Don't public school lunches have to follow the food guide recommendations? Assuming that hasn't changed since I was in school, a recommendation based on something other than industry lobbying could help quite a bit with children's health and long term outlooks.
That said, I obviously don't know what this administration would propose as a new recommendation so I'm not implying it will be better. We'd have to see what they put out, if anything, to get an idea about that.
