It's not food if it arrived through the window of your car.

Of the seven deadly sins, surely it is pride that most commonly afflicts the gardener.

Don't eat anything incapable of rotting.

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.

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.

There's a schizoid quality to our relationship with animals, in which sentiment and brutality exist side by side. Half the dogs in America will receive Christmas presents this year, yet few of us pause to consider the miserable life of the pig - an animal easily as intelligent as a dog - that becomes the Christmas ham.

Eat foods made from ingredients that you can picture in their raw state or growing in nature.
