Study to Examine Glycaemic Responses to the Ingestion of Fruit Juices and Smoothies Using Different Measurement Methodologies.

Not applicable Interventional University of Bath · NCT06898840

This study tests how different fruit drinks affect blood sugar levels in adults aged 18-65 to see which ones are better for managing glucose responses.

What this trial studies

This project investigates how different commercially available fruit drinks affect glycaemic responses in participants. Participants aged 18-65 with a BMI of 18-30 will consume eight test drinks, including five fruit drinks, and their blood glucose levels will be measured using both fingerstick sampling and continuous glucose monitors. The study aims to establish the glycaemic index of each drink relative to a glucose reference, while also considering factors like sample type and individual characteristics. Subjective appetite sensations will also be recorded during the testing.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18-65 with a body mass index between 18 and 30.

Not a fit: Patients with diabetes or conditions affecting glucose metabolism will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the glycaemic impact of fruit drinks, helping patients make informed dietary choices.

How similar studies have performed: While there have been studies on glycaemic responses to various foods, this specific approach to measuring fruit drinks is relatively novel.
