About this Research Topic
Dietary interventions are enjoying a renaissance in functional gastrointestinal disorders (FGIDs) management due to the clear clue between diet intervention and gut microbiota shaping. Among these, a plant-source bio-compounds enriched diet is an important therapeutic option for functional GID, which has a long tradition, with different approaches in different regions of the world, some of which have made their way into modern evidence-based medicine. Plant natural products are a plethora of diverse and complex molecules produced by the plant's secondary metabolism. The most well-known common products derived from plants and used in the fight against constipation, inflammation and even cancer are polyphenols/flavonoids, polysaccharides/oligosaccharides and polyunsaturated fatty acids, i.e., resveratrol, curcumin, anthocyanins, konjac glucan, inulin, α-linolenic acid, etc.
Current research has focused on discovering associations between these natural plant compounds from gastrointestinal disorders. The changes in the microbiota composition of GIDs patients with different symptoms usually varied from each other, and the metabolite changes reflected in the fecal or serum metabolome might imply the precise indicators for disease-specific mechanisms. Great efforts have been engaged in characterizing the microbiome to effectively demystify the interaction between the plant compounds or derivatives with the intestinal microenvironment including the microbiome and gastrointestinal cells as well. Various studies have reported that various plant natural products are capable to regulate the gut microbiota, indicating the potential to be used as an alternative strategy to improve gut dysbiosis and assist disease therapy or prevention. Concurrent and iterative longitudinal studies in humans and animals need to be done to investigate the precise microbial metabolites and their functions, which could be applied to address specific pathophysiological mechanisms in GIDs.
The focus of this Research Topic is to provide a platform for research into the use of plant products for various gastrointestinal disorders targeting gut microbiome restoration. Research on the minimum (synthetic) community and the interactions that are required to achieve restoration and to better understand the community responses that result in symptom remission is encouraged.
We welcome submissions including, but not limited to, the following topics:
• The regulatory mechanism of natural compounds from plants on the gut microbiome (such as promoting the beneficial bacterium or inhibiting the potential pathogen ) in the disease prevention and treatment
• Characterization of the novel protective effects of natural plant compounds or derivatives against gastrointestinal disorders
• Exploration of the protective mechanisms of natural plant compounds or derivatives from the aspects of oxidative stress, inflammatory stress, gut dysbiosis, intestinal mucosal barrier, metabolomics, transcriptomics, proteomics, etc.
• Exploration of the synergic effects of probiotics and natural plant compounds on host gut health and nutrition
Keywords: gastrointestinal disorders, natural compounds, microbiome
