Updating the food pyramid

The well known food pyramid, offering simple prescriptions for a good diet, is now just over ten years old. Scientific American have an article from earlier this year on what we've learnt about dietry health in the intervening years. It's both fortunate and unfortunate that, as the title of the article ("Rebuilding the Food Pyramid") suggest, we've learnt a fair bit more. Unfortunate, because better health will require changes in habits and established lore, but fortunate, because it ought to help bring us closer to that goal.
