Food Health Policies and Ethics: Lay Perspectives on Functional Foods

Functional foods are a challenge tofood health policies, since they questioncentral ideas in the way that food healthpolicies have been developed over the lastdecades. Driven by market actors instead ofpublic authorities and focusing on the role ofsingle foods and single constituents in foodsfor health, they contrast traditional wisdombehind nutrition policies that emphasize therole of the diet as a whole for health.Sociological literature about food in everydaylife shows that technical rationality co-existswith other food related rationalities, such aspractical and economic rationalities, socialand relational rationalities, and symbolicrationalities that influence citizens' ordinaryeating habits. An examination of lay views onexpert knowledge about food and health showthat skepticism exists with respect to thebasis of and balance of expert advice. Critical points with respect to how functionalfoods may influence routines in the populationswith relevance for public health include thefact, that they promote a way of thinking offood and health that is in conflict withwell-established practical ways of ensuring abalanced diet.     

Leveraging foodways for health and justice

ABSTRACT

The global industrial food system is increasingly recognised as a source of poor health that deepens social and economic inequity. Health advocates, policy makers, and food activists strive to improve nutrition and food access across racial and ethnic divides; however, given established approaches, they may miss fundamental pathways for improving health and justice comprehensively. While food access and nutrition are often identified as primary concerns for marginalised communities and the reason for food insecurity and food-related illness, critical food justice scholars use a more expansive lens to suggest a democratised food system is needed, and that solutions based solely in access to healthy food can undermine more systemic approaches. Our research extends this analysis, highlighting the importance of endemic food culture (foodways) as a tool for retaining identity, building community, and maintaining health among refugee populations in one community in Salt Lake City, Utah. Further, this work suggests that community engagement and expertise is essential in leveraging foodways such that marginalised communities can effectively resist cheap, unhealthy, and placeless calories.     

Food Law,Ethics, and Food Safety Regulation: Roles,Justifications, and Expected Limits

Recent food emergencies throughout the world have raised some serious ethical and legal concerns for nations and health organizations. While the legal regulations addressing food risks and foodborne illnesses are considerably varied and variously effective, less is known about the ethical treatment of the subject. The purpose of this article is to discuss the roles, justifications, and limits of ethics of food safety as part of public health ethics and to argue for the development of this timely and emergent field of ethics. The article is divided into three parts. After a short introduction on public health ethics, all levels of food safety processes are described and the role that ethics play in each of these levels is then analyzed. In the second part, different models describing the function of food law are examined. The relationship between these models and the role of ethics of food safety is assessed and discussed in the final part, leading to some relevant comments on the limits of the role and effect of ethics of food safety.     

Trust,Food, and Health. Questions of Trust at the Interface between Food and Health

The food sector and health sector become more and more intertwined. This raises many possibilities, but also questions. One of them is the question of what the implication is for public trust in food and health issues. In this article, I argue that the products on the interface between food and health entails some serious questions of trust. Trust in food products and medical products is often based upon a long history of rather clear patterns of mutual expectations, yet these expectations are not similar in both sectors. As long as the food sector and health sector remain distinct, these differences will not lead to problems of trust, yet when new products are introduced, like functional foods or personalized dietary advices, trust can be threatened. To prevent this, we need clarity with regard to what we can expect of these new products and of whom to expect what in this situation. This requires not␣only adequate information on operating procedures, but also a profound debate␣on responsibilities and the explication and interpretation of moral values and norms.     

Local food networks as catalysts for food policy change to improve health and build the economy

Local food networks (LFNs) are growing in popularity, in part as a response to broader criticisms of conventional food production. Municipal policy-makers have the opportunity to work with stakeholders to build LFNs to increase access to healthy foods in cities and ultimately improve population health and well-being. Building opportunities for healthy eating is particularly important in our study area. Flint, Michigan, is a post-industrial shrinking city suffering from the economic and health effects of deindustrialisation. Various stakeholders in Flint have responded to a significant issue with access to food by strengthening collaborations through a food policy council (FPC). Growth in the local food system has been supported by administrators and community advocates alike, through supporting community gardens, farmers' markets, and urban agriculture in a manner similar to nearby Detroit. Participant observation was conducted with stakeholders involved in the development of the LFN and the FPC in Flint. Stakeholders were exposed to existing research on the food system to help inform their policy direction. The group expressed several core concerns and prospects for future work, including a strong emphasis on consensus-based decision-making. Based on the synthesis of stakeholder opinions, policy recommendations are made to aid in continued planning of the LFN. Planning for food is an important first step in improving public health and strengthening local economic development in post-industrial cities. This research highlights the issue by making explicit the challenges and opportunities for policy advocacy in LFNs.     

