Strategies for Modulating the Gut Microbiome

The human gastrointestinal tract (GIT) is home to a vast array of microbes that play a crucial role in human health and disease. The balance between Bacteriodetes and Fermicutes, two major groups of gut bacteria, is particularly important for maintaining intestinal health. Among the trillions of bacterial species living in symbiosis with the human digestive tract, Bifidobacterium, Lactobacillus, Blautia, Akkermansia, Roseburia, Fecalibacterium, and Eubacterium are dominant groups that support GIT well-being. However, slight changes in the gut’s working mechanisms or the host immune response can cause various gastrointestinal conditions, such as coeliac disease, type 2 diabetes mellitus, and inflammatory bowel disease (IBD). To prevent these gastrointestinal disturbances, experts recommend several strategies for modulating the gut microbiome, including the addition of required macronutrients and micronutrients to the diet, oral administration of synthetic prebiotics, probiotics, and faecal microbiota transplantation. Additionally, certain vegetables, fruits, and cereals are excellent sources of flavonoids, lignans, and phenolic acids that aid in gut microbiome modulation. These innovative strategies have proven to be effective in maintaining gut homeostasis, retaining gut barrier integrity, and promoting the health of the human GIT.
