The Opticourses project aims to improve the nutritional quality/price (NQP) ratio of the food purchases of people claiming to be facing financial problems. Following one of the main principles of the French National Nutrition and Health Program (PNNS), the project starts from the principle that to modify food consumption favourably and durably, one must act on both the demand and the supply (see figure). The "demand" part of the project is based on participatory workshops, and the "supply" part relies on intervention of social marketing in shops.
