Tuna While Breastfeeding? It's Better to Avoid It Now!
Tuna is considered a protein-rich all-rounder and quickly finds its way onto bread, pizza, or in salads. However, if you are breastfeeding, it's worth taking a closer look: This popular seafood can be contaminated with mercury, which can also affect your baby. What this entails and which types of fish are better suited, you can read here.
Tuna While Breastfeeding? It's Better to Avoid It Now!
Whether on pizza, in salads, or as a steak: Tuna is delicious and generally healthy, as it contains important fatty acids and high-quality protein. However, during breastfeeding, you should better avoid tuna. Why this is the case and what alternatives exist, you will find out here.
Why is Tuna Particularly Contaminated?
All oceans are contaminated with mercury and other heavy metals. This problem is not new and has intensified over the years. Plankton absorbs mercury, small fish eat the plankton, larger fish eat the small fish, and thus more mercury accumulates in the animals at each step of the food chain. Tuna, being one of the largest predatory fish, live the longest, eat the most over the years, and therefore store a particularly high amount of heavy metals in their bodies. This accumulation is called bioaccumulation and is a serious problem, especially in oceans affected by industrial waste and other pollution.
Another aspect is that tuna are often caught in areas heavily impacted by pollution. These fish are not only older but also have more time to accumulate harmful substances in their tissues. Therefore, the risk of consuming high amounts of mercury when eating tuna is particularly significant.
But there are limits for mercury in tuna products. Isn't that enough?
That's correct; for tuna and other long-lived sea fish, there is a maximum limit of 1.0 milligrams of mercury per kilogram of fresh weight across Europe. For fish species that do not have elevated methylmercury levels, the maximum limit is 0.5 milligrams per kilogram. The Federal Institute for Risk Assessment states that if these maximum limits are adhered to, no health risks to the general population are expected. However, pregnant and breastfeeding women are considered a particularly sensitive risk group, which is why it is better to avoid tuna.
The health risks associated with consuming tuna are particularly concerning, as methylmercury can be passed on to the baby through breast milk. This means that even if you only occasionally eat tuna, the pollutants can accumulate in your body and ultimately harm your baby. It is important to be aware of these risks and make responsible choices.
Is there Tuna that is Less Contaminated?
Yes, there are tuna products that are less contaminated. An investigation by Stiftung Warentest has shown that the mercury levels in many canned and frozen tuna steaks are below the EU limit. However, there is a risk that the meat of large, older fish ends up in cans. Therefore, it is difficult to ensure that you get a less contaminated tuna.
Stiftung Warentest has also found that younger fish and smaller tuna species tend to contain less mercury. Some brands also offer special products that come from sustainable fishing and have lower pollutant levels. Nevertheless, the risk remains that when buying tuna, you might encounter a product with high pollutant levels. If you still want to consume tuna, make sure to choose products that come from responsible fishing and ideally consist of younger fish.
Which Other Fish Are Affected?
Other large predatory fish such as sharks, grouper, halibut, and barramundi are also affected. These fish have similar life cycles and also accumulate high amounts of methylmercury over the years. Methylmercury is particularly dangerous as it accumulates in the flesh through the food chain and enters breast milk. It can affect the still-developing brain of the infant and lead to learning difficulties.
The dangers of methylmercury should not be underestimated: Studies show that it can lead to lower IQ, general learning difficulties, impairments in language ability and memory, poor visual perception, and delayed motor development. These risks are particularly relevant for breastfeeding mothers who want to ensure they provide the best possible nutrition for their baby. It is important to be informed about the different fish species and their potential contaminations to make informed decisions.
What Sea Fish Can You Substitute With?
Herring, cod, pollock, plaice, coley, and salmon are good alternatives that are less contaminated yet still provide important nutrients. These fish are not only tasty but also rich in omega-3 fatty acids, which are important for the baby's development. They also contain essential vitamins and minerals that benefit the health of the breastfeeding mother. By switching to these alternatives, you can ensure that you retain the benefits of fish in your diet without the risks of mercury.
Additionally, you can also opt for farmed fish that are raised in controlled environments and often contain fewer pollutants. Make sure to choose fish from sustainable farming to protect the environment while utilizing healthy food sources.
What to Do If You Have Eaten Tuna Frequently While Breastfeeding?
Don't worry! The likelihood is high that you have eaten young, less contaminated fish. A small indulgence of tuna on your pizza or in a sandwich will not harm your baby. The dose makes the poison, and occasional consumption typically will not have immediate negative effects. However, it is best to avoid tuna until the end of your breastfeeding period. If you are unsure, talk to your doctor or a nutritionist to make the best decision for you and your baby.
It is important to maintain a balanced diet and ensure that you receive all necessary nutrients while keeping your baby's health in mind. You can also try to vary your fish consumption by incorporating different types of fish and seafood into your diet that are less contaminated.
Conclusion
Tuna contains valuable omega-3 fatty acids and other nutrients, but the high levels of methylmercury make it a risk during breastfeeding. Breastfeeding women should turn to alternative fish species to protect their baby's health. A balanced diet rich in various types of fish can help you and your baby obtain the necessary nutrients without exposing yourselves to the risks of pollutants. Remember that your baby's health comes first, and choose wisely when it comes to your diet. By making informed decisions, you can ensure that you and your baby enjoy the best possible nutrition.
