Just read a review of Michael Pollen's new book "In Defense of Food". Sounds like a sad manifesto of the American diet. A quote from the book reads, "Fast food is precisely the way you'd expect a people to eat who put success at the center of life, who work long hours (with two careers per household), get only a couple of weeks vacation each year, and who can't depend on a social safety net to cushion them from life's blows."
