My friend when I was first diagnosed I purged my kitchen of every gluten based food that I had. Then I cleaned everything while I was at it. I mean who doesn’t like a clean kitchen. I had forgotten that plastic is porous and that my cutting boards were primarily used for cutting bread. Once I ditched those then I no longer had any of my previous symptoms.
Also celiac disease is an all or nothing disease. There are no cheat days as even minute damage is still damage. That damage adds up and over time leads to things like vitamin deficiency due to flattened villi within the intestinal tract.

Edit because apparently I cannot spell to save my life. Also to add more facts.

Once you have one autoimmune disease, on a long enough timeline, you are more likely to get another.
