The other way that you democratize the food movement is through the public school system. If you can pay enough for the school lunch system so that it can actually be cooked and not just microwaved, so that these schools can buy local food, fresh food, because right now it's all frozen and processed, you will improve the health of the students, you will improve the health of the local economy, and you will have better performing students.

The other thing that soy contributes to, of course, is hydrogenated oil. This is the main oil. This is the fast-food oil.

When a livestock farmer is willing to "practice complexity"-to choreograph the symbiosis of several different animals, each of which has been allowed to behave and eat as it evolved to-he will find he has little need for machinery, fertilizer, and, most strikingly, chemicals. He finds he has no sanitation problem or any of the diseases that result from raising a single animal in a crowded monoculture and then feeding it things it wasn't designed to eat. This is perhaps the greatest efficiency of a farm treated as a biological system: health.

People say they don't have time to cook, yet in the last few years we have found an extra two hours a day for the internet.

Wrangham cites several studies indicating that in fact humans don't do well on raw food: they can't maintain their body weight, and half of the women on a raw-food regimen stop menstruating. Devotees of raw food rely heavily on juicers and blenders, because otherwise they would have to spend as much time chewing as the chimps do. It is difficult, if not impossible, to extract sufficient energy from unprocessed plant matter to power a body with such a big, hungry brain.

I think that there's some brainwashing going on with this idea that we don't have time to cook anymore. We have made cooking seem much more complicated than it is, and part of that comes from watching cooking shows on television-we've turned cooking into a spectator sport. ...My wife and I both work, and we can get a very nice dinner on the table in a half hour. It would not take any less time for us to drive to a fast-food outlet and order, sit down, and bus our table.

But human deciding what to eat without professional guidance - something they have been doing with notable success since coming down out of the trees - is seriously unprofitable if you're a food company, a definite career loser if you're nutritionist, and just plain boring if you're a newspaper editor or reporter.
