Low Glycemic Index for Gestational Diabetes

Gestational Diabetes Mellitus (GDM) incidence is increasing worldwide, and within Canada, the Atlantic provinces statistically have been found to have highest prevalence of diabetes. Increasing evidence supports the benefit of following a low glycaemic index (GI) diet in GDM and the Canadian Diabetes Guidelines recommends replacing high GI foods for low GI foods. Despite recommendation to adapt a low GI diet in GDM, there are limitations and barriers recognized to GI utility largely focused on knowledge translation. There is sufficient research to support a low GI diet in benefiting outcomes of GDM, therefore the GI in GDM Online trial will investigate the feasibility and effectiveness of a distance low GI education intervention, adapted from Diabetes Canada's GI materials, on producing a difference in average dietary GI between a group with the intervention and standard care.
