ClinConnect Summary

This clinical trial is looking at how different types of sweet corn and how they are processed can affect how our bodies digest them and respond in terms of blood sugar levels. The main goal is to find out the glycemic index, which is a measure of how quickly foods raise blood sugar after eating. Additionally, the study will also explore how eating sweet corn affects feelings of hunger and fullness.

To be eligible for this trial, participants should be between the ages of 65 and 75, be able to read and understand English, and be willing to eat specific amounts of glucose and sweet corn over several mornings. Participants will also need to provide small blood samples using a fingerstick, which is a quick and simple way to check blood sugar levels. However, individuals with certain health conditions that affect blood sugar, such as diabetes or metabolic syndrome, or those who are pregnant, cannot take part in this study. If you join, you can expect to help researchers learn more about sweet corn and its effects on our health!
