It is quite common to assume that the main factor with diabetes type 2 is genetic, given how often it runs in families. However, countless examples of one sibling developing type 2 and the others not, appear to counter that theory. I personally believe that there is a strong similarity between lung cancer and type 2 Diabetes. Even if you are a heavy smoker you won’t get lung cancer if you don’t have the susceptibility genes. And if you have the genes but never smoked you have a good chance of living to 90. The loser in that equation are those who have the susceptibility genes and choose to smoke for years, inevitably ending up suffering in a hospital bed for terminally ill patients.
As for diabetes type 2, a couple of parallels to smoking and lung cancer come to mind. I believe that the susceptibility gene for type 2 runs in my family. My paternal grandmother spent the last 20 years of her life blind, due to damage to her eyes from her diabetes type 2. I was diagnosed with diabetes type 2 nearly 20 years ago, However neither of my two parents, two sisters or four nieces have exhibited any sign of diabetes. And guess what, my grandmother and myself are the only people in our extended family who through unhealthy lifestyles allowed ourselves to become obese. All the rest, my parents, siblings, nieces are fit and slim people.
Then look at China. Half a century ago diabetes type 2 was virtually unknown in this vast country. Then with modernization the country has become swamped with burger king, pizza hut, macdonalds etc. fast food joints. Walk down the streets of Beijing or Shanghai and you see lots of people, mainly adolescents, who are obese.
At last count, according to the World Health Organization, there are approximately 26 million registered type 2 diabetics in China. And for the most part, that is compliments of the American fast food industry, but also to the fact that the underlying genes that allow type 2 to develop were unused in a population that worked hard and ate brown rice and vegetables at most of their meals.
Again, I can hear cries that this is all anecdotal evidence. Well if bombs start exploding around you and you look up and see a Russian MIG bomber flying overhead, the evidence that the Russian plane was responsible is only anecdotal. Still the only sensible thing to do would be to head for the nearest bomb shelter…
