Thanks very much for your reply. I think I might have to try a rotational diet. Its a bit overwhelming. How long did you have to do the diet for ? how are you now ?
It may seem overwhelming at first, but like all things, once you do it for long enough it becomes second nature. More importantly, if it works, then it is well worth the effort.
I did the rotation diet for a year or so. It took some time for me to get it right, as I still had to identify all the foods I already had problems with, so I could exclude them from the diet. The rotation diet actually helped me identify problematic foods. It seems by not eating the food trigger every day, the symptoms became more acute when I did consume it. Currently, I can eat any of the foods I was previously intolerant to, without experiencing a reaction. It's very possible I could have done the rotation diet for a shorter period of time, with the same results, but there is no way to know.
If are are overwhelmed at the prospect of maintaining such a diet, why not implement it for a few weeks as an experiment, and see it helps prevent developing intolerances to further foods.
