Irritable Bowel Syndrome Message Boards | Re: Diet and fructose malabsorption

Shawneric,

Interesting post. However, a short note.

Fructose that is in exact balance with glucose is not a problem. For example, white and brown sugar have exactly the same amount of glucose and fructose. It isn't a problem for IBS. The reason as I explained in a previous posting to you, is that when both sugars occur in equal amounts they are absorbed by the body differently that fructose that is not accompanied by an equal amount of glucose. When they occur in equal amounts the fructose is completely absorbed and metabolized in the liver.

Only the excess fructose, i.e. that is the amount of fructose that is above the amount of glucose, is poorly absorbed.

Also, excess fructose need not cause diarrhea although it can in high enough doses. It can also cause cramps, gas and bloating in IBS-D, IBS-C and IBS-A.

For a more detailed technical example read the article linked to in my signature or read this article Malabsorption of Fructose and Other Short-chain Carbohydrates. Both articles explain how fructose is absorbed in the GI tract.
