What is Rice Fibre?

Rice fibre is a versatile, plant-derived ingredient often used to to increase dietary fibre intake. It is a naturally derived dietary fibre obtained from rice, typically from the outer layers of the grain or from purified rice plant material.

Health Benefits:

Helps Increase Fibre Intake

While it is not a concentrated source of vitamins or minerals, rice fibre can contribute to digestive health and help consumers achieve recommended daily fibre intakes. Fibre plays a vital role in gut health and is well recognised for its contribution to normal bowel function by increasing stool bulk and promoting regularity.

May Support Gut Microbiome Health

It addition to its benefits for bowel movement, rice fibre may support healthy gut microbiome function. Some components of rice fibre may be fermented by beneficial bacteria in the large intestine, contributing to the production of short-chain fatty acids which can strengthen the intestinal barrier, reduce inflammation, have immunoregulatory action and facilitate critical communication between the gut and the brain.

Could Help Regulate Blood Sugar

Increasing your fibre intake, such as through the consumption of rice fibre, may help regulate blood sugar levels. For example, it has been suggested that insoluble fibre can absorb both glucose and enzymes to prevent excess glucose being available to enter the bloodstream, helping prevent blood sugar spikes. Furthering this, short chain fatty acids, like those produced through the fermentation of fibre, have been linked to anti-diabetic effects such as improving insulin sensitivity and attenuating insulin resistance.

Typical use:

Rice fibre is a widely used ingredient used within products such as baked goods, functional foods, plant-based products, supplements and protein powders. There is a long history of the use of rice fibre for its beneficial effects. For example, some ancient Asian folk practices involved giving extracted rice bran or bran-infused water, which are rich in rice fibre, to those suffering from digestive discomfort to soothe sensitive stomachs and support gut motility.
