If you google “what can legally be called a sourdough bread”, then I think you might see that this can be a problem.
But anyway, I think we can safely say that sourdough is probably a good way to test whether the issues are really gluten sensitivity, (because it certainly has some), or with other components of wheat.

Also, see https://en.wikipedia.org/wiki/Chorleywood_bread_process. This is surely producing a bread with a rather different chemistry to more traditional processes.
