Summary

This updated analysis builds upon the 2019 EAT–Lancet Commission, expanding its scope and strengthening its evidence base. The first Commission defined food group ranges for a healthy diet and identified the food systems' share of planetary boundaries. In this Commission, we add an analysis of the social foundations for a just food system, and incorporate new data and perspectives on distributive, representational, and recognitional justice, providing a global overview on equity in food systems. Substantial improvements in modelling capacity and data analysis allow for the use of a multimodel ensemble to project potential outcomes of a transition to healthy and sustainable food systems.
