Brief Summary

The trial was a multicenter, randomized, double-blind, placebo-controlled, parallel-controlled, exploratory clinical study.Through the intervention of soluble dietary fiber in the pre-type 2 diabetic population, the change of blood glucose spectrum before and after intervention can show the effect of this intervention on the outcome, and further elucidate the effect of soluble dietary fiber intervention on the level of insulin resistance and its effect on outcome. Helps to prevent the more scientific and effective prevention of type 2 diabetes from pre-diabetes. Subjects who met the criteria were randomly divided into the experimental group and the control group, after 24 weeks of intervention, the incidence of blood sugar reversion to normal was main observed.The main purpose of this study was to investigate the effect of soluble dietary fiber treatment regimens on the conversion rate of pre-type 2 diabetes (converted to normal blood glucose, type 2 diabetes, or stable in the stage of impaired glucose tolerance). The secondary objective was to study the improvement of insulin resistance and changes in intestinal flora after intervention.

Detailed Description

The soluble dietary fiber (NIUCHANG®) and placebo used in the trial were exclusively produced by Inuling (Beijing) Technology Co., Ltd. and provided free of charge. During the treatment period, the treatment group was given oral "NIUCHANG®" (once 15g,once a day)and the control group was given oral placebo (once15 g, once a day) for 24 weeks. The test was performed for 12 weeks as a course of treatment。At the end of one course of treatment, if the glucose tolerance was changed to normal or the blood glucose was stable in the pre-diabetes phase, the original dose was maintained and continued for 12 weeks. At 24 weeks, patients with normal blood glucose and glucose tolerance tests were followed up for 48 weeks. At the end of one course of treatment, if the blood glucose progresses to the stage of diabetes, the test is withdrawn and treated according to clinical routine.
