I know potatoes are nightshades and people generally recommend to avoid them if you have an autoimmune condition. I am not officially diagnosed with any autoimmune conditions but I do have rosacea, which might be caused by autoimmunity. I have been eating lots of sweet potatoes to keep my weight up but they seem to completely destroy my colon, and give me terrible gas. Potatoes, however, don't cause this. In the comment sections of one of Paul Jaminet's articles he states that the nightshade toxins are in the potato fruit but not the tuber, and I was wondering if there was any truth to this?
