My husband has gotten really in to documentaries in the last few months and we've been Primal with a vengeance for a few weeks now. In hopes of keeping our focus high, I'd like to know your favourite documentaries related to food, health, Primal living - or anything else (I fall asleep during the financial documentaries ).

I really enjoyed Fat Head when I first saw it years ago, and King Corn and Food Inc. were eye-openers.

Any other suggestions?
