Topic: Irritable Bowel Syndrome (IBS), June 2000
A viewer with IBS was told by her doctor to increase fiber
in her diet and also to cut out caffeine, what is your
opinion on that?
Well, with respect to caffeine there are no
studies that show that caffeine has an effect on irritable bowel, so I
can't really comment there.
As far as fiber
, the studies, as I previously
mentioned, have been contradictory, but there have been some studies that
show that fiber--which fruits and vegetables contain--can improve
irritable bowel syndrome
. But most fruits and vegetables can cause loose
stools especially when eaten raw. This occurs because of the effects of
fiber, which is primarily cellulose in the fruits and vegetables. However,
when eaten in normal quantities it is rare that fruits and vegetables
cause troublesome diarrhea
. If fruits and vegetables do cause diarrhea
then something else should be considered such as fructose
which is a rare problem, but since some fruits are high in fructose it can
be a cause of diarrhea
in those individuals.
