Probiotic Yoghurt is fine.. but I used to have trouble with the inulin powder that they add to "prebiotic" yoghurts. Just something to watch for.

Yeh that is a nuisance. I was always, until recently, highly reactive to starch. That made it much easier to work out what I reacted to, which is good in as far as I can work things out more easily. Bad though since obviously I had to be more careful than you.
Perhaps you should be looking at more of a low starch diet, and avoiding the very worst offenders, eg. highly refined starch, and deep fried starches. The latter, deep fried starch, is by far the worst of all in my experience. Even though I can now eat starch and bread again, I cannot however tolerated deep fried starches (although french fries seem ok thus far which is kinda weird?!?)
