from regular consumption (five or more times a week) of healthy eating markers (beans; vegetables; fruit) and unhealthy eating markers (sweets; soft drinks; fried salty snacks). For sociodemographic variables, we considered macro regions; age; race/ skin color; gender; school administrative status. We assessed these markers trends for the population and, additionally, the analyses were stratified by gender, race/ skin color, and school administrative status. Statistical significance of the temporal trends was assessed by linear regression model. RESULTS: Over six years, three types of change in Brazilian adolescents' diet were observed: decreasing regular consumption of beans, sweets and soft drinks, increasing regular consumption of vegetables, and stable consumption of fruit and fried salty snacks. CONCLUSION: Brazilian adolescents' diet composition has changed in a short period, and therefore it is necessary to monitor it to propose actions aimed at this public.

The ethics of Halal meat consumption: preferences of consumers in England according to the method of slaughter.

BACKGROUND: The continued growth of the global Halal meat market has resulted in many mainstream businesses in the developed world trading in Halal products. A good understanding of Halal consumer behaviour with regard to their preference of meat according to the method of slaughter (pre-stunned or not) and the frequency of consumption is vital for the formulation of future animal welfare legislation, consumer protection policies and research strategies of educational institutions. METHODS: In this study, 250 Halal meat consumers in England were surveyed to obtain a better understanding of their meat consumption frequency, preference of meat according to species of animals and the method of slaughter. RESULTS: The results show that the majority (50.8 per cent) of consumers ate meat at least once a week, 45.6 per cent at least once a day, 3.2 per cent at least once a month and 0.4 per cent ate meat occasionally. Poultry meat was marginally the most preferred meat among respondents overall, followed by lamb and beef, with the majority of respondents (approximately 70 per cent) indicating preference for meat from animals slaughtered without stunning over those stunned before slaughter. There were gender differences within some responses. CONCLUSION: The results give an insight into Halal consumer behaviour, and may be useful to retailers, researchers, consumer advocates, animal welfare charities and government.

Identity and the Ethics of Eating Interventions.

Although "you are what you eat" is a well-worn cliché, personal identity does not figure prominently in many debates about the ethics of eating interventions. This paper contributes to a growing philosophical literature theorizing the connection between eating and identity and exploring its implications for eating interventions. I explore how "identity-policing," a key mechanism for the social constitution and maintenance of identity, applies to eating and trace its ethical implications for eating interventions. I argue that identity policing can be harmful and that eating interventions can subject people to these harms by invoking identity policing qua intervention strategy or by encouraging people to eat in ways that subject them to policing from others. While these harms may be outweighed by the benefits of the intervention being promoted, they should nonetheless be acknowledged and accounted for. To aid in these evaluations, I consider factors that modulate the presence and severity of identity-policing and discuss strategies for developing less harmful eating interventions. I conclude by considering the relationship between identity-policing and identity loss caused by long-term diet change. This paper contributes to the centering of identity in food ethics and to a more comprehensive picture of identity's ethical importance for eating interventions.

Nudging, formulating new products, and the lifecourse: A qualitative assessment of the viability of three methods for reducing Scottish meat consumption for health, ethical, and environmental reasons.

Most governmental initiatives designed to improve dietary and planetary health have adopted a light-touch informing approach. However, it may be necessary to consider more direct measures that go beyond simply informing the public if the current high levels of meat consumption in Scotland are to be addressed. This paper considers three possible avenues through which more sustainable meat consumption patterns may be promoted: 'nudging', the formulation of new meat-alternative products, and targeting those in particular stages of the lifecourse. Through focus groups held in various locations in Scotland, the perceived viability of these measures was explored. While each measure shows some promise for reducing Scottish meat intake, the complex nature of food choice means that more qualitative research into meat consumption in Scotland is required.

Dealing with the meat paradox: Threat leads to moral disengagement from meat consumption.

