Why don't we pay more attention to who our farmers are? We would never be as careless choosing an auto mechanic or babysitter as we are about who grows our food.

Avoid food products that make health claims. at meals and eat them only at tables. And no, a desk is not a table.

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.

Be the kind of person who takes supplements - then skip the supplements.

Another thing cooking is, or can be, is a way to honor the things we're eating, the animals and plants and fungi that have been sacrificed to gratify our needs and desires, as well as the places and the people that produced them. Cooks have their ways of saying grace too... Cooking something thoughtfully is a way to celebrate both that species and our relation to it.

Imagine for a moment if we once again knew, strictly as a matter of course, these few unremarkable things: What it is we're eating. Where it came from. How it found its way to our table. And what, in a true accounting, it really cost.

We are not only what we eat, but how we eat, too.
