Eating can be one dangerous business. Don’t take another bite till you see Robert Kenner’s Food, Inc., an essential, indelible documentary that is scarier than anything in the last five Saw horror shows. Decepticons have nothing on ears of corn when it comes to transforming into mutant killers. Kenner keeps his film bouncing with humor, music and graphics. Just like the ads that shove junk food down our faces. The message he’s delivering with the help of nutrition activists, including Eric Schlosser (Fast Food Nation) and Michael Pollan (The Omnivore’s Dilemma), is an eye-opener. High-fructose corn syrup and its friend the E.coli virus are declaring war on national health, and federal agencies, lobbied by Big Agriculture, ain’t doing a thing to stop it. Reason? Profits. The movie offers solid alternatives. If the way to an audience’s heart is through its stomach, Food, Inc. is a movie you’re going to love.
