What is Fibre?

Dietary fibre (also known as roughage) is the part of food that cannot be easily digested.

Fibre is not digested in our small intestine – it moves into our colon or large intestine where some of it will be broken down. Fibre also helps our stools form a 鈥榖ulk鈥 and makes them solid.

Different Types of Fibre:

There are two main types of fibre: soluble and insoluble fibre.

Soluble fibre is easily digested in our large intestines/colon and dissolves with water to form a gel. For example:

路聽聽聽聽聽聽 porridge oats

路聽聽聽聽聽聽 the flesh of fruits e.g. apples, pears, bananas

路聽聽聽聽聽聽 root vegetables

 

Insoluble fibre passes through our body without being broken down or absorbed. For example:

路聽聽聽聽聽聽 the skins, pips and seeds of fruit and vegetables

路聽聽聽聽聽聽 fibrous fruits and vegetables e.g. rhubarb, celery

路聽聽聽聽聽聽 raw or undercooked vegetables

路聽聽聽聽聽聽 vegetables that humans are unable to digest e.g. mushrooms, sweetcorn, lettuce and other salad leaves

 

An example of the two different types of fibre can be seen in a tomato.

Soluble fibre is the fleshy part of the tomato. This will dissolve in the large intestine and helps to add bulk to stools.

Insoluble fibre is the skin and seeds of the tomato. These are the parts that are not possible for your gut to digest.

 

What is a low fibre diet?

A low fibre diet is one that will help you to reduce the volume and frequency of your stool. It also lengthens the time food passes through your gut.

 

How long will you need to follow this diet?

These changes are usually only recommended for a short period of time. Your Dietitian will follow your progress and advise you on the next stage of your treatment.

 

What foods do you need to avoid?

Some foods need to be completely avoided. These include the pips, skins and seeds of fruits and vegetables, wholegrains, pulses and beans, which are not easily digested. The tables on pages 3-7 provide detailed lists.

 

What fruit and vegetables can you eat?

When you follow a low fibre diet you need to limit how many fruit and vegetables you eat. You must aim to have no more than 1 portion of fruit and 1 portion of vegetables each day.聽 聽A portion is roughly 80 grams, or the equivalent of a handful. Always choose from the 鈥榝oods allowed鈥 lists.
