What's the difference between insoluble and soluble fibre?
Insoluble and soluble fibre function very differently in the body and both are needed as part of a healthy diet. Insoluble fibre, like wheat bran fibre, doesn't dissolve in water. This is beneficial because it increases the bulk or weight of undigested food material and and speeds up the movement of this material through the digestive system helping to promote regularity.
Soluble fibre is fibre that dissolves in water. When mixed with water in your body, the fibre turns into a gel-like substance. Generally, soluble fibres contribute to healthy blood cholesterol levels and regulate blood sugar levels.
