The way we eat has changed more in the last 50 years than in the previous 10,000…. Now our food is coming from enormous assembly lines where the animals and the workers are being abused, and the food has become much more dangerous in ways that are deliberately hidden from us. This isn’t just about what we’re eating. It’s about what we’re allowed to say. What we’re allowed to know.

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.

One might expect that the families of murder victims would be showered with sympathy and support, embraced by their communities. But in reality they are far more likely to feel isolated, fearful, and ashamed, overwhelmed by grief and guilt, angry at the criminal-justice system, and shunned by their old friends.

There's been a growing effort to kick soda out of the schools. And governors as different as Arnold Schwarzenegger in California and Mike Huckabee in Arkansas have worked hard to get soda and junk food out of their state schools, which is good.

Fast food is inexpensive, convenient, and it tastes good. I'm all in favor of that. My problem is how heavily processed it is - how full of salt, fat, and sugar it is.

I hate the word "inevitable" because I feel like things don't have to be the way they are.

I really like visiting schools, but what I tell students isn't anywhere near as interesting to me as what they tell me.
