Fibre is a type of carbohydrate that our body does not digest. Instead, fibre is fermented by bacteria in the gut. In this way, there is a lot of overlap between foods that are high in fibre and foods that are high FODMAPs. However, there are many different types of fibres and therefore the FODMAP levels will differ. It is important to eat adequate amounts of fibre-containing foods while you are on a low FODMAP diet
to avoid constipation. One example of a low FODMAP fibre is guar galactomannan/PHGG (partially hydrolysed guar gum).
