For years I was happy enough to believe, thanks to 2nd grade science class and John Lennon, that “we are all water.” Then folks like Michael Pollan and Eric Shlosser showed us that “we are all corn.” (I have another theory that involves water, corn and fermentation, called “I am all bourbon,” but I’ll explain that one another day.)

If we are all corn, then Curt Ellis, one of the brains behind the new documentary King Corn, is in for one hell of a month. Last Thursday he announced that he will not eat foods made with corn for a month. He makes only one exception: fresh corn-on-the-cob.

“That means no corn-fed hamburgers,” Ellis writes. “No corn-sweetened juice. No corn-oiled salad dressings. Not even my beloved mono- and diglycerides! Frankly, I’m not sure if I can do it.”

I’m not sure either, but not because I think Ellis lacks the willpower. I just think corn will find a way in. It always does.
