As an Australian, I find it crazy that getting food from a cafeteria at school is the norm in the US. In Australia you bring food from home 90% of the time. On special occasions or every now and then you order lunch from the canteen.

This mechanism does cause troubles for the poorest kids, though. Poor families send their kids to school without lunch, or with very unhealthy food (because that's cheapest).

I doubt the taxes necessary to make this happen would be close to the price parents pay for food (and the time they spend preparing meals for their young kids).
