The gut microbiota is a complex ecosystem of microorganisms, including bacteria, viruses, fungi and other microbes, that colonize our gastrointestinal tract. These microorganisms play a fundamental role in digestion, nutrient absorption and the functioning of the immune system. In addition, they contribute to maintaining body homeostasis and preventing the proliferation of pathogens. The composition of the gut microbiota varies between individuals and is influenced by multiple factors, such as diet, genetics, environment and lifestyle [1].
