PREBIOTICS AND POSTBIOTICS

Abstract

The phrases "prebiotics" and "postbiotics" are used to refer to various gut microbiota-related elements and outcomes. Prebiotics are certain dietary fibres that can withstand digestion and act as a food supply for good bacteria in the colon. They are not degraded by stomach acid or mammalian enzymes, and they pass through the digestive system undigested. The idea of prebiotics was first proposed in the early 1900s when scientists discovered that probiotic microorganisms produced advantageous substances through the fermentation process. Postbiotics, on the other hand, are the leftovers from microbial metabolism or the deactivated parts of bacteria. They can consist of a variety of compounds, including lactic acid, bacteriocins, and teichoic acids. Antibiotics may Postbiotics can directly affect the host, affecting a variety of biological functions. Postbiotics have an immediate effect on the host, whereas prebiotics primarily act as food for good bacteria. They may have antibacterial traits that prevent the development of harmful microorganisms and dislodge biofilms. Postbiotics may also affect the general health of the gut by altering the gut flora. Although "postbiotics" became a common name in the late 20th century, the basic idea and study findings date back further. As a result, prebiotics and postbiotics are separate substances with discrete functions in the gut flora. Prebiotics and postbiotics both participate in the intricate and dynamic interactions that take place inside the gut environment, which have an impact on general health and wellbeing.
