Glucose Variability in Patients With Type 1 Diabetes With a Sucrose-added Diet

BACKGROUND: The treatment with continuous glucose monitoring system (CGMS) offers improved glycemic control for patients with type 1 diabetes. However, patients with type 1 diabetes usually intake foods with sugar, even without hypoglycemic episodes, and the use of advanced carbohydrate counting method may increase the calories and carbohydrate intake. OBJECTIVE: To evaluate and compare the influence of sucrose-free diet or sucrose-added diet on glucose variability in patients with type 1 diabetes. METHODS: The study was a simple-blind, two-way crossover design in which patients with type 1 diabetes will receive a control diet (a diet with a little quantity of sugars) or test diet (with foods containing moderate quantity of sucrose in composition) during two-days each. During the intervention, all foods and drinks intake will have to be documented to allow quantitative estimation of dietary intake, to verify adherence to the diets. After one-week, each patient will return for download CGMS. PURPOSE: The research proposal adds knowledge about the glucose variability in patients with type 1 diabetes who use foods with sugar in theirs habitual dietary intake.
