Listening to a San Francisco dietician blithering on NPR this morning coming in to work. I don't remember *exactly* what she said, but it sounded a lot like "Would you believe that parents expect you to produce actual evidence, or at least studies that give the appearance of evidence (with numbers and everything!) before they'll let you experiment on their brats? We found a couple of dodgy studies that's letting us feed our middle-schoolers the junk *we* approve of, rather than what the kids might want to eat. Look! Sushi!"
