To find the path to long life and health, Dan Buettner and his team study the world’s “Blue Zones,” communities whose elders live with vim and vigor to record-setting age. In this episode, Buettner debunks the most common nutrition myths and offers a science-backed blueprint that outlines how the average American can live another 12 quality years. What are the diet and lifestyle habits that keep people spry past age 100? What should you be eating to live a longer life? Buettner is in conversation with Ezekiel Emanuel, chair of the Department of Medical Ethics and Health Policy at the University of Pennsylvania.
