Oh how fabulous fibre is. We've all heard about dietary fibre and that we need to eat more of it, but why exactly is it important? Keep reading and I will fill you in on what fibre is, what it does (why it's so wonderful), and provide you with 25 different ways to help you reach your 25g/day of fibre.  

So, what is dietary fibre? 

Dietary fibre is a component of plant materials that passes through our stomach and small intestine relatively unchanged, as humans lack the enzymes to break it down (1). It is then fermented by the friendly bacteria in our gut. Fibre is not broken down and used as fuel like other carbohydrates, but instead acts as a sort of sponge, which along with sufficient water, helps to clean out our intestine. Sufficient dietary fibre and water, can help remove waste from our colon, provide food for our friendly gut bacteria and keep our digestive systems happy and healthy.

How much do I need?

It is recommended that females over the age of 19yrs eat around 25g/day and males eat 30g/day of fibre (1). 

Why is it important? 

Eating a diet rich in dietary fibre can help reduce the risk of constipation, diverticular disease, haemorrhoids, bowel cancer, and may also reduce the risk of cardiovascular disease (2).  

There are three types of fibre, which we need to eat daily, and these are insoluble and soluble fibre, and resistant starch. Most plant foods contain a mix of both soluble and insoluble fibres so if you're enjoying a variety of plant foods on a daily basis you're likely getting both of these in your diet, however, resistant starch can be harder to come by. 

Insoluble fibre acts mainly as a bulking agent for stools and it helps to clear food and waste out of the gut. Insoluble fibres are the structural parts of the plant walls, and passes through the digestive system mostly intact. Insoluble fibres help to keep us full, and are important for good bowel health. Good sources of insoluble fibre are wholegrain foods, fruits and vegetables (especially the skins), nuts, seeds, beans and bran. 

Soluble fibres mix with water in our intestines, and form a gel that slows the rate of digestion. This can help people feel fuller for longer, and can help stabilise blood glucose levels in people with diabetes (2). Soluble fibres may also help to lower total and LDL (bad) cholesterol levels (3). Good sources of soluble fibre include beans, oats, flaxseed, psyllium, fruits, vegetables and soy products. 

Resistant starch is the part of starchy foods that acts similarly to dietary fibre, and resists digestion in the small intestine. It then moves to the large intestine where it is fermented by the friendly bacteria that live there, and is changed into short-chain fatty acids, which plays an important role bowel health (4). Resistant starch is found in under ripe bananas, under-cooked or al dente pasta, cooked and cooled potatoes and rice, uncooked oats and legumes (5). Here is a short animation explaining why resistant starch is good for you.   

Reaching your 25g/day (or 30) sounds hard, but it can actually be quite simple and super delicious, as long as you know what to be filling up on. I've put together 25 ways to help you reach your fibre intake, have a look and see what you could do to meet this target.
