Diabetes Clinical Trial
Official title:
An Exploratory Study on the Application of Continuous Glucose Monitoring System in the Measurement of Individual Glycemic Index After Eating Different Diets
The glycemic index (GI) is used to evaluate the level of elevated blood sugar immediately after carbohydrate intake and is a classified indicator of the glycemic potential of carbohydrate-containing test foods relative to reference foods. At present, more and more clinical studies have proved that a low-GI diet is beneficial to health, and can improve blood glucose control, weight and blood lipid levels in patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM). GI is currently widely used to provide guidance on food choices for people with diabetes. However, there are great differences in blood glucose response among different individuals after eating the same food, which is related to a variety of factors,including individual gastrointestinal digestion and absorption rate,islet function,insulin resistance and region. A large number of foreign studies suggest that race affects the determination of GI, but different regions of our country have different dietary culture and different ability to digest and absorb different foods. Therefore, the traditional GI reference value does not necessarily fully reflect the blood glucose response of diabetic patients after eating a food. In this study, continuous blood glucose monitoring was carried out through CGM to monitor the overall fluctuation level of blood glucose, the time to peak and the range of blood glucose fluctuation after eating specific foods, and to obtain individual GI, after eating different diets to guide the future diet.
