What is the evidence for addition of fiber to tubefed patients?

• A. Addition of fiber to tubefeeding consistently reduces diarrhea
• B. There is clear consensus that fiber should be avoided
• C. Addition of fiber to tubefeed has shown less diarrhea and firmer stools, but benefits are not consistently shown
• D. Fiber addition worsens constipation

Answer: (C)

Adding fiber to tubefed patients can influence stool form and diarrhea because soluble fibers absorb water and slow transit, while fermentable fibers support gut bacteria and produce short-chain fatty acids that help with stool consistency. In trials with tube-fed patients, fiber addition has been associated with less diarrhea and firmer stools. However, findings are not consistent across all studies or settings, and benefits can depend on the type and amount of fiber, the specific formula, and patient factors. So there is evidence of potential benefit, but it is not uniformly demonstrated, making fiber supplementation something to tailor and monitor rather than a universal standard.
