If you haven't seen the documentary yet, or wouldn't mind seeing it again, the movie is available on YouTube: http://www.youtube.com/watch?v=d7Tv_mihMBA&feature=mkt-ha-drt

By any chance you're not familiar with the movie, here is the description provided:

"Filmmaker Morgan Spurlock makes himself a test subject in this documentary about the commercial food industry. Rigorously eating a diet of McDonald's fast food three times a day for a month straight, Spurlock is out to prove the physical and mental effects of consuming fast food. Spurlock also provides a look at the food culture in America through its schools, corporations, and politics as seen through the eyes of both ordinary citizens and health advocates."
