The recent sharp increase of sensitivity towards environmental issues arising from plastic packaging has boosted interest towards alternative sustainable packaging materials. This new trend promotes the industrial exploitation of knowledge on chitosan-based films. Chitosan has been extensively investigated and used due to its unique biological and functional properties. However, inherent drawbacks including low mechanical properties and high sensitivity to humidity represent major limitations to its industrial applications, including food packaging.
Transforming food systems is essential to ensuring nutritious, safe, affordable, and sustainable diets for all, including children and adolescents. This paper proposes a new conceptual framework (the ‘Innocenti Framework’) to better articulate how the diets of children and adolescents are shaped by food systems.
Building on the Innocenti Framework on Food Systems for Children and Adolescents, this paper describes the significance of a food systems approach to improving children's diets. It summarizes the key learnings on effective intervention design from the papers in this special issue, focusing on the determinants in the framework: food supply chains, food environments, and behaviors of caregivers, children and adolescents. It lays out relevant policy and programmatic implications and organizes these according to the Nuffield ladder of public policy interventions.
