The intestinal system has an autonomous brain called the “abdominal brain”

70% of our immune system cells reside in the gut

The human body contains more bacteria than human cells (>100 Trillion (10¹⁴))

Every person has 500 to 1000 different types of intestinal bacteria in his/her gut

The whole intestinal bacteria of a person are called gut flora or intestinal microbiome

The composition of the gut flora is highly dynamic and influenced by nutrition

The composition of our gut flora might be an important factor for being underweight or overweight

Digestion of nutrients, vitamins and minerals is positively influenced by a healthy gut flora

Intestinal infections with pathogenic yeasts or enterobacteria very often result in a disbalanced gut flora

Repeated antibiotic treatments are amongst the most frequent events that damage our gut flora
