Fake food and the obesity crisis

How much of our nation’s obesity crisis is driven by an overabundance of processed food — and a lack of access to the real stuff?

In a new video series co-produced by TEDMED and Fenton Studios, and filmed at TEDMED 2012, Tracie McMillan, author of “The American Way of Eating” and David Ludwig of Boston Children’s Hospital sat down with Lisa Witter to discuss the issue.
