Abstract
Food systems are priority levers for resolving nutritional, health and environmental issues. Using an epidemiological approach, the Nutritional Epidemiology Research Team has developed the multidisciplinary BioNutriNet project (biology, toxicology, economics, epidemiology, agronomy), which aims to characterize the sustainability of the more or less organic diets of participants in the NutriNet-Santé cohort study. This project has built up a large database of over 30, ,000 individuals, which can now be used to answer many questions on the links between diet, environment and health, taking into account individual profiles. Descriptive, etiological and optimization work is being carried out to propose action levers for public health purposes, and to provide quantified and documented elements for public policies (Ministry of Ecological Transition, ADEME, etc.).
