"Eat food. Not much. Mostly plants." That's Michael Pollan, investigatory journalist who has (whether or not this was intended) turned into a food activist. Whether you agree with him doesn't make what he's saying less interesting. We do things he doesn't like (buy bagged salad--but he makes me wish I didn't), but other things he does like. I see where he's coming from.
Anyway, he was on Leonard Lopate, one of the best interviewers in public radio. Find the link here to hear from the man himself, the "vegetarian before 6pm."
