Soluble fibre soaks up toxins and waste in the digestive system Insolube fibre (”roughage”) moves bulk through the intestine to help with regular bowel movements.

This group of muscles acts like a gate to prevent stomach acid from going back up (refluxing) into the oesophagus. Stomach: Gastric juice contain HCl and gastric enzymes. Hydrochloric acid (HCl) helps to digest proteins and other foods by pepsin enzymes while minimizing harmful bacteria.
