Schools say no to soft drinks, impact is minimal

Recent research shows that when elementary schools ban soft drinks, the improvement in kids' health is minimal.

Schools who have removed soda vending machines have done so in an effort to improve student health. But research shows that fifth graders who attend schools where soda is banned consume only 4% less than students who have access to soda at school.

As far as I'm concerned, 4% is 4% is 4%. It may be a small improvement, but it's an improvement none-the-less. And since soda bans are relatively recent -- starting in 2003 in California -- I think time will still tell. It takes time to change kids' tastes and preferences. Parents just have to get on board, too, and save soda for the rare treat or avoid it altogether.
