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

Eat food. Not too much. Mostly plants.

Food is also about pleasure, about community, about family and spirituality, about our relationship to the natural world, and about expressing our identity. As long as humans have been taking meals together, eating has been as much about culture as it has been about biology.

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.

Not everyone can afford to eat well in America, which is a literal shame, but most of us can: Americans spend less than 10 percent of their income on food, less than the citizens of any other nation.

Farms produce a lot more than food; they also produce a kind of landscape and a kind of community.

Stop eating before you're full.
