In France, dietary guidelines have been published since 2001 as part of the National Nutrition and Health Program (PNNS). Following developments in scientific data and recent reports from the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) and the High Council for Public Health (HCSP), the Directorate General for Health (DGS) tasked Santé publique France with updating dietary guidelines for all population groups. The new recommendations regarding diet, physical activity, and sedentary behavior for adults were published in February 2019 (Delamaire et al., 2019). In September 2021, Santé publique France published its new recommendations for children under the age of 3, presented across various media as part of a communication campaign. Santé publique France implemented a participatory approach to develop recommendations that are understandable and acceptable to parents and easily applicable by professionals in their practice. These recommendations fall into two complementary categories: recommendations on diet—as well as on physical activity and sedentary behavior—and advice on educational strategies for parents to help them support their children in discovering foods and then joining the family table.At the same time, the most suitable types of informational materials for disseminating these messages were studied. This led to the creation of a 36-page brochure and a small poster for parents featuring a chart introducing foods up to the child’s third birthday. Additional materials and content were also recommended to offer parents a range of tools tailored to their information-seeking habits (leaflets, videos, website, menus, recipes) and thus develop a comprehensive communication strategy. A document summarizing the new recommendations was also developed for healthcare and early childhood professionals. Santé publique France drew on a thematic committee comprising early childhood professionals (health, maternal and child health services, and daycare centers) in direct contact with the affected populations, particularly those with lower incomes, as well as professionals in epidemiology, health prevention and promotion, information and communication, and research on children’s eating behaviors. Various phases of studies involving parents—including those from so-called low-income groups—as well as pediatricians who communicate these recommendations, helped refine or validate the wording choices throughout the design process. Several studies were conducted by the Center for Taste and Food Sciences (CSGA) at INRAe as part of the Edulia project, and others were carried out by Santé publique France. Santé publique France also consulted the various bodies involved in updating the recommendations—the Directorate General for Health (DGS), ANSES, and the High Council for Public Health (HCSP)—to ensure that the public outreach efforts aligned with the scientific foundations of the ANSES and HCSP opinions. These new recommendations from Santé publique France were the subject of a communication campaign in the fall of 2021.
