Objective:To evaluate the influence of the changes in the dietary structure on the glycometabolism of the type 2 diabetic patients with increased postprandial blood glucose.Methods:60 type 2 diabetic patients with increased postprandial blood glucose in the endocrinology department,with no serious complication and normal hepatorenal function, were divided into vegetable group and Acarbose group randomly. The data were analyzed statisticaly with the help of SPSS19.0 software.Results:With two months’ treatment, the fasting plasma glucose (FPG),2h postprandial plasma glucose (2hPPG),and HbAlc of the patients of every group differ statisticaly(p<0.01), compared with the data from the same one colected before the treatment. But the FPG, 2hPPG and HbAlc of the patients of the two groups differ statisticaly,compared with the data colected after the two months’ treatment(p>0.05).Conclusion:Adding vegetables to meals can improve the glycometabolism of the type 2 diabetic patients with increased postprandial blood glucose.
