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

I'd been eating fast food all my life without thinking about it. And the more I learned about the subject, the more intrigued I became.

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.

I think there could hardly be a more important subject than health and nutrition.

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.

We're all connected by the system, and we all have to be a part, I think, of changing it.

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.
