That anyone should need to write a book advising people to "eat food" could be taken as a measure of our alienation and confusion. Or we can choose to see it in a more positive light and count ourselves fortunate indeed that there is once again real food for us to eat.

The longer I've looked at these questions, of the American diet and the public health crisis that we face because of that diet, the more I've come to the conclusion that the collapse of cooking is a big part of the problem.

Food consists not just in piles of chemicals; it also comprises a set of social and ecological relationships, reaching back to the land and outward to other people.

Cooking might be the most important factor in fixing our public health crisis. It's the single most important thing you can do for your health.

If you care about the animals, actually, organic might not be the best answer because now we have organic feedlots, organic factory farms. If you care about the environment - pesticides, especially - organic is the answer.

We have food deserts in our cities. We know that the distance you live from a supplier of fresh produce is one of the best predictors of your health. And in the inner city, people don't have grocery stores. They have to get on a bus and take a long ride to get to a source of fresh produce.

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.
