Can You Eat Canned Fish When Pregnant?


Sharing is Caring


During pregnancy, it’s important to be mindful of what you eat, as certain foods can pose risks to the health of the mother and the growing baby. Fish is a great source of protein and omega-3 fatty acids, which are essential nutrients for a healthy pregnancy. However, not all types of fish are safe to consume during pregnancy, including canned fish. In this article, we’ll explore whether it’s safe to eat canned fish when pregnant and what types of fish to avoid.

While canned fish may seem like a convenient and healthy option, there are some concerns regarding its safety during pregnancy. One of the main concerns is the potential for mercury contamination, which can harm the developing nervous system of the fetus. However, not all types of fish contain high levels of mercury, and there are safe ways to consume canned fish during pregnancy.

If you’re wondering whether canned fish is a safe and healthy choice during pregnancy, keep reading to learn about the benefits of eating fish during pregnancy, the types of fish to avoid, and how to prepare canned fish in a healthy and safe way.

What are the benefits of eating fish during pregnancy?

Omega-3 fatty acids are crucial for a baby’s brain and eye development, and fish is an excellent source of them. Protein is another critical nutrient that helps build the baby’s bones and muscles, and fish is one of the best sources of lean protein. In addition, vitamin D is necessary for the baby’s bone health and is found in oily fish such as salmon and mackerel. Eating fish during pregnancy can also help reduce the risk of preterm birth and low birth weight, which can lead to health problems for the baby.

However, not all fish are created equal. Some contain high levels of mercury, which can be harmful to the baby’s nervous system. That’s why it’s essential to choose fish that are low in mercury but still provide all the essential nutrients that are beneficial during pregnancy.

In summary, eating fish during pregnancy can provide numerous health benefits for both the mother and the baby. However, it’s crucial to be aware of which types of fish are safe to consume and how much you should be eating to avoid any potential risks.

What are the benefits of eating fish during pregnancy?

Good for Baby’s Brain Development

One of the most important benefits of eating fish during pregnancy is its positive effect on the baby’s brain development. Fish is a rich source of omega-3 fatty acids, especially DHA, which is essential for the growth and development of the baby’s brain and nervous system.

The American Pregnancy Association recommends that pregnant women consume at least 8-12 ounces of fish per week to ensure an adequate intake of DHA and other important nutrients. Some of the best fish sources of DHA include salmon, mackerel, and sardines.

Studies have shown that children whose mothers consumed fish during pregnancy had higher cognitive function, better communication and social skills, and fewer behavioral problems compared to children of mothers who did not consume fish. Therefore, including fish in your diet during pregnancy may have long-lasting benefits for your child’s brain development.

Fish is known for being a great source of omega-3 fatty acids, which are important for fetal brain and eye development. The American Pregnancy Association recommends that pregnant women consume at least two servings of low-mercury fish per week to obtain these benefits. Omega-3s have also been linked to reducing the risk of preterm labor and postpartum depression.

Some types of fish, such as salmon and sardines, are particularly high in omega-3s. However, it’s important to note that the amount of omega-3s in canned fish can vary depending on the type and brand. To ensure that you’re getting a good amount, look for canned fish that is labeled as “wild caught” and packed in olive oil, water, or its own juices.

If you’re not a fan of fish, you can still get omega-3s from other sources such as chia seeds, flaxseeds, and walnuts. However, the omega-3s found in these plant-based sources are in the form of alpha-linolenic acid (ALA), which the body needs to convert to the more beneficial forms of omega-3s found in fish.

What types of fish should you avoid during pregnancy?

If you are pregnant, you should be aware that certain types of fish can be harmful to your developing baby due to their high levels of mercury. Mercury is a toxic heavy metal that can cause neurological damage in developing fetuses and young children. The following fish should be avoided during pregnancy:

Shark: This large predatory fish is high in mercury and should be avoided during pregnancy.

Swordfish: This is another predatory fish with high levels of mercury, so it’s best to avoid it during pregnancy.

King Mackerel: This fish is also high in mercury, so it’s best to avoid it during pregnancy.

Tuna: While it’s okay to eat some types of tuna in moderation during pregnancy, you should avoid eating bigeye tuna and limit your consumption of albacore tuna to no more than 6 ounces per week.

High Mercury Fish

Swordfish: Swordfish contains the highest amount of mercury, making it one of the most dangerous fish for pregnant women.

King Mackerel: King Mackerel contains very high levels of mercury and should be avoided during pregnancy.

Shark: Shark is a high mercury fish that should be avoided during pregnancy.

Other high mercury fish that should be avoided include bigeye tuna, marlin, orange roughy, and tilefish.

Raw or Undercooked Fish

Bacterial Infections: Raw or undercooked fish may contain harmful bacteria that can cause food poisoning, which can be particularly dangerous during pregnancy. These bacteria include Salmonella, Listeria, and Vibrio, all of which can cause severe illness.

Parasites: Raw or undercooked fish can also contain parasites such as tapeworms, which can be harmful to both the mother and the developing fetus. These parasites can cause infection, malnutrition, and even miscarriage or stillbirth in severe cases.

