Global efforts for sustainable healthy diets include the Sustainable Development Goals by the United Nations in 2015, the Sustainable Healthy Diets by the Food and Agriculture Organization of the United Nations and the World Health Organization in 2019 and the Planetary Health Diet by the EAT-Lancet Commission. The food system is a dynamic and complex system, and systems approach is useful in providing stakeholders and policymakers with a comprehensive understanding of the broader food system. As local efforts, some of the recent articles using systems approach are introduced. They include systems modelling for local sustainability, policy activities for healthy and sustainable diets, food-related policymaking processes, low fruit and vegetable intake in children, and livestock-derived food system. In light of the existence of various stakeholders and policymakers, redesigning of the food system using systems approach may help mitigate climate change.
