简要总结
The goal of this clinical study is to evaluate the effect of nutritional intervention program based on dietary products in the clinical treatment of newly diagnosed children with type 1 diabetes. The main question aims to answer is: whether high fiber diet can protect beta-cell function in children with newly onset type 1 diabetes.
Participants will take 12 weeks of high fiber diet intervention and beta-cell function and gut microbiota structure will be analyzed.
详细描述
The purpose of this project is to establish an early adjuvant treatment program for children with type 1 diabetes targeting gut microbiome, and to evaluate the clinical effect and safety of a dietary product to protect the beta-cell function of newly diagnosed type 1 diabetes children and improve blood sugar control.
Plan to adopt the parallel randomized controlled clinical trial method to select newly-diagnosed type 1 diabetes children, and randomly divide them into Usual care group and High fiber diet group at a ratio of 1:1. To comprehensively evaluate the clinical effect and long-term effect of a high fiber dietary intervention product, the changes of beta-cell function, glucose metabolism, and the structure and function of gut microbiota will be compared before and after treatment.

研究组 & 干预措施
High fiber intervention group
Participants in the high fiber intervention group take high fiber dietary products (28g dietary fiber per day) for 12 weeks, and at the same time, follow the doctor's advice to use subcutaneous insulin injection for treatment.
干预措施: Trimtab (Dietary Supplement)
Usual treatment group
Participants in the usual treatment group received routine diet education for diabetes and were treated with subcutaneous insulin injection according to the doctor's advice
