Fish as Part of a Healthy Diet

Eating fish every week is a healthful goal for the entire household, especially for moms and developing children. The 2015-2020 Dietary Guidelines for Americans recommend that pregnant or nursing women consume 8-12 ounces of seafood per week. Seafood is low in fat, high in protein, and contains essential nutrients like vitamin D, iodine, and omega-3 fatty acids. Omega 3s provide heart-protective effects and may improve learning ability in children. (1,2)

Fish Safety for Babies

However, certain fish may contain high levels of heavy metals and contaminants like mercury, dioxin, and PCBs.

(4) But, the benefits to your baby of you including fish outweigh the risk. Consuming fish during pregnancy is linked to higher IQ. Protect your unborn child from by managing what type and the quantity of fish you consume.

Check with Your Local Health Department for Safe Fish Recommendations

While your family fishing enthusiast may reel in a prizeworthy-sized catch straight from the water, avoid game fish if you are pregnant or nursing. Unless verified by the local health department, it’s considered risky. Certain fish may be contaminated by chemicals, bacteria, or viruses, which can put a pregnant woman or young child at risk of illness. If you are curious about local fish safety, it’s best to check for fish advisories issued by federal, state, tribal, or territorial agencies before consumption. (7) 

You can search here for fish advisories by state.

If You Don’t Eat Seafood

We get it – seafood isn’t for everyone. But, being fish-free doesn’t mean that you have to miss out on the benefits of omega-3s. There are ways to boost alternative, non-aquatic foods to get them into your diet:

  • Fish-oil supplements (speak to your healthcare provider to help you find the best supplement that will meet your specific needs)
  • Walnuts, hemp seeds, chia seeds, flaxseeds, sesame seeds
  • Canola, sunflower, soybean and flaxseed oils in moderation

Cod liver oil is best avoided because of concerns over the possible toxic effects of vitamin A during pregnancy. Meet with a dietitian to recommend a supplement that will best meet your specific needs. 

Also, check out this article for the amount of omega-3’s supplements recommended during pregnancy. For information about the risks of mercury in seafood, call the U. S. Food and Drug Administration Center for Food Safety and Applied Nutrition Food Information Line toll-free: 1 (888) SAFEFOOD. For more information, you can also visit the FDA’s Food Safety Website.
