Don't be so sure about that. My family is Indian and Catholic, which means our diets have always been much more like the "typical" American diet... lots of beef, pork, and chicken; less ghee than vegetarian Indian food; no fried food (why fry vegetables, when you can just cook in animal fat?); and about as much potato and bread as in the US. Grandparents still have or had all the problems in the article even though they don't eat any added sugar, and have cut down on fats, etc. Parents and aunts/uncles shaping out to be the same way.
