I found this rant a bit vapid - you'll find more usable information here: http://news.ycombinator.com/item?id=1041452 (or read Gary Taubes' Good Calories, Bad Calories).
I think Oliver clearly identifies a problem (and quite passionately believes in what he says), but the solution seems squishy - "fighting obesity" and "education" are great ideas but when you empower people with bad ideas that's probably worse than useless. Besides, the problem isn't educating the kids but the parents.
