Fibre – What is it and why do we need it?
Fibre is one of those things we don’t really think much about, particularly for kids. It’s not an elegant nutrition topic, but fibre is a very important part of the diet for people of all ages!
What is dietary fibre?
Fibre is the part of a plant food which is not broken down by our bodies during digestion. It is found in foods such as wholegrains, fruit, vegetables, beans and legumes. It is essential for a healthy digestive system and preventing diseases like diabetes, heart disease & bowel cancer. Our gut plays a huge role in our overall health, which is why eating high fibre foods has a wide range of benefits.
Did you know that most Australians do not consume enough dietary fibre? Here’s how much we should be having each day:
There are two different types of dietary fibre – soluble fibre and insoluble fibre. They each have different functions and health benefits, and are both present in most plant foods.
Soluble fibre is found in oats, barley, nuts, seeds, lentils, fruits & vegetables. This fibre slows down digestion and helps us to stay fuller for longer. Soluble fibre stabilises our blood sugar levels, and can lower cholesterol reabsorption.
Insoluble fibre keeps us regular and the whole system running smoothly. Insoluble fibre is also super filling! It can be found in cereal brans, the skins of fruit & vegetables, nuts, seeds, and wholegrain foods.
Resistant Starch works like fibre by resisting digestion in our small intestine and travels on to our large intestine where it acts as a prebiotic, meaning it feeds the good bacteria that keeps our gut healthy. Resistant starch can be found in pasta served al dente, in bananas that aren’t too spotty, plantains, cooked and cooled potato, and ‘hi maize’ (found in commercial foods like breads and cereals).
