You are never alone. Even now, reading this text, you are in the company of trillions of small “roommates”. This is your microbiome. For a long time, we considered bacteria to be enemies, but modern science proves: they are our best friends, controlling almost all processes in the body: from immunity to the ability to enjoy life.

You’ve probably heard the phrase: “We are what we eat.” But modern science says it more precisely: we are also those who live in us. Until 2016, it was believed that there were many times more bacteria in our bodies than our own cells.

Today, the gut is called our “second brain” and a super organ, as it houses over 75% of the body’s immune cells. Our gastrointestinal tract is home to thousands of species of microorganisms that determine our eating habits, immune responses, weight, and even mood.
