San Francisco bans coke from city vending machines

In a new directive geared towards fighting obesity, San Francisco mayor Gavin Newsom is banning the sale of Coke, Pepsi, and Fanta Orange in vending machines on city property. From SFGate:
Newsom's directive, issued in April but whose practical impacts are starting to be felt now, bars calorically sweetened beverages from vending machines on city property.

That includes non-diet sodas, sports drinks and artificially sweetened water. Juice must be 100 percent fruit or vegetable juice with no added sweeteners. Diet sodas can be no more than 25 percent of the items offered, the directive says.

There should be "ample choices" of water, "soy milk, rice milk and other similar dairy or non dairy milk," says the directive, which also covers fat and sugar content in vending machine snacks.

It's a neat idea, but I wonder how effective it is.
