Glycemic Index of Sweet Corn
A study testing Sweet corn and Glucose Tolerance Drink in people with Glycemic Index, run by University of Florida at 2 sites in United States.
Trial summary
Processing sweet corn may impact digestibility and, therefore, glycemic response following consumption. The primary aim of this study is to assess the glycemic index of various sweet corn products and varieties. An exploratory aim is to assess hunger/satiety scores following sweet corn intake.

About this study
Official title: Determination of the Glycemic Index of Differently Processed Sweet Corn
Processing sweet corn may impact digestibility and, therefore, glycemic response following consumption. The primary aim of this study is to assess the glycemic index of various sweet corn products and varieties. An exploratory aim is to assess hunger/satiety scores following sweet corn intake.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
iAUC (time frame: From enrollment to the end of 5 weeks.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Sep 2026.
