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.

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.

I don't know, the chart actually makes a lot of sense based on my past experiences with oranges, ginger and stevia. I do buy 100% pure stevia and it gives me a similar reaction though not as intense, as if I were to have sorbitol or sucralose. Also, this ginger drink Ive bought on many occasions also makes me sick. I had asked you once and you said the rest of the ingredients were fructose safe. Orange juice doesnt seem to be too much of a problem with one glass a day but more than that it does.
Why do you think this chart listed these as things to avoid if it is incorrect? They must of got the info somehow, hwree do you think it came from and how do we know what is correct and incorrect?

Yea for me I think stevia is on the avoid list. I can not be sure that it is from fructose malabsorption I suppose but makes a lot of sense seeing it on this chart. A I said in my other post, it gives me a similar reaction as does sorbitol and sucralose so makes sense it would be the fructose malabsorption.

They way one knows what is and is not correct is to read and understand the information written by knowledgeable individuals who developed the understanding of the physiology involved and apply it to their patient base. Unlike functional GI disorders like IBS the physiology of fructose malabsorption is quite well understood. The difficulty is finding reliable chemical analysis of foods that give accurate fructose and glucose content. That is the reason the Australian research prepared the information given in the two references in my previous response.
The second reference in my signature and the two references given in the previous email are some examples of excellent information sources. Google searches are unreliable because there is plenty of misinformation on the web. If you are in doubt then you should talk to a knowledgeable GP or GI doctor
As for ginger it is high in insoluble fiber it does not have excess fructose. It is easy to confuse IBS triggers foods with excess fructose foods when you have both fructose malabsorption and IBS.

Syl,
your references are paid articles.
My chart would certainly need a revision by an experienced dietitian. You can see from that chart that it tends to be overly strict and I would move some foods from red to green area.

why do you think then that I react to stevia and ginger juice (not root)? It jsut seems like it would make sense it may have something to do with the fructose malabsorption especially since it is documented in several charts. Did you ever try these yourself? Possibly its not the fructose content but something else that is similar among those with FM?

Problems with stevia could be due to something else but it is unrelated to fructose content since stevia does not contain any fructose - it contains steviol glycosides . Some of the additives in Stevia products might. A chemical analysis of ginger root clear shows it does not have excess fructose. What else was in your ginger juice?

They are articles published in regular subscription medical and scientific journals that you can access for free at a university library. Or if you belong to a university then you can access them on-line. Most of the reliable research information on FM and FODMAPs are found in these journals. Once in a while the author of these articles will post them on their institutional web site such as the Gibson and Shepherd article - the second reference in my signature - and you can get them without a subscription or going to a university library. Otherwise due to copyright restrictions you have to get them from a source such as a university library that subscribes to these journals or buy them on-line.
The first reference in my signature was written by a dietitian with knowledge about FM and FODMAPs. It is quite good. Although she says citrus fruits such as oranges & grapefruits contain polyols which is not confirmed in the references I listed in the previous message. There maybe polyols in the skins but they are not ingested.
