Pre and Probiotics to Postbiotics: A Changing Paradigm

Abstract

The relationship between microbiota and human health has long been stated by Hippocrates said, “Death sits in the bowls” in 400 B.C. With recent scientific advance ments, there is a growing understanding of the significance of microbiota in health and disease. The two-way communication between the host and the microbiota involves the production of various metabolites that play crucial roles in host energy metabolism, influence nervous system function and the gut- brain axis, immune maturation and homeostasis, maintenance of mucosal integrity, treatment of metabolic disorders, anti-obesity, cholesterol lowering, antioxidant, anticancer, antiproliferative and anti-inflammatory properties. Postbiotics are inanimate microorganisms or their compounds, including short-chain fatty acids, exopolysaccharides, vitamins, teichoic acids, bacteriocins, enzymes and peptides that provide health benefits to the host. Postbiotics can be stored under normal environmental conditions, have a prolonged shelf life, easy to transport, and handle and overcome the limitations of probiotic use. As a result, postbiotics have immense potential as a safe and effective means of promoting health and well-being.
