Eating fish during pregnancy is safe and beneficial if you choose low-mercury, properly cooked options in moderation.
Understanding the Importance of Fish During Pregnancy
Fish is a nutritional powerhouse, packed with essential nutrients that support both maternal health and fetal development. Omega-3 fatty acids, especially DHA (docosahexaenoic acid), found in many fish varieties, are crucial for the baby’s brain and eye development. Protein from fish also helps build tissues and organs, while vitamins like D and B12 contribute to bone health and energy metabolism.
However, pregnancy introduces a layer of caution due to potential contaminants in seafood—primarily mercury. Mercury exposure can adversely affect the developing nervous system of the fetus. This is why pregnant women often question, “When You’re Pregnant – Can You Eat Fish?” The answer hinges on selecting the right types of fish and adhering to recommended consumption limits.
Mercury: The Main Concern in Fish Consumption During Pregnancy
Mercury is a naturally occurring element that can accumulate in water bodies, entering aquatic food chains. Larger predatory fish tend to have higher mercury concentrations due to bioaccumulation. When consumed excessively by pregnant women, mercury can cross the placenta, potentially causing neurological damage to the fetus.
Not all fish contain dangerous mercury levels. Some species are low in mercury and safe for regular consumption during pregnancy. Understanding mercury content helps expectant mothers make informed choices without missing out on vital nutrients.
High-Mercury Fish to Avoid
Pregnant women should avoid fish known for high mercury levels entirely. These include:
- Shark
- Swordfish
- King Mackerel
- Tilefish (Gulf of Mexico)
- Bigeye Tuna
These species accumulate mercury at levels that pose a risk during fetal development. Steering clear of these options eliminates unnecessary exposure.
Low-Mercury Fish Safe for Pregnancy
Many common fish are low in mercury and rich in beneficial nutrients:
- Salmon
- Shrimp
- Canned Light Tuna (in moderation)
- Pollock
- Catfish
- Sardines
- Trout
These options provide valuable omega-3s without significant mercury risk, making them ideal choices during pregnancy.
Nutritional Benefits of Eating Fish While Pregnant
Fish delivers several nutrients critical for pregnancy beyond omega-3 fatty acids:
- Protein: Supports fetal tissue growth and repair.
- Iodine: Essential for thyroid function and brain development.
- Vitamin D: Helps regulate calcium absorption, supporting bone development.
- B Vitamins: Aid energy production and red blood cell formation.
Incorporating fish into your diet can improve pregnancy outcomes like higher birth weight and reduced risk of preterm birth. Studies also link maternal omega-3 intake with improved cognitive function in children later on.
How Much Fish Can You Safely Eat While Pregnant?
Balancing benefits against risks means sticking to recommended serving sizes:
The U.S. Food and Drug Administration (FDA) advises pregnant women to eat 8–12 ounces (about two to three servings) per week of low-mercury fish.
Exceeding this amount may increase exposure risks without additional benefits. Portion control ensures you get enough nutrients while minimizing any potential harm.

Frequently Asked Questions
When You’re Pregnant – Can You Eat Fish Safely?
Yes, you can eat fish safely during pregnancy by choosing low-mercury varieties and consuming them in moderation. Properly cooked fish provides essential nutrients like omega-3 fatty acids and protein that support fetal development and maternal health.
When You’re Pregnant – Can You Eat Fish High in Mercury?
No, pregnant women should avoid fish high in mercury such as shark, swordfish, and king mackerel. Mercury exposure can harm the developing nervous system of the fetus, so steering clear of these species is important for a healthy pregnancy.
When You’re Pregnant – Can You Eat Fish Like Salmon or Shrimp?
Yes, salmon and shrimp are considered low-mercury fish and safe to eat during pregnancy. They are rich in omega-3 fatty acids, which are crucial for your baby’s brain and eye development, making them excellent choices for expectant mothers.
When You’re Pregnant – Can You Eat Canned Tuna?
