DENVER -- Diet sodas soon could be for sale inside Colorado public high schools.
The Colorado Board of Education is set to vote Wednesday on lifting a ban that has been in effect for seven years.
Lifting the ban would align the state's rules with federal guidelines, which aren't as strict.
Some school districts support the move, saying it's a challenge enforcing two policies.
But health advocates worry that allowing diet sodas in state public schools would only feed health problems, including obesity and tooth decay.
A number of groups, including the Colorado PTA, have spoken out against the change.
It approved, the new guidelines would take effect for the 2017-18 school year.
Board members pointed out that individual school districts would still be able to implement their own rules.
