It is important that we get enough fiber from our diet, because it helps to support healthy digestion, weight management, blood sugar regulation and much more. It has been linked to longevity and a decreased risk of cancer.
The indigestible parts of plant-based foods are referred to as dietary fiber. Men aged 50 and under should aim for 38g of fiber per day, while those over 50 should aim for 30g. Women aged 50 and under should get 25g, while those over 50 should get 21g. The average American consumes just 15g of fiber per day.

The passage of food through the GI tract can be sped up by insoluble fiber. It helps to maintain regularity. It attracts water into your stools, making them easier to pass.
Most plant-based foods contain both insoluble andsoluble fiber, but the amounts of each vary in different foods.
Good sources of fiber include:

A recent animal study suggested that fiber might only cause this benefit if a person has the right amount of gutbacteria. Fiber can ferment into a chemical called butyrate, which can cause cancer by making cancer cells self-destruct. A high-fiber diet can help encourage the growth of the butyrate- producing bacteria in some people.
Some scientists think fiber could help people live longer. A meta-analysis of relevant studies published in the American Journal of Epidemiology concluded that high fiber intake may reduce the risk of mortality.
Scientists have been puzzled by the existence of a role that fiber could play in preventing food allergies. The interaction between fiber andbacteria in the gut is what this theory is about.
Scientists theorize that people aren't producing the right gutbacteria to tackle foods that are associated with allergies. Particles of these foods can enter the bloodstream if the rightbacteria are not present. Clostridia is a bacterium that helps keep the gut secure.
Fiber might help people with asthma. Particles escaping the gut and entering the bloodstream can cause inflammation. A study published in Nature Medicine found that mice on a high-fiber diet were less likely to have asthma.

A low-fiber diet is sometimes required for medical reasons. According to the University of Pittsburgh Medical Center, those undergoing surgery, radiation or chemotherapy often need a rest. People suffering from diseases such as diverticulitis, inflammatory bowel disease and ulcerative colitis can often maintain a low-fiber diet.