Meat consumption is conflicted, because meat provides pleasure to many people, but it also causes animals to suffer. This so-called meat paradox elicits discomfort in meat-eaters and they try to reduce their discomfort, for example, by means of moral disengagement. In the present investigation, we tried to scrutinize this process and examine the boundary conditions that increase moral disengagement. We assumed that, due to a domain general action-oriented state, people tend to resolve the meat paradox via moral disengagement, even if inconsistency is elicited in a different, not food-related domain. Two experiments were conducted, in which we assessed people's moral disengagement efforts via ambivalence measures after we induced inconsistency using different threats in meat-unrelated domains. Supporting our assumptions, people showed reduced ambivalence towards food in affective priming (Experiment 1) and Mouse-Tracker tasks (Experiment 2) after experiencing inconsistency. In fact, plant-based dishes became more positive and meat dishes more negative after inconsistency was induced, indicating that people disguise their endorsement of meat. This provides first convergent evidence that an inconsistency induced action-oriented state may influence cognitions regarding the meat paradox.

Challenges in conducting clinical nutrition research.

Clinical nutrition research has played a pivotal role in establishing causality between diet or nutrient intake and health outcome measures and in the determination of dietary requirements and levels of supplementation to achieve specific outcomes. Because the studies are performed with humans, clinical nutrition research can be readily translated into public health messages. However, there are many challenges and considerations unique to the field, such as the baseline nutritional status of study participants, defining appropriate control groups, effective blinding of participants and investigators, the evolving ethics of randomized control trials, and a tension in a priori decisions regarding inclusion of nutritionally vulnerable participants versus representative samples of general populations. Regulatory approvals that place increasing burdens on the ability of investigators to carry out and complete research protocols have grown dramatically in recent years. There is much room for improved efficiency in the approval and reporting processes aimed at protecting volunteers and providing transparency to the public. Decreased redundancy would have a direct benefit to clinical nutrition research and investigators. Despite these challenges, the information to be gained and the rewards of clinical nutrition research remain high.

Genetic modification technology for nutrition and improving diets: an ethical perspective.

Genetically modified (GM) techniques to improve the nutrition and health content of foods is a highly debated area riddled with ethical dilemmas. Assessing GM technology with a public health ethical framework, this paper identifies public health goals, the potential burdens of the technology, and areas to consider for minimizing burdens and ensuring beneficence, autonomy, and little infringements on justice. Both policymakers and food producers should acknowledge local food environments and the agricultural context of each community in order to effectively prepare communication strategies and equitably distribute any proposed GM food intervention.

Consumers' environmental and ethical consciousness and the use of the related food products information: The role of perceived consumer effectiveness.

Consumers can be important active contributors to a sustainable society by selecting food choices that are both healthy and produced respecting environmental and socially ethical standards. The current study investigates five consumer behavioural factors - namely, perceived consumer effectiveness (PCE); environmental conscious behaviour; concerns for ethical food production; health conscious lifestyle; and healthy dietary patterns. The key interest of the study lies in exploring the moderating role of PCE - the extent to which the consumer believes that his/her own efforts can make a difference - in these interrelationships. The empirical analysis was conducted through an online survey of food consumers implemented in three markets - the US, the UK and Germany. Findings indicate that for individuals with higher levels of PCE, who are environmental conscious and ethically concerned, information on food labels relating to environmental and social issues represents value by itself. Interestingly, health and nutrition information on food labels was not perceived valuable by consumers with high PCE. The predictive effects of various socio-demographic variables on PCE, consumer environmental and health consciousness are discussed. Cross-cultural differences are also outlined. The results of this research may contribute to the development of environmental policies and communication strategies of the food industry to enhance perceived consumer effectiveness among consumers. Improved PCE, in turn, may catalyze consumers' environmental behaviour and ethical concerns in relation to consumption of food products with environmental and social information.

Genetically Modified (GM) Foods and Ethical Eating.

The ability to manipulate and customize the genetic code of living organisms has brought forth the production of genetically modified organisms (GMOs) and consumption of genetically modified (GM) foods. The potential for GM foods to improve the efficiency of food production, increase customer satisfaction, and provide potential health benefits has contributed to the rapid incorporation of GM foods into the American diet. However, GM foods and GMOs are also a topic of ethical debate. The use of GM foods and GM technology is surrounded by ethical concerns and situational judgment, and should ideally adhere to the ethical standards placed upon food and nutrition professionals, such as: beneficence, nonmaleficence, justice and autonomy. The future of GM foods involves many aspects and trends, including enhanced nutritional value in foods, strict labeling laws, and potential beneficial economic conditions in developing nations. This paper briefly reviews the origin and background of GM foods, while delving thoroughly into 3 areas: (1) GMO labeling, (2) ethical concerns, and (3) health and industry applications. This paper also examines the relationship between the various applications of GM foods and their corresponding ethical issues. Ethical concerns were evaluated in the context of the code of ethics developed by the Academy of Nutrition and Dietetics (AND) that govern the work of food and nutrition professionals. Overall, there is a need to stay vigilant about the many ethical implications of producing and consuming GM foods and GMOs.

