This prospective, randomized, controlled, clinical trial, compared the effect of a Mediterranean Diet supplemented with extra-virgin olive oil and pistachios (MedDiet) to a standard low fat diet (Control) on the incidence of gestational diabetes.
Women on the MedDiet had a lower incidence of GDM, lower rates of GDM that required insulin treatment, lower premature births, emergency CS and small for gestational age newborns than those on the control diet.
This study shows that a Mediterranean diet supplemented with extra-virgin olive oil and pistachios early in gestation reduces the incidence of gestational diabetes and improves several maternal and neonatal outcomes.
