Food intolerances & sensitivities

I seem to suffer from a lot of these, do you? Is this common in ASC?

I can't eat gluten, dairy, eggs, onions, anything spicey, mustard, and nuts & other fibre scratch my insides so it flares up inflammation in my intestine (IBD).

I was only diagnosed with ASC this year, but was curious if these issues with digestion I've had since 2012 were common for those on the spectrum?
