Insoluble fibre is a type of dietary fibre that does not dissolve in water. It plays a vital role in human health by providing bulk, or roughage, which supports regular bowel function and helps accelerate the removal of potentially harmful substances from the digestive tract.1

Key food sources of insoluble fibre include:

Whole grain breads and cereals1
Wheat bran1
Vegetables1

These foods contain components such as cellulose, lignin, and most hemicelluloses, which contribute to the insoluble fibre content of your diet. Consuming adequate fibre is important for overall health, as it helps delay glucose absorption and may provide protection against various chronic and gastrointestinal diseases.1
