January's Men's Journal magazine serves up some definite corny news, informing readers that in the same way Morgan Spurlock opened our eyes with his documentary Super Size Me, Ian Cheney and Curt Ellis take us to the cornfields of Iowa to school us on our strange and unhealthy dependence on corn.

Directed by a guy named Aaron Wolf, the new documentary King Corn will apparently convince us that nearly everything we eat is corn. Our livestock feeds on it, our soda is sweetened by it, our food is deep-fried in it, and even the medication NyQuil contains it. Why is this newsworthy? Because corn is likely the root cause of America's obesity epidemic.

Cheney and Ellis, both 24, don't just passively study and report on this whole corn issue. They live it. Leaving their suburban Boston homes, the pair spends a year growing their very own acre of corn. The first thing they learn: It's a cheap and nutritionless kernel that dominates America's corn belt and thus, everything we put in our bodies. They tell us that we overproduce corn, force feed it to our cows instead of allowing them to graze, and make high-fructose corn syrup in crazy quantities. They also interview a New York cab driver suffering from Type II diabetes, a man who happened to drop 100 pounds by giving up corn-sweetened soda.

"This documentary is enough to leave you distrustful of everything on your plate," says the Boston Globe. For a sneak peek at the movie that will challenge your trust, take a peek at the King Corn trailer, located right here.
