I don't know them before


Goodness of tomatoes are well known. I knew that tomatoes are not good for kidney patients on low potassium diet. Also people with stones are asked to avoid or have it seedless. I was not aware of the side effects that can be caused by tomatoes. How many can one have in a day?? Should one avoid tomatoes if suffering from these conditions or eating tomatoes can cause them?? Please clarify
