Examples of fermentable and bulking (non-/poorly fermentable) plant-based fibre

Fermentable fibreNon-/poorly fermentable fibre*
Fruits and vegetables (soluble polysaccharides. Sources: garlic, onion, leeks, chicory root, asparagus, bananas, beans, dairy products)
Grains (soluble polysaccharides such as glucan. Sources: oats, barley)
Inulin (sources: fruits, vegetables, herbs, wheat)
Soy polysaccharide (source: soybean)
Gum arabic (source: gum of the Acacia tree)		Wheat bran
Oat bran/hull
Cellulose
Lignin
Alginate
Methylcellulose

  • *Dependent on the extent of processing (eg, milling) which may increase the fermentability of fibre.
