fructose malabsorption question
      #364879 - 05/24/11 07:57 PM

This chart says to avoid things I thought were safe with FM like orange juice, ginger, stevia? Is this true. I always did have trouble with stevia and didn't know why.

Alisonmary,

I have actually made that chart and have put stevia in the "to avoid" column, because I've interviewed some people with FM and some said stevia was not good for them. There were some people who were surprised about that, so I later wanted to move that in "to try" column, but I cannot access this article right now.

It would be very nice from you, if you can tell something about stevia and do you have FM or any other GI disorder.

If you search in Google for "fructose malabsorption stevia", you can see different experiences with it. I was trying to find "reliable" charts made by known FM researchers, but those charts are either not complete or the authors require some sort of registration or personal contact...

I haven't found any theoretical explanation why would stevia be problematic in FM, but even healthy people may have some food triggers of GI symptoms. Stevia is NOT problematic for everyone with FM, though.

I don't have IBS.

There are quite a number of errors in that chart.

The references below were written by the Australian researcher who did the original work on fructose malabsorption and later FODMAPs for managing IBS and other functional GI disorders. They did a detailed chemical analysis of many common foods to determine their safety for individuals with fructose malabsorption.

Oranges and pure orange juice are fine because it has equal amounts of glucose and fructose. In fact navel oranges have about 2 grams of fructose and 3.2 grams of glucose per 100 grams. I drink a glass or so each day. I am just going to have a glass of Florida OJ before my morning 1 km swim

Ginger root is fine too. It has about 0.1 gram of fructose and 0.45 grams glucose per 100 grams. Of course it is high in insoluble fiber.

Stevia an artificial sweetener that does not contain any fructose and it isn't a polyol. It is not mentioned in any article on fructose malabsorption or FODMAP diet by a knowledgeable author. The problem with asking people if they have problems with stevia is that this product frequently contains FOS which is a problematic fructan. Many individuals don't read the label they just assume a product maybe pure stevia.
