Glycaemic indices of the commonest Pakistani foods i. e. breakfast [Paratha + Omelette] , snack item [Samosa + Cup of tea] and frequently taken meal [mutton pulao with yogurt] were determined.
Seven healthy male individuals aged between 27-35 years with normal glucose tolerance participated in the study. After performing oral glucose tolerance test the test meals yielding 75 g carbohydrates were consumed in random order on separate morning one week apart with usual precaution of overnight fast. Glucose produced highest incremental blood glucose response and two hour postprandial fall was more as compared to test meals. Meal I [Paratha + Omellette] produced lowest blood glucose response with two incremental peaks. Meal II [Samosa + Cup of tea] produced overall higher blood glucose response as compared with meal I and III. Meal III [Mutton Pulao + yogurt] produced intermediate glucose response when compared with meal I and II. Glycaemic index [Gl] of meal I was significantly lower as compared to that of glucose, meal II and meal III. Meal II had lower Gl when compared with glucose but higher than those of meal I and meal III. Meal III had intermediate Gl when compared with other test meals. The insulin response generally paralleled the glucose response. However, meal III produced higher insulin response as compared to other meals in the first half time of observations. These results indicated that Pakistani foods having high fibre content produced low Gl and can be advised to diabetic patients in appropriate amounts by considering their pattern of incremental blood glucose response so that blood glucose levels in these patients may not abruptly increase post prandially
