Irritable Bowel Syndrome Message Boards | Re: Probably both stress and food

The effects I am talking about have nothing to do with the digestibility of a food. I am talking solely about the effect food can have on the bacteria population in the colon.

If you remove a food from your diet which is acting like a prebiotic (i.e. acting as a food source for colonic bacteria fermentation) then the population of effected bacteria will decrease due to lack of a food supply. This bacteria may be producing gas and other by-products which in turn may effect the motility of the GI tract. If the amount of by-products is reduced due to the decrease in population then the effects will decrease too. When you re-introduce the food you eliminated the population of the particular colonic bacteria that was effected will slowly increase which in turn increases the amount of fermentation by-products produced which in turn will start to effect GI motility again.

It can take several days - even weeks - to notice how a change in diet effects IBS symptoms.
