Are nightshade vegetables bad for arthritis?
AEggplants, capsicums, tomatoes and potatoes belong to the nightshade family and contain alkaloids, such as solanine. While anecdotally some people report increased arthritis pain after eating these vegetables, research has found many of them have anti-inflammatory effects. For this reason, it’s not recommended that you limit your intake of nightshade vegetables, unless you find that they are causing you pain. (See page 54 for more on nightshades.)
