Even though fibre is not absorbed it is very important.

#### **Function**

- Helps the digestive system work and prevents constipation and bowel cancer.

#### **Sources**

- Found in most plant matter e.g. vegetables, fruit and cereals. The cellulose from the plant's cell walls (not present in animal cells) is not easily digested by humans but is a good source of fibre.
