Des savoirs sans effet : l'espace controversé de la nutrition

Abstract : This dissertation studies the development of a Public Health policy in nutrition in France. Based on interviews, ethnographic observations and archives, it approaches 1) the elaboration and the uses of instruments close to the actors who conceive and implement them; 2) controversies around food marketing regulation; 3) the emergence and diffusion of behavioral sciences (social marketing, nudge and neurosciences). At the crossroad of public policy analysis, sociology of expertise and organizational studies, I show that the development of a Public Health Program on nutrition called “Programme National Nutrition Santé” (PNNS) does not succeed in stabilizing a definition, even contested, of the problem of nutrition. The analysis of Public Health instruments reflects two main tensions. Public actors try to promote healthy eating without contesting food market and targeting individuals without stigmatizing them. At the end of the 2000s, other actors promoted “new” disciplines to change behavior in nutrition: social marketing, nudge and neuroscience. However, despite a great deal of political discourse and enthusiastic expertise, this knowledge has not been translated into public action. I show that both public and private actors (communication agencies and food industries) and scientists have a strategic use of behavioral knowledge: in order to legitimate a Public Health agency and academic fields or, at the opposite, contest a public policy in nutrition.
