HYDERABAD: Fifty grams of biomass or bacteria in the fecal matter is an indication that there is enough fibre in the diet. But even this quantum has not been reached, according to studies of stool undertaken regarding many human populations.
This is because people have consumed medium and fully processed foods, said Dr John H. Cummings, emeritus gastroenterologist, who delivered the 42nd Gopalan Oration Award.
Dr Cummings explained how in 1966 dietary fibre was a part of traditional foods. With processed foods taking over, the intake of fibre had reduced drastically.
The importance of die-tary fibre is now being felt in the society as it is a natural protector against heart diseases and cancer. The intake of dietary fibre ensures that there is enough water and allows the passage of food in the digestive track smoothly.
Various studies of poop conducted over the years have shown that those who had foods rich in dietary fibre had larger stools, those who had less had medium stools and those who had minimal or no fibre had small and hard stools.
The transit period from the intake to the outlet was measured and it was found that those who had good intake of dietary fibre their food was digested in 24 hours.
But those who had less intake had a longer period of time in transition of food and it could range from one and a half day to three days.
These various experiments carried out in controlled groups where their stools were studied have shown that dietary fibre plays a major role in the passage of food. Earlier nutritionist studied fibre for animal foods and it was considered a major part of animal nutrition.
To decrease the burden of diseases, research nutritionist stated that whole grains and dietary fibres are an important component in the food plate.
