You’re correct, and things like celery powder do contain nitrites. These workarounds have never caused me any problems, but I’m sure people vary. I can eat regular bacon every once in a while and be fine, it’s only after a few days buildup that I start the Big Itch (followed by the big hives.) Everyone has to work out their own tolerances.
Oh, that’s very interesting. I never knew what the mechanism was. I never really learned if it had a specific name. It was just something I finally figured out for myself after a lot of grief with no answers from the doctors.
