In relation to Gut Health, what dual role does the significant Dietary Fiber in broad beans perform?

Adding bulk to stool to prevent constipation and acting as a prebiotic to feed beneficial gut bacteria

The high content of dietary fiber found in broad beans benefits the digestive system through a critical two-pronged approach. Firstly, the physical structure of the fiber—the roughage derived from the skin and internal bean matrix—adds necessary bulk to the stool. This increased volume is essential for regulating intestinal motility and preventing constipation by ensuring smooth transit time through the digestive tract. Secondly, and equally important for long-term health, fiber serves as a prebiotic. Prebiotics are non-digestible food components that selectively stimulate the growth and activity of beneficial bacteria residing within the gut microbiome. A robust and well-supported gut flora is subsequently linked to enhanced immune response and improved overall systemic well-being.
