Fibers are one of the important nutrients.Give scientific reasons

Answer 1

Hi,hope this helps you...
The Main Reason Fiber is Beneficial, is That it Feeds 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 outnumber the body's cells 10 to 1.

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

There are about 500 different species of bacteria living in the intestine, total number about 100 trillion. The bacteria in the gut are also known as the 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 a safe habitat, instead they take care of some things that the human body can not do on its own.

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

But what does that have to do with fiber?

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 gut flora.

This is where fiber steps in... humans don't have the enzymes to digest fiber and therefore it reaches the large intestine relatively unchanged.

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

This is the most important reason that (some) dietary fibers are important for health. They feed the "good" bacteria in the intestine, functioning as prebiotics.

That way, they increase our levels of the "good" bacteria, which can have various positive effects on health.

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

These short-chain fatty acids can feed the cells in the colon, leading to reduced inflammation in the gut and improvements in various digestive disorders like Irritable Bowel Syndrome, Chron's disease and Ulcerative colitis.

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