This is a repost from: The Glutton Free Diet
Before being told that I was pre-diabetic, I never gave a second thought to what the risk factors might be. In my mind, I was still fairly young and fit, and worrying about diabetes was the furthest thing from my mind. That diagnosis meant taking a crash course in learning what exactly type 2 diabetes was, and how I could prevent it...
I was involved with an online discussion today about what some of the causes of type 2 are, and was reminded how many misconceptions are out there. One person was asserting that the only thing that mattered in prevention of type 2 was eliminating virtually all sugars, starches, and carbohydrates from your diet. According to them, even whole grains were the enemy, and would contribute to blood glucose level spikes. Therefore, they suggested that everyone eat a highly restrictive low-carb diet, even to the point of eliminating complex carbohydrates -- something that goes a little too far, in my opinion .
I couldn't be too judgmental about that viewpoint, though; as it wasn't long ago that believed the same thing -- I thought that all I had to do was cut out carbs and everything would be OK. Well, it turns out that there's more to it than just that.
First, let's look at what type 2 diabetes is: Facts About Type 2
With type 2, either your body doesn't produce enough insulin on its own, or your body's cells ignore the insulin. When you eat starches and sugars, your body breaks them down into glucose, which is a basic fuel for the cells of your body. Insulin moves the glucose from the blood into the cells. If you aren't producing enough insulin on your own, or your body's cells are stressed to the point that they resist the insulin altogether, then you end up with excess glucose levels in your blood.
As noted in the link, having too much glucose in the blood can starve your cells for energy, and over time high glucose levels may harm your eyes, heart, kidneys, and nerves.
So, what exactly causes type 2 diabetes? Well, there are a number of risk factors involved, so it's difficult to say that any one thing causes it. The main risk factors include family history of type 2 diabetes, ethnicity (blacks, Hispanics, Native Americans, or Asian Americans), body weight (obesity), low activity level, and age (40-45 and older).
Notice that carbohydrate intake is not part of that list. That doesn't mean that you shouldn't watch the amount of sugar you ingest, because obesity is still a major risk factor, and there are a lot of calories in simple sugars -- and if you take in more calories than you burn, you will gain weight.
It's obvious that there is a lot of misinformation out there about type 2, so the American Diabetes Association was nice enough to put together a fact sheet listing many myths about diabetes: Diabetes Myths
If you are concerned that you may be at risk for type 2 diabetes, the ADA also has a Risk Test that you can take. I took the test based on my current weight and activity level, and it put me at "low risk". But when I went back an entered my formerly obese weight and lower activity level into the test, it told me I was "high risk".
If you have more than one of the risk factors, and the risk test places you in the "high risk" range, it isn't too late to reverse the trend. Eat a balanced diet. Exercise. Burn more calories than you take in. Type 2 Diabetes doesn't have to be something that "happens to you" -- you can choose to make sure that you beat it before it beats you.
