I'd be interested in any information where these young, vegetarian, non-smoking Indians started eating a high fat, high protein, low carb diet and what effect it has on blood levels. Or alternatively, an actual vegetarian diet removing anything processed like bread or pasta. The article says these people are genetically inclined to this state which may in fact be true. But a "vegetarian" diet isn't necessarily heavily based on vegetables. I'm assuming the science is looking into this but as a not so young, definitely not vegetarian white guy, when I went from a diet based on bread to a diet based on meat and vegetables with a lot of exercise on the side, I saw my blood levels drastically improve.
