Seafood, IBS And Low FODMAP Diets

Grilled swordfish
Grilled swordfish is a great idea for a low FODMAP dinner.

In early 2000 when I was nearly finished with my undergrad work in Cultural Anthropology, I started having gastrointestinal problems. At first it was chalked up to diverticulitis, but test, after test, after test, nothing was seen. Since several GI specialists could not find the reason for my abdominal pain and changing bathroom habits, my issue was diagnosed as Irritable Bowel Syndrome (IBS). For the next 8 years I saw my earning potential fall off a cliff as I lost 3 jobs in that span because of IBS. It forced to to radically change how I lived my life and what lead me to falling back on my knowledge of local history and my love of writing to attempt to make a living.

What frustrated me is that all the “good” advice I got about trigger foods and lifestyle changes didn’t seem to help. In fact for a large portion of time I had manageable symptoms even though I was just going about my business. However I have noticed that the pendulum is beginning to swing and I have not been feeling so great lately. And without getting into too much of the gory details, lets just say my bathroom habits are changing again. I have been getting increasingly uncomfortable and bloated on top of the usual cramping and bathroom visits.

I have told many of my doctors that I believe my IBS is cyclical: when things are bad, nothing helps, but when things are good, I’m bulletproof. This time around I noticed that my IBS was flaring up at the same time that reflux and my sinuses were causing problems. I had chronic sinusitis which required surgery a few years back, but since that time I have not had a major IBS flare. I found it interesting that both were giving me problems. I decided to look into the connection between IBS, reflux/GERD, and chronic post nasal drip/sinusitis.

Full disclosure: I do NOT buy into alternative therapies and/or homeopathy. I worked in a health-food/alternative medicine store in college so I am well versed in the concepts and tried many of the remedies. Some of that stuff does work, but before I try it I need hard, peer-reviewed science. And so I was surprised when I found several articles online thanks to Google Scholar, that suggested a link between IBS and sinus problems. One approach that seems to help is something called a low FODMAP diet.

FODMAP is an acronym for the short-chain carbohydrates that can cause IBS symptoms:







I started a low FODMAP diet in June for two weeks before our annual St. Peter’s Fiesta. After that short amount of time, I noticed a difference, I also noticed that every time I ate a food high in FODMAPS during the festival, I felt bloated like I used to. I’ve been back on since July 5th and although it can be frustrating, I do like the way I feel so far.

I’m just about to start reintroducing certain foods back in and I’m already seeing patterns. For instance I have a feeling I will be able to tolerate wheat in small amounts, but not products that have added soy. Although not FODMAPS, I’ve learned the hard way that certain gums like guar and xanthan, added to foods, (especially gluten free and lactose-free ice cream) gives me a real hard time.

Seafood as Part of a Low FODMAP Diet

Like nearly all protein, fish and shellfish are low FODMAP, however depending upon how you like your seafood, you will have to change up your recipes. If you’ve read this blog before, you know I love breadcrumbs, either made from local Italian bread or buttery Ritz crackers. Those are out at least until I start the reintroduction phase. Same for onion, garlic and mushrooms. However I’m not really missing them as much as I thought.

Dover Sole
Something as exquisite as Dover Sole Meunière can be modified for a low FODMAP diet, by using plain gluten-free flour or an alternative like corn, rice or buckwheat. Just make sure you can tolerate butter.

When it comes to fish, the low FODMAP diet is perfect for the grill or grill pan. Swordfish, tuna, salmon, barramundi, striped bass, mahi…all of them are great on the grill. Flaky fish, especially if using skinless fillets, can be grilled or baked in a foil pouch along with FODMAP friendly ingredients.

Shellfish lovers can still enjoy oysters, clams, scallops, lobsters and more. However, your steamers and mussels will have to omit any garlic or onion, but a can of beer or glass of wine should still be fine for the steaming liquid. Keeping in mind that alcohol can be a gut irritant. For the fried clam lovers out there, a breading made of corn meal is low FODMAP, but most places use some wheat flour.

If you omit the onion and garlic, and use lactose-free milk or cream, you can even make a chowder. Instead of using oyster crackers, get yourself a artisan loaf of sourdough bread (make sure it’s made with a sourdough starter, no yeast).

Simple preparations of olive oil, lemon, salt and pepper are great on all kinds of fish. Nearly all herbs and spices are OK as well, just make sure you check the ingredients before using spice blends or rubs, they usually have garlic and onion powder in them. Sorry Old Bay fans, but there are all sorts of FODMAP friendly spice blends available, including low FODMAP seafood seasonings.

I recently had a couple of seafood meals that contained potentially high FODMAP ingredients: Baked scallops and fried clams. The breadcrumbs and herbs on the scallops did give me a feeling of bloatedness shortly after eating, but no long term effects. The fried clams even less so, since the breading is lightly seasoned and had a high ratio of corn meal, which is low FODMAP. However it does not take long to get back to the new “normal” so you don’t have to beat yourself up if you’re finding yourself eating things with high FODMAP ingredients…just don’t make it a habit in the initial phase of the diet.

If you are interested in getting started on the low FODMAP diet take a look at the Monash University FODMAP website. They also offer an app to help you sort out what you can eat during the phases of the diet. You should also notify your primary care physician, they may be able to offer insight into how to stay healthy: for some, this diet is not a major change, but for others it is significant. You have to find alternative sources for things like vitamins, calcium and especially dietary fiber.

As I find my way through this new diet, I will make sure to be clear if foods or recipes I try are low FODMAP. If you are an advocate of the low FODMAP diet, and a lover of seafood, please share your experiences in the comments below!



  1. As a fellow IBS suffer I found your post very interesting. I’m with you regarding the cyclical nature of IBS. I’ve learned and continue to learn triggers and avoid them. For me, my best improvement was after retirement and reduction of stress and travel foods. Thanks for the info on the FODMAP, it all makes sense to me.

    • Thanks for visiting Ron. I wish I found out about FODMAPs earlier, something about the concept just “clicked” for me. It’s a tricky diet but even when I make a mistake I still feel I’m headed in the right direction.

  3. This was very interesting and great to read. I have been on a FODMAP diet now for 4 weeks and I feel so much better after not knowing what I was going through for the past 6 months. I was diagnosed with rhinitis 7 years ago so it was interesting to read your paragraph on sinus issues and IBS. I’m not sure if IBS is hereditary as my 3 aunties suffer with IBS and my grandma and great grandma all had stomach issues. This information was very useful to me so thank you

    • Glad to help and I wish you luck. I’m not currently on low FODMAP but I plan on going back soon. It was not a cure-all for my IBS symptoms but I certainly felt much much better and by omitting junk food and beer I even lost weight!


  4. The timing of me finding out about your articles and my daughter having awful tummy troubles couldn’t have been any better! Just ordered the FODMAP book you referred to on another post. It’s encouraging to think my girl may find some relief. If a foodie like you can find some good options this way, then I’m happy to try this for my family 🙂 thanks Justin!

  5. Thanks for your article. I will definitely be trying the low fodmap diet. However every time I eat Salmon I have trouble the next morning Probably due to the fact that it is high in oil. Hopefully this diet helps.
