To most pregnant women, it will be clear that there is no place for alcohol during pregnancy

But if there I still a tendency to drink “something”,then extra choline should be taken. Choline is found mainly in eggs, therefore I highly recommend pregnant women to eat regularly an egg.

Nuts, meat, fish etc do all contain but some eggs are important. Vegans may be more prone to a lack of choline and may have to take supplements

Folic acid is known to reduce the risk of neural tube defects (NTDs). Even so, NTDs continue to occur despite individual supplementation or population fortification with folic acid. We investigated other nutrients related to one-carbon metabolism that may affect NTD risk.
