Which statement describes the role of insoluble fiber?

• A. Promotes regularity
• B. Dissolves in water
• C. Regulates blood sugar
• D. Increases weight loss

Answer: (A)

Insoluble fiber mainly increases stool bulk and speeds intestinal transit, which helps promote regular bowel movements. It doesn’t dissolve in water, so its primary effect isn’t dissolving in the gut or forming gels like some soluble fibers do. While fiber can support weight management and soluble fibers can help regulate blood sugar by slowing absorption, the standout role of insoluble fiber is to support regularity through added bulk and faster transit.
