A high-fibre personalised dietary advice given via a web tool reduces constipation complaints in adults

Constipation can greatly impact the quality of life (QoL), which can be relieved by dietary fibres; however, preserving a higher fibre intake remains a challenge. We investigated the effects of a personalised dietary advice (PDA) on fibre intake and mild constipation complaints. A total number of twenty-five adults with mild constipation...

Increasing dietary fibre intake in healthy adults using personalised dietary advice compared with general advice A single-blind randomised controlled trial

Objective: A high-fibre diet is associated with a lower risk for diseases. However, few adults meet the dietary fibre recommendation. Therefore, the effects and acceptance of an algorithm-generated personalised dietary advice (PDA) compared with general advice (GA) on fibre intake were investigated. Design: A 6-week, single-blind randomised...

Dietary fibre: Challenges in production and use of food composition data

Dietary fibre is a heterogeneous group of components for which several definitions and analytical methods were developed over the past decades, causing confusion among users and producers of dietary fibre data in food composition databases. An overview is given of current definitions and analytical methods. Some of the issues related to...

Propionic acid affects immune status and metabolism in adipose tissue from overweight subjects

Background Adipose tissue is a primary site of obesity-induced inflammation, which is emerging as an important contributor to obesity-related diseases such as type 2 diabetes. Dietary fibre consumption appears to be protective. Short-chain fatty acids, e.g. propionic acid, are the principal products of the colonic fermentation of dietary fibre...

Effects of dietary fibre intake during adolescence on the components of the metabolic syndrome at the age of 36 years: The Amsterdam Growth and Health Longitudinal Study

Background: The prevalence of the metabolic syndrome is increasing, especially in young individuals. Most of the previous studies that have investigated the association between dietary fibre intake and the metabolic syndrome are cross-sectional or of short duration, and their results are inconsistent. The present study investigated whether...

Subchronic (13-week) oral toxicity study in rats with fungal chitin-glucan from Aspergillus niger

Chitin-glucan is an insoluble biopolymer, composed of chitin and beta-(1,3)-d-glucan, that is a component of the fungal cell wall. This study was conducted to assess the safety of chitin-glucan from the mycelium of Aspergillus niger (Artinia™ brand) for use as dietary supplement and food ingredient. Chitin-glucan was fed to Wistar rats (20/sex...

The effect of particle size of wheat bran fractions on bread quality - Evidence for fibre-protein interactions

The nature of the adverse effects of wheat bran fractions on bread-making quality was studied. Two fractions of bran, representing different tissue layers and having different compositions, were used. The particle size of the bran fractions was varied by various milling techniques. All fractions were added to white flour and water addition was...

28-Day oral toxicity study in rats with high purity barley beta-glucan (Glucagel™)

Beta-glucans are glucose polymers present in cereal grains, particularly barley and oat. Consumption of these grains or concentrated beta-glucan preparations has been shown to lower blood cholesterol. The present study was conducted to assess the safety of a high purity (>75%) barley beta-glucan (Glucagel™). The product was fed to Wistar rats (5...
