Promoting Healthy and Environmentally Sustainable Diets

Another line of our work sits at the intersection of nutrition and sustainability, where we seek to identify dietary “win-wins” – food choices that promote health while minimizing environmental harms. We have used nationally representative dietary intake data to show that simple, actionable dietary changes – like replacing a beef burrito with a chicken burrito – can add up to yield major benefits to both health outcomes and environmental sustainability. Our ongoing work uses mixed methods and randomized trials to design and evaluate scalable strategies for encouraging consumers to adopt these changes.
