Given the changing circumstances in the nutrition landscape, there is a need to reassess and reiterate the role of the schools in improving health and nutritional status of children.

Looking at schools as a (food system) to improve nutrition offers insights into what interventions to implement and combine to ensure the best possible nutrition outcomes for children in schools, their families and their communities, both now and in future.
