Thanks, and I do love apples. Any good literature that you have read on the topic? I'm interested in changing to a more probiotic friendly diet.

There is this study:

Although it is looking into obesity, they did find that apples restored abnormal microbiota.

I suffer from mild IBS myself, and find that eating an apple a day seems to help (although it's impossible to know for sure without doing a double-blind trial on myself).
