After eating meals high in carbohydrates, a persons blood sugar level may increases from about 80 mg/100 ml of blood up to 120 mg/100 ml of blood. The blood sugar level is maintained within a fairly narrow range in spite of such a large intake of sugar from the carbohydrates. This is a perfect example of....
