Keeping kids healthy is an absolutely unacceptable explanation for this. I could think of more plausible reasons, but if the claim is taken at face value the direct implication is that schools have more authority to police kids health than parents. If this is the case, it would be perfectly logical to impose requirements for home diet as well.
