| Summary: | Gestational Diabetes Mellitus develops in 3.7-18% of Canadian women, and can cause serious maternal-fetal complications. Low-GI foods have been shown to increase β-cell function in subjects with impaired glucose tolerance. Theoretically, this effect should improve glucose tolerance and reduce the risk of gestational hyperglycemia. Thus, we aimed to explore the effects of a low-GI diet on glucose challenge test (GCT) results in women at risk for GDM. Women were randomized to receive education during pregnancy focused on incorporation of low- or medium- to high-GI foods. Key foods were provided to assist compliance. Information was obtained from medical records and questionnaires. Ninety-four (94) women completed the study. After adjustment for confounding variables, there was no significant difference in GCT values between intervention groups. Results suggest that low-GI foods do not affect blood glucose control during pregnancy. |
