The film examines corporate farming in the United States, concluding that agribusiness produces food that is unhealthy, in a way that is environmentally harmful and abusive of both animals and employees.

n Food, Inc., filmmaker Robert Kenner lifts the veil on America's food industry, exposing the highly mechanized underbelly that has been hidden from the American consumer with the consent of government's regulatory agencies, USDA and FDA. The nation's food supply is now controlled by a handful of corporations that often put profit ahead of consumer health, the livelihood of the American farmer, the safety of workers and our own environment. There's bigger-breasted chickens, the perfect pork chop, herbicide-resistant soybean seeds, even tomatoes that won't go bad, but there's also new strains of E. coli the harmful bacteria that causes illness for an estimated 73,000 Americans annually. America is riddled with widespread obesity, particularly among children, and an epidemic level of diabetes among adults.

Featuring interviews with such experts as Eric Schlosser (Fast Food Nation), Michael Pollan (The Omnivore's Dilemma, In Defense of Food: An Eater's Manifesto) along with forward thinking social entrepreneurs like Stonyfield's Gary Hirshberg and Polyface Farms' Joel Salatin, Food, Inc. reveals surprising and often shocking truths about what Americans eat, how it's produced, who the country has become as a nation and where it is going from here.
