In France, dietary guidelines have been published since 2001 as part of the National Nutrition and Health Program (Programme national nutrition santé, PNNS). New scientific data and recent reports from the French Agency for Food, Environmental and Occupational Health and Safety (Agence nationale de sécurité sanitaire de l'alimentation, de l'environnement et du travail, ANSES) and the High Council for Public Health (Haut Conseil de santé publique, HCSP) prompted the General Directorate for Health (Direction générale de la santé, DGS) to task Santé publique France with updating dietary guidelines for all populations. The new recommendations for adults on diet, physical activity, and sedentary behavior were published in February 2019 (Delamaire et al., 2019). In September 2021, Santé publique France published its new recommendations regarding complementary foods for children up to 3 years of age, in the form of a multimedia communication campaign. Santé publique France has used a participatory approach to develop recommendations that are both clear and achievable for parents, and easy for professionals to use in their daily practice. These recommendations include two complementary components: dietary recommendations—which also cover physical activity and sedentary behavior—and advice for parents on educational strategies regarding complementary feeding and family meals. At the same time, research was conducted to determine which formats would be best suited for disseminating these messages. This resulted in the creation of a 36-page brochure and a poster for parents featuring a table of foods to introduce during the first three years of childhood. Additional resources and content were also recommended to provide parents with a range of tools tailored to their preferred media (leaflets, videos, website, menus, recipes), which together formed a comprehensive communication campaign. A document summarizing the new recommendations has also been prepared for professionals working in health and early childhood. Santé publique France was supported in this work by a committee that brought together specialists who have direct contact with the relevant populations (healthcare, maternity and children’s services, childcare), particularly the most disadvantaged, along with epidemiologists and professionals from the fields of health promotion and prevention, information and communication, and research into children’s eating behaviors. Several phases of the study were conducted in collaboration with parents, including those from low-income backgrounds, and with the pediatricians who communicate these recommendations, allowing for the wording to be approved or revised throughout the design process. Some of these studies were conducted by the Center for Taste and Feeding Behavior (Centre des sciences du goût et de l'alimentation, CSGA) at the French National Institute for Agriculture, Food and Environment (INRAe) as part of the European project Edulia, and others by Santé publique France. Santé publique France also consulted the various bodies involved in updating the recommendations—DGS, ANSES, and HCSP—to ensure that the public outreach efforts were consistent with the scientific opinions of ANSES and the HCSP. These new recommendations from Santé publique France were publicized in a communication campaign launched in the fall of 2021.
