Corn is a greedy crop, as farmers will tell you.

Food is not just fuel. Food is about family, food is about community, food is about identity. And we nourish all those things when we eat well.

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.

Originally, the atoms of carbon from which we're made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life-the carbohydrates, amino acids, proteins, and lipids-is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.

Are we, finally, speaking of nature or culture when we speak of a rose (nature), that has been bred (culture) so that its blossoms (nature) make men imagine (culture) the sex of women (nature)? It may be this sort of confusion that we need more of.

I think that there's some brainwashing going on with this idea that we don't have time to cook anymore. We have made cooking seem much more complicated than it is, and part of that comes from watching cooking shows on television-we've turned cooking into a spectator sport. ...My wife and I both work, and we can get a very nice dinner on the table in a half hour. It would not take any less time for us to drive to a fast-food outlet and order, sit down, and bus our table.

I realize that at a certain point if we're going to change our food system, it's going to be the next generation that's going to be critical. This generation is very interested in food issues, very concerned about things like animal welfare and the impact of the food system on the environment.