Mercury: Some types of fish, particularly predatory fish, may contain high levels of mercury. When consumed in large amounts, mercury can harm the developing nervous system of the fetus. Raw or undercooked fish can also contain high levels of mercury, so it’s important to avoid these types of fish during pregnancy.

Cooking Recommendations: To avoid the risks associated with raw or undercooked fish, it’s important to cook all fish thoroughly before consuming it. Fish should be cooked to an internal temperature of at least 145ยฐF (63ยฐC) and should be opaque and flaky when tested with a fork. It’s also important to avoid cross-contamination by using separate cutting boards, utensils, and dishes for raw and cooked fish.

Farmed Fish

Farmed fish are raised in crowded conditions, making them more susceptible to disease, parasites, and bacteria. To counter these problems, farmers often use antibiotics and other chemicals, which can end up in the fish that we eat. The nutritional value of farmed fish may also be lower compared to wild-caught fish.

Some farmed fish, like tilapia and catfish, may have higher levels of unhealthy omega-6 fatty acids and lower levels of healthy omega-3 fatty acids, which can increase inflammation in the body. In addition, farmed fish may be fed a diet that includes genetically modified organisms (GMOs), which may have unknown health effects.

To ensure you’re getting the healthiest and most sustainable fish, look for wild-caught options that are low in mercury and come from responsibly managed fisheries.

Is canned fish safe to eat while pregnant?

Canned fish is a convenient and affordable option for pregnant women to obtain the nutritional benefits of fish without the risk of high mercury exposure.

However, it is important to choose the right type of canned fish. Pregnant women should avoid canned fish that are high in mercury, such as tuna, and instead opt for canned fish that are low in mercury, such as salmon, sardines, and anchovies.

Canned fish should be stored and prepared properly to reduce the risk of food poisoning. Pregnant women should ensure that the canned fish is properly cooked or heated before consumption and should avoid eating canned fish that are past their expiration date.

It is recommended that pregnant women consume no more than two to three servings of canned fish per week to minimize the risk of mercury exposure.

Overall, canned fish can be a safe and healthy addition to a pregnant woman’s diet, as long as the proper precautions are taken. Consult with a healthcare provider before making any significant dietary changes during pregnancy.

Many pregnant women wonder if it is safe to eat canned fish, and the answer is yes, as long as the can is undamaged and the fish is cooked properly.

Canned fish is a convenient and affordable way to add more protein and omega-3 fatty acids to your diet during pregnancy. Look for cans that are not swollen, dented, or damaged in any way, as these can be signs of bacterial growth or contamination.

Make sure to also check the label for any added ingredients or preservatives that may not be safe for pregnant women, such as high levels of sodium or artificial colors and flavors.

It’s also important to cook canned fish thoroughly to kill any bacteria that may be present. This can be done by heating the fish in a pan, oven, or microwave until it is steaming hot.

Overall, canned fish can be a safe and healthy addition to your pregnancy diet, but be sure to choose cans that are undamaged and cook the fish properly to reduce the risk of contamination.

What are the risks of eating canned fish during pregnancy?

While canned fish can be a healthy and convenient choice for pregnant women, there are some risks to be aware of. One risk is the potential presence of mercury in certain types of fish. Pregnant women should avoid high-mercury fish such as shark, swordfish, king mackerel, and tilefish.

Another risk is the sodium content in canned fish. Many canned fish products contain added salt, which can contribute to high blood pressure and other health issues if consumed in excess. Pregnant women should choose low-sodium options when possible.

BPA Exposure

Bisphenol A (BPA) is a chemical that is commonly used in the production of some types of plastic containers, including those used for canned food. BPA can mimic the hormone estrogen in the body and has been linked to a range of health concerns, including reproductive problems, developmental issues, and cancer. Pregnant women may be particularly vulnerable to the effects of BPA, as exposure during pregnancy has been associated with adverse outcomes, including low birth weight and behavioral problems in children.

Although the amount of BPA found in canned fish is generally low and considered safe by regulatory agencies, some experts recommend that pregnant women limit their consumption of canned foods and choose fresh or frozen seafood instead. Additionally, some companies have started using BPA-free can linings, so pregnant women may want to look for canned fish that is labeled as BPA-free.

To further reduce exposure to BPA, pregnant women should avoid microwaving food in plastic containers, as heat can cause BPA to leach into food. Instead, use glass or ceramic containers to heat food in the microwave. Additionally, try to avoid drinking from plastic water bottles or using plastic containers to store food, as these can also contain BPA.

How much canned fish can you eat while pregnant?

Follow the recommended guidelines: The American Pregnancy Association recommends that pregnant women consume no more than 12 ounces of canned fish per week, and no more than 6 ounces of canned albacore (white) tuna per week.

Consider the type of fish: Some types of canned fish have higher levels of mercury than others. Choose lower-mercury options such as salmon, sardines, and shrimp.

Monitor your overall mercury intake: Be aware of other sources of mercury in your diet, such as certain types of seafood, and limit your consumption accordingly.
