Yes, it was late 2011 when the legislation went through. It was 2012/13 when the "healthy balanced food" programme was pushed out. It was promoted very widely by central government, with lots of publicity, trying to persuade people to adopt the recommend mix of meat, fish, fruit and vegetables. "Eat at least five different vegetables a day" was one of the slogans.
To be fair, one of the aims was to get the French people (not just children in schools) to eat a more balanced diet, rather than lots of red meat and chips. Workers in restaurants often still opt for the traditional steak and chips, though! But the implications for vegetarian or vegan children were not considered and protests were few (as discussed earlier in this thread).
Perhaps I gave the wrong impression in referring to these rules as "new" (my bad choice of word), but it wasn't that long ago.
