Comparison of serum glucose, insulin, and glucagon responses to
different types of complex carbohydrate in noninsulin-dependent
diabetic patients
PA Crapo, J Insel, M Sperling and OG Kolterman


We have studied the acute effects of oral ingestion of dextrose, rice,
potato, corn, and bread on postprandial serum glucose, insulin, and
glucagon responses in 20 diabetic subjects with nonketotic, noninsulin
requiring fasting hyperglycemia. The carbohydrate loads were all
calculated to contain 50 g of glucose. The data demonstrate that 1)
dextrose and potato elicited similar postprandial serum glucose
responses whereas rice and corn elicited lower responses, with bread
intermediate; 2) postprandial insulin responses were relatively flat
but rice ingestion led to significantly lower insulin responses than
did potato; 3) urinary glucose excretion during the 3 h after
carbohydrate ingestion was greatest following dextrose and least after
rice and corn. In conclusion, there is a range in the magnitude of
postprandial hyperglycemia after ingestion of different complex
carbohydrates in diabetic patients with fasting hyperglycemia and
emphasis on the use of the less hyperglycemic starches could be of
therapeutic value in controlling hyperglycemia.
