Insoluble fibre does not dissolve in water but is essential for maintaining digestive health. It adds bulk to stool and helps move material through the digestive system.
Common sources of insoluble fibre include whole grains, nuts, seeds, and the skins of fruits and vegetables such as apples, pears, and potatoes. Unlike soluble fibre, which absorbs water to form a gel, insoluble fibre focuses on improving stool consistency and ensuring the smooth functioning of the digestive tract, reducing the risk of blockages.
Additionally, insoluble fibre contributes to gut health by supporting a balanced environment for beneficial bacteria and can enhance feelings of fullness.
