Effect of a sugar replacement on blood sugar levels in healthy adults

Effect of the Replacement of Glycaemic Carbohydrates With Galacto-Oligosaccharide (GOS) Supplementation on Postprandial Glycaemic Response in Healthy Adults

Not applicable Interventional University of Aberdeen · NCT06714552

What this trial studies

This study investigates how Oligomate®, a beta-galacto-oligosaccharide, affects blood sugar levels after meals in healthy adults. Participants will consume a beverage containing either Oligomate® or glucose, and their blood samples will be collected at various time points to measure glucose and insulin levels. The study is designed as a single-blind, randomized, controlled, cross-over trial, ensuring that each participant serves as their own control. The aim is to determine if this sugar replacement can lower postprandial hyperglycemia, potentially benefiting metabolic health.

Who should consider this trial

Good fit: Ideal candidates are healthy men and women aged 18 to 65 with a BMI between 18.5 and 29.9.

Not a fit: Patients with diabetes or any endocrine diseases, as well as those on medications affecting blood glucose levels, will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new dietary approach to help manage blood sugar levels and reduce the risk of metabolic diseases.

How similar studies have performed: Other studies have shown promise in using sugar replacements to manage blood glucose levels, suggesting this approach may be effective.
