Seafood is a great source of many nutrients like omega-3 fatty acids and protein. It is also low in fat. Add to this that it is high in zinc and calcium and it sounds like a perfect food for pregnancy.

The problem with many fish and seafood items are the mercury levels found in these fish. The methyl mercury accumulates in fish with long life spans, hence the specific warnings about certain fish. There is also a danger with PCBs (polychlorinated biphenyls). This was once used in electrical equipment but is now banned. However, it can still be found in many lakes and streams, there fresh caught fish not a part of a commercial production is more at risk.

While fish and seafood can be great sources of nutrients, there are also certain recommendations that pregnant and nursing women should follow:

  • Do not eat shark, swordfish, king mackerel or tilefish as these contain the highest levels of the methyl mercury.
  • Do not eat fish caught by family or friends, stick to commercial fish.
  • Limit fish intake to about 12 ounces of cooked fish per week. (A typical serving is 3-6 ounces.)
  • Avoid raw fish or undercooked fish.
  • Your fish should be kept frozen or refrigerated until you are ready to use it.
Shellfish, canned fish and smaller ocean fish are safe for the pregnant and lactating women. However, the FDA still recommends limiting the amount of fish per week. The Environmental Protection Agency (EPA), also recommends checking for local warnings. When you're dining out or eating fish away from home, be sure to ask where the fish came from. Giving up Sushi is also important because of the raw fish content. And, as always, use proper hygiene when cooking and always make sure your food is well cooked before eating it.
