I just found this great podcast of an April, 2006 National Public Radio (NPR) interview with Omnivore's Dilemma author, Michael Pollan:
Author Michael Pollan: 'The Omnivore's Dilemma'
available at http://www.npr.org/templates/story/story.php?storyId=5342514
The Science Friday segment is a great encapsulation of all the fascinating spins this wonderfully insightful author has on human eating habits and the developing distortions of food choices, much magnified by the food manufacturing industry.
One of my favorite comments from Pollan: "The USDA should be called "The Department of Corn," referring to the ubiquitous dissemination of corn products into livestock and human foods that has increasingly led to the enormous health problems we're all facing in 2007.
