Canned Tuna
Quick answer
During pregnancy, Canned Tuna comes with a 'caution' verdict. Light canned tuna is generally okay in moderation (2-3 servings/week), but it's wise to limit albacore tuna to just one serving per week due to its higher mercury content. It's all about making informed choices!

What is Canned Tuna?
While a delicious staple, canned tuna requires a little extra thought during pregnancy due to potential mercury levels, especially with certain types.
What is Canned Tuna?
Canned tuna, often affectionately called tuna fish, is a popular and incredibly convenient protein source found in many pantries worldwide. It’s made from various species of tuna, cooked and preserved in oil or water, making it a shelf-stable and versatile ingredient. This pantry hero is beloved for its ease of use, showing up in everything from classic sandwiches and vibrant salads to comforting casseroles and quick pasta dishes.
The two most common types you’ll find on grocery store shelves are "light" canned tuna, which typically comes from smaller skipjack or yellowfin tuna, and "albacore" (also known as "white") tuna. These different types have varying characteristics, including their flavor, texture, and—importantly for our chat today—their mercury content.
Why pregnant women ask about it
It’s totally natural to wonder about canned tuna when you’re expecting! As soon as you see that positive test, a switch often flips, and suddenly you’re scrutinizing every bite and sip. Tuna is such a common part of many diets, and with all the advice out there about seafood and mercury, it’s incredibly smart to ask if your favorite tuna melt or salad is still on the menu. We want to enjoy our comfort foods and maintain a balanced diet, but always with our little one’s well-being front and center.
What research and expert consensus say
When it comes to canned tuna and pregnancy, the main conversation revolves around mercury. All fish contain some level of mercury, a naturally occurring element, but larger, longer-lived fish tend to accumulate more of it in their tissues. For developing babies, high levels of mercury exposure are a concern because it can impact neurological development. This is why experts advise a mindful approach to certain types of fish during pregnancy.
The good news is that not all canned tuna is created equal! "Light" canned tuna, typically made from smaller skipjack or yellowfin tuna, generally has lower mercury levels. This type is often considered okay in moderation for pregnant individuals. On the other hand, albacore (white) tuna comes from larger tuna species and, as a result, tends to have higher mercury content. This is why you’ll often hear recommendations to limit albacore more strictly.
The general guidance from many health organizations suggests that pregnant individuals can enjoy light canned tuna, usually around 2-3 servings (which is about 8-12 ounces total) per week. For albacore tuna, the recommendation is typically to limit it to about one serving (around 4 ounces) per week. It’s all about balancing the wonderful nutritional benefits that fish offers (hello, omega-3s, protein, and vitamin D!) with sensible precautions regarding mercury levels.
Safer alternatives to use instead
If you’re looking for delicious and pregnancy-friendly alternatives to canned tuna, there are plenty of fantastic options that can still provide those important nutrients or satisfy a similar craving! Consider other low-mercury fish like salmon, sardines, or anchovies, which are also packed with those wonderful omega-3 fatty acids. These can be great in salads, pasta, or even on crackers for a quick snack.
For a plant-based twist, mashed chickpeas or white beans can make a surprisingly satisfying "tuna-like" salad, especially when mixed with mayo, celery, and your favorite seasonings. They offer a good source of protein and fiber without any mercury concerns, making them a wonderfully versatile option.

Frequently Asked Questions
Can I eat canned tuna every day during pregnancy?
While light canned tuna is generally okay in moderation, eating it every day might exceed recommended weekly limits for mercury. It’s usually advised to stick to 2-3 servings of light tuna per week, and even less for albacore, to keep mercury intake within sensible limits.
What’s the difference between "light" and "albacore" tuna for pregnant women?
"Light" canned tuna (often skipjack or yellowfin) generally has lower mercury levels, making it a more frequent choice. "Albacore" (white) tuna comes from larger species and has higher mercury, so it’s recommended to limit it to about one serving per week during pregnancy.
Are there any benefits to eating tuna during pregnancy?
Absolutely! Tuna, like other fish, provides important nutrients such as protein, vitamin D, and omega-3 fatty acids, which are beneficial for both mom and baby’s development. The key is choosing the right type and quantity to balance these benefits with mercury considerations.
Should I avoid all fish during pregnancy due to mercury?
Not at all! Many fish are wonderful choices during pregnancy and provide essential nutrients. The advice is to be selective, opting for low-mercury fish like salmon, sardines, and light canned tuna in moderation, while limiting or avoiding high-mercury varieties. Always aim for a balanced and varied diet!
