While a summary of the what you have read is contained within the literature review, it goes well beyond merely summarizing professional literature. It focuses on a specific topic of interest to you and includes a critical analysis of the relationship among different works, and relating this research to your work.
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 normal level of glucose in the blood, based on a fasting sample, is approximately 70-100 mg/dL. Increased levels of glucose in the blood are termed hyperglycemia, whereas decreased levels of glucose in the blood are termed hypoglycemia. They both sound similar, but by definition they're anything but.
