I don't have a bread machine but it sure looks like the bread I remember from BC. This is on my "to do" list.

I think seafood in general will be high in iodine.

This recipe was created by a scientist and posted years ago. I will admit I haven't made it, but it's also supposed to be quite good:  

That sounds like really encouraging progress, and it is great that you are narrowing things down so carefully. It can be surprising how something like added iodine in a milk alternative might make a difference for some people with dermatitis herpetiformis-type symptoms, so your note may definitely help someone else who is still dealing with that last bit of itching. It also sounds like you are finding a more comfortable routine with almond and soy milk, simple safe meals, and watching individual triggers like tuna without feeling completely restricted. This really is a learning curve, and keeping track of what improves or worsens symptoms is often the only way to spot patterns. I hope the dermatology appointment goes well...let us know.

Thank you I will have a look
