Insoluble fibre is the kind of fibre that is not digested by the body (for example skins, pips, husks, bran and nuts), these are not absorbed from the gut but stays behind in the gut and helps with bowel movement and to clean out the gut.
Soluble fibre (found in the flesh part of fruits and vegetables as well as oats) are digested in the gut and forms a gel that delays gastric emptying thereby lowering the GI value of the meal to help control blood glucose levels. Soluble and insoluble fibre each has a special function in the body so make sure consume plenty of both!
Quick tip: Eating a fruit with its skin on is an easy way to consume both soluble and insoluble fibre all in one!
