ClinConnect Summary

This clinical trial is studying how different fruit drinks affect blood sugar levels, which is known as the glycaemic response. Researchers want to understand how the type of fruit and the sugars in these drinks can change the way our bodies respond to them. Participants will taste eight different drinks, including five types of fruit juices, and their blood sugar levels will be measured using a fingerstick test and a continuous glucose monitor. This will help determine how each drink compares to a standard glucose drink.

To join the study, participants need to be between 18 and 65 years old, with a healthy body weight. However, people with diabetes, certain health conditions, or those who are pregnant or breastfeeding cannot participate. Those who take part will help researchers learn more about how different fruit drinks can affect blood sugar, which could provide valuable information for future dietary recommendations.
