CRP is c reactive protein, a marker for inflammation. I take pro biotics too, I think they really help. And I try to eat a bit of sauerkraut, trying to heal the system. My fasting number was down and now it's a bit higher, though my afternoon numbers are getting much better. Walking really helps. How do you tell if you are sensitive. My doctor did some tests, and I was sensitive to all the things I eat all the time: almonds, chicken, eggs, dairy, so with celiac what's left?! I eat bacon, avocado, coconut, grass fed beef. Do not understand how it can be eggs, so cruel,but since I've cut back I notice more reaction, wasn't sure it wasn't the carrageenan in the cream, but have mostly switched to goat cheese...don't understand "sensitivity", just know my system is sensitive. And I guess my tummy too.
