I have a hunch that some of them I’ll be able to reintroduce. I think the major culprit was gluten, which I’ve since found out is genetic. Having eaten it most of my life probably created enough immune system upset that I’ve reacted to the other things. At some point I’m going to try reintroducing them one at a time.
Easiest thing to do is peal them.
Your T-cells should eventually calm down but "dough conditioner" can irritate them just like you'd been hit with gluten.
I either have my tongue, lips, throat swell or, in the case of corn syrup solids, I have asthma attacks and end up with pneumonia.
