  10. Fibre – it’s a very good thing!

  11. Fibre and the digestive system • The body cannot digest fibre – it forms the bulk to help bowel movement • It absorbs water – keeps the faeces soft/prevents constipation • Soft faeces easily pass through the digestive system – so fibre helps the flow in the digestive system • Small hard faeces do not pass easily through the colon, which causes ruptures in the intestine. The inner lining of the colon is pushed and distorted, causing diverticular disease • Fibre helps to prevent various bowel disorders/bowel cancer/appendicitis/piles
