What is resistant starch?

Resistant starch is a form of starch that is not fully broken down and absorbed in the small intestine. It passes through the small intestine intact and is then fermented in the large intestine. As a result, it is classified as a type of dietary fibre.

Resistant starch is naturally present in foods such as bananas, potatoes, grains, pulses and seeds. It can also be produced and added into some food products for its functional properties. It has a low calorie content (approximately 2 kcal/gram).

Experts from the European Food Safety Authority recommend a daily intake of 25 grams of dietary fibre for normal bowel function in adults. In addition, scientific evidence shows that there are health benefits associated with higher intakes of dietary fibre in adults (e.g. reduced risk of heart disease and type 2 diabetes, and weight maintenance).
