Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
