The longer I've looked at these questions, of the American diet and the public health crisis that we face because of that diet, the more I've come to the conclusion that the collapse of cooking is a big part of the problem.

...There's a lot of money in the Western diet. The more you process any food, the more profitable it becomes. The healthcare industry makes more money treating chronic diseases (which account for three quarters of the $2 trillion plus we spend each year on health care in this country) than preventing them.

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.

Better to pay the grocer than the doctor.

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. They have to get on a bus and take a long ride to get to a source of fresh produce.
