Why is gut health important?

Gut health describes the physiological function and balance of bacteria of the many parts of the gastrointestinal tract. The gut microbiota is the name given to the microbe population living in our intestine that contains tens of trillions of microorganisms, including at least 1000 different species of known bacteria. The composition of gut microbiota is unique to each individual and the first few years of life are major for microbiota establishment.
