Food choices are something fundamental you can control about yourself: what you take into your body. When so many other things are out of control and your influence over climate change - all these much larger issues - it's very hard to see any results or any progress. But everybody can see progress around food.
I think cooking is really key because it's the only way you're going to take back control of your diet from the corporations who want to cook for us. The fact is, so far, corporations don't cook that well. They tend to use too much salt, fat, and sugar - much more than you would ever use at home.
Europeans fought for shorter workdays, more vacation time, family leave, and all these kinds of things. Those haven't been priorities in America: it's been about money. You see, in the countries that fought for time, they cook more often; they have less obesity. There are real benefits to having time.
We have food deserts in our cities. We know that the distance you live from a supplier of fresh produce is one of the best predictors of your health. And in the inner city, people don't have grocery stores. So we have to figure out a way of getting supermarkets and farmers markets into the inner cities.
You know what a lima bean does when it's attacked by spider mites? It releases this volatile chemical that goes out into the world and summons another species of mite that comes in and attacks the spider mite, defending the lima bean. So what plants have - while we have consciousness, toolmaking, language, they have biochemistry.
A cow out on grass is just an incredible thing to behold... Cows and other ruminants can do things we just can't do. They have the most highly evolved digestive organ on the planet, called the rumen. And the rumen can digest grass. It takes grass, cellulose in grass, and turns it into protein, very nutritious protein. We can't do that.
To a very great extent, it's the fast-food industry that really industrialized our agriculture - that drove the system to one variety of chicken grown very quickly in confinement, to the feedlot system for beef, to giant monocultures to grow potatoes. All of those thing flow from the desire of fast-food companies for a perfectly consistent product.
Simply by starting to cook again, you declare your independence from the culture of fast food. As soon as you cook, you start thinking about ingredients. You start thinking about plants and animals and not the microwave. And you will find that your diet, just by that one simple act, that is greatly improved.
If you made all the French fries you ate, you would eat them much less often, if only because they're so much work. The same holds true for fried chicken, chips, cakes, pies, and ice cream. Enjoy these treats as often as you're willing to prepare them - chances are good it won't be every day.
I can probably earn more in an hour of writing or even teaching than I could save in a whole week of cooking. Specialization is undeniably a powerful social and economic force. And yet it is also debilitating. It breeds helplessness, dependence, and ignorance and, eventually, it undermines any sense of responsibility.
Species co-evolve with the other species they eat, and very often, a relationship of interdependence develops: I'll feed you if you spread around my genes. A gradual process of mutual adaptation transforms something like an apple or a squash into a nutritious and tasty food for a hungry animal.
