Summary

Glycaemic responses to carbohydrates ingested as fruit and vegetables may vary depending on factors inherent to the fruit or vegetable, and on the type of sugar. The aim of this project is to investigate the glycaemic responses to two new fruit and vegetable smoothies, and to establish the glycaemic index for each product relative to a glucose reference. Participants will undertake 4 postprandial tests with 2 different test drinks following best practice guidelines for glycaemic index testing. The test drinks (GREEN and RED) will be matched for carbohydrate to the glucose reference (CONTROL) which will be sampled two times. Fingerstick capillary blood sampling will measure glucose concentrations. These data will provide insight into how differing formulations can alter the glycaemic responses to fruit and vegetable drinks.
