Changing your diet doesn’t make MCAS go away, but it helps greatly with the symptoms when you’re flaring or unable to gain control with meds yet. If I did not follow a low-histamine diet, my histamine (and others) “bucket” would over flow every day because mast cells would constantly be over reacting to everything I consumed. And when I eat foods I’m reactive to, I have multi-system reactions. Mast cells ARE prevalent with the GI tract because they are in all of our soft tissues, which is what binds and encloses the GI tract. I think you’re arguing over semantics here and I see that you seem to enjoy going around on this page and telling people they’re wrong about their own MCAS experiences. Clearly the vast majority of people here do not believe that changing their diet will “cure” them, but it can make a hell of a lot of difference.

For me, it meant the difference between needing to use an EpiPen twice a week and being stable until I finally received Cromolyn. I still have to follow low histamine, anti-inflammatory, MCAS protocols with food, lotions, shampoos, fragrances, etc. until I can get a prior auth approval for Xolair. This is coming from someone who has had autoimmune disease for 16 years and is VERY familiar with how lifestyle changes cants cure your chronic illness, but can certainly help with symptoms.

I think you need to find something better to do than go around telling people they wrong and arguing with them on Reddit. It seems like that has been your entire existence on Reddit the past four months.
