Reframing Eating: Drivers, Influences, Environment, and Transitions (ReDIET) for a sustainable food system

Accelerating sustainability transitions in food systems and meeting climate change mitigation targets require fundamental changes in both production and consumption. Because research often focuses on either systemic or individual interventions, these approaches tend to fall short when used in isolation. System-level measures may overlook behavioral dynamics, while individual-focused interventions rarely scale to broader transformation. We introduce the ReDIET framework, a conceptual tool that makes explicit the interactions between system-level and individual-level drivers of sustainable dietary behavior. Drawing on insights from the natural and social sciences, the framework maps key push and pull factors and highlights how they relate across levels by integrating behavioral science with food system transition theory. ReDIET helps reveal how factors may reinforce or counteract each other. By making these relationships visible, it supports a more nuanced understanding of where interventions could be most effective in advancing sustainable food system transitions.
