I am confident that we will see a growing consensus about the most effective way to transform food in America: building a real, sustainable and free school-lunch program.

How we eat can change the world

The way we subsidize food makes it cheaper to go to McDonald's and get a hamburger than a salad, and that's insane. It's pure government policy.

I think the biggest impediment to fixing the food system in the United States is that we expect food to be cheap. We want to by other things with our money. We're so disconnected from agriculture - from the culture in agriculture.

The problem with living in a fast-food nation is that we expect food to be cheap.

In terms of kids not liking the food, I am shocked. I know that it's not true. I know that when kids are not educated about healthy food, they have a resistance to it. The resistance comes, again, from the fast-food culture.

I love those tiny little onions in the spring that are so small they're almost like a little chive.
