Our gut - the unrecognized genius

Our intestines are home to the largest population of microorganisms on earth. Up to one trillion protozoa per gram live in the large intestine in particular. This diverse ecosystem plays a crucial role in our metabolism and immune system and is known as the intestinal flora or microbiome. Without these microorganisms, we would not be able to live, as they digest our food and convert it into vital substances. The diversity of these single-celled organisms is crucial for optimal digestion and nourishment of our body.
