The microbiome refers to the collection of trillions of microorganisms, including bacteria, viruses, fungi, and other microbes, that live in and on the human body. These tiny organisms play a crucial role in various bodily functions, such as digestion, immune response, and even mental health. The composition of an individual's microbiome can be influenced by factors like diet, environment, and genetics. Research has shown that a healthy microbiome can contribute to overall well-being, while an imbalance may lead to health issues, such as obesity, diabetes, and inflammatory diseases. Scientists continue to study the microbiome to better understand its impact on health and how it can be manipulated for therapeutic purposes.
