Introduction: Carbohydrate contents of different foods may have different effects on postprandial blood glucose. This study was done to measure and compare glycemic indices and some nutrients in three types of rices. Material and methods: This study was conducted to compare the glycemic effects of 50g carbohydrate in the Basmati, Kazemi and Sorna Perl types of rice in normal subjects. Thirty healthy subjects (13 male and 17 female), aged between 20-40 years, were selected, and were evaluated 4 times at 1 week intervals. On the first day, all subjects consumed 50 gram glucose they were then divided into 3 groups. Each group consumed one of the 3 rice types, with 50g carbohydrate content each week. Blood samples were collected before and at 15,30,60 and 120 minutes, after taking glucose and rice. At the end of the experiment, all subjects received all three kinds of rice and the GI was calculated for each rice as the ratio of the incremental area under the 3- hour glycemic response curve to rice, to the incremental area under the 3- hour glycemic response curve to sugar. Results: The glycemic indices of Sorna Pearl, Kasemin and Basmati were 52/2±5/1, 67/6±13 and 61/2±6/1 respectively, the GI of Sorna perl being lower than the others (p<0/05). Maximum changes of blood sugar for Sorna Perl, Kasemi and Basmati were 21/8±12, 27/4±6 and 31/7±5/9 mg/dl respectively. Conclusion: The results of this study indicate that in healthy of the 3 types of rice cnsumed subjects Sorna Perl had the lowest GI and GL.
