Jon,
may I suggest that if the symptoms are like hay fever it could be similar to my intollerance. What I find is that I can eat the trigger foods up to a point then I seem to pass a threshold level and the symptoms start. This makes identification somewhat difficult, but my intollerances are to dairy produce i.e. cream, butter, full fat milk, cheese etc. I also get the same symptoms from chocolate and cigarette smoke. Animal fat products also cause me a problem. Quite a list for you to start with! I had the skin tests, years ago, they proved nothing conclusive. The good news is that having identified the triggers I am generally symptom free and dont get colds or flu (kiss of death I hear you say), I use Beconase (on prescription) sometimes, there are others that work too.
Best of luck tracking it down mate.
