One cannot ban soda (or other unhealthy foods), see what happened with the uproar over choice over a minor tax on soda in NYC. You can not provide it at your establishment though. That's what I'm advocating for; free food (basics or prepared), but only healthy food. Making something difficult to obtain is somewhat equivalent to banning it, without the fight. "Choice" is what got us into the problem of so many having "Western" disease [1] (overweight, pre-diabetes do to diet choices).
Small nudges [2] in the right direction. If I'm providing free meals for those who need it, I'm going to provide water (cheap, healthy, and readily available in the developed world) with it, not a can of Coke.
I mean, if you want to ban Coca-Cola (like many want to ban marijuana), that's sort of a valid belief?
