Study authors say the findings raise the exciting possibility that choline may be used therapeutically in cases where excess maternal stress from anxiety, depression or other prenatal conditions might make the fetal HPA axis more reactive and more likely to release greater-than-expected amounts of cortisol.
While more research is needed, Caudill says that her message to pregnant women would be to consume a diet that includes choline rich foods such as eggs, lean meat, beans and cruciferous vegetables like broccoli. For women who limit their consumption of animal products, which are richer sources of choline than plant foods, she adds that supplemental choline may be warranted as choline is generally absent in prenatal vitamin supplements.
"One day we might prescribe choline in the same way we prescribe folate to all pregnant women," notes Pressman, the James R. Woods Professor in the Department of Obstetrics and Gynecology. "It is cheap and has virtually no side effects at the doses provided in this study. In the future, we could use choline to do even more good than we are doing right now."
