I think for real change to happen, it's going to have to come from the kids, the community, the teachers, the parents.

There's a real strong link today between soda consumption and obesity among children.

So for everything I do, I'm very clear about what I'm doing, and I tell people what it's about. They get a sense of what I'm thinking. I don't let people think I'm going to write something in praise in the meatpacking industry, and then they read it and it's actually attacking the meatpacking industry.

If the market does indeed embody the sum of all human wishes, then the secret ones are just as important as the ones that are openly displayed.

Yes, a cheeseburger and fries is probably my favourite meal. But I don't eat ground beef anymore.

I think it's possible to have food that's healthy, that's good for you to eat, that's also inexpensive. We don't have to have this cheap, unhealthy food being so aggressively promoted.

There's also a growing trend toward having gardens in schools to literally show kids where food comes from by having them grow and prepare their own food. There's also a movement that's bringing farmers into schools and creating relationships between local farms and local cafeterias, so that instead of frozen mystery meat, you have fresh produce that's coming from the area that has a name and a face associated with it.
