Sardines/shrimp/crawfish : Are They Really Ever Gluten Free?


Woolygimp

Recommended Posts

Woolygimp Contributor

If I'm not mistaken most fish farms use fish feed with a mix that can contain wheat derivatives, the problem is that when you eat a simple seafood you're often eating the digestive track of that organism.

Unlike eating a fillet of fish, when you consume a whole sardine, shrimp, or crawfish you're eating more than just it's meat whether you intend to or not.

Technically, isn't it a possibility for some non-digested gluten to remain in the digestive organs of these foods? Say the stomach of a sardine, or for those of you who are familiar with crawfish/shrimp: the black sand vein which AFAIK is their intestines. I'm absolutely certain crawfish farms down here use wheat to feed the crawfish, and my family is in the crawfish boiling business. I LOVE seafood but I'm not sure what to think at this point, can anyone who routinely eats this stuff share whether or not they think these foods are safe to eat?

When does gluten stop being gluten after something else ingests it?

Just to point out, this has absolutely nothing to do with fish in general as I'm sure fish meat in itself is all safe to eat. I'm more or less talking about things like sardines, in which you eat the entire fish (minus the head).

Interesting question - I have never thought of this. I love sardines, and eat them occasionally, and they do not make me sick - I am very sensitive to gluten, and usually have some kind of reaction just minutes after eating something with gluten in it.

It will be interesting to see what others on here will answer...

Make sure you buy "wild caught". Farm raised fish are not very healthy anyway.

wg,

That's a pretty good question. Since you're the one that thought of it, why don't you eat some and let us know what happens?

I always de-vein my shrimp. Also, I've long thought that the farm raised shrimp are basically tasteless compared to "real" shrimp.

Hmmm

Last week I got glutened for the first time in a while. I never eat out and was eating the same old fruits/vegs/honey/chicken/eggs/nuts EXCEPT for a tin of herring that the company called gluten-free. I have never eaten this brand of fish before and cannot imagine where else the gluten could have come from. I wrote to the company (which can remain nameless for now) and received what I perceived as a very insulting reply stating that even a 7 year old could understand their labels.

So, thank you Wooly, for perhaps pointing me in the right direction here.

In the meantime. I have had zero problems with Chicken of the Sea smoked sardines, so I'll stick with them.

I eat shrimp from my local publix supermarket on a bimonthly basis, and have never been sick from them. I am really really super sensitive to gluten, I actually get sick within a few minutes of eating the stuff. I do devein my shrimp... I also eat tilapia, shark, halibut and haddock on a regular basis and none have made me sick. I do eat canned tuna but no other canned fish. I hope this helps you out!

Shrimp is always going to be gluten free because they are almost never farm raised.

I'm really curious about crawfish, because they are exclusively farm-raised and they ARE fed wheat.

I avoid farm-raised shrimp for this reason. But sardines are NEVER farm-raised, as far as I know, they are always wild-caught. So they should be definitely be safe, assuming there is no cross-contamination after they have been caught. They are actually the primary animal protein in my diet, and I am super-sensitive. They're also extremely nutritious, sustainable, and low in mercury.

I found this thread because i googled "canned fish super sensitive celiacs", in an attempt to find information on particularly reliable/safe brands. I just wanted to post my opinion on here in case anyone else came across it in the same way, so that they would not be discouraged from eating sardines. 

Maybe i should post in another thread or start a new one about this, but the reason I'm looking for safe brands of canned fish is because the brand I used to use and consider quite safe, crown prince, turns out to be unacceptable by my standards. It took many, many emails to them to finally get a clear answer to what i was asking, and i was actually treated quite rudely in the process. It turns out that they process/package their products in facilities where there are "co-packers" who may or may not be processing gluten products. I replaced their products in my diet with a certified gluten-free brand which i actually find inferior otherwise in quality, season, and i've had a perceived improvement in my lingering GI symptoms. 

Do you know of any canned seafood brands that use a dedicated facility, kareng? (I'll make a separate post for this if that's what you'd recommend)

Kay even wild caught are eating human provided food: the bait in the traps. I was just out pulling prawn traps with my folks and I almost panicked seeing what the bait looks like. Looks like dog food. Still waiting to hear back from my folks what the ingredients are-they think it's just fish and oils. But the bait was all in their stomachs. Will report, but I'm sure not all bait is created equally. Anyone know the prevalence of prawn/crab/shrimp bait containing gluten filler? I got really sick last night after eating their prawns, but it mighta been the dairy I had that bothered me.

