Summary

This study explores how different amounts of carbohydrates and a fiber supplement called inulin-FOS affect blood sugar control in adults with type 1 diabetes. Participants will try three two-week diets: one with 30% carbs, one with 50-55% carbs, and one with 50-55% carbs plus inulin-FOS. Blood sugar is tracked continuously, and the goal is to find which approach works best for managing glucose levels.

Active substance: inulin and fructooligosaccharide (FOS) dietary supplement
What this could lead to: If successful, this could help identify an optimal diet plan for better blood sugar management in type 1 diabetes.
