The human microbiome refers to the vast community of microorganisms, including bacteria, viruses, fungi, and other microbes, that live in and on the human body. These microorganisms are primarily found in areas such as the gut, skin, and mouth, and they play a crucial role in maintaining health by aiding digestion, supporting the immune system, and protecting against harmful pathogens. Research on the human microbiome has revealed its significant impact on various aspects of health, including metabolism, mental health, and disease susceptibility. Factors such as diet, lifestyle, and environment can influence the composition of the microbiome, highlighting its dynamic nature and importance in overall well-being.
