New Glycemic Tables

David Mendosa Health Guide December 19, 2008
  • Ever since 1995, when the first international tables of glycemic index appeared in print and on my website, they have been the gold standard for determining the glycemic index of as many foods as researchers had tested at that point. Now, in the third revision of the international tables you can fin...

    There is a 'low grade' controversy regarding this index. Some swear by it, others think it 'off the wall'. Here is my take. Some (pre)diabetics mostly have lost their first phase insulin response. This is the load of insulin that the pancreas can dump as fast as you can absorb carbs.

    There is a 'low grade' controversy regarding this index. Some swear by it, others think it 'off the wall'. Here is my take. Some (pre)diabetics mostly have lost their first phase insulin response. This is the load of insulin that the pancreas can dump as fast as you can absorb carbs. After this the second phase involves the steady production and release of insulin to mop up whatever excess glucose there is in the blood stream. If you still have a little first phase and a healthy second phase, then the glucose index helps - you don't overload with too much glucose at any one time. Also if you have some second phase, a basal dose of insulin may be enough to help your pancreas and its output of insulin to keep your blood sugars in a safe range.

     

    But at a certain point of no first phase, and sufficiently weakened second phase your pancreas no longer can put out enough insulin even to cope with protein. At that point you must bolus even for 'bacon and eggs', or that T-bone steak. You are truly injected insulin dependent, and glycemic index is largely irrelevant. Lentils, Dreamfield Pasta, whatever, sooner are later it is going to show up in my blood as glucose, and I will need to inject insulin to cover it. Actually I started metering while I still had a good second phase response, and tracked it over the months as it declined, and I needed to add insulin to my diet/exercise regimen.

     

    This does raise a suspician that I could be a Type 1.5. Having gone very low carb a Type 2 likely would not have experienced as fast a degrade in natural insulin as I did. The tests for this are not particularly accurate and are expensive, and as my current doctor says, it would not change my treatment at all. He (my fourth doctor) is the first one who would support my goals of truly normal BGs, last A1C for me was 4.9.
