Abstract:
Gestational diabetes mellitus (GDM) is an escalating public health concern due to its
association with short- and long-term adverse maternal and child health outcomes. Dysbiosis of
microbiota within the gastrointestinal tract has been linked to the development of GDM. Modification
of microbiota dysbiosis through dietary adjustments has attracted considerable attention as adjunct
strategies to improve metabolic disease. Diets high in fibre and polyphenol content are associated
with increased gut microbiota alpha diversity, reduced inflammation and oxidative processes and
improved intestinal barrier function. This review explores the potential of fibre and polyphenol
supplementation to prevent GDM by investigating their impact on gut microbiota composition
and function.
