How can we help the planet by rethinking our diets? In a new book, Can Fixing Dinner Fix the Planet?, Dr. Jessica Fanzo, a Bloomberg Distinguished Professor of Global Food Policy and Ethics points out how our food options are often unhealthy for human bodies—and for the planet. Dr. Fanzo talks with Dr. Josh Sharfstein about making changes at both policy and individual levels, from the responsible use of genetically modified organisms to redesigning “choice architecture” in grocery stores and restaurants.