A taste of ethical consumption at a slow food festival.

This paper examines the motives and experiences of attendees at a Slow Food festival to gain an understanding of how people engage with ethical consumer projects. Slow Food is a global social movement aimed at promoting food that is regionally, ethically, and sustainably produced, and convivially consumed. The movement uses culinary tourist events, such as food festivals and farmers' markets, to promote its philosophy and attract new members. There have been no empirical studies of ethical consumption using a Slow Food event as a case study. This study uses an ethnographic approach and a framework of virtue ethics to explore the views of people attending a major Slow Food festival in the city of Melbourne, Australia. Semi-structured interviews were conducted in situ with 33 participants (19 consumers and 14 stallholders) to discover their rationales for attending the festival, and their perspectives on ethical consumption. Transcripts were coded and thematically analysed, resulting in three themes reflecting varying degrees of public virtues (altruistic motivations) and private virtues (personal wellbeing): the quest for virtuous lifestyles through ethical consumption, the importance of co-production, and the challenges of putting ethical consumer projects like Slow Food into daily practice. The findings reveal the manner in which virtue ethics affects foodways and highlights the contingent and challenging nature of practising ethical eating.

Do information, price, or morals influence ethical consumption? A natural field experiment and customer survey on the purchase of Fair Trade coffee.

We address ethical consumption using a natural field experiment on the actual purchase of Fair Trade (FT) coffee in three supermarkets in Germany. Based on a quasi-experimental before-and-after design the effects of three different treatments - information, 20% price reduction, and a moral appeal - are analyzed. Sales data cover actual ethical purchase behavior and avoid problems of social desirability. But they offer only limited insights into the motivations of individual consumers. We therefore complemented the field experiment with a customer survey that allows us to contrast observed (ethical) buying behavior with self-reported FT consumption. Results from the experiment suggest that only the price reduction had the expected positive and statistically significant effect on FT consumption.

Rationalizing meat consumption. The 4Ns.

Recent theorizing suggests that the 4Ns - that is, the belief that eating meat is natural, normal, necessary, and nice - are common rationalizations people use to defend their choice of eating meat. However, such theorizing has yet to be subjected to empirical testing. Six studies were conducted on the 4Ns. Studies 1a and 1b demonstrated that the 4N classification captures the vast majority (83%-91%) of justifications people naturally offer in defense of eating meat. In Study 2, individuals who endorsed the 4Ns tended also to objectify (dementalize) animals and included fewer animals in their circle of moral concern, and this was true independent of social dominance orientation. Subsequent studies (Studies 3-5) showed that individuals who endorsed the 4Ns tend not to be motivated by ethical concerns when making food choices, are less involved in animal-welfare advocacy, less driven to restrict animal products from their diet, less proud of their animal-product decisions, tend to endorse Speciesist attitudes, tend to consume meat and animal products more frequently, and are highly committed to eating meat. Furthermore, omnivores who strongly endorsed the 4Ns tended to experience less guilt about their animal-product decisions, highlighting the guilt-alleviating function of the 4Ns.

Development of the HELIUS food frequency questionnaires: ethnic-specific questionnaires to assess the diet of a multiethnic population in The Netherlands.

