To examine whether the form of dietary carbohydrate influences glucose and insulin responses, we studied the glucose and insulin responses to five meals--each containing a different form of carbohydrate but all with nearly identical amounts of total carbohydrate, protein, and fat--in 10 healthy subjects, 12 patients with Type I diabetes, and 10 patients with Type II diabetes. The test carbohydrates were glucose, fructose, sucrose, potato starch, and wheat starch. In all three groups, the meal containing sucrose as the test carbohydrate did not produce significantly greater peak increments in the plasma concentration of glucose or greater increments in the area under the plasma glucose-response curves than did meals containing potato, wheat, or glucose as test carbohydrates. ⋯ The meal containing fructose as the test carbohydrate produced the smallest increments in plasma glucose levels, but the differences were not always statistically significant. In healthy subjects and patients with Type II diabetes, peak serum concentrations of insulin were not significantly different in response to the five test carbohydrates. Our data do not support the view that dietary sucrose, when consumed as part of a meal, aggravates postprandial hyperglycemia.

Prospective studies have shown that children and adolescents with diabetes have a high prevalence of serious complications and a sharp reduction in life expectancy. Recently, self-monitoring of blood glucose levels has become available and, for the first time, provides a method for determining the concentration of blood glucose with considerable accuracy. We have introduced this method of control assessment to our pediatric diabetic patient population in conjunction with a program of intensified insulin administration (two or more injections per day). ⋯ The effectiveness of this program is evidenced by a progressive and significant reduction in the percentage of glycosylated hemoglobin during a period of 18 months in a majority of the subjects. These observations suggest that improved glycemic control can be achieved in young diabetics by using multiple insulin injections and self-monitoring of blood glucose levels. Whether such control can lead to a better long-term outlook for diabetics remains to be seen.
