Core Tip
Core tip: Despite the importance of enteral nutrition (EN) for patients, diarrhea is a common complication in those receiving EN. Meta-analysis conducted in this review revealed that fiber supplementation in EN reduces diarrhea incidence. However, the positive effect is only seen in stable patients, and is not observed in critically ill patients. In addition, the effect of fiber and prebiotic supplementation towards fecal microbiota and short-chain fatty acids remain disputable due to the mixed findings. The heterogeneity of study populations, antibiotics therapies, and variation of the dosage for fiber and prebiotics likely explain such outcomes.
