corn

Wet milling (to produce starch) is an energy-intensive way to make food; for every calorie of processed food it produces, another ten calories of fossil fuel energy are burned.

Planted, a single corn seed yielded more than 150 fat kernels, often as many as 300, while the return on a seed of wheat was something less than 50:1

Try as we might, each of us can eat only about 1500 pounds of food a year. What this means for the food industry is that its natural rate of growth is somewhere around 1% every year (growth of American population).

Today it [high fructose corn syrup] is the most valuable food product refined from corn, accounting for 530 million bushels every year. (A bushel of corn yields 33 pounds of fructose)

Farmers facing lower prices have only one option if they want to be able to maintain their standard of living, pay their bills, and service their debt, and that is to produce more [corn]

So this is what commodity corn can do to a cow: industrialize the miracle of nature that is a ruminant, taking this sunlight- and prairie grass-powered organism and turning it into the last thing we need: another fossil fuel machine. This one, however, is able to suffer.

But carbon 13 [the carbon from corn] doesn't lie, and researchers who have compared the isotopes in the flesh or hair of Americans to those in the same tissues of Mexicans report that it is now we in the North who are the true people of corn.... Compared to us, Mexicans today consume a far more varied carbon diet: the animals they eat still eat grass (until recently, Mexicans regarded feeding corn to livestock as a sacrilege); much of their protein comes from legumes; and they still sweeten their beverages with cane sugar. So that's us: processed corn, walking.
