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.

Food swamps predict obesity rates better than food deserts in the United States
3 novembre 2021, par Mathilde COUDRAYThis paper investigates the effect of food environments, characterized as food swamps, on adult obesity rates. Food swamps have been described as areas with a high-density of establishments selling high-calorie fast food and junk food, relative to healthier food options. This study examines multiple ways of categorizing food environments as food swamps and food deserts, including alternate versions of the Retail Food Environment Index. We merged food outlet, sociodemographic and obesity data from the United States Department of Agriculture (USDA) Food Environment Atlas, the American Community Survey, and a commercial street reference dataset. We employed an instrumental variables (IV) strategy to correct for the endogeneity of food environments (i.e., that individuals self-select into neighborhoods and may consider food availability in their decision). Our results suggest that the presence of a food swamp is a stronger predictor of obesity rates than the absence of full-service grocery stores. We found, even after controlling for food desert effects, food swamps have a positive, statistically significant effect on adult obesity rates. All three food swamp measures indicated the same positive association, but reflected different magnitudes of the food swamp effect on rates of adult obesity (p values ranged from 0.00 to 0.16). Our adjustment for reverse causality, using an IV approach, revealed a stronger effect of food swamps than would have been obtained by naïve ordinary least squares (OLS) estimates. The food swamp effect was stronger in counties with greater income inequality (p < 0.05) and where residents are less mobile (p < 0.01). Based on these findings, local government policies such as zoning laws simultaneously restricting access to unhealthy food outlets and incentivizing healthy food retailers to locate in underserved neighborhoods warrant consideration as strategies to increase health equity.

L’alimentation au cœur des sociabilités ville-campagne. L’exemple des marchés fermiers comme formes d’interactions entre populations agricoles et touristiques
26 octobre 2021, par Mathilde COUDRAYL’expérience alimentaire associée au tourisme semble être le lieu de multiples aspirations et représentations, notamment en espace rural, donnant lieu à de nouvelles pratiques, offres et filières situées parfois en marge d’un développement touristique plus institutionnalisé. C’est le cas de l’agritourisme, défini comme l’ensemble des activités touristiques pratiquées sur une exploitation agricole et présenté comme moyen de diversification aux bénéfices multiples. Considérant le décalage entre perceptions du monde agricole et réalité du terrain, l’agritourisme, à travers la valorisation de produits agricoles et alimentaires, est analysé comme un moyen de renouer le dialogue et de tisser des liens entre population agricole et société civile. En encourageant un public de non-initiés à réfléchir et à penser l’agriculture, en valorisant des images et des pratiques spécifiques, mais aussi en partageant des valeurs et des visions contrastées du monde agricole et rural, les agriculteurs, à travers la valorisation de leurs produits agricoles et alimentaires, sont au cœur de processus d’interactions. Cette contribution vise ainsi, avec l’exemple des marchés fermiers, à questionner l’alimentation comme vecteur de nouvelles formes de sociabilités entre ville et campagne. L’analyse se base sur une étude exploratoire conduite en 2015 dans la région Midi-Pyrénées (France) auprès d’agriculteurs et d’agricultrices proposant des marchés sur leur exploitation agricole.

The global distribution of acute unintentional pesticide poisoning : estimations based on a systematic review
26 octobre 2021, par Mathilde COUDRAYHuman poisoning by pesticides has long been seen as a severe public health problem. As early as 1990, a task force of the World Health Organization (WHO) estimated that about one million unintentional pesticide poisonings occur annually, leading to approximately 20,000 deaths. Thirty years on there is no up-to-date picture of global pesticide poisoning despite an increase in global pesticide use. Our aim was to systematically review the prevalence of unintentional, acute pesticide poisoning (UAPP), and to estimate the annual global number of UAPP.
We carried out a systematic review of the scientific literature published between 2006 and 2018, supplemented by mortality data from WHO. We extracted data from 157 publications and the WHO cause-of-death database, then performed country-wise synopses, and arrived at annual numbers of national UAPP. World-wide UAPP was estimated based on national figures and population data for regions defined by the Food and Agriculture Organization (FAO). -
The new nutrition science project
27 octobre 2021, par Mathilde COUDRAYTo show that nutrition science, with its application to food and nutrition policy, now needs a new conceptual framework. This will incorporate nutrition in its current definition as principally a biological science, now including nutritional aspects of genomics. It will also create new governing and guiding principles ; specify a new definition ; and add social and environmental dimensions and domains.

Urban governance for food security : the alternative food system in Belo Horizonte
23 novembre 2021, par Mathilde COUDRAYWith a population of 2.5 million people, the city of Belo Horizonte, Brazil, is a world pioneer in tackling food consumption, distribution and production as components of an integrated urban policy for food security. The paper gives a description of the main programmes and features of this policy arguing that over 15 years the city and its Municipal Secretariat for Food Policy and Supply have built a particular alternative food system. Marked by the comprehensive scope of its programmes ; its urban/rural focus ; the flexibility of the initiatives and, above all, by its commitment to social justice and equitable access to food, Belo Horizonte has developed a distinct mode of governance for food security. The unique ‘alterity’ of this food system is set further apart from those being attempted in Europe and in North America because it is government-driven. The paper discusses its strengths and current challenges.

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.

Malaysian Food Barometer (MFB) : a study of the impact of compressed modernisation on food habits
3 novembre 2021, par Mathilde COUDRAYThe Malaysian society is undergoing rapid modernisation. The
emerging middle class in Malaysia is influencing the lifestyles and traditional food habits of the main three ethnics (i.e. Malays, Chinese, and Indians). This article studied the impact of compressed modernisation on food in a multicultural context. The Malaysian Food Barometer (MFB), published in the year 2014, focuses on the socio-cultural determinants of food habits in Malaysia. -
Gouverner la qualité alimentaire par les applications
3 novembre 2021, par Mathilde COUDRAYL’actualité du marché des produits de grande consommation est marquée par l’apparition d’applications mobiles permettant aux consommateurs d’évaluer les produits alimentaires en scannant leurs codes-barres. Cet article analyse les critères de qualification et de notation des produits mobilisés par ces applications et les projets controversés de gouvernement des conduites qui les sous-tendent. Il montre que les applications évaluent les produits à partir de conceptions plurielles du « bien manger », qu’elles s’articulent autour de quelques dimensions prépondérantes (la qualité nutritionnelle, les additifs et le niveau de transformation des produits) et qu’elles participent tout à la fois à prolonger et à détourner l’action des pouvoirs publics en matière de gouvernement des conduites alimentaires et d’information du consommateur.

Approche sociologique des néophobies alimentaires chez l’enfant
26 octobre 2021, par Mathilde COUDRAYÀ partir d’une interrogation sur les enfants autistes, leurs singularités alimentaires ainsi que les difficultés et les ajustements pour l’entourage nourricier autour des repas, les auteurs, sociologues, questionnent les évolutions du répertoire alimentaire et plus particulièrement la phase de la néophobie. Ce travail examine la simultanéité et la complémentarité des processus de socialisation et d’individuation dans les évolutions des pratiques alimentaires des enfants. S’interroger en articulant les approches psychologique et sociologique permet d’explorer les soubassements des normes. Et aussi de distinguer la perspective phylogénétique à tendance universalisante de la néophobie de l’enfant dans le cadre de l’ontogénèse.
