Can dietary phytophenols improve pregnancy outcomes?
Preterm birth and GDM are seemingly disparate conditions but linked by common pathways in their pathogenesis. They affect up to 20% of all pregnancies but have an impact that extends well beyond pregnancy and childbirth, with the potential for lifelong morbidity or mortality for both mother and baby. Despite the enormous health-impact of both these conditions, little progress has been made with interventions aimed at prevention. Rates of preterm birth remain static, whilst GDM is increasing in parallel with the obesity epidemic. A safe and effective intervention that can reduce the burden of preterm birth and GDM would be a major public health initiative.
There is increasing volume and quality of evidence that high fruit and vegetable intake in pregnancy is associated with a decreased risk of adverse pregnancy outcomes . For example, consumption of a diet rich in fruits, vegetables and whole grains (Dietary Approaches to Stop Hypertension (DASH) diet) in pregnant women with GDM had beneficial effects on their metabolic profile. Many of these beneficial properties have been attributed to the potent anti-inflammatory properties of phytophenols. There are, however, no studies that have assessed dietary phytophenols in preterm birth or GDM.
In this project, in vitro and in vivo studies will be used to test the hypothesis that dietary phytophenols can delay preterm birth and prevent the development of GDM, and improve fetal outcome in both these conditions.
