If you are what you eat, and especially if you eat industrial food, as 99 percent of Americans do, what you are is "corn."
During the last year I've been following a bushel of corn through the industrial food system. What I keep finding in case after case, if you follow the food back to the farm — if you follow the nutrients, if you follow the carbon — you end up in a corn field in Iowa, over and over and over again.
Take a typical fast food meal. Corn is the sweetener in the soda. It's in the corn-fed beef Big Mac patty, and in the high-fructose syrup in the bun, and in the secret sauce. Slim Jims are full of corn syrup, dextrose, cornstarch, and a great many additives. The “four different fuels” in a Lunchables meal, are all essentially corn-based. The chicken nugget—including feed for the chicken, fillers, binders, coating, and dipping sauce—is all corn. The french fries are made from potatoes, but odds are they're fried in corn oil, the source of 50 percent of their calories. Even the salads at McDonald's are full of high-fructose corn syrup and thickeners made from corn.
