Eating Fish During Pregnancy

Fri Feb 16, 2007 at 03:28:20 PM PDT

I'm about 16 weeks into my 2nd pregnancy, and have been avoiding eating fish because I just don't know what is safe anymore. I think I've had fish twice so far (snuck some sushi in), which has been tough because normally I enjoy it. Now it seems that not eating enough fish during pregnancy can actually be detrimental to your future child. A team of researchers tracked the eating habits of 11,875 pregnant women in Bristol, Britain.

Hibbeln and his colleagues concluded that women who ate more than 340 grams per week of fish or seafood -- the equivalent of two or three servings a week -- had smarter children with better developmental skills. Children whose mothers ate no seafood were 48 percent more likely to have a low verbal IQ score, compared to children whose mothers ate high amounts of seafood.

These results were enough to catch my attention, but now I am even more confused than ever. Which fish are safest? There are so many conflicting studies that my reaction has been to cut fish out of my diet entirely. At this point in my 2nd pregnancy it sounds like I should be adding fish back onto the menu, and I'm even thinking that it doesn't matter a whole lot what kind of fish it is. This study suggests that by limiting fish intake, we're doing the very harm to our children that we are trying to prevent.

Eating even more than three portions of fish or seafood a week could be beneficial, Hibbeln suggests. "Advice that limits seafood consumption might reduce the intake of nutrients necessary for optimum neurological development," he and his colleagues wrote.

I'll do my best to figure out which kinds of fish are safest (I know about Wild Salmon, but it seems unusual to ever see any of the other "safe" fish on a menu in a restaurant). What about the rest of you? Any recommendations? How did you incorporate enough fish into your diet while pregnant? The linked article is fairly brief, so check it out. I'm interested to hear what you think about this topic. In the meantime, it's Fish n' Chips for dinner for me tonight!

  • What's the correlation? (0 / 0)

    There's certainly stuff in fish that's good for developing brains.  But is there a class or culture aspect to the amount of fish in the diet?  (Guess I'll go read and find out.)  I may have eaten no fish, because I live in Arizona, grew up on Massachusetts, and just can't bring myself to eat seafood so far from the sea.  
  • They didn't (0 / 0)

    actually test the kids?  And it was self-reported?  

    Mmmm...fish and chips.

  • Indeed (0 / 0)

    this is yet another study that contradicts another study that contradicts yet another study - all of which are basically based on suspect 'science' - I wonder if Bumblebee or some company funded this!?!? This kind of science and scientific 'reporting' makes me crazy! I had this same rant on a different diary subject just the other day!

    And, many, many super smart kids are born to vegetarian moms, moms who are allergic to fish, moms who don't like fish, and the millions of moms in the past decade or so who gave up fish because of high mercury levels!

    In the words of my almost 5 year old DD, "Whatever!"

    • Not Bumblebee... (0 / 0)

      "The study was primarily funded by Britain's Medical Research Council, the Wellcome Trust, the University of Bristol, and the British government."

      It sounds as if the lack of Omega-13 is what causes the disparity in brain development. I'm not sure what the exact science is, but it was a large enough sample of women to make me take notice. I'd love to be able to say "whatever" but this issue has truly confused me for so long, I just want to make the right choice for my family's health. The mercury contamination is just one facet, because I also want to be conscious of not eating fish that are dwindling in population. Ulitmately if this study spurs wider research that can give a more definitive answer, I'm for that.

        You sound like you're from UK like me?
        Anyway I was always told by my ob/gyn NOT to eat too much fish because of the high mercury content! I undertsand about the omega 13 connection but it's so frustrating about contradictory findings.
        Good luck with your pregnancy.
        We LOVE fish n chips in our house! With baked beans and veg.
  • I'm like you (0 / 0)

    I got so confused I just pretty much cut fish out.  This wasn't so difficult for me since I'm not a vegetarian, but I think it would be hard if you depend on fish for the bulk of your protein.

    Then again, I gave birth at 28 weeks, but he is healthy, so who knows?

  • would fish oil tablets... (0 / 0)

    ...or some other supplement do the trick?
    • Fish oil (0 / 0)

      It can also be contaminated from mercury, so it means we have to read labels. Some brands at Whole Foods and the like specifically mention that the fish were not contaminated.

      Gross side note, has anyone else ever been able to take fish oil tablets? I have reflux problems and whenever I take the tabs I burp up nasty fish oil for hours afterward -- NOT what a pregnant lady needs in the morning!

    • Coromega (0 / 0)

      My son takes Coromega fish oil packets.  They actually disguise the flavor of the oil quite well!  He hasn't reported any fish burps.

