I beg to differ. I'm French. Not everything about our government is satisfactory (very far from it) but the one thing that's fantastic is the food in our schools: fixed menus (no pick and choose where kids would take fries and nothing else), with real meals of two main courses + cheese + desert (usually fruit).
And it shows, too; while children's obesity rates have been getting worse, they are nowhere near those in the US or UK. In fact there are virtually no fat kids under 12; after that age kids tend to be more "autonomous" (meaning more TV and more fast food lunches) but when they're young and in the school system they are incredibly healthy.
