I have salicylate intolerance. Luckily, it’s cyclical, and I have periods of greater tolerance. I take ketotifen to help stabilise mast cells, but I’ve learned (from reading and experience) that sugar (to which I’m addicted ) is inflammatory.
At the moment I’m able to eat more veg, so long as it’s peeled and in the low-to mid range of the salicylate list. So I avoid tomatoes, peppers, etc.
I also have a theory that a fatty liver may make it harder to produce enzymes needed to metabolise salicylates. So being slim may possibly help my body to function better.
