Every time I've been in a public school's PE room in the last few years (since I've had my own child) there's been a board on the wall describing what's currently being done at each grade level, and at least some of the time there was information about nutrition. Whenever the kids at my neighboring school are out on the field for PE, they start out by stretching, and the teacher seems to be talking to them about preventing injury and such. It's not perfect by any means, but it seems reasonably age-appropriate.
