**3.2 Dietary fibre**

Dietary fibres are classified under complex carbohydrates found in plants, and are undigested in the small intestine but undergo fermentation by colonic flora [24]. This fibre is made up of non-starchy polysaccahrides which are found in fruits, vegetables, wholegrains or cereals, legumes (such as beans and lentils), plantains and tubers. Dietary fibres from pectin, guar, and oat bran are highly fermentable, while those from wheat bran and cellulose are poorly fermentable.
