Interesting! I have no evidence but I got the impression that Turkiye's sugar industry (the richest man owns Ülker, a confectionary conglomerate) was unnaturally large and not always that way...
I could not find the recent article I heard on the radio but this covers it https://www.npr.org/sections/goatsandsoda/2017/04/05/5220383... and there's a separate wikipedia entry just for obesity in Mexico, it's hit them so hard, it's like a hotbed for studies https://en.wikipedia.org/wiki/Obesity_in_Mexico
I remember some report about how Mexico had a very different rate of obesity from the USA until some of the free trade agreements kicked in and multinational food companies with USA branches started getting a bigger share in the Mexican market, ending up with the Mexican diet resembling more of the USA diet.
