[Editorial] Dietary schooling

Food systems represent a key intervention point to improve human health, environmental sustainability, and resilience to climate change. We have increasingly clear evidence of the dietary characteristics and associated agricultural production systems that have the most potential to improve nutrition while reducing environmental harms and maximising food system resilience. However, practical changes aligned with this science-based evidence remain challenging, indeed increases in childhood obesity and diabetes and the targeting of children by junk food producers are particularly concerning trends.
