Heya,
This
should probably be posted in a regional forum, but I just found this great CBC doc with Michael Pollen talking about his research on healthy eating. Its pretty great! Unfortunately its only viewable in Canada for now. Maybe it broadcasts on another network in the US?
The series is called 'The Passionate Eye', a long running documentary series produced by the CBC. The title of the Documentary 'In Defense of Food'. Not sure if CBC produced this episode or just co produced it.
enjoy!
