I had never heard of such a thing so it got my curiosity going. For some reason the phosphate additive stuck with me so I went offsite to peruse different things and here is what I found, verbatim: Phosphate salts can irritate the digestive tract and cause stomach upset, diarrhea, constipation, and other problems. I sincerely hope this helps. I was guessing when I thought that possibly the mercury from the fish doesn't mix well with the added phosphate, but came up empty handed on that. Hope this helps and happy tummy days.

I have experienced the same (mysterious) heartburn symptoms when consuming albacore tuna packed in water (specifically Chicken of the Sea) for the last few months. I typically mix with Best Foods mayo and a little sweet pickle relish. I just want to emphasize that this is not minor irritation and haven't noticed with (any) other foods other than pepperoni-type foods which I no longer consume. No help but at least you aren't alone!

Im commenting because I ate tuna fish today and now I have bad heartburn. I googled it looking for answers, cause I'm on a diet and tuna is on the list but now I have to rethink it,, because I have GERD and that's part of why I'm eating right and dieting

I was searching for tuna/heartburn and found your posting. Like you, my partner and I love tuna! However, it gives both of us severe heartburn if we do not take an anti acid. We also only buy white albacore in water and have the same reaction from all brands we have tried. Hence, only eat it on occasion and only at lunch with a Pepcid first. I also know this didn’t help, but to let you know there are far more then just you with this inconvenience.

Tuna is high in omega 3 which is a fatty acid. So since you have heartburn and or Gerd.adding fat or acid is a horrible thing to do I have Gerd also and it upsets me when I eat tuna or any kind of Omega Rich fatty acid fish. it also happens when I eat avocados sometimes.hope this helps
