The term "gut microbes" refers to the various types of bacteria, viruses, fungi and other microorganisms that live in our digestive system. These tiny organisms play a crucial role in maintaining good health by helping us break down food, producing vitamins, regulating immune responses, and even influencing moods and emotions. The balance of gut microbes can be affected by factors such as diet, stress, antibiotic use or other environmental influences, which may lead to an imbalance that could result in health issues like digestive problems, obesity, autoimmune diseases or even mental health disorders.
