Fibre and enteral nutrition.

Systematic review and meta‐analysis: the clinical and physiological effects of fibre‐containing enteral formulae

“…hydrolysed guar gum or finely ground soy polysaccharide) to reduce feed viscosity and minimize the risk of feeding tube occlusion. This may alter its biological characteristics, such as water‐holding capacity, fermentability (which increases when soy fibre is finely ground), and the pathways by which they are metabolized 86 . Highly fermentable substrates generally have less faecal bulking effect than poorly fermentable substrates, such as cellulose and bran 6 .…”

Pectin-Supplemented Enteral Diet Reduces the Severity of Methotrexate-Induced Enterocolitis in Rats

“…The effect of pectin on reestablishment of the mucosal mass was much greater in the colon than that in the small bowel in our study. This may be related to the fact that pectin is mainly fermented to SCFAs in the cecum and colon (35,36), and colonic cells depend largely on the luminal fermentation products. Thus, pectin, by providing luminal nutrients to the colon, plays a great beneficial role for colonic mucosa.…”

Pathophysiology of Enteral Feeding Diarrhea: The Intestinal Responses to Enteral Feeding Rather Than Any Role of FODMAPs

“…The results of our studies demonstrated that the ascending colonic secretion observed during intragastric enteral feeding is reversed when SCFAs are infused directly into the cecum 20 . The major source of SCFA production in the ascending colon is the anaerobic metabolism of unabsorbed polysaccharide or “fiber” by bacterial polysaccharidase enzymes 21 . It seemed to us that the reversal of colonic secretion was a strong argument in favor of altering the composition of polymeric enteral diets to include a rapidly fermentable fiber source as a means of preventing the onset of enteral feeding–related diarrhea.…”
