The integrated model developed here included three subsystems (producer, consumer, nutrition) and nine stages (production, processing, distribution, acquisition, preparation, consumption, digestion, transport, metabolism). The integrated model considers the processes and transformations that occur within the system and relationships between the system and other systems in the biophysical and social environments. The integrated conceptual model of the food and nutrition system presents food and nutrition activities as part of a larger context and identifies linkages among the many disciplines that deal with the food and nutrition system.

An emerging user-led participatory methodology : Mapping impact pathways of urban food system sustainability innovations
23 novembre 2021, par Mathilde COUDRAYThis chapter presents the general framework for the URBAL project as well as the main interwoven considerations and approaches that are the backbone of the methodology. Please note that this is an ongoing project and that it has evolved since the chapter has been written. We will point out some changes in the methodology as the chapter proceeds

Should we go “home” to eat ? : toward a reflexive politics of localism
3 novembre 2021, par Mathilde COUDRAY“Coming home to eat” [Nabhan, 2002. Coming Home to Eat : The Pleasures and Politics of Local Foods. Norton, New York] has become a clarion call among alternative food movement activists. Most food activist discourse makes a strong connection between the localization of food systems and the promotion of environmental sustainability and social justice. Much of the US academic literature on food systems echoes food activist rhetoric about alternative food systems as built on alternative social norms. New ways of thinking, the ethic of care, desire, realization, and vision become the explanatory factors in the creation of alternative food systems. In these norm-based explanations, the “Local” becomes the context in which this type of action works. In the European food system literature about local “value chains” and alternative food networks, localism becomes a way to maintain rural livelihoods. In both the US and European literatures on localism, the global becomes the universal logic of capitalism and the local the point of resistance to this global logic, a place where “embeddedness” can and does happen. Nevertheless, as other literatures outside of food studies show, the local is often a site of inequality and hegemonic domination. However, rather than declaim the “radical particularism” of localism, it is more productive to question an “unreflexive localism” and to forge localist alliances that pay attention to equality and social justice. The paper explores what that kind of localist politics might look like.

Ultra-processed products are becoming dominant in the global food system
26 octobre 2021, par Mathilde COUDRAYThe relationship between the global food system and the worldwide rapid increase of obesity and related diseases is not yet well understood. A reason is that the full impact of industrialized food processing on dietary patterns, including the environments of eating and drinking, remains overlooked and underestimated. Many forms of food processing are beneficial. But what is identified and defined here as ultra-processing, a type of process that has become increasingly dominant, at first in high-income countries, and now in middle-income countries, creates attractive, hyper-palatable, cheap, ready-to-consume food products that are characteristically energy-dense, fatty, sugary or salty and generally obesogenic. In this study, the scale of change in purchase and sales of ultra-processed products is examined and the context and implications are discussed. Data come from 79 high- and middle-income countries, with special attention to Canada and Brazil. Results show that ultra-processed products dominate the food supplies of high-income countries, and that their consumption is now rapidly increasing in middle-income countries. It is proposed here that the main driving force now shaping the global food system is transnational food manufacturing, retailing and fast food service corporations whose businesses are based on very profitable, heavily promoted ultra-processed products, many in snack form.

20/ Does weight status increase vulnerability to the food environment?
16 September 2022, by Mathilde COUDRAY– Marine Mas, UMR CSGA, INRAE, Dijon, France Stéphanie Chambaron, UMR CSGA, INRAE, Dijon, France Marie-Claude Brindisi, CHU Bourgogne, Dijon, France
Key points All individuals tend to “go towards” food automatically, especially food that is energy-dense. This potentially explains the obesogenic effect of the Western food environment. Some individuals have a cognitive vulnerability to the food environment. This vulnerability is driven by more than conscious factors, and challenges the “lack of (...) -
How the microbiome challenges our concept of self
26 octobre 2021, par Mathilde COUDRAYToday, the three classical biological explanations of the individual self––the immune system, the brain, the genome––are being challenged by the new field of microbiome research. Evidence shows that our resident microbes orchestrate the adaptive immune system, influence the brain, and contribute more gene functions than our own genome. The realization that humans are not individual, discrete entities but rather the outcome of ever-changing interactions with microorganisms has consequences beyond the biological disciplines. In particular, it calls into question the assumption that distinctive human traits set us apart from all other animals––and therefore also the traditional disciplinary divisions between the arts and the sciences.

Dietary diversity as a household food security indicator
3 novembre 2021, par Mathilde COUDRAYHousehold food security is an important measure of well-being. Although it may not encapsulate all dimensions of poverty, the inability of households to obtain access to enough food for an active, healthy life is surely an important component of their poverty. Accordingly, devising an appropriate measure of food security outcomes is useful in order to identify the food insecure, assess the severity of their food shortfall, characterize the nature of their insecurity (for example, seasonal versus chronic), predict who is most at risk of future hunger, monitor changes in circumstances, and assess the impact of interventions. However, obtaining detailed data on food security status—such as 24- hour recall data on caloric intakes—can be time consuming and expensive and require a high level of technical skill both in data collection and analysis. This paper examines whether an alternative indicator, dietary diversity, defined as the number of unique foods consumed over a given period of time, provides information on household food security. It draws on data from 10 countries (India, the Philippines, Mozambique, Mexico, Bangladesh, Egypt, Mali, Malawi, Ghana, and Kenya) that encompass both poor and middle-income countries, rural and urban sectors, data collected in different seasons, and data on calories acquisition obtained using two different methods. ....[D]ietary diversity would appear to show promise as a means of measuring food security and monitoring changes and impact, particularly when resources available for such measurement are scarce.