  • I was pregnant 11 years ago (0 / 0)

    so everything is different now, but I ate salmon about once a week and occasionally ate other seafood [generally shrimp]. I mainly ate the salmon because I thought it was healthy and really wanted it that often.

    My kids are smart but I don't think it has much to do with the fish. I think it's because DH and I are fairly smart and we have always tried to make life a learning experience for them. But I think it's mostly genetic -- although, somehow DH and I both think they are way smarter than we are!

  • Fish Safety and Sustainability Guides (0 / 0)

    I am pretty careful about buying seafood and use a handy guide from the Montery Bay Aquarium Seafood WATCH program. They have regional guides that address safety and sustainability.
  • Suggestions (0 / 0)

    I would say wild salmon is good. Sushi is right out.

    You can buy frozen wild salmon year round, and also frozen farmed tilapia, and it should be safe mercury-wise and be very healthy. (Trader Joe's has both, yum.) There is also the option of canned salmon, though that doesn't work for me.

    What you're looking for is quality fatty acids, especially Omega-3s. Other sources, besides fish, are flaxseed (grind it and it's great in breads or pancakes), and the fancy omega-3 eggs, which also tend to have DHA. I definitely recommend those if you're pregnant or nursing. They're steep for eggs but eggs are very cheap.

    Avocados are a good source of Omega-6 fatty acids and are very nutritious overall.

    I have taken an omega-3 fish based supplement from Nordic Naturals from time to time. It is expensive but not at all fishy. I believe from the label that it would be mercury free, but if I were pregnant I would probably dig a little deeper to be sure.

    • Thanks for the tips (0 / 0)

      I know, I really crave sushi...my midwife said that it's probably fine if it's from a reputable place. I.e., if I'd never been sick there before it's probably fine. But, I know that it's best not to toy with it. Thanks for the other tips, I will look into those. I do buy the Smart Balance with Omegas spread instead of margarine, and considering one of my major food groups lately has been mac n' cheese, I've used quite a bit of it up.
      • Sushi tip (0 / 0)

        I love sushi too, and what I did when I was pregnant was stick to stuff like California Rolls, Veggie Rolls, etc. I made sure that all of the stuff in it was cooked. I smeared on lots of Wasabi and enjoyed. There was a little piece of me that worried about cross contamination, but like you said, if it is from a reputable place, it should be fine.
  • Mother's IQ (0 / 0)

    If they didn't test the mother's IQ, which they didn't mention, I would ignore this study. And they based the finding of advanced developmental skills on the mother's observations? Isn't that a little problematic?

    And - 48% increased chance of having a low verbal score. What did they consider low? Lower than what?

    The reason I bring up the mother's IQ is because I looked into the connection between breastfeeding and IQ. There was a big splash in the media that kids who were breastfed had a 3 or 5 point increase in IQ compared to not breastfed (a meaningless difference in real life, but that is a whole other problem). A couple of years ago, the American Academy of Pediatrics did a review of the literature, and found that the studies that found a difference did not test the mother's IQ. Two studies did test the mother's IQ, and in those studies, IQ of the kids was correlated to the mother's IQ, not breastfeeding. When the mother's IQ was factored in, the influence of breastfeeding or not disappeared.

    If I were preggers, I would eat fish, if I could find it without mercury (which is without a doubt a negative), if I liked it, and forget the rest.

    • some (0 / 0)

      For some reason, I would think that eating seafood would correlate with higher IQ, or at least higher socioeconomic class, which also correlates with children's IQ.
      • Exactly (0 / 0)

        IQ and verbal scores and such are so associated with socioeconomic issues that I always am a little dubious about these studies that make a big splash in the media.

        It's like you said on an earlier thread, the reporting of research results is often geared toward headlines. Esp if they at all feed into parents fears!

        RachelD

        • IQ (0 / 0)

          I also think that our obsession with IQ scores is over-the-top anyway.

          There are plenty of people with average IQs that are super successful, and plenty of people with very high IQs that aren't.

          Of course, you want to be in the average category, or high average, I'm not underestimating the struggles of those in lower brackets.

          But really, does 5 points here or there make a difference?

           

          • Agree (0 / 0)

            I totally agree ... there's nothing like IQ to get people going. I think it's one of the most abused ideas in education, and hopefully not parenting now.

            Geek info: the standard deviation in IQ is 15. 100 is defined as average. Truly, a five point difference would make no difference in someone's school performance or life success, as you're saying.

            Most of us will never even know our kids' IQ because it has to be done by a trained psychologist, one on one. Beware "IQ" numbers that come from anywhere else!

  • Smart Fish Guide for Moms (0 / 0)

    Institutue for Agriculture and Trade Policy has lots of information about health and trade issues, including a Smart Fish Guide for Moms and a How Much Mercury is in That Calculator. .

