One of the powerful things about the food issue is that people feel empowered by it. There are so many areas of our life where we feel powerless to change things, but your eating issues are really primal. You decide every day what you're going to put in your body and what you refuse to put in your body. That's politics at its most basic.

For great many species today, fitness means the ability to get along in a world in which humankind has become the most powerful evolutionary force.

I made the unexpected but happy discovery that the answer to several of the questions that most occupied me was in fact one and the same: Cook.

A garden should make you feel you've entered privileged space -- a place not just set apart but reverberant -- and it seems to me that, to achieve this, the gardener must put some kind of twist on the existing landscape, turn its prose into something nearer poetry.

The food system is a very complex beast. There are people who are going to get their food at Wal-Mart or at Safeway; they're not going to the farmers' market. Those people need choices too.

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.

Plus, I love comic writing. Nothing satisfies me more than finding a funny way to phrase something.
