Ok, in the US start talking about food addiction seriously and see what happens.

Do you remember how long it took to get tobacco mostly banned in the US? Do you remember how much the tobacco industry played the skeptic and introduced bunk science into the mix?

Well Coca Cola, Pepsico, Nestle, and all the other junk food companies have been on this game for years now. Want to change school curriculum?, well your political opponent has $100,000-$1,000,000 more than you from the make people fat industry. Meanwhile there are a crazy number of attack ads against you for being a crazy commie that wants to control peoples lives, you socialist bastard, you're against freedom.
