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.
