Diet soda may soon be allowed back in Colorado's high school cafeterias and vending machines.
The state Board of Education on Wednesday signaled its intention to end a ban on the beverages.
Colorado banned soda and diet soda from high school cafeterias and vending machines in 2009. But new federal rules issued last month allow diet drinks in schools.
So state education officials say they worry about districts having to follow conflicting guidelines, and back the change. But health advocates say sweeteners in diet sodas unhealthy and harm teeth.
The board will take a final vote in September.
