We're spending, on average, 27 minutes a day cooking and about four minutes cleaning up, so basically about a half hour. Any one of TV shows takes twice as long to watch as that, which I think is very interesting because the main excuse people give for not cooking is they don't have time to cook, but somehow they're finding time to watch other people cook or eat on TV.

Corn is the hero of its own story, and though we humans played a crucial supporting role in its rise to world domination, it would be wrong to suggest we have been calling the shots, or acting always in our own best interests. Indeed, there is every reason to believe that corn has succeeded in domesticating us.

People forget that eating represents their most profound engagement with the natural world. Through agriculture is how we change the world, more than anything else we do.

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.

Eat with consciousness. When you eat with consciousness, and you know what you're eating, and you eat it in full appreciation of what it is, it's enormously satisfying.

In Joel's view, that reformation begins with people going o the trouble and expense of buying directly from farmers they know - "relationship marketing," as he calls it. He believes the only meaningful guarantee of integrity is when buyers and sellers can look one another in the eye, something few of us ever take the trouble to do. "Don't you find it odd that people will put more work into choosing their mechanic or house contractor than they will into choosing the person who grows their food?"

Is it just a coincidence that as the portion of our income spent on food has declined, spending on health care has soared? In 1960 Americans spent 17.5 percent of their income on food and 5.2 percent of national income on health care. Since then, those numbers have flipped: Spending on food has fallen to 9.9 percent, while spending on heath care has climbed to 16 percent of national income. I have to think that by spending a little more on healthier food we could reduce the amount we have to spend on heath care.
