What is soluble fibre?

Soluble fibre is defined as a type of dietary fibre that dissolves in water to form a gel-like substance. This characteristic enables it to absorb water and creates a viscous solution in the digestive tract, which can aid in regulating blood sugar levels and lowering cholesterol. Soluble fibre is found in foods such as oats, legumes, fruits, and some vegetables, and it plays a crucial role in digestive health.

The unique ability of soluble fibre to dissolve in water distinguishes it from other types of dietary fibre, like insoluble fibre, which does not dissolve and contributes primarily to bulk in stools and helps promote regular bowel movements. Soluble fibre's interactive properties with water and its fermentation by gut bacteria also contribute to health benefits, such as improved gut microbiota.

Understanding the distinction between soluble and other forms of fibre is significant for grasping how different types of fibre affect digestion and overall health.
