Summary

This trial aims to see how consuming excess simple sugars affects the development of diabetes in people with Cystic fibrosis. They will give participants different meals and drinks to see how it affects their blood sugar

Who is the study for?
This study is for adolescents and young adults with Cystic Fibrosis. It's designed to see if different types of sugar in meals affect their blood sugar levels and insulin function. Participants will be given meals with high or low glycemic index sugars, some including sugary drinks.Check my eligibility
What is being tested?
The trial tests how the body reacts to meals that have sugars which are absorbed at different rates (high vs low glycemic index) and whether adding a sugary drink makes a difference. Blood samples before and after eating measure changes in glucose, insulin function, and hormones related to digestion.See study design
What are the potential side effects?
Since this trial involves dietary intake rather than medication, side effects may include discomfort from blood draws or potential short-term changes in blood sugar levels due to the meal challenges.

Trial Design

4Treatment groups
Experimental Treatment
Group I: SSB+ HI- GIExperimental Treatment2 Interventions
All standardized mixed meal challenges will be similar in calories (kcal) and percent of calories from carbohydrates (45%), protein (15%), and fat (40%). Each meal will provide 1/3rd of the subject's estimated kcal needs per current CF nutrition guidelines
Group II: SSB + LO- GIExperimental Treatment2 Interventions
All standardized mixed meal challenges will be similar in calories (kcal) and percent of calories from carbohydrates (45%), protein (15%), and fat (40%). Each meal will provide 1/3rd of the subject's estimated kcal needs per current CF nutrition guidelines
Group III: NSSB+ LO- GIExperimental Treatment1 Intervention
All standardized mixed meal challenges will be similar in calories (kcal) and percent of calories from carbohydrates (45%), protein (15%), and fat (40%). Each meal will provide 1/3rd of the subject's estimated kcal needs per current CF nutrition guidelines
Group IV: NSSB+ HI- GIExperimental Treatment1 Intervention
All standardized mixed meal challenges will be similar in calories (kcal) and percent of calories from carbohydrates (45%), protein (15%), and fat (40%). Each meal will provide 1/3rd of the subject's estimated kcal needs per current CF nutrition guidelines
