Is there anything in olive oil besides olives picked from a tree? I have major food allergies . . . I know I get hives from olives out of the can. I've continued to ingest olive oil, but was given cause to question it at a restaurant not long ago. Do you know what olives are related to? Among other things, I'm also allergic to walnuts and pecans, but not almonds and cashews.
The legal definition of Extra virgin olive oil is that it cannot contain anything but olives. No preservatives, no additives, no chemical, heat or other processing is allowed. Seedefinitions
Olives out of the can is an entirely different matter, they must be processed to remove the bitter taste in the watery part of the olive.
Olives are not related to the nuts you mention. See classification for where they fit in on the tree of life.
