It is clear that diabetic patients need artificial sweeteners in their food and drinks in order not to increase their plasma glucose level while still enjoying the same taste in their food as the ordinary sugar.The aim of this study is to investigate the effect of diet Pepsi, which is available in the local market on the glycaemic index of type 2 diabetic patients. The data for this cross sectional study were collected from 33 diabetic patients(the age range for whole sample was 33-77 years ,male:19,female:14 ) who were attending to the National Diabetes Center in Al-Mustansiriya University. All patients were having type 2 diabetes and were treated with oral hypoglycemic agents or diet alone. Each patient included in this study was in a fasting state (over night fasting), and had not received any medication before the interview. After fasting plasma glucose was measured for every patient, the patients were asked to drink 330 cc of diet Pepsi drink and the plasma glucose level was measured after two hours( postprandial) from drinking that diet Pepsi meal .The results obtained from this study ,indicate clearly a significant difference between the means of fasting and the postprandial plasma glucose (202±88), (184±75) mg/dl respectively, it was lower for the postprandial plasma glucose (P <0.00001), also the result obtained showed a significant difference among means of fasting plasma glucose and postprandial plasma glucose for male, and female patients,it was higher in female patients (P =0.05) . The decrement in the mean of the level of plasma glucose after taking diet Pepsi was of significant statistical value, which indicates that this product is really sweetened by synthetic sweeteners and has no negative effect on plasma glucose level for the patients who were included in this study.
