Equi-Quantity, Equi-Calorie and Dose of Rice on Relative Glycemic and Insulinemic Response in Diabetic Patients


Background and Aim: Diabetes mellitus is a chronic metabolic disorder with high blood sugar level. The postprandial glycemic impact of foods depends on the insulin status, which is deranged completely in a type 2 diabetic person. Dietary management of this group largely focuses on the low glycemic index (GI) food, based on equi-carbohydrate comparison, to keep the blood sugar level close to normal. But we consume whole food, along with other co-nutrients, moisture, fibre etc. The present study is aiming to assess the impact of main staple food rice with regards to Equi-Quantity, Equi-Calorie and Dose on relative glycemic and insulinemic response in diabetic patients as compared to normal group. Method: Blood samples of diabetic patients with stable blood sugar under medicinal treatment and paired normal patients (n = 6 + 6) were collected after an overnight fast and up to 2 hours post consumption of test and standard food on different occasions. Glucose and insulin levels were measured using glucometer (Abbott pharmaceuticals) and ECLIA method. Result: Equi-quantity of rice exerts a much lower glycemic and insulinemic response in comparison with bread in both normal and diabetic individuals and the response to rice does not show a proportional increase even when the quantities are doubled. Rice has higher moisture content which acts as energy diluent, decreasing the total starch in equivalent quantities. Equi-calorie (132 kcal) quantity comparison of rice (100 g) and bread (50 g) showed a much lower glycemic and insulinemic impact on rice in diabetic individuals, even though quantity is double and satiety level reaches earlier than low moisture food bread in equi-calorie quantity. The normal individuals, with normal insulin response can control the glycemic response to lower levels than those of diabetic subject. Conclusion: Rice having lower glycemic and insulinemic impact is a better suited food for diabetic individuals who already have a compromised insulin status.
