You're standing in the grocery aisle, staring at a tin of flat fillets in olive oil, and honestly, you just want the salt. Pregnancy does that to you. One minute you're fine, and the next, you’d practically sell your soul for a Caesar salad or a slice of salty pizza. But then the panic sets in. You remember that vague warning about "mercury in fish" or "raw seafood," and suddenly, that tiny can of fish feels like a biological hazard.
So, can pregnant women eat anchovies without worrying?
Yes. Actually, it’s better than just "yes"—most doctors and nutritionists are basically begging you to eat them. While the world of pregnancy nutrition feels like a minefield of "don't touch this" and "boil that," anchovies are one of the few genuine superfoods that stay on the "safe" list. They are tiny. They are salty. And they are packed with the stuff your baby’s brain is currently demanding.
The Mercury Myth and Why Size Matters
Most people get scared of fish during pregnancy because of methylmercury. It's a valid fear. High levels of mercury can mess with a developing baby’s nervous system. But here is the thing about the ocean's food chain: it’s a game of accumulation.
Big fish like Shark, Swordfish, and King Mackerel live for a long time. They eat smaller fish, and the mercury builds up in their tissues over years. Anchovies are at the bottom of the ladder. They eat plankton, they grow fast, and they don't live long enough to soak up the industrial junk we've dumped into the water. According to the FDA and the EPA, anchovies fall squarely into the "Best Choices" category.
You’d have to eat a truly staggering amount of these little guys to reach concerning mercury levels. We’re talking amounts that would make your sodium levels a much bigger problem than the mercury ever could be.
Brain Power in a Tiny Tin
When we talk about fetal development, two letters dominate the conversation: DHA.

Docosahexaenoic acid is an omega-3 fatty acid. It’s the literal building block of your baby’s retinas and cerebral cortex. During the third trimester, the baby’s brain is basically a sponge for DHA, pulling it from your body at a rapid rate. If you aren't replacing it, you might feel that "pregnancy brain" fog even harder.
Anchovies are swimming in omega-3s.
A single serving of anchovies can provide upwards of 900 milligrams of EPA and DHA combined. For context, many prenatal vitamins only offer about 200mg. You’re getting the real deal, bioavailable version that your body recognizes and uses immediately.
Then there’s the calcium. If you’re eating the whole fish—the kind you find in jars or tins where the bones are softened—you’re getting a massive hit of calcium. This is huge because if you don’t consume enough calcium, your baby will literally leach it from your own bones and teeth. It sounds like a horror movie, but it's just biology. Anchovies help keep your skeleton intact while your baby builds theirs.
What About the Salt?
Here is the catch. Anchovies are salty. Like, really salty.
Most canned anchovies are cured in salt to preserve them. If you’re struggling with gestational hypertension or if your ankles look like puffed-up marshmallows by 4 PM, you need to be careful. High sodium intake can trigger water retention and put extra pressure on your kidneys, which are already working overtime.

One trick? Rinse them.
Pop the fillets out of the tin and run them under cool water for a few seconds. You’ll wash away a significant portion of the surface salt without losing the healthy fats tucked inside the meat. Or, look for anchovies packed in water or "low sodium" versions, though those are harder to find and, frankly, don't taste quite as good.
The Raw vs. Cured Debate
I get this question a lot: "Are they raw?"
Standard tin anchovies are "cured." They are heavily salted and aged for months. This process isn't "cooking" with heat, but it effectively kills off most of the nasty bacteria like Listeria that keep pregnant women up at night.
However, you should steer clear of "Boquerones."
These are white anchovies usually found in the refrigerated section, marinated in vinegar and oil. They aren't heat-treated or heavily salt-cured in the same way. While the vinegar acidity helps, they carry a slightly higher risk of containing Anisakis parasites. If you’re pregnant, stick to the shelf-stable tins or the jars. The high-heat canning process used for the shelf-stable stuff makes them incredibly safe from a microbiological standpoint.

Real World Ways to Eat Them
Don't feel like you have to eat them straight out of the can like a sea lion.
- The "Umami Bomb" Pasta: Sauté garlic and red pepper flakes in olive oil. Throw in three or four anchovy fillets and stir them until they literally melt. They disappear into the oil. Toss in some pasta and lemon juice. You won't taste "fish," you'll just taste "delicious."
- Caesar Dressing: Most authentic Caesar dressings use anchovy paste. It’s safe. It’s tasty. Just ensure the dressing doesn't use raw egg yolks (many commercial ones use pasteurized eggs, which are fine).
- Pizza Topping: Just put them on after the bake if you want the full nutrient profile, or bake them on if you want that salty, charred flavor.
Vitamins You Didn't Know You Needed
Beyond the fats, these tiny fish are loaded with Selenium.
Selenium is a trace mineral that acts like a bodyguard for your cells. Some studies suggest it might even help protect against the toxic effects of whatever tiny amount of mercury is present in fish. It’s nature’s way of balancing the scales. You also get a decent dose of Vitamin B12 and Iron, both of which are critical because your blood volume increases by about 50% during pregnancy. Anemia is no joke, and every little bit of heme iron helps.
A Note on Sustainability and Sourcing
If you care about the planet your kid is going to inherit, anchovies are a win here, too.
Unlike salmon farming, which has its own set of environmental headaches, or tuna fishing, which often has high "bycatch" rates (meaning dolphins and turtles get hurt), anchovy fisheries are generally well-managed. They reproduce fast. They are resilient. Look for the MSC (Marine Stewardship Council) blue label on the tin if you want to be 100% sure you're buying from a sustainable stock.
Final Verdict
So, can pregnant women eat anchovies?
Absolutely. Unless your doctor has specifically told you to move to a zero-sodium diet, these fish are a nutritional powerhouse. They are low-mercury, high-DHA, and packed with calcium. They help with brain development, protect your bones, and satisfy that weird salt craving all at once.
Actionable Steps for the Cravings
- Check the Label: Buy shelf-stable tins or jars, not the "fresh" marinated white anchovies in the fridge section.
- Rinse for Relief: If you’re worried about bloating or blood pressure, rinse the fillets under cold water for 30 seconds before eating.
- Start Small: If you’re worried about the "fishy" taste, mash one single fillet into a pasta sauce or a stew. It adds depth without making the whole house smell like a wharf.
- Frequency Matters: Aim for 2 portions of oily fish a week. A portion is roughly 140g, so a small tin of anchovies gets you a good chunk of the way there.
- Hydrate: After a salty snack, double your water intake for the next hour to help your kidneys flush the extra sodium.
Focus on the shelf-stable options and enjoy the boost to your baby's brain health. You're doing a great job, and honestly, if an anchovy pizza is what gets you through the day, go for it.
