Hi, @LizAdair. This connection between salads and arthritis seems very unusual. Most people who discuss their ability to tolerate veggies are focused on bowel function and bathroom activity, and that advice isn’t really what you’re asking about. I’d be surprised if it’s really the fiber itself. Jan’s point that vegetables in the nightshade family can be problematic offers a strategy you might try: a vegetable-specific elimination diet. In your case you could test the hypothesis that this is vegetable-specific by adding back one vegetable at a time, and sticking with each long enough to assess your symptoms. Wouldn’t it be great if the problem were (for example) just tomatoes instead of all salads? I hope you can find a healthy diet that’s close to what you’re hoping for - maybe it just needs a few tweaks. Good luck!
