While a summary of the what you have read is contained within the literature review, it goes well beyond merely summarizing professional literature.

Dr. Richard Bernstein, who is a type I diabetic and produces no insulin of his own, has made the calculations without the influence of insulin. Apparently 1 gram of carb causes about a 5 mg/dL increase in blood sugar and 1 unit of regular insulin drives blood sugar down by 8 mg/dL. Hope this answers your question. MRE
The chart below shows what the A1C means in terms of average blood glucose levels. An average blood glucose of 150 mg/dL (milligrams per deciliter) translates into an A1C of about 7%. This is above normal, given that a diagnosis of diabetes is usually given when blood sugar levels reach about 126 mg/dL.
