Salads in Schools

This seems like a promising initiative to bring a salad bar to all schools. This blog (which is an interesting study in school lunches) post cites a short article stating that consumption of fresh fruits/veggies increased 25% after beginning to offer a salad bar at 3 different schools. Doesn't this seem obvious? Our children are crying out for healthy choices at school, why don't we respect them enough to offer salads every day as an option?
