Introduction
Three food chains sustain modern eaters, and each is traced from soil and sunlight to a finished meal. The first, the industrial chain, begins in the cornfields of Iowa, where George Naylor farms 470 acres for less than it costs to produce, kept afloat by government subsidies that have swollen the annual corn harvest from four billion to ten billion bushels. This surplus flows through a vanishingly small number of corporate hands (Cargill and ADM control roughly a third) into feedlots, wet mills, and processing plants. Steer number 534, purchased for $598 from a South Dakota ranch, spends his final months at Poky Feeders in Kansas, consuming thirty-two pounds of corn-based feed daily while antibiotics mask the diseases his unnatural diet causes. At the wet mill, corn is broken into hundreds of fractions: high-fructose corn syrup, ethanol, modified starches, emulsifiers. At General Mills, four pence of commodity corn becomes four pounds of branded cereal. The industrial chain ends at McDonald's, where a family's 4,510-calorie lunch is, under the mass spectrometer, almost entirely corn. The industrial eater has become "corn's koala."
