King Corn, The Documentary

Awesome! If you have the chance to get or borrow the DVD, it's worth the watch. See the trailer here. It's all about how we are made of corn - literally! One of the "stars" of the movie has a hair analysis done and the carbon in his body is derived mostly from corn. He had corn hair. And the corn comes from corn by-products in over 60% of our food. Either as preservatives, sweeteners, or flavor enhancers of some sort. The movie is funny, educational, and of course, thought-provoking about what you put in your mouth.
