For Dr. Mercola's many articles on fructose, look here.
"As a standard recommendation, I strongly advise keeping your TOTAL fructose consumption below 25 grams per day.
For most people it would also be wise to limit your fructose from fruit to 15 grams or less, as you're virtually guaranteed to consume "hidden" sources of fructose if you drink beverages other than water and eat processed food. Remember, the average 12-ounce can of soda contains 40 grams of sugar, at least half of which is fructose, so one can of soda ALONE would exceed your daily allotment.
Fifteen grams of fructose is not much -- it represents two bananas, one-third cup of raisins, or two Medjool dates. In his book, The Sugar Fix, Dr. Johnson includes detailed tables showing the content of fructose in different foods -- an information base that isn't readily available when you're trying to find out exactly how much fructose is in various foods."

"Comparison of the prevalence of fructose and lactose malabsorption across chronic intestinal disorders" in Aliment Pharmacol Ther. (2009)
"Early rise in breath hydrogen after lactulose occurred more commonly in healthy controls (39%) than in Crohn's disease (20%) and untreated coeliac disease (14%; P < 0.008) ...Fructose malabsorption was more frequent in Crohn's disease (61%) than other groups (33-44%, P < 0.05). ... In Crohn's disease, concurrent Fructose malabsorption and lactose malabsorption was most common (29%), and the association of fructose malabsorption with ERBHAL seen overall (62%) was not observed (36%, P < 0.0001). CONCLUSIONS. Carbohydrate malabsorption and ERBHAL are normal physiological phenomena. The abnormal patterns observed in Crohn's disease may have pathogenic importance."
