Cooking legumes

Including Legumes on a Low FODMAP Diet_408f2a50

By Dr. Caroline Tuck - Research Dietitian

Research is currently underway to look at ways we can make it easier for patients with IBS to follow a low FODMAP diet. One strategy that our group is looking at is if changing the way we cook foods can reduce the FODMAP content, hence potentially making it easier to people to tolerate them. 


The main FODMAPs present in legumes are the oligosaccharides. Oligosacchardies are water soluble, which means that when the food is put into water, the oligosacchardies can leach out of the food and into the water. At Monash University, we have recently been testing if any reduction in FODMAP content will occur through this process. We have found that when legumes e.g. red lentils are boiled in water, the liquid they are cooking in becomes higher in oligosacchardies.


This has shown that straining legumes after cooking may help to reduce their FODMAP content. This is a great strategy to trial at home to see if it helps you tolerate legumes better and increase your legume intake.
