When you go into a fast food restaurant, you may just think about how good your meal tastes while you're eating it. But you're not thinking about all the consequences that come from that one purchase - the consequences for your body, the consequences for supporting this company and how it's treating it workers, all the way back to the farm where the potatoes were grown, or the ranch where the cattle were raised.

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

I've written about illegal immigrants in the United States; I spent a year following migrant farm workers as they were harvesting. I've written about our criminal justice system, and how it treats the victims of crime. I've been working for years now on a book about prisons in America, and I've been going into prisons and traveling around the country and seeing what's going on.

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

Fast food chains spend a large amount of marketing to get the attention of children. People form their eating habits as children so they try to nurture clients as youngsters.

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.
