I think you'd be surprised on the snack front, but soda is addictive poison, that's true enough. The issue with the traditional diet is that it only worked when food was somewhat scarce. Even without the influx of 1st World crap accelerating the obesity/diabetes issue, those problems would remain.
I'm not denying the role of Coke, Nestle, McDonalds, etc in amplifying an existing problem into a full blown catastrophe however.
