Olive oil is a big subject evidently-bigger than I thought. I ask people at the beginning of treatment to go on NOT extra virgin olive oil, as the pureness of the olive oil is too much for a bladder that is so intensely irritated. I have heard over time that some oils are adulterated with soy, and, this IS a concern, as virgin or non-virgin-soy is a BIG pain causer.

One of my patients just sent me the following links on the subject. If you have any input, please share so that people can be certain they are consuming the proper non-virgin (list #1-3) extra virgin (3nd #3 on)

Here is a link to the two studies where the olive oil was tested. Both by university of California. The first one tested more brands.
