Eat food. Not too much. Mostly plants.

The energy I was sensing in audiences was political energy, as much as anything else.

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.

Corporations cook very differently from how people do.

At home I serve the kind of food I know the story behind.

We have food deserts in our cities. We know that the distance you live from a supplier of fresh produce is one of the best predictors of your health. And in the inner city, people don't have grocery stores. They have to get on a bus and take a long ride to get to a source of fresh produce.

Culture, when it comes to food, is of course a fancy word for your mom.
