Yes, pregnant women can eat tuna, but there are a few things to keep in mind. It’s important to choose the right type of tuna and limit how much you eat to avoid too much mercury. Stick with light tuna, and try to keep your intake to around two servings a week to stay on the safe side.
Introduction:
Pregnancy can bring about a lot of questions, especially when it comes to food. One common question many expectant mothers have is whether tuna is safe to eat. It’s a convenient and nutritious option, but with the warnings about mercury in fish, you might be wondering: Can pregnant women eat tuna safely?
If you’ve been craving that tuna sandwich or sushi, here’s a breakdown of what you need to know before taking a bite. We'll guide you through the dos and don’ts, so you can enjoy your tuna without worrying about the risks.

Why Mercury Matters During Pregnancy
Mercury is a natural element that can be found in water and soil. The problem with mercury is that fish can absorb it from their environment. Larger fish, like tuna, tend to accumulate more mercury. During pregnancy, high mercury levels are a concern because they can affect your baby’s developing brain and nervous system.
But don’t worry, not all tuna is equally risky. Some varieties have more mercury than others, and that’s what we’ll explore next.
Which Tuna Is Safe to Eat?
Tuna comes in two main types: light tuna and albacore tuna. The type you choose matters when it comes to mercury levels.
Albacore Tuna: This type of tuna tends to have higher mercury levels. If you enjoy albacore tuna, it’s best to limit it to one can (6 ounces) per week. That’s the safe upper limit during pregnancy, according to health guidelines.
Light Tuna: This variety is made from smaller species of tuna, like skipjack, and has lower mercury levels. It’s much safer to eat more frequently, and you can safely consume up to 12 ounces (two servings) of light tuna each week.
So, if you’re planning to enjoy tuna while pregnant, light tuna is the best option for you. It’s the safer choice, and you can include it in your diet without worrying about mercury as long as you stick to the recommended servings.
What About Sushi?
If you’re a sushi lover, you may be wondering if you can still indulge in tuna rolls. The answer is: not raw tuna. Pregnant women are advised to avoid raw fish, including raw tuna, due to the risk of harmful bacteria and parasites. These can be especially dangerous during pregnancy.
Instead of raw tuna, consider cooked tuna sushi rolls. You can also make your own tuna rolls at home using cooked tuna to ensure it’s safe. There are plenty of ways to enjoy the taste without compromising your health.
Tuna’s Health Benefits for Pregnancy
Even though there’s concern about mercury, tuna is still a great source of important nutrients during pregnancy. It’s packed with omega-3 fatty acids, which are essential for your baby’s brain development. Omega-3s also promote your overall health, supporting heart health and reducing inflammation.
So, while it’s important to be mindful of how much you eat, tuna can still be a beneficial addition to your pregnancy diet. Just make sure to follow the guidelines for portion control, and you’ll be fine.
How Much Tuna Can You Safely Eat During Pregnancy?
The key to enjoying tuna safely during pregnancy is moderation.
For albacore tuna: Stick to no more than 6 ounces (one can) per week.
For light tuna: You can have up to 12 ounces (two servings) per week.
This allows you to enjoy the nutritional benefits of tuna while minimizing the risk of mercury exposure. If you have any doubts or concerns, don’t hesitate to ask your doctor or nutritionist for advice.
What Happens if You Eat Too Much Tuna?
Eating tuna in moderation is important, but what if you accidentally eat too much? While one or two instances are unlikely to harm you, consistently exceeding the recommended amounts could expose you to harmful mercury levels. This can impact your baby’s development, particularly in areas like brain function and motor skills.
If you’ve eaten more tuna than recommended, it’s a good idea to monitor your diet moving forward. If you experience any unusual symptoms, like numbness or tingling, or if you’re concerned about your mercury intake, contact your healthcare provider for advice.
Other Safe Fish Options During Pregnancy
Tuna is just one of many fish you can enjoy during pregnancy. Other options that are low in mercury and high in nutrients include:
Salmon: Rich in omega-3s and vitamin D, salmon is a great choice for expectant mothers.
Sardines: Small and low in mercury, sardines are packed with omega-3s and calcium.
Trout: Another excellent option that’s low in mercury and rich in omega-3s.
These fish are healthy alternatives that you can safely include in your diet during pregnancy.
What to Do If You Accidentally Eat Too Much Tuna
If you’ve eaten more tuna than you should, try not to stress. It’s usually okay if it happens once in a while. Just be mindful going forward and limit your tuna intake. If you’re ever worried or feeling off, it’s always a good idea to talk to your doctor for reassurance.
