Can a vegetable smoothie keep blood sugar steady? a trial puts two recipes to the test
NCT ID NCT07729631
First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time
Summary
This study investigates how two different fruit and vegetable smoothies affect blood sugar levels in healthy adults aged 18 to 65. Participants will drink the smoothies and a glucose control drink on separate days, with finger-prick blood samples taken over two hours. The goal is to calculate each smoothie's glycaemic index, which measures how quickly a food raises blood sugar. The findings could help people understand which smoothie formulations have a gentler impact on blood sugar.
