This is a question that has come up a LOT on the Facebook SIBO group and I thought I’d give my opinions on the matter having been a vegan and having suffered through SIBO. I was on the spectrum from vegan to pescatarian most of my adult life, I think the last red meat or poultry I ate was at 18 years old until I got SIBO at 53. This was a decision made for religious reasons as well as moral reasons to try and help save the planet and it wasn’t one made lightly. Originally I was hard-core vegan living on rice and soy for the most part then switched to adding dairy and eggs to my diet with some occasional fish. For many years we lived this way, eating fish often when traveling, otherwise maybe a few times a month. Sometime a few years before I got SIBO I started having problems with dairy and went back to being vegan.
