Dietary treatments for childhood constipation: efficacy of dietary fiber and whole grains

Abstract

Constipation in children is defined on the basis of several clusters of symptoms, and these symptoms are likely to persist into adulthood. The aim of this review article is to summarize the current literature on the use of dietary fiber and whole grains as treatments for childhood constipation. Current recommendations for fiber intake in children vary substantially among organizations, suggesting that the function of fiber in children is not fully understood. Additionally, no formal definition of "whole grain" exists, which further complicates the interpretation of the literature. Few randomized controlled trials have examined the effect of dietary fiber supplementation in children with constipation. Currently, no randomized controlled trials have investigated the efficacy of whole grains in treating childhood constipation. This is an area that warrants further attention. Increasing the intake of dietary fiber and/or whole grain has the potential to relieve childhood constipation; however, additional randomized controlled trials are necessary to make a formal recommendation.

The immune-regulating effect of Xiao’er Qixingcha in constipated mice induced by high-heat and high-protein diet

“…Previous studies have suggested that unhealthy diets involving HHPD and low-fiber diet predisposed children to constipation [7, 17]. In this follow-up study, we endeavored to further explore the potential beneficial effect of EXQ on two constipated mice models, named HHPD model and HHPD + atropine model, which mimicked pediatric constipation due to HHPD and in combination with poor gastrointestinal mobility.…”

“…Constipation may result of dietary, metabolic and painful anorectal condition; however, unhealthy dietary habits are most common cause in children [6, 7]. As the life quality improved, parents tend to seek refined and high-nutrition diets for their children.…”

“…Studies have suggested that unhealthy diets, especially HHPD and low-fiber diet are crucial predispositions in pediatric constipation [7, 17]. And, one striking characteristic of chronic constipation is low-grade inflammation in mucosa [18], which is frequently observed after low-fiber diets [19].…”

Nutritional Supplements and Functional Foods

“…The main components of natural plant foods are often different kinds of fiber [47À49]. Dietary fibers and whole grains have been used in treatment of childhood constipation as well [51]. Dietary fiber also increases the volume of the gut contents.…”

Modification of insoluble dietary fibres in soya bean okara and their physicochemical properties

“…Many studies had shown that SDF exhibited higher cholesterol‐ and sodiumcholate‐binding capacity (Nsor‐Atindana et al ., ), and it can be used to reduce blood pressure, prevent gastrointestinal problems and protect against several cancers, such as breast cancer, colorectal cancer and prostatic cancer (Chawla & Patil, ). It can also ameliorate constipation (Stewart & Schroeder, ), be taken as a partial substitution of lipid (De Moraes Crizel et al ., ) and has anti‐inflammatory activity on the digestive tract (Andoh et al ., ). In addition, DF has the antioxidant effect, especially in cereal which is rich in ferulic acid (FA), and it is related to the absorption of phenolic compounds, but the action of intestinal esterases on DF‐bound phenolic acid is facilitated on the SDF.…”
