Fibre forms the skeletal system of plants. Without it no plant or tree would be able to stand upright. Dietary fibre, the roughage of yesteryears, consists of those parts of the plant foods that cannot be digested by enzymes or other digestive secretions in the alimentary canal.

Dietary fiber plays an important role in the maintenance of health and prevention of diseases. There is sufficient evidence to suggest that an artificial depletion of fibre as in case of refined cereals and sugar has over the last 100 years contributed to several degenerative diseases.

Recent studies in this area indicate that sufficient intake of fibre-rich diet may help prevent obesity, colon cancer, heart disease, gallstones, irritable bowel syndrome, and diabetic conditions.

Physiological Effects:

  • Fibre in the diet promotes more frequent bowel movements and softer stools having increased weight.
  • The softness of stools is largely due to the presence of emulsified gas which is produced by the bacterial action on the fibre.
  • A high fibre intake results in greater efficiency in the peristaltic movement of the colon.

  • This helps in relieving the constipation which is the main cause of several acute and chronic diseases.
  • Recent studies suggest that increasing the dietary fibre intake may be beneficial for patients with irritated bowel syndrome who have diarrhoea and rapid colonic transit, as well as to those who have constipation and slow transit.
  • The high fibre diet, like bran, thus regulates the condition inside the colon so as to avoid both extremes – constipation and diarrhoea.Investigations have shown that several potential carcinogens are produced in the faeces. Their production is related to the acidity of the gut content.
  • The greater the acidity in the bowel content, the less is the production of these carcinogens.
  • The breaking down of the fibre by bacteria renders the faeces more acidic.
  • This reduces the amount of possible carcinogenic substances.
  • Fibre also reduces the possibility of formation of harmful toxins in the large intestine by reducing the intestinal transit time of the food contents.
  • Dietary fibre increases the bacteria in the large intestines which require nitrogen for their growth.
  • This in turn reduces the chances of cancerous changes in cells by reducing the amount of ammonia in the large bowel.
  • Fibre reduces the absorption of cholesterol in the diet. It also slows down the rate of absorption of sugars from the food in the digestive system.
  • Certain types of fibre increase the viscosity of the food content. This increased viscosity indirectly reduces the need for insulin secreted by the pancreas.
  • Thus a fibre-rich diet can help in diabetes mellitus.

Sources of Fibre:

The most significant food sources of fibre are unprocessed wheat bran, whole cereals such as wheat, rice, barley, rye, millets , legumes such as potato, carrots, beet, turnip and sweet potato,fruits like mango and guava and leafy vegetables such as cabbage, lettuce and celery.
