Potentials of Probiotics in Food

This book chapter is primarily concerned with the potentials of probiotics in food, the most popular probiotic food, probiotic microorganisms, their health advantages, the probiotic mechanism, and clinical applications. Probiotics are a colony of bacteria that inhabit our intestines and are thought of as a metabolic “organ” due to their positive impact on human health, including the immune system and metabolism. Probiotics may significantly affect immune, digestive, and respiratory processes. According to recent scientific research on the characteristics and functionality of living microorganisms in food, they may substantially contribute to preventing infectious diseases in children and other high-risk populations. Probiotics are present in many products on the market, and their potential applications are expanding daily, primarily because some probiotic strains support the health of the gut microbiota, particularly Firmicutes and Bacteroidetes, and may prevent certain gastrointestinal tract (GIT) issues. Probiotic supplements usually contain lactic acid bacteria, bifidobacteria, and yeast. These beneficial bacteria may out-compete pathogens, regulate the gut microbiota, and have anticancer, antiobesity, and antidiabetic properties. Probiotics may affect immunological activity by boosting innate and adaptive immune responses, changing the microbial habitat in the intestine, enhancing gut barrier function, promoting competitive adhesion to the mucosa and epithelium, and generating antimicrobial chemicals. Probiotics can also prevent coronavirus disease 2019 (COVID-19) infections, according to recent studies. There are now many more probiotic foods and beverages available to customers that are thought to have health benefits.
