Where is fibre found?
Dietary fibre is found in cereals, fruits and vegetables. Fibre is made up of the indigestible parts or compounds of the plant that pass relatively unchanged through our stomach and intestines, although bacteria in the large intestine can partly digest fibre through fermentation. Other terms for dietary fibre include ‘bulk’ and ‘roughage’ – which can be misleading, since some forms of fibre are water soluble and aren’t bulky or rough at all. There are broadly two categories of fibre and we need to eat both in our daily diets: Soluble fibre – includes pectins, gums and mucilage, which are found mainly in plant cells. One of its major roles is to lower blood cholesterol levels. Good sources of soluble fibre include fruits, vegetables, oatbran, barley, seed husks, flaxseed, psyllium, dried beans, lentils, peas, soymilk and soy products. It can also help with constipation. Insoluble fibre – includes cellulose, hemicelluloses and lignin, which make up the structural parts of plant cell wall
