You might want to see if you can find the pernicious anemia allergic gastritis diet. It's what I liver with, which makes giving up grains look simple! Part of why so many people of EUROPEAN ANCESTRY have problems is a specific gene error which means we can't handle ANY GRAINS, molds (as in fermented foods, and even some probiotics), salicylates (rife in many plants) and phenols (Ditto! With of note, I live in an area with pinon and juniper trees and when they put out pollen in the spring, I am deathly ill, to the extent I have to leave the area and go south to where they have already finished blooming. That's why I want you to have an intrinsic-factor antibody test because if you have P.A., you need to know it, and no, don't allow your doctor to convince you that your B-12 levels are fine. That's why I went undiagnosed for 31 years. If you don't have P.A., I absolutely know you have SIBO, so GET EDUCATED!
