Abstract: Objection: To evaluate the postprandial blood glucose responses to four kinds of cereals (red rice, black rice, millet and buckwheat). Method: Fourteen healthy volunteers took one kind of the four cereals as breakfast. White rice was served as the standard reference food, and each share of food contained 50g carbohydrate. Fasting and postprandial blood glucose 30、60、120、180min after meals were examined. Results: We set the glycemic index of white rice at 100,and then the glycemic index of the four tested cereals showed as follow: red rice 68.54±32.93, buckwheat 76.01±30.56, millet 94.18±26.83 and black rice 98.80±32.17. The glycemic index of red rice was statistically smaller than black rice and millet. Conclusion: Red rice and buckwheat are foods of smaller glycemic index.
