The microbiota plays an important role in health and disease, including GC. Dysbiosis of gut microbiota has been reported to be associated with various diseases.

A meta-analysis was performed by searching the PubMed, Web of Science, EMBASE, and Cochrane Library databases up to July 2022. Nine eligible studies, representing 405 patients, were included in the analysis. At the phylum level, Proteobacteria (mean difference 12.46 (3.06–21.87), p < 0.05) was significantly increased, and Firmicutes (mean difference −4.10 (−7.65 to −0.56), p < 0.05) was decreased in patients with GC. At the genus level, <em>Desulfovibrio</em> (mean difference 0.38 (0.16–0.59); p < 0.05) and S<em>treptococcus</em> (mean difference 1.92 (0.37–3.46), p < 0.05) were significantly increased in patients with GC. No significant difference was observed in gut microbial diversity between patients and non-GC controls. Subgroup analysis suggested that region, sample size, and quality of studies caused heterogeneity to different extents. In summary, our study indicated a difference in gut microbial composition between patients with GC and individuals without GC. No significant differences were observed in the diversity of the gut microbes.

Accompanying that, the incidences of inflammatory bowel disease (IBD), allergy, and other autoimmune diseases are steadily increasing over the past 60 years, especially in high-income countries, which is partly attributed to the changing dietary habit in modern societies. Chronic inflammation triggered by immune disorders is the central part of the pathophysiology of various non-communicable diseases. Dietary fiber intake is inexorably linked to the gut microbiome leading to the reduction of inflammation. This review explores how dietary fibers modulate the gut microbiota composition and function leading to the alteration of host physiology. High-fiber dietary regime has been consistently shown to increase the microbiome alpha diversity and short-chain fatty acids (SCFAs)-producing bacteria in the human gut. SCFAs are the main players in the interplay between diet, microbiota, and host health. In clinical settings, therapies with high fiber or SCFA supplementations are proposed for inflammatory diseases. However, due to greater variations in the dosage, type, and duration of dietary fiber intervention in different clinical trials, the effects remain controversial. Unraveling the mechanisms exerted by dietary fiber in synergy with the gut microbiome in human pathophysiology holds a promising prospect in guiding next-generation precision therapies.</p></div>","PeriodicalId":36019,"journal":{"name":"Medicine in Microecology","volume":"14 ","pages":"Article 100070"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590097822000209/pdfft?md5=f6a038dfbd725fe802b3ba373fe9d515&pid=1-s2.0-S2590097822000209-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41378563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
