why should we include adequate source fibres in our diet
Answers
Dietary fibre is found in cereals, fruits and vegetables. Fibre is made up of the indigestible parts or compounds of plants, which pass relatively unchanged through our stomach and intestines. Fibre is mainly a carbohydrate. The main role of fibre is to keep the digestive system healthy.
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.
Benefits of fibre
Dietary fibre is mainly needed to keep the digestive system healthy. It also contributes to other processes, such as stabilising glucose and cholesterol levels. In countries with traditionally high-fibre diets, diseases such as bowel cancer, diabetes and coronary heart disease are much less common than in Western countries.
Most Australians do not consume enough fibre. On average, most Australians consume 20–25 g of fibre daily. The Heart Foundation recommends that adults should aim to consume approximately 25–30 g daily.
Children aged between four and eight should consume 18 g of fibre each day. Girls aged 9 to 13, and 14 to 18 years, need 20 g and 22 g per day respectively. Boys aged 9 to 13, and 14 to 18 years, need 24 g and 28 g per day respectively.
Disorders that can arise from a low-fibre diet include:
constipation
irritable bowel syndrome
diverticulitis
heart disease
some cancers.
