A few years ago, I read about the problems Asian people faced in having increasing diabetes. And in the US, doctors were warned about not making the mistake in believing that their trim-looking Asian patients having low risks of this disease.
Regarding the rapidly increasing diabetic rate in formerly diabetic-free countries, we can just look at videos of street scenes in Asian countries 30-40 years ago, compared to now. People now have more weight, due to an increase in calorie intake. Technology increases food production, and world trade makes food more affordable. Rural people now move to the cities and work in high-tech factories. They earn more and now eat more.
Ah, the curse of abundance.
My parents and my siblings all had or have the tendency of high blood glucose. And that's why I am paying particular attention to my own condition, and resolve to do my own finger-pricking test for fasting glucose every month as described earlier. It is easy, not painful, and gives me advance warning for me to take corrective action. If I wait for the annual exam blood test (I see my doctor only once a year), it may be too late, or the correction regime is harder.
Right now, simply by not eating anything after dinner and not having breakfast which I rarely do anyway, avoiding sweets, and taking a walk immediately after a meal, both my wife and I have been able to keep our fasting blood glucose below 100, often under 90. We still eat tons of carb like bread and rice.
As mentioned in earlier threads, prior to taking the above simple steps, my BG was never below 90, even when I was in my 40s. My wife BG had always been low until a couple of years ago when she ate 2 or 3 ears of sweet corn a day during the corn season, and her BG shot up to more than 120! Without doing our own test, we would be totally oblivious to the problem, and just eat our way to the grave.
I will add that we are always reasonably fit. My BMI is never above 26, and currently 23. My wife is trimmer with a BMI of 21.
