Running or exercising improves our gut microbiota.

Our guts are full of life. Competing for space and food in our gastrointestinal tract are about 100 trillion bacteria, viruses, fungi and other single-celled organisms such as archaea and protozoa.

Its functions range from helping to ferment the dietary fiber in our food to synthesizing vitamins and regulating our fat metabolism.

They also help protect us from unwanted invaders by interacting with our immune system and influencing the level of inflammation in our gut or other parts of our body.

Less diversity of these intestinal inhabitants is observed in patients suffering from obesity, cardiometabolic diseases and autoimmune diseases.