OBJECTIVES: Ethnic minorities are often not included in studies of diet and health because of a lack of validated instruments to assess their habitual diets. Given the increased ethnic diversity in many high-income countries, insight into the diets of ethnic minorities is needed for the development of nutritional policies and interventions. In this paper, we describe the development of ethnic-specific food frequency questionnaires (FFQs) to study the diets of Surinamese (African and South Asian), Turkish, Moroccan and ethnic Dutch residents of The Netherlands. METHODS: An existing Dutch FFQ was adapted and formed the basis for three new FFQs. Information on food intake was obtained from single 24 h recalls. Food items were selected according to their percentage contribution to and variance in absolute nutrient intake of the respective ethnic groups. A nutrient database for each FFQ was constructed, consisting of data from the Dutch Food Composition table; data on ethnic foods were based on new chemical analyses and available international data. RESULTS: We developed four ethnic-specific FFQs using a standardised approach that included ~200 food items each and that covered more than 90% of the intake of the main nutrients of interest. CONCLUSIONS: The developed FFQs will enable standardised and comparable assessment of the diet of five different ethnic groups and provide insight into the role of diet in differences in health between ethnic groups. The methodology described in this paper and the choices made during the development phase may be useful in developing similar FFQs in other settings.

Differences between health and ethical vegetarians. Strength of conviction, nutrition knowledge, dietary restriction, and duration of adherence.

Little research has been published concerning the differences between health oriented and ethically oriented vegetarians. The present study compared differences in conviction, nutrition knowledge, dietary restriction, and duration of adherence to vegetarianism between the two groups. Subjects completed an online survey and were grouped by original reason for becoming vegetarian (n=292, 58 health, 234 ethical), and current reason for remaining vegetarian (n=281, 49 health, 232 ethical). Whether grouped by current or original motivation, ethical vegetarians scored higher on the conviction instrument than health vegetarians and exhibited somewhat greater dietary restriction (significant when grouped by current motivation) and had been vegetarian for longer (significant when grouped by original motivation). Nutrition knowledge did not differ between the two groups. The results suggest that ethical vegetarians could experience stronger feelings of conviction and consume fewer animal products than health vegetarians, and may remain vegetarian longer. More research is necessary to understand how vegetarians' eating behaviors are influenced by their motivational profiles.

When good deeds leave a bad taste. Negative inferences from ethical food claims.

Consumer research has demonstrated halo effects arising from advertising claims on food packaging (e.g., "organic," "no cholesterol") that promote misperceiving products more positively on other dimensions (e.g., low-calorie, low-fat). However, little research has explored the conditions under which such claims might give rise to more negative rather than positive evaluations. This paper highlights two domains of judgment in which an ethical or values-based claim ("organic") can promote negative impressions. In Study 1, participants judged organic foods relative to conventional foods on healthfulness and expected taste quality. Results suggest that whereas organics are perceived as more healthful than conventional foods (consistent with previous findings), they are also perceived as less tasty, especially among participants low in environmental concern. In Study 2, participants judged the effectiveness of a formula drink intended to help alleviate malnourishment that was described as organic or not, depending on experimental condition. Results showed that participants high in environmental concern (who typically evaluate organic products positively) judged the drink more negatively (i.e., as less effective) when it was described as "organic." Discussion focuses on possible mechanisms for these effects, as well as the moderating role of judgment type and perceivers' values in halo effects more broadly.

Bioética: a ética da vida sob múltiplos olhares / Bioethics: the ethics of life in multiple views

Ao defender que o princípio de toda ética deve ser a reverência pela vida, o filósofo e humanista Albert Schweitzer descola o foco da ética tradicional, limitada ao aspecto das relações humanas, para uma posição de abrangência global que envolve todas as formas de vida, nelas incluída a própria natureza.Inspirado pelas ideias de Schweitzer e observando que o atual crescimento científico nem sempre é acompanhado em igual proporção pelo florescimento da ética na humanidade, Van Rensselaer Potter propõe, em 1971, o termo Bioética e enfatiza a necessidade premente de se procurar uma nova conduta, formada a partir de dois componentes que devem ficar inseparáveis: o conhecimento técnico-biológico e a promoção dos valores humanos.Hoje, quando é extrema a rapidez com que a ciência e a tecnologia se desenvolvem sem que haja a correspondente expansão dos processos éticos, torna-se indispensável que a Bioética passe a permear todos os outros saberes. Neste livro, olhares que se originam de múltiplas ciências confirmam a necessidade dessa presença em vários aspectos da vida cotidiana e trazem a experiência de pessoas que procuram aplicar em suas áreas de atuação a essência do pensamento bioético: a busca e o uso do conhecimento técnico-científico embasados numa conduta ética...
