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.

Ripe vegetables were magic to me. Unharvested, the garden bristled with possibility. I would quicken at the sight of a ripe tomato, sounding its redness from deep amidst the undifferentiated green. To lift a bean plant's hood of heartshaped leaves and discover a clutch of long slender pods handing underneath could make me catch my breath.

The best farming systems are ones where animals and plants are put into a synergistic relationship.

Culture, when it comes to food, is of course a fancy word for your mom.

Our ingenuity in feeding ourselves is prodigious, but at various points our technologies come into conflict with nature's ways of doing things, as when we seek to maximize efficiency by planting crops or raising animals in vast mono-cultures. This is something nature never does, always and for good reasons practicing diversity instead. A great many of the health and environmental problems created by our food system owe to our attempts to oversimplify nature's complexities, at both the growing and the eating ends of our food chain.

Curiously, the one bodily fluid of other people that doesn't disgust us is the one produced by the human alone: tears. Consider the sole type of used tissue you'd be willing to share.

Don't eat anything incapable of rotting.
