The full picture of people's realities must be considered to deliver better diets for all.

Efforts to address poor-quality diets have stepped up considerably in recent years, but the problem of inadequate, unhealthy, unsustainable and unequal diets persists. Here we argue that to get policies and interventions working more effectively and equitably, a fresh approach is needed-one that considers the full picture of people's realities. People's realities interact to shape the way people respond to and engage with policies and interventions, thereby influencing their impact, particularly, albeit not only, on dietary inequalities. We propose a tool that brings together key realities that shape impact, including the material, economic and psychosocial realities that people face in their households, families, food environments, social interactions and cultures. The purpose of the tool is to help policymakers, intervention practitioners and researchers committed to improving diets achieve greater success by helping them think through the full picture of people's realities when identifying, designing, implementing and evaluating policies and interventions.
