Dietary treatments for childhood constipation: Efficacy of dietary fiber and whole grains
Department of Human Nutrition, Food, and Animal Science, University of Hawaii at Manoa, Honolulu, Hawaii, USA.Nutrition Reviews (Impact Factor: 6.08). 02/2013; 71(2):98-109. DOI: 10.1111/nure.12010
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.

ABSTRACT: The changes in physicochemical and physiological properties of modified soluble dietary fibre (mSDF) in the okara using enzymatic [cellulase/substrates ratio of 2.0–6.0% (w/w) at 50 °C for 90–150 min], chemical [water bath of 1–3 h, water bath temperature of 50–90 °C, Na2HPO4 concentration of 0.1–0.9% and sample/reagent radio (S/R) of 1:40–1:60 (w/v)] and physical (homogenised once or twice under the optimal cellulase treatment condition) treatments were evaluated. The mSDF yield with chemical treatment (57.16%) was significantly (P < 0.05) higher than that of physical treatment [homogenisation once (16.54%) or twice (42.02%)] in combination with cellulase treatment. All treatments improved swelling capacity of mSDF and promoted bile acid- and cholesterol-absorption capacity, but enzymatic and chemical treatments decreased the total reducing power of mSDF, except homogenisation-cellulase treatment (141.74 μm TE g−1). Therefore, homogenisation-cellulase treatment may be the appropriate method to improve the SDF proportion and ameliorate the functionality of okara.International Journal of Food Science & Technology 08/2015; DOI:10.1111/ijfs.12929 · 1.38 Impact Factor
