Recent efforts to understand how food systems affect planetary health are both timely and essential, and have already produced important scientific insights1,2. At the same time, as the number of published food system analyses grow, there are some emerging framings that would benefit from greater conceptual clarity to ensure that insights are interpreted consistently and applied effectively across research and policy.
