Should fish be avoided during pregnancy because of its contaminants?

Updated on: Feb 1, 2016

No. Fish is an excellent source of omega-3, which is essential to the proper development of the baby. Although some fish contain significant amounts of contaminants, it is important during pregnancy and the years of fertility to choose fish with the most omega-3 and the fewer contaminants.

At the Montreal Diet Dispensary, it is recommended for pregnant women to eat two portions (150 g or 5 oz each) of fish per week. This recommendation can cover the basic needs of omega-3 for the health of women and the proper development of her baby.

However, some fish contain significant amounts of contaminants such as mercury, which may interfere with the optimal development of the baby. For this reason, some fish should be favored more than others.
