Just thought I'd pass on a link for a useful website. As most of us IBS suffers know, too much insoluble fibre eaten without soluble fibre is an irritant to the gut and bowels. This is a comphensive list of insoluble & soluble fibre content of many foods which you can search through alphabetically. I found a few foods I didn't realise were high in insoluble fibre.
It's an American Prebiotic company but hopefully the list is trustworthy.