Canned light tuna can be eaten in moderation during pregnancy. It is lower in mercury compared to other types of tuna but should still be limited to avoid excessive mercury intake while benefiting from its protein and nutrient content.
When You’re Pregnant – Can You Eat Fish Every Day?
It’s best not to eat fish every day while pregnant. Moderation is key to balancing nutrient benefits with mercury risks. Aim for 2-3 servings per week of low-mercury fish to support your baby’s growth without overexposure to contaminants.
The Role of Cooking Methods for Safe Fish Consumption During Pregnancy
Proper preparation matters just as much as choosing the right fish type. Raw or undercooked seafood can harbor bacteria or parasites harmful during pregnancy when immunity is lowered.
Pregnant women should always:
- Avoid raw fish dishes: Sushi, sashimi, ceviche, or any uncooked seafood carry infection risks.
- Cook thoroughly: Fish should reach an internal temperature of at least 145°F (63°C).
- Avoid smoked or refrigerated seafood: Unless it’s cooked afterward, these products may contain listeria bacteria dangerous for pregnancy.
- Select fresh or properly frozen fish: Freshness reduces bacterial contamination chances.
- Avoid cross-contamination: Use separate utensils and cutting boards when handling raw seafood.
- Bake, grill or steam: Healthy cooking methods that preserve nutrients without adding unhealthy fats.
- Avoid frying excessively: Deep-fried fish may add unhealthy fats and calories which are best limited during pregnancy.
- If eating canned fish: Check labels for sodium content as excessive salt intake should be avoided during pregnancy.
- If unsure about local fish safety advisories: Consult local health departments especially if consuming freshwater catch from lakes or rivers due to pollution concerns.
- If allergic history exists: Discuss with your healthcare provider before including new types of seafood in your diet during pregnancy.
- If eating shellfish like shrimp or crab: Ensure they are fully cooked as shellfish also pose infection risks if raw or undercooked.
- If consuming canned tuna regularly: Limit albacore tuna intake due to moderate mercury levels but canned light tuna remains safer in moderation.
- If including omega-3 supplements derived from fish oil: Choose purified products free from heavy metals verified by third-party testing.
- If you experience any adverse symptoms after eating fish such as stomach upset or allergic reactions: Seek medical advice promptly.
- If you want variety in your diet while staying safe: Add plant-based omega-3 sources like flaxseed or walnuts alongside safe seafood options.
- If you’re vegetarian or vegan: You can obtain essential fatty acids through algae-based DHA supplements approved for pregnancy.
- If you’re concerned about sustainability while pregnant: Select eco-friendly certified seafood brands that also meet safety standards.
- If you’re monitoring weight gain: Certain lean fish varieties can provide protein without excess calories.
- If you want easy recipe ideas: Baked salmon with herbs or grilled trout with lemon offers simple nutritious meals.
- If you’re worried about taste preferences: Tuna salad made with light mayo offers a mild flavor accepted by many pregnant palates.
- If you want convenience: Canned sardines packed in water provide quick nutrient boosts without prep time.
- If you need guidance on portion sizes: A deck-of-cards sized piece equals approximately three ounces per serving.
Navigating Myths About Eating Fish During Pregnancy
Despite clear guidelines from health authorities worldwide supporting moderate consumption of safe fish types during pregnancy, myths persist that all seafood is unsafe. This misconception may lead some expecting mothers to avoid fish altogether—missing out on key nutrients vital for fetal growth.
Here’s why these myths don’t hold up:
- The fear that all mercury exposure is equally harmful ignores differences between high-mercury predatory species and low-mercury common choices like salmon or shrimp.
- The idea that cooking destroys nutritional benefits is false—properly cooked fish retains omega-3 fatty acids better than overcooked meat alternatives.
- The belief that canned tuna is always unsafe overlooks distinctions between canned light tuna (low mercury) versus albacore tuna (moderate mercury), allowing informed moderation instead of total avoidance.
- The notion that only supplements provide DHA ignores natural dietary sources proven effective when consumed safely during pregnancy.</LI>
