Fibre is an essential part of a balanced diet.
It not only helps provide fuel for gut bacteria, but it is also vital for maintaining healthy, frequent bowel movements.
These foods are all high in fibre, and are an easy way to meet your daily fibre recommendation of 30g/day.
There are also many other ways of ensuring high fiber intake such as eating lots of whole grains and eating whole fruits and vegetables rather than juices.
Hope this helps!
