Glycaemic index of Pakistani staple foods in mixed meals for diabetics.

Glycaemic index of local staple foods was determined. In first phase, the post prandial blood glucose response of isocaloric portion of wheat chapati and gram flour (baisen) chapati, were compared in 11 type II diabetic patients as a part of mixed meal in fasting state, alternately. The glycaemic index of baisen chapati was 39 as compared with wheat chapati. In second phase of the study, 22 type II diabetic patients were given isocaloric portions of wheat chapati and boiled rice as a part of mixed meal alternately. The glycaemic index of rice was 98 as compared with wheat chapati. This study favours the belief that baisen chapati is better and refutes that rice is bad for diabetics. It also upholds that glycaemic index is useful for planning a diabetic diet.
