with gastrointestinal symptoms who has fructose malab- sorption. The proportion of patients receiving EN who have fructose malabsorption has not been investigated. One-third of 82 healthy volunteers with no or minimal gastrointestinal symptoms could not absorb a load of fructose, and this proportion increased to 1 in 2 of 80 patients with Crohn’s disease.34 In other words, it is common for patients not to be able to absorb a load of fructose, as delivered by means of many enteral formu- lae. There has been no research undertaken investigat- ing whether FODMAP content of enteral feeds is a cause of gastrointestinal complications, but anecdotal experience and theoretical considerations point to FODMAPs as important triggers for such symptoms in patients receiving EN.
