The standard marker for blood sugar is a fasting glucose test. Unfortunately, by the time these glucose levels are high, we have missed an opportunity to work with the body to regulate blood sugar. The better test a hemoglobin A1C and if that is elevated, an insulin test with a glucose tolerance test. Insulin resistance has become epidemic in our country with 1 in 4 of us having insulin resistance. If you are having trouble losing weight or weight is accumulating around your mid-section, if cholesterol or blood pressure is creeping up, then look to insulin resistance as a potential culprit. Chromium is a wonderful mineral to regulate insulin resistance.
