Tomatoes are considered a nightshade vegetable. Look it up. All nightshades are inflammatory. Nightshade foods contain solanine, a chemical which some people believe may aggravate arthritis pain or inflammation.

I've become almost allergic to tomato over the past few years and I love them. Whether cooked or not, they immediately give me mouth sores and stomach pain so no more tomatoes. Now I have olive oil and garlic instead of sauce.

Right on the nightshade … eggplant is also not good .

thanks Liz6 for answer my consultant said he never heard of anyone havind flair up from eating tomato s
