Prolonged high insulin definitely correlates to insulin resistance (or diabetes). High blood glucose levels, especially fasting, indicate insulin resistance as well. What we have been talking about here is spikes in blood glucose. The spike will prompt a surge in insulin which will clear the glucose from the blood in an insulin sensitive person.
Normal glucose levels are important to good health and the next blood sugar chart shows the fasting level for a normal person and then the raising and falling of blood sugar after a meal.
Let's see if this link works: It shows normal variances over 24 hours for 21 insulin sensitive people, eating regular food.
