Did you know that the enteric nervous system (ENS – the nervous system that controls the functions of the gut) has half a billion neurons – that’s five times the amount than in your spinal cord – which is why the gut is often referred to as “the second brain”? 90% of your “feel good” hormone, serotonin, and 50% of your dopamine is also located in the gut. The food you eat alters the response of your enteric nervous system, and this can have large impacts on your entire body.
