The glycemic index (GI) is a useful method to educate the diabetics in better managing the disease. Several researchers identified its shortcomings of it being overly pessimistic and or optimistic. Despite GI weaknesses, the method faired better in explaining the rise and fall of blood glucose level with the intake of high or low glycemic carbohydrates. Thus, in this article, GI of sweet potato cultivars namely white star (Pakistan) and Beauregard (US) were estimated in a study enrolled 40 subjects (20 each normal & Diabetic) from Pakistan. The GI's were compared with that of glucose as control and Caiapo. Mean glycemic response for normal subjects was 100.28, 98.64, 98.12 and 101.32 for dehydrated white star, Glucose + Caiapo, Whit Star skin and dehydrated Beauregard, respectively. In case of diabetic subjects, the mean response of white star; Glucose + Caiapo; white star skin and Beauregard varied from 72.84; 68.03; 67.10 and 77.67, respectively. The white star skin index was lowest followed by glucose + Caiapo, dehydrated white star and Beauregard, respectively. In summary, white star and its skin followed by Beauregard indicated blood glucose lowering effect on diabetic subjects. White star skin followed by Caiapo showed blood glucose reduction in normal subjects. Both metabolic and epidemiologic data indicated that substitution of high GI with low GI carbohydrates can reduce the risk of type-2 diabetes. This in turn will improve glycemic control and.
reduce hypoglycemic episodes among those treated with insulin.
