If it came from a plant, eat it; if it was made in a plant, don't.

There’s an assumption that if someone writes in the first person it’s self-indulgent and self-regarding. I just look at it as a tool to understand the world and my experience in it. It’s not a tool to understand myself.

Yes, I very much like to have a personal stake in what I’m writing about.

Curiously, the one bodily fluid of other people that doesn't disgust us is the one produced by the human alone: tears. Consider the sole type of used tissue you'd be willing to share.

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.

Eating's not a bad way to get to know a place.

The other way that you democratize the food movement is through the public school system. If you can pay enough for the school lunch system so that it can actually be cooked and not just microwaved, so that these schools can buy local food, fresh food, because right now it's all frozen and processed, you will improve the health of the students, you will improve the health of the local economy, and you will have better performing students.
