Can I eat fish while breastfeeding?

In many cases, yes. Fish can be part of a healthy breastfeeding diet because it provides protein and important nutrients, including omega-3 fats. The key is choosing lower-mercury options more often and limiting or avoiding fish known to be high in mercury. If you recently ate fish and feel unsure, the most helpful next step is to look at the type of fish, how much you ate, and how often you usually eat it.

Low-mercury fish breastfeeding moms often choose

Salmon

A popular lower-mercury choice that provides protein and omega-3s. If you’re asking is salmon safe while breastfeeding, it is commonly considered one of the better options.

Shrimp

Generally lower in mercury and often included among safer seafood choices during breastfeeding when prepared and stored properly.

Tilapia or cod

These are commonly chosen as milder, lower-mercury fish options for parents who want to keep eating seafood while breastfeeding.

High-mercury fish while breastfeeding: options to avoid or limit

Swordfish

Known for higher mercury levels and generally best avoided while breastfeeding.

Shark

Typically listed among high-mercury fish and not a good routine choice for breastfeeding parents.

King mackerel

Another fish commonly flagged for higher mercury content, making lower-mercury alternatives a better fit.

How much fish can I eat while breastfeeding?

The answer depends on the type of fish and your usual eating pattern. Lower-mercury fish can often fit into your meals regularly, while higher-mercury fish should be avoided or kept very limited. If your concern is tuna while breastfeeding and mercury exposure, the type of tuna matters, since some kinds are lower in mercury than others. Looking at your weekly seafood habits gives a more accurate picture than focusing on one meal alone.

What to consider if you already ate fish and feel worried

What kind of fish it was

Mercury levels vary a lot by species, so the name of the fish matters more than simply whether it was seafood.

How often you eat it

One meal usually raises different questions than a repeated pattern of eating higher-mercury fish over time.

How much you ate

Portion size can help put exposure into context and guide what to do next with future choices.