Yeah heard about this years ago, people were talking about the meal they feed farm crawfish containing wheat and the way their digestive tracts worked would leave gluten in their gut...that black line running down the backside your eat. and sucking on them etc. Heard farm shrimp where less likely but equally as bad. I honestly do not know, and I think it was a scare tactic. I would love to take some of the meat straight out of boiled ones fresh and see a study of them being gluten tested. Perhaps testing the water of fresh boiled ones to see if it releases gluten  from their insides when cooking if they consumed it as diet.  I do not think anyone has ever done this kind of study. I honestly have not had any in years. I stick to wild caught lump crab maybe once every other month and some wild caught salmon, I do sometimes have swai once every few months. I do not digest meats that well and only eat them in moderation....I have not had a red meat and swallowed in at least 6 months (chef I cook it, set some aside try it and spit to make sure it is right).  Tempted

      Under the circumstances, your decision to have the testing done on day 14 sounds very reasonable. But I think by now you know for certain that you either have celiac disease or NCGS and either way you absolutely need to eliminate gluten from your diet. I don't think you have to have an official diagnosis of celiac disease to leverage gluten free service in hospitals or institutional care and I'm guessing your physician would be willing to grant you a diagnosis of gluten sensitivity (NCGS) even if your celiac testing comes up negative. Also, you need to be aware that oats (even gluten free oats) is a common cross reactor in the celiac community. Oat protein (avenin) is similar to gluten. You might want to look at some other gluten free hot  breakfast cereal alternatives.

      After the birth of my daughter nearly 6 years ago, my stools changed. They became thin if they happened to be solid (which was rare) but most of the time it was Bristol #6 (very loose and 6-8x a day). I was on various medications and put it down to that. A few years later I went on this strict "fruit and meat" diet where I just ate meat, fruit, and squash vegetables. I noticed my stools were suddenly formed, if a bit narrow. I knew then that the diarrhea was probably food related not medication related. I tried following the fodmap diet but honestly it was just too complicated, I just lived with pooping 8x a day and wondering how I'd ever get and keep a job once my children were in school.  This past December I got my yearly bloodwork and my triglycerides were high. I looked into Dr. William Davis (wheat belly author) and he recommended going off wheat and other grains. This is the first time in my life I was reading labels to make sure there was no wheat. Within 2 weeks, not only were my stools formed and firm but I was only pooping twice a day, beautiful formed Bristol #4.  Dr. Davis allows some legumes, so I went ahead and added red lentils and beans. Nervous that the diarrhea would come back if I had IBS-D. Not only did it not come back, it just made my stools even bigger and beautiful. Still formed just with a lot more width and bulk. I've also been eating a lot of plant food like tofu, mushrooms, bell peppers, hummus etc which I thought was the cause of my diarrhea before and still, my stools are formed. In January I ran a genetics test because I knew you had to have the genes for celiac. The report came back with  DQ 2.2 plus other markers that I guess are necessary in order for it to be possible to have celiac. Apparently DQ 2.2 is the "rarer" kind but based on my report it's genetically possible for me to have celiac.  I know the next step is to bring gluten back so I can get testing but I am just not wanting to do that. After suffering with diarrhea for years I can't bring myself to do it right now. So that is where I am!

      I am on day 13 of eating gluten  and have decided to have the celiac panel done tomorrow instead of Wed. (and instead of extending it a few more weeks) because I am SO incredibly sick. I have almost no appetite and am not able to consume the required daily intake of calcium to try to keep up with the loss of calcium from the high parathyroid hormone and/or the renal calcium leak.    I have spent the past 15 years working hard to improve my health. I lost 50lbs, got off handfuls of medications, lowered my cholesterol to enviable levels, and in spite of having end stage osteoarthritis in both knees, with a good diet and keeping active I have NO pain in those joints- til now.  Almost all of my joints hurt now I feel like someone has repeatedly punched me all over my torso- even my ribs hurt- I have nausea, gas, bloating, headache, mood swings, irritability, horrid flatulence (afraid to leave the house or be in any enclosed spaces with other people- the smell would knock them off their feet) I was so sure that I wanted a firm diagnosis but now- I'm asking myself is THIS worth it? esp over the past 2 yrs I have been feeling better and better the more I adjusted my diet to exclude highly refined grains and processed foods. I didn't purposely avoid gluten, but it just happened that not eating gluten has made me feel better.   I don't know what I would have to gain by getting a definitive diagnosis. I think possibly the only advantage to a DX would be that I could insist on gluten-free foods in settings where I am unable to have access to foods of my choice (hospital, rehab, nursing home)  and maybe having a medical reason to see a dietician?   please let me know if it's reasonable to just go back to the way I was eating.  Actually I do plan to buy certified gluten-free oats as that is the only grain I consume (and really like) so there will be some minor tweaks I hope and pray that I heal quickly from any possible damage that may have been done from 13 days of eating gluten.

      So I've been dealing with chasing the name celiac because of my body actively dealing with health issues related to celiac though not eating. Diagnosed in 1994 before foods eliminated from diet. After 25 years with former pcp I googled celiac specialist and she wasn't because of what ive been through. I wanted my results to be sent to my pcp but nothing was sent.I have email copies.I did one zoom call with np with team member from celiac specialist in Nov 2025 and she asked me why I wanted to know why I wanted the celiac diagnosis so bad, I sad I don't, its my life and I need revalidaion because its affecting me.KB stated well it shows you are.I asked then why am I going through all this.I was labeled unruly. Its been a celiac circus and medical has caused anxiety and depression no fault to my own other than being born with bad genetics. How is it legal for medical professionals to gaslight patients that are with an ailment coming for help to be downplayed? KB put in my records that she personally spent 120min with me and I think the zoom call was discussing celiac 80 min ONE ZOOM call.SHE is responsible for not explaining to my pcp about celiac disease am I right?
