It's been a mystery to me and a disappointment why conversation about health care reform hasn't turned more attention to the subject of food.

Half of all broccoli grown commercially in America today is a single variety- Marathon- notable for it's high yield. The overwhelming majority of the chickens raised for meat in America are the same hybrid, the Cornish cross; more than 99 percent of turkeys are the Broad-Breasted Whites.

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.

Eat mostly plants, especially leaves.

That eating should be foremost about bodily health is a relatively new and, I think, destructive idea-destructive not just the pleasure of eating, which would be bad enough, but paradoxically of our health as well. Indeed, no people on earth worry more about the health consequences of their food choices than we Americans-and no people suffer from as many diet-related problems. We are becoming a nation of orthorexics: people with an unhealthy obsession with healthy eating.

Measured against the Problem We Face, planting a garden sounds pretty benign, I know, but in fact it’s one of the most powerful things an individual can do - to reduce your carbon footprint, sure, but more important, to reduce your sense of dependence and dividedness: to change the cheap-energy mind.

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