In recent years, gut microbiota as an immune organ has gradually become the mainstream of research. When the composition of the gut microbiota was changed significantly, which may affect human health. This review details the major microbiota composition and metabolites in the gut, and discusses chronic diseases based on gut dysbiosis, including obesity, liver injury, colon cancer, atherosclerosis, central nervous system diseases. Comprehensively summarizes changes in abundance of relevant gut microbiota by ingesting different diet components, such as food additives, dietary polyphenols, polysaccharides, fats, proteins, and influence on microbial quorum sensing (QS) system, thereby regulating related diseases. We believe that QS can be used as a new entry point to explain the mechanism of ingesting dietary components to improve gut microbiota and thereby regulate related diseases. This review hopes to provide a theoretical basis for future research on improving disease symptoms by ingesting functional foods containing dietary components. This article is protected by copyright.
