Oh the list is very long! But some things are higher than others, and some people may be more sensitive to some things on the list, some to others.
Particularly bad are: alcohol, fermented/pickled stuff, seafood, chocolate, matured cheeses, processed meat, citrus fruit, nuts.
In a way, it would not be bad in terms of a healthy diet - fresh meat, fish, eggs, most veg and most fruit are good.
And I think the fact that I have only had two bouts of major symptoms, 7 years apart, shows that I only have a flare-up when I happen to have been having lots and lots of those foods/drinks. I think I'll try and be quite strict for a while, then cautiously relax it a bit.
