What does unhealthy food look like?

David Freedman has a piece at The Atlantic about healthy foods, unhealthy foods — and the "healthy" foods that are actually probably not that healthy, despite coming to you all natural and un-processed. I want to like the piece more than I actually do. For instance, Freedman has some issues with misrepresenting the positions of the people he's arguing against. For instance, I think he and Michael Pollan would probably agree that downing lots of 300-calorie fruit smoothies isn't the best way to get in shape. But it's an interesting read, especially if you just focus on the key point: Healthy food doesn't have to be limited to what you buy at Whole Foods or the farmer's market.