The Ethical Values in the U.S. Agricultural and Food System

Many segments of society have systems of values arising from collective beliefs and motivations. For agriculture, and our food system, increasing production to feed the growing human population clearly is a core value. However, a survey we conducted, together with a previously reported survey, showed that the curricula of most U.S. colleges of agriculture do not offer ethics courses that examine the basis of this core value or include discussion of agriculture’s ethical dilemmas such as misuse of pesticides, not progressing rapidly enough toward sustainability goals, relative lack of involvement in addressing diet-related health issues, and lack of commitment to reducing agriculture’s role as a contributor to global climate change. These surveys provide strong evidence that few students have an opportunity to learn ethical concepts and apply them to issues of importance to the agriculture/food system. We suggest that such issues are both growing societal concerns and serious ethical problems that demand attention if our agricultural/food system is not see its relationship with the public further imperiled. Further, we suggest that there is a need for, indeed an obligation of, the faculty of colleges of agriculture to embrace a thorough analysis and discussion of agriculture’s values and their ethical foundation. We offer our thoughts on why curricula of colleges of agriculture do not provide such opportunities and on the importance of agricultural faculties providing leadership in ethical analysis and discussion.     

What Food is “Good” for You? Toward a Pragmatic Consideration of Multiple Values Domains

What makes a food good, for you? With respect to food, the expression “good for you” usually refers to the effect of the food on the nutritional health of the eater, but it can also pertain more broadly. The expression is often used by a person who is concerned with another person’s well-being, as part of an exhortation. But when framed as a question and addressed to you, as an individual, the question can require a response, calling for accountability beyond the realm of nutrition or other material qualities of the food. Economic value may be considered as a ratio: goodness/price. In this paper, we examine the numerator, exploring a broad range of values domains related to food, attempting to obtain a more comprehensive understanding of the meaning of goodness of food. We present a typology of values domains with respect to food, divided into three main categories: (1) material considerations, (2) psychological, psychosocial, and spiritual health, and (3) the well-being of society. This understanding that results from comprehensive consideration of these values domains has important implications for an individual for use in considering the question “what food is good for you?” in order to guide his or her future actions, helping to distinguish between what Dewey termed immediate good and reasonable good. A pragmatic approach to a fuller consideration of food-related values domains by individuals also has broad social, political, and economic implications. If, according to the FAO, food security involves both needs and preferences, consideration of what preferences are appropriate is fundamental to achieving food security. The questions about what is considered to be good food are central to questions about the sorts of food and agricultural systems human societies will seek to sustain. The approach to resolving this important aspect of sustainability might help inform a more general question as to appropriate limitations on preferences, a question fundamental to achieving sustainability in general.     

Food Supply Chain Governance And Public Health Externalities: Upstream Policy Interventions And The UK State

Contemporary food supply chains are generating externalities with high economic and social costs, notably in public health terms through the rise in diet-related non-communicable disease. The UK State is developing policy strategies to tackle these public health problems alongside intergovernmental responses. However, the governance of food supply chains is conducted by, and across, both private and public spheres and within a multilevel framework. The realities of contemporary food governance are that private interests are key drivers of food supply chains and have institutionalized a great deal of standards-setting and quality, notably from their locations in the downstream and midstream sectors. The UK State is designing some downstream and some midstream interventions to ameliorate the public health impacts of current food consumption patterns in England. The UK State has not addressed upstream interventions towards public health diet at the primary food production and processing stages, although traditionally it has shaped agricultural policy. Within the realities of contemporary multilevel governance, the UK State must act within the contexts set by the international regimes of the Common Agricultural Policy and the World Trade Organization agreements, notably on agriculture. The potential for further upstream agricultural policy reform is considered as part of a wider policy approach to address the public health externalities issuing from contemporary food supply chains within this multilevel governance context.
