Every time i eat tomatoes i get diarrhea, it is so abundant food item that i cant avoid it . how can i increase my tolerance to tomatoes ?

Cannot increase it.: you are sensitive to tomatoes and i dont think there is anything you can do to increase tolerance.all you can do is try to minimise your intake of tomatoes.

Tomato: Try various preparations - cooking vs raw; Withdraw for 10 days, then introduce very small amounts and stay with small amount for 5 days, then increase slightly for 5 days, then increase slightly again for 5 days - etc -to see how this might help
