People have traditionally turned to ritual to help them frame and acknowledge and ultimately even find joy in just such a paradox of being human - in the fact that so much of what we desire for our happiness and need for our survival comes at a heavy cost.

Cheap food is an illusion. There is no such thing as cheap food. The real cost of the food is paid somewhere. And if it isn't paid at the cash register, it's charged to the environment or to the public purse in the form of subsidies. And it's charged to your health.

Corn is an efficient way to get energy calories off the land and soybeans are an efficient way of getting protein off the land, so we've designed a food system that produces a lot of cheap corn and soybeans resulting in a lot of cheap fast food.

One surprise is how deeply the food system is implicated in climate change. I don't think that has really been on people's radar until very recently. 25 to 33 percent of climate change gases can be traced to the food system. I was also surprised that those diseases that we take for granted as what will kill us - heart disease, cancer, diabetes - were virtually unknown 150 years ago, before we began eating this way.

We're always projecting our moral categories on things. I think that's inevitable. But capitalism places no particular value on morality. Morality in the market is enforced by contract and regulation and law, because morality is understood to be in conflict with the motive force of greed and accumulation.

Every peasant cuisine has incredible ingenious tricks for getting a lot of nutrition out of a small amount of ingredients. There are people who don't have the money to invest in better food, but perhaps they have the time. There's a trade-off: The more time you're willing to put into food preparation, the less money you have to spend.

Studies show that organically grown crops produce more of the things (ascorbic acid, lycopenes, resveratrol, flavonols in general, etc) that our bodies need and also have less toxic residue. Science is still catching up with this. J. Agric. Food. Chem. Vol. 51, no. 5, 2003.
