Ah - ha - It nice to know who wrote that article. It is a pleasure to meet you. Glad to hear you will try to fix some of deficiencies. It would be helpful to those of us with FM.
If you check the second reference in my signature by Gibson and Shepherd which is a more recent article they say "Thus, fructose malabsorption manifests when free fructose (i.e. in excess of glucose) is in the lumen. This is the reason why fructose supplied in the form of sucrose is only malabsorbed if sucrase activity is diminished." In addition they say that foods with > 3 g per fructose per serving are termed a 'high fructose load' and possibly at-risk of inducing symptoms. They go on to say that the concept of a 'high fructose load' has not been evaluated in terms of its importance in the success of the FODMAP diet. I believe so far the clinical research has not supported the supposition about sucrose.
