The gut microbiota are very important for the host health because they play role in degradation of non-digestible polysaccharides (fermentation of resistant starch, oligosaccharides, inulin) strengthening gut integrity or shaping the intestinal epithelium, harvesting energy, protecting against pathogens, and regulating host immunity.
S. mutans is the main component of the oral microbiota. [15] A healthy oral microbiome decreases oral infections and promotes a healthy gut microbiome. However, when disturbed, it can lead to gum inflammations and bad breath. [16] Dental plaque is formed when oral microorganisms form biofilms on the surfaces of teeth.

The most common environment concerning their effects on human health is the gastrointestinal tract, where prebiotics can alter the composition of organisms in the gut microbiome. Dietary prebiotics are typically nondigestible fiber compounds that pass undigested through the upper part of the gastrointestinal tract and help growth or activity of ...
