It's amusing how outraged people were when Michelle Obama did her Let's Move campaign focused on eating healthy and exercise and now people are pretending it's all new.
(There was also a version before that, in 2005. The "MyPyramid." That one emphasized exercise by having a person walking up a revised version of the pyramid. Though it had a whole giant category for "milk," admittedly as a knock against it. I'll grant today's did a good job in de-emphasizing dairy compared to 2005 and 2011.)
