High egg consumption may increase GDM risk

WOMEN eating more than one egg a day may nearly double their risk of gestational diabetes mellitus (GDM), researchers warn.

Although high egg consumption has been associated with an increased risk of type 2 diabetes, few studies have assessed the association of high cholesterol from eggs with GDM risk.

Researchers combined data from a case-control and a prospective cohort study, involving a total 3600 women and designed to examine dietary risk factors for adverse pregnancy outcomes and the epidemiology of pre-eclampsia, respectively.

They determined women eating more than seven eggs per week periconceptually and in early pregnancy had an overall 1.77-fold increased risk of GDM compared with women consuming few eggs while pregnant.The increased risk was independent of other risk factors for GDM. 

Women consuming two or three eggs per week had little increased risk, said the authors, who included perinatal experts from Sweden and the US
