There have been pushes to remove soda from school vending machines, limit the size / add extra taxes on bigger soda containers, etc. But it's often "crazy California" doing it, so a whole chunk of the country writes it off as political or something, or it doesn't get passed due to lobbying, etc. But it's not true that no one is trying to stop it.

As much as I like a cold Coke (Coke >>> Pepsi :-) on a hot day, I also realize it's bad for me, and I'm drinking a lot more Spindrift these days. And despite the fact that I rarely drink more than say, 2 cans a day (i.e. I can generally control it), I would still vote to limit the amount of sugar in any beverage to like 1/10 that of Coke, just for general health reasons. Of course, then stores will probably see an uptick in sugar cube sales or something.. Gotta feed the addiction.
