I'm trying to get an understanding about the link between food intolerances & ibs. How long do people give up foods for before deciding they aren't the culprit & go back to eating them? I've read posts in the past were someone has said they needed to stay off gluten/wheat for 6 months before they were cured/in remission, another said 2 months off dairy healed their ibs. Do most people genuinely leave out suspect foods that long before making the assumption that it isn't the cause or do they only give it a matter of weeks, say 2-4 weeks & then go back to eating that food. I know that if you research most elimination diets they say you should be able to tell of a food is causing a reaction after 21 days but if the gut is damaged enough I imagine you wouldn't be healed properly after that short amount of time. Going by many posts I've read on various ibs sites/forums etc it seems that a lot of people will eliminate say gluten for example for 2 months max & then decide that it isn't that. Maybe the gut just needed more time to heal?
