Brief Summary

The gut microbiome is increasingly recognized as a contributor to disease states. In type 1 diabetes, alterations in gut microbiota may be linked to changes in intestinal permeability, inflammation and insulin resistance. Prebiotic fiber is a dietary supplement that alters gut microbiota and could potentially improve insulin sensitivity in children with type 1 diabetes. This pilot study aims to determine the feasibility of a 12-week dietary intervention with prebiotic fiber in children with type 1 diabetes. The investigators hypothesize that consumption of prebiotic fiber will alter gut microbiota and intestinal permeability, leading to improved glycemic control. Prebiotic fiber is a potentially novel, inexpensive, low-risk treatment addition for type 1 diabetes that may improve glycemic control by changes in gut microbiota, gut permeability and inflammation.
