Opportunities for intervention and innovation in the UK School Food System: the GENIUS (Generating Excellent Nutrition In UK Schools) network

点击翻译按钮获取中文摘要

Food provided in schools has a major influence on the quality of children's diets and has the potential to reduce inequalities in dietary intake between children according to their social or economic background. The quality of diet in childhood has been shown to impact on future development, educational achievement, health and well-being outcomes, and also influences diet in adulthood, as well as disease risk (e.g. diabetes, heart disease) in later life. There are differences in how schools arrange their food provision and what they serve, between schools and between countries in the UK, and this is not well understood. We propose a UK school food network (GENIUS), considering the food system across the preschool, primary and secondary schools, and including all school food provision, both within and outside the canteen. The aim of this network will be to work towards a more health-promoting food and nutrition system in UK schools. Objectives include the development of a network of academics and non-academics across the UK actively researching and influencing school food, the use of a range of novel research methods to understand the current UK school food system, and appreciate its complexities, and examination of similarities and differences and areas of best practice between the four nations of the UK. Finally, the network will explore opportunities for interventions that will positively impact on school food, improve the diet quality of children at school and reduce inequalities. The network will bring together researchers from a range of backgrounds including nutrition, epidemiology, public health, sensory science, health economics, health informatics, health psychology, education, planning and policy. Inclusion of project partners who are actively involved in the provision of school food from across the UK, including from local government, catering providers, pupils and parents, will make sure the work of the network is immediately useful and, together, this team of academics and non-academics will ensure the-development of research priorities and questions that are relevant in the school setting. This network will use a combination of workshops, working groups and funding of small projects to map the school food system and work together to develop research questions. Understanding the current food system and building this network of those interested in and working in school food will advance research and policy around the food environment in schools. Findings will be presented widely in both the academic and non-academic setting to make sure the findings have an impact. Funding applications will be developed based on the initial co-production of research questions and priority areas during network activities, working in partnership with policy makers and schools, and will sustain the network in the longer term.
