What is the specific mechanism by which insoluble fiber, found in the feijoa, aids digestive health?

Answer

It acts as a bulking agent, adding mass to stool to promote regularity

Feijoa fruit contains two types of beneficial fiber, and insoluble fiber performs a structural role in the digestive tract. Its primary function is to act as a bulking agent. By adding physical mass and substance to the stool, it helps facilitate smoother and more consistent transit through the digestive system. This bulking action is key to preventing sluggish digestion and is directly responsible for promoting regularity and helping to prevent constipation, which is distinct from the metabolic and cholesterol-binding roles played by soluble fiber.
