I always understood you should avoid the deadly nightshade family (tomatoes/peppers/aubergine etc) but also heard you should avoid certain grains.
Unfortunately on the web it is all American "specialists" who tell you to watch a video and then I have no doubt will encourage you to spend money on a "wonder drug".
I did manage to get a list of food that was ok and they were umming and ahhing about deadly nightshade foods. One the one hand they were but they contain X which is bad! Also read somewhere that grains, or certain ones are bad but it never clarified which! Doing my head in a bit. Shame that I love tomatoes, peppers and potatoes but if I thought it would help my pain I would give them up!
Anyone?
