So, fibre’s digestion-journey begins in your mouth. Special enzymes in your saliva start to break down the carbohydrates that carry the fibre. The food then travels down your oesophagus, the tube between your mouth and stomach.
Once in your stomach, the fibre starts to mix with partially-digested food, creating a thick paste that can pass easily through the rest of your gastrointestinal tract.
The fibre continues through into the small intestine, passing through undigested.
Food moves from your small intestine, into your large intestine - also known as the colon. This is the site where fibre does a lot of heavy lifting! Less fermentable fibre increases bulk helping move waste material through the gut. More fermentable types act as a food source for the bacteria living here; with prebiotic fibre specifically targeting important bacteria, fibre’s adventure is almost over.
