Which tests did you have done? That was one of the things that surprised me when I had the Biomeridian food allergy test done, citrus showed high for me. Olive oil wasn't on the list that was tested, so I don't know how I would have tested for it, that one I was going by the foods high in phenolics.
I'm sure not going to tell anyone to not flush, or stop eating fruits and vegetables. It's just something I was surprised to find out about, yet more common than people would ever realize. For sure it's something I will be aware of now...and I'll probably be able to tell you more about in a few months.