    Bonus issues: arsenic in chicken, buying safer plastics, safer produce, and more. (You'll want to hole up on an organic farm if you spend too much time on this site.)

  • Fishy research (0 / 0)

    Did they test the educational attainment or socioeconomic class of the moms -- or did they control for those variables?  I'd be interested to see if more educated women were more or less likely to eat fish.  If they didn't control for that, it could throw off the study.
    • Right (0 / 0)

      Yes, I'm curious about all of the factors in the households. I wonder if the kids were "smarter" because of an overall better diet while the mom was pregnant and during early childhood. Perhaps the mothers' diets were more varied than the no-fish eaters. Maybe they also tended to breastfeed, or lived in an area with lower pollution? There may be an article out there that goes more into detail than this one, I haven't really searched.
  • Expecta (0 / 0)

    I recommend these....they purify algae to get the omegas, which is where fish get them from anyway.

    • Tried this (0 / 0)

      I got a sample of these from my midwife/doc's office, and gave them a try. I'd be willing to take them, I'd just have to deal with the fishy burps...they did give me that reflux. But, if it's in the afternoon or evening it's more tolerable than if I take them in the morning.
      • Did (0 / 0)

        Did they give you burps?

        I've been taking one with dinner and I didn't notice anything different, but I am not preggers  : )

        • Yeah (0 / 0)

          They did. I have a hiatal hernia so constant heartburn even from a glass of water is a problem. When pregnant, I also get terrible reflux. When I was in the 3rd trimester last time I had to sleep sitting up because I'd wake up choking! Basically I have to cut off any food after 6 (though that is tough), and have small meals.
          • gah! (0 / 0)

            that sounds really uncomfortable. I don't normally suffer from heartburn, but boy did I get it from about the seventh month on (I think. Probably a good thing I don't remember precisely...). The things we do for children, eh???
  • there are other ways (0 / 0)

    ...to get what fish has in it.

    omega 3, etc. i am vegetarian and did not eat any fish. it does not appear that my son has any hindered intelligence.

  • I ate sushi (0 / 0)

    Through both pregnancies and both my kids are dumb as bricks.

    HAHAHAHAHA

    That is something you'll never hear anyone say, even  though in my case the first half is very true and the second half has been unproven yet.  ;)

    • ha! (0 / 0)

      I ate Sushi as well, doctor said it was fine in small amounts. I LOOOOOVED Tuna while I was pregnant- I hate mayo so I had never even tried tuna until they started those packets with the seasoning ( the garlic one is soooo good!). Anywho, my doctors were very liberal about everything, and they said the tuna was good brain food as long as I wasn't eating it every day

      I would just call the nurse practitioner or doctor and just see what his or her opinion is. I had friends whose doctors told them to avoid all sorts of things that my doctor never mentioned.

    • Love it! (0 / 0)

      That's hilarious!

      I think a lot of it is just precaution. Like the brie thing -- sure, it's serious if you're the one person who gets sick from it, but I don't know anyone who ever has. I'm not putting on my bread every day, but I've enjoyed a bite here and there at a party. My midwife also said the same thing about eating a turkey sandwich. I'm going to do my best I can with the fish I eat, but I know that it's probably fine if I eat something "wrong" once in a while.  

  • Its tough (0 / 0)

    I'm still nursing and I am careful about the kinds of fish I buy/eat/feed my family. It is scary and confusing, but I love seafood too much to completely cut it out. I ate fish when I was pregnant and tried to stick to the list of safe/safer kinds of fish.
  • Wild salmon (0 / 0)

    A little note about wild salmon -- it need not be expensive. You can get it canned, which is pretty cheap.
    All salmon from Alaska is wild salmon (tooting my own state's horn here) because salmon farms are illegal in Alaska. Beware of anyone who purports to sell "farmed wild salmon," as some New York restaurants and fish-sellers did in the past. Farmed and wild are mutually exclusive.
    It's worth buying Alaska salmon for another reason -- despite our crazy politicians, Alaska, unlike most states, has had very good overall salmon management over the years. Supporting the Alaska salmon industry means supporting an environmentally responsible industry, on the whole.
    Also good are Pacific cod, halibut (under 50 pounds) and, in general, other wild Alaska species of commercially caught seafood.
    • This is what I buy (0 / 0)

      I agree -- I'm a stickler when I buy salmon. It's disgusting that the typical offering at the grocery store is farmed salmon WITH COLOR ADDED! It's right on the label...I don't know how anyone would choose to buy that. The trouble is, my DH really dislikes salmon, so when I look for fish to prepare for dinner (he's fine with fried fish which kind of negates the health benefit IMO), I have a hard time finding the other "good" kinds at the market. I found tilapia at Trader Joe's but that's it.
