Although gluten is not naturally found in tuna, sometimes it can be found in canned tuna as an added ingredient. Those who want to avoid consuming gluten as much as possible will definitely need to check the label so they can see for themselves whether or not there is any in there.

By getting your tuna fresh and out of the can, you can avoid consuming any gluten at all. Fresh tuna that is not out of the can also tends to be better and more nutritious for you so that is another benefit to consider when you are trying to figure out which type of this fish to get.
