Improved digestion with fiber -
Some very high-fibre breakfast cereals may have around 10g of fibre per serve. If this cereal is not accompanied by enough fluid, it may cause abdominal discomfort or constipation. Many adults do not consume enough fibre — on average, most Australians consume 20—25g of fibre daily.
Make sure you stick to the recommended intake and slowly introduce fibre into the diet to avoid any negative outcomes. A sudden switch from a low-fibre diet to a high-fibre diet may lead to some abdominal pain and increased flatulence wind.
Also, very high-fibre diets more than 40g daily are linked with decreased absorption of some important minerals such as iron , zinc and calcium. This occurs when fibre binds these minerals and forms insoluble salts, which are then excreted.
This could result in an increased risk of developing deficiencies of these minerals in susceptible people. Also, it is better to get fibre from food sources rather than from fibre supplements, as these can aggravate constipation, especially if you do not increase the amount of water you drink daily.

Types of dietary fibre There are 2 categories of fibre — soluble and insoluble. What is soluble fibre? Soluble fibre includes pectins, gums and mucilage, which are found mainly in plant cells.
Good sources of soluble fibre include: fruit and vegetables oat bran, barley, seed husks, flaxseed, psyllium legumes — dried beans, lentils, peas soy milk and soy products. What is insoluble fibre? Good sources of insoluble fibre include: bran — wheat bran, corn bran, rice bran the skins of fruits and vegetables nuts and seeds dried beans wholegrain foods.
Resistant starch acts like fibre Resistant starch, while not traditionally thought of as fibre, acts in a similar way. Sources include: many unprocessed cereals and grains unripe bananas potatoes lentils added to bread and breakfast cereals.
It can also be formed by cooking and manufacturing processes such as snap freezing. Health benefits of dietary fibre The digestive system is lined with muscles that massage food along the digestive tract — from the moment a mouthful is swallowed until the eventual waste is passed out of the bowel a process called peristalsis.
It also important for other body functions, such as: lowering blood cholesterol keeping our weight under control stabilising glucose — which is important if you have diabetes reducing our risk of other conditions such as heart disease and some cancers.

Insoluble fiber attracts water to the intestine , which adds bulk to stool and promotes the movement of waste products through your digestive system. It can be extremely beneficial for people who struggle with constipation and irregularity.
Good sources of insoluble fiber include:. Here are some tips from Harvard T. Chan School of Public Health for incorporating more fiber into your diet.
Fiber supplements are another simple way to increase your fiber intake, though they are not intended to completely replace high-fiber foods. Supplements are just that — supplementary — and should be used to amplify, not substitute for a high-fiber diet.
Acknowledging the connection between fiber and a flourishing gut microbiome is the first step on a journey toward optimal gut health. A thriving gut, in turn, lays the groundwork for overall health and well-being. Additional reporting by Megan Mikaelian.

Health Conditions A-Z. Soluble fiber found in oat bran, barley, nuts, seeds, peas and some fruits and vegetables absorbs water, which transforms it into a gel-like substance that slows digestion.
In contrast, insoluble fiber speeds digestion by adding bulk to the stool; it's found in whole grains, wheat bran and some types of vegetables. It also feeds the good kind of bacteria in your colon to produce short chain fatty acids, one of which is butyrate.

Fiber lowers breast cancer risk - particularly when young women eat a fiber-rich diet.
Scientists have long been aware that eating plenty of fiber helps lower women's risk of developing breast cancer, in part by binding to estrogen; a hormone known to cause breast cancer developments.
