I hope this will help you....



The main reason fibre is beneficia,
That it feels the "good" bacteria in the intestine
Did you know that your body is really just 10% human ?

That's because the bacteria that live
in the body out number the body cells 10
to 1 .


bacteria live on the skin, in the mouth and nose.. but the great majority leaves in the gut, primarily the large intestine .

There are about 500 different species of bacteria living in the intestine tota number about 100 trillion.The bacteria in the gut are also known as a gut flora.

This is not a bad thing .. there is a mutually
beneficial relationship between us humans and the bacteria. We provide the bacteria with shelter and safe -habbit, instead they take care of some things that the human body can't do this on it's own.

There are many different kinds of bacteria .and the type .(different species) of bacteria have a dramatic effect on various aspects on health, including weight, blood sugar control, immune function and brain function .

But what does that have to do. with
fibre ?
Well ...like other organisms, bacteria need to eat. They need to get energy from somewhere in order to survive and function .

The problem is that most carbs,
proteins and fats get absorbed into the bloodstream before they make it to the large intestine. There is nothing left for
the get flora.
this is where fibre steps.. in humans don't have the enzyme to digest fibre and therefore it reaches the large intestine relatively unchanged .


However, the intestinal bacteria DO
have the enzymes to digest many of
these fibres .

This is the most important reason
that (some) dietary fibres are important for health .They need the "good "bacteria ,which can have barriers positive effects on health .


The friendly bacteria produce nutrients
for the body including short- chain fatty acids like acetate , propionate,butyurate, of which butyraty appears to be the most Important.

The short -chain fatty acids can feed the cells in the colon, leading to reduce inflammation in the gut and improvement in various digestive disorders like irritable bowel syndrome ,crohn's disease and ulcerative colitis .

when the bacteria ferment the fibre ,they also produce gases. This is the reason high fibre diet can cause flatulence and stomach discomfort but this usually goes away with time as your body adjusts.

Answer 2

Here's the answer

Fibres are indigestible substance. They are thrown out along with other useless and undigested matter. This aids in egestion. Some fibresalso helps in digestion of other substances.

Green leafy vegetables , fruits , cereals , etc are considered as important diet as they supply nutritious fibres.

Thus, Fibres are one of the important nutrients.
