Nice interview in Grist magazine:
The new book is called In Defense of Food: An Eater’s Manifesto. It’s a book that really grew out of questions I heard from readers after Omnivore’s Dilemma, which was basically so how do you apply all this? Now that you’ve looked into the heart of the food system and been into the belly of the beast, how should I eat, and what should I buy, and if I’m concerned about health, what should I be eating? I decided I would see what kind of very practical answers I could give people.
I spent a lot of time looking at the science of nutrition, and learned pretty quickly there’s less there than meets the eye, and that the scientists really haven’t figured out that much about food. Letting them tell us how to eat is probably not a very good idea, and indeed the culture — which is to say tradition and our ancestors — has more to teach us about how to eat well than science does. That was kind of surprising to me.
