What are FODMAPs?

FODMAPs are small sugars and fibres (aka. carbohydrates) found in some of the foods we commonly eat.  They are often poorly absorbed and easily fermented by the bacteria in the gut (thus the name fermentable). They are like fast food for the bacteria in our gut.

Saccharide means sugar

Oligo = a few sugars joined together

Di = two sugars joined together

Mono = one sugar

Polyols are sugars with a little alcohol unit attached (not to be confused with alcoholic drinks)

Why do these Sugars Cause a Problem?

These poorly absorbed sugars cause IBS symptoms in two ways

1: THEY ATTRACT WATER INTO THE GUT.

The small sugars attract water into the gut, which increases the total volume and, which then stretches the gut wall. 

2: RAPID FERMENTATION

Bacteria in the gut ferment the small sugars and this fermentation produces gas, which again stretches the gut wall.

The Combined Effect of FODMAP Foods

These small sugars can also have a combined effect, which is why the amount of each FODMAP that is eaten with each meal is important. We’ve got you covered though, portions sizes are part of the phase 2 reintroduction.
