The human gut plays host to a multitude of microorganisms: bacteria, archaea, yeasts, single-celled
eukaryotes, as well as helminth parasites and viruses, including bacteriophages, collectively referred to as
the microbiota. The interaction between the bacteria and host is mutually beneficial with the bacteria
involved in energy regulation, gut barrier function, protection from pathogens, and immune system
function amongst others, while the host provides the nutrients and environment in which the bacteria can
In the gut there is a real "second brain" that bidirectionally communicates with the first brain. At the center
of this communication is the bacterial population residing within the gastro-intestinal tract. This population
can affect our emotions. This system uses several lines of communication with the central nervous system:
essentially the bloodstream and the vagus nerve. Dysbiosis of the gut bacteria communities can cause
many chronic diseases, such as inflammatory bowel disease, obesity, cancer and autism. In the case of
Leaky Gut Syndrome, an alteration of gut permeability, the translocation of bacterial products (in particular
inflammatory cytokines) which pass through blood brain barrier into the blood, is mechanism responsible
for behavioral changes.
