<< Background >>Childhood obesity and overweight are inevitable contemporary problems. The evolution of children's diets over the last decades, coupled with an ever-lower energy expenditure, especially during the COVID-19 period, forces us to question the development and/or reinforcement of food education for children. In southern European countries this issue has a significant impact on the health and well-being of children. In this context, the EFFECT project aims to develop food education for primary school children in France, Greece and the USA. The uniqueness of the project lies in the fact that the EFFECT project will develop training content for the children's trainers, considering that only the training of the children's ecosystem will allow the establishment of sustainable habits.<< Objectives >>The main goals of the EFFECT project are to i) propose a thorough analysis of best practices in food education toward children across Europe, to ii) improve the trainer’s awareness and knowledge on food education through dedicated pedagogical material and training sessions, to iii) create and implement the Sustainable Lifestyle Fest in all participating countries, iv) to develop food education for children at the European level through dissemination and transferability activities. It’s envisioned impacts are i) an increase of the knowledge of best practices in food education towards children across Europe, ii) an increase of pedagogical resources and tools available to support trainers in the development of food education sessions towards children, iii) an increase of the children’s knowledge regarding food products, iv) a wider dissemination and uptake of the knowledge in EU educative communities via tailored content on an e-learning platform.<< Implementation >>Different activities will be implemented in the framework of the project: whereas the WP1 will be focused on the gathering of best practices in food education towards children and analysis of needs and requirements, WP2 will aim to create dedicated pedagogical material on food education towards children for trainers. This pedagogical material will be available on an e-learning platform created during WP3 of the project, and be used for both self-learning and blended learning, as trainer’s training sessions and food education sessions towards children will be implemented as part of WP4. For these training pilot experimentations, a toolkit on training trainers will be created. Finally, an innovative concept, the Sustainable Lifestyle Fest, will be implemented in several schools and extracurricular centres in the participating countries: this activity will give children a holistic approach of food (better knowledge of food products, of issues such as food waste, reappropriation of eating habits through the design of one's own menu…), and offer their trainers ideas and advices to implement regular physical activities depending of various contexts. Activities of communication and transferability are planned to increase the visibility of the project and to exploit its results to the fullest.<< Results >>The project has 5 main project’s results: -A White Book on the best practices in food education towards children-Dedicated pedagogical material on food education towards children for trainers-Online e-learning platform with adapted pedagogical content-Toolkit on training trainers in food education towards children-Creation, implementation and transferability of the Sustainable Lifestyle Fest The project’s partners expect to train 120 - 150 European trainers, and to reach another 300 trainers through dissemination and communication activities. More than 1 000 children and 1 000 families will be reached by the project. At a local and regional levels, the project will lead to an increase of pedagogical resources available to the trainers, and thus to better informed children, families and local stakeholders. At the schools level, this project will lead to a development of food education initiatives, notably with the adaptation of the Sustainable Lifestyle Fest. In the long term, the programme is expected to have an impact on the culinary habits of the children and families. At the national and European levels, this programme and its dissemination strategy is expected to raise awareness on the food education of children, and to improve knowledge on pedagogical practices and tools regarding food education. The project will improve EU trainers' knowledge on pedagogical practices in food education, which will empower them in the development of new, related initiatives by highlighting successful practices and providing key knowledge and skills for proper implementation.
