Is It Safe To Eat Sushi When Breastfeeding?

Sushi is safe to eat during lactation and breastfeeding unless it is made from fish that have absorbed potentially high levels of mercury (2). Large fish, such as bigeye and yellowtail tuna, swordfish, tilefish and shark are high in mercury and is dangerous for a developing baby.

Post-birth, a mother’s body provides all the nourishment needed for the baby. While fish is a healthy addition to the maternal diet, sushi made of raw seafood might not be good for the baby if it contains high levels of mercury, which may affect the baby’s health. When having fish or any other seafood, breastfeeding women should make sure that they eat high-quality variety with considerably low levels of mercury.

What Are The Benefits Of Consuming Sushi While Breastfeeding?

Eating sushi while breastfeeding could be quite beneficial because of its nutrient-packed ingredients (3).

  • A standard sushi dish may include rice, nori, fresh fish, and a mix of veggies such as cucumber, avocado, bell peppers, and carrots. This combination may boost lean protein and nutrients essential for a breastfeeding baby.
  • Specialized seaweed, such as nori, used in sushi, is low in calories and rich in minerals, including calcium, magnesium, phosphorus, iron, sodium, and vitamins A, C, and E. Additionally, it may provide the iodine required for proper thyroid functioning. These nutrients are crucial in promoting the healthy growth and development of a nursing infant.

Therefore, consuming properly prepared and thoroughly cooked sushi may positively contribute to the overall health of the breastfeeding woman and her baby.

What Are The Risks Of Eating Sushi When Breastfeeding?

Pregnant women and breastfeeding women should be cautious before having sushi or any other seafood. Most people believe that seafood consumption is potentially a risk for pregnant women and breastfeeding women, as it (1) (4):

  • Contains bacteria: Sushi’s main ingredient is raw fish that may carry bacteria. Bacteria is especially risky for pregnant moms as it can affect the unborn baby. When breastfeeding, a bacterial infection could also hamper the mother’s ability to breastfeed her infant.

  • Increases exposure to mercury: Some fish contain high mercury levels, and intake of such fish can affect a baby’s brain and nervous system.
  • Contains high levels of industrial pollutants: Industrial pollutants containing high levels of germs and bacteria are often dispersed into bodies of water which can in turn contaminate the fish. It is helpful to know where the fish you are eating has been sourced from.

Babies go through phases of rapid development while being breastfed. Therefore, it is better to stay away from food containing mercury when breastfeeding. Not all types of sushi are a risk for breastfeeding women, but you should avoid including sushi constructed from the following fish in your postpartum diet:

  • Ahi (yellowfin tuna)
  • Aji (horse mackerel)
  • Buri (adult yellowtail)
  • Hamachi (young yellowtail)
  • Inada (very young yellowtail)
  • Kanpachi (very young yellowtail)
  • Katsuo (bonito)
  • Kajiki (swordfish)
  • Maguro (bigeye, bluefin or yellowfin tuna)
  • Makjiki (blue marlin)
  • Meji (young bigeye, bluefin* or yellowfin tuna)
  • Saba (mackerel)

  • Toro (bigeye, bluefin or yellowfin tuna)

  • Rice vinegar

  • Nori sheets
  • Carrots

Most cooked fish is safe to consume during pregnancy or while breastfeeding, but it’s important to consider maternal nutrition when making food choices. Fish is a good source of vitamin D and is nutritionally beneficial for the baby too. You may eat between two and six ounces of fish every week assuming they do not contain high levels of mercury. Some acceptable fish choices are:

  • Albacore or yellowfin tuna
  • Catfish
  • Cod
  • Haddock
  • Salmon
  • Sardines
  • Tilapia

Pregnant and breastfeeding women can have two to three servings of various cooked fish to ensure adequate infant nutrition. Omega-3 and omega-6 fatty acids, vitamin D, iron, zinc, iodine, and choline found in fish are important for the mother and the baby. In general, cooked fish is safer than raw fish and breastfeeding mothers should aim to eat well-cooked fish with a low mercury content (6).

Fish such as bigeye tuna and yellowtail are high in mercury and are dangerous for a developing baby. You may prefer higher quality fatty fish as it contains low-level of mercury. Some fish safe for breastfeeding women are:

  • Lake trout
  • Canned tuna

Avoid fish with high amounts of high mercury such as:

  • Swordfish
