Daphne Miller is an family physician who practices integrative medicine and an associate professor in the Department of Family Medicine at the Univeristy of California. Her most recent book is "Farmocology: What Innovative Family Farming Can Teach Us about Health and Healing." It shows how lessons from sustainable farming can be applied to medical practice. And we talk with Brian Snyder, the head of the Pennsylvania Association for Sustainable Agriculture, about recent changes to food safety laws and what those changes mean to the small-scale farmers he represents.
