Welcome to the Stanford Food Policy Lab
Our Vision
The foods we eat have major implications for both human health and environmental sustainability. We envision a world where healthy, sustainable foods are an attractive, affordable, and accessible choice for all.
Our Mission
Our mission is to design and evaluate policies and interventions that improve diet, promote environmental sustainability, and advance health equity.
Our Approach
We work with policymakers, advocates, and other changemakers throughout our research process to ensure we are asking and answering the research questions that key stakeholders most need addressed.

Sugary Drink Taxes and Pricing Policies
We use quasi-experiments and simulation modeling to study whether taxes and other pricing policies improve health.

Alcohol Warning Labels
We examine how alcohol marketing affects consumers and whether improved warning labels can increase awareness and reduce unhealthy drinking.
