What to know about fructose
Fructose is the sugar at the centre of the condition called fructose malabsorption. Pure crystalline fructose is all free fructose with no glucose to help carry it across the gut wall, so it is the textbook excess-fructose FODMAP. When the small intestine cannot keep up, the rest ferments in the colon and causes bloating, gas, cramping and diarrhoea.
Watch for
- The definitional excess-fructose FODMAP: with no glucose alongside it, absorption fails easily and symptoms follow
- A frequent trigger for bloating, wind, cramping and diarrhoea in anyone with fructose malabsorption, even in small amounts
- Poorly suited to SIBO, where the extra fermentable sugar feeds bacterial overgrowth
