Interactions between diet and gastrointestinal microbiota influence health status and outcomes. Evaluating these relationships requires accurate quantification of dietary variables relevant to microbial metabolism, however current dietary assessment methods focus on dietary components relevant to human digestion only. The aim of this study was to s...

Hospital placement is essential training for medical interns, involving shift work and high-pressure environments. This can increase physiological and psychological stress, which may be mediated by metabolites of microbial digestion(1). Nutrients of interest include those accessible to microbial digestion and associated with altered signalling with...

Background and Aims Diet plays an integral role in the modulation of the intestinal environment, with the potential to be modified for management of individuals with inflammatory bowel disease (IBD). It has been hypothesised that poor “Western-style” dietary patterns select for a microbiota that drives IBD inflammation and that through dietary inte...

Introduction: The irritable bowel syndrome (IBS) is the best recognized disorder of gut brain interactions (DGBI). However, it is controversial if the Rome IV criteria iteration for IBS diagnosis is fit for purpose. Areas covered: This review critically evaluates Rome IV criteria for diagnosis of IBS and addresses clinical considerations in IBS...

Aims: To explore consumer perceptions regarding dietary behaviours related to the gut microbiome, to assist in effective translation of research to practice. Methods: Online focus groups were conducted (adults with no formal medical or nutrition training). Semi-structured open-ended questioning explored perspectives related to gut health and die...

Aims: This study aimed to explore dietitians' perspectives on the evidence surrounding the relationship between diet and 'gut health' and the current and emerging role of dietetics practice in this area. Methods: A qualitative descriptive methodology was used. Online semi-structured interviews were conducted with Australian dietitians, focused o...

Context Cereal fiber modulates the gut microbiome and benefits metabolic health. The potential link between these effects is of interest.0 Objective The aim for this systematic review was to assess evidence surrounding the influence of cereal fiber intake on microbiome composition, microbiome diversity, short-chain fatty acid production, and risk...
