Summary

The goal of this study is to determine the extent to which excess dietary simple sugars serve as a secondary mediating factor in Cystic fibrosis-related diabetes (CFRD) development. The main questions it aims to answer are:

* Whether conducting a randomized 2x2 factorial design that evaluates acute postprandial changes in glucose over 2 hours following ingestion of a mixed meal challenge that varies by glycemic index and consumption of a sugar-sweetened beverage is acceptable and feasible.
* What are the preliminary changes in postprandial hyperglycemia, islet cell function, and incretin response to a high or low Glycemic Index mixed meal tolerance test (MMTT) with and without Sugar-Sweetened Beverages (SSB) in adolescents and young adults with CF

Participants will be randomized to a mixed diet and blood will be drawn before and after the mixed meal challenge.

Conditions

Interventions

OTHER

Sugar Sweetened Beverages (SSB)

The following are considered SSBs: non-diet soft drinks/sodas, flavored juice drinks, sweetened tea, energy drinks, and electrolyte replacement drinks.

OTHER

Hi GI

The Glycemic Index of the high-GI meals will be at least 75

OTHER

Lo GI

The Glycemic Index of the low- -GI meals will not be higher than 55.
