The trillions of microbes that live in the human digestive system are collectively referred to as the gut microbiota, or "tummy gold.". Fungi, viruses, bacteria, and other unicellular organisms make up this intricate ecosystem. Digeromeo all gamestion, metabolism, & immune system regulation are just a few of the many biological processes that depend on the gut microbiota. According to recent studies, there may be a link between the gut microbiota and mental health issues like anxiety, depression, and autism spectrum disorders. Numerous factors, such as dietary practices, environmental exposures, genetic predisposition, and lifestyle choices, influence the composition of an individual's gut microbiota.
