One of the reasons I don’t like how we talk about fish intake during pregnancy- we scare moms away from it.
DHA is one of the main omega 3 fatty acids in fatty fish like salmon.
The conventional recommendation is to limit fish intake to 12oz per week of low mercury fish and limit tuna to 6 oz per week. However, there is no evidence that going above 12 oz is harmful but lots of evidence that below 12 oz is harmful to mom and baby. Increasing likelihood of things like postpartum depression is one of those potential harms of not consuming enough fish.
If you’re not eating fatty fish like salmon, herring, sardines, fish roe, atlantic or alaskan mackerel (NOT king) ~3 times a week, you likely would benefit from supplementing with fish oil or cod liver oil during pregnancy and postpartum.
Just avoid the high mercury fish: swordfish, king mackerel, tilefish, pilot whale, and shark.
