The incredible complexity of the gut and its importance to our overall health is a topic of increasing research in the medical community. Numerous studies in the past two decades have demonstrated links between gut health and the immune system, mood, mental health, autoimmune diseases, endocrine disorders, skin conditions, and cancer.
At one time, our digestive system was considered a relatively “simple” body system, comprised essentially of one long tube for our food to pass through, be absorbed, and then excreted.
The term “gut microbiome” refers specifically to the microorganisms living in your intestines. A person has about 300 to 500 different species of bacteria in their digestive tract. While some microorganisms are harmful to our health, many are incredibly beneficial and even necessary to a healthy body.
According to Dr. E. M. Quigley in his studyTrusted Source on gut bacteria in the Journal of Gastroenterology and Hepatology, having a wide variety of these good bacteria in your gut can enhance your immune system function, improve symptoms of depression, help combat obesity, and provide numerous other benefits.
