Health benefits of probiotic bacteria

Probiotic bacteria have become progressively admired during the last few decades as a result of the steadily developing scientific evidence pointing to their helpful effects on human health. Hence, they have been used as different products with the food industry. Probiotic bacteria are the heterogenous group of bacteria, which play prominent role in maintaining human health. Humans are the major reservoir of heterogenous group of microbes which can modify the host internal habitat and hence play a dominant role in host health. Supplementation with probiotics has shown remarkable results against various pathogenic microbes because of their distinctive ability to compete them for adhesion sites, nutrients, or producing some antagonistic compounds to eliminate pathogens. Thereby regulate the host immune responses by stimulating the activation of specific genes in host. The present review documents the concept and the possible beneficials of probiotic bacteria, focusing its availability in food items.
