We read numerous articles on the internet where there is a lot of emphasis on gut health in general.
This is not just about digestive health or specific gut issues but your overall health.
The gut microbiome represents the bacteria in our gut. These include both good and bad bacteria.
The good bacteria maintain a healthy gut flora while the bad bacteria damage it.
There are several studies which have proven the connection between our gut microbiome and brain.
This connection takes place via 3 pathways in our body. These include immunoregulatory pathway, neuroendocrine pathway and the vagus nerve pathway.
The immunoregulatory pathway includes the microbiota interacting with immune cells which affects the level of inflammatory markers namely cytokines and prostaglandins.
The neuroendocrine pathway includes the enteroendocrinal cells affects the function of hormones via the hypothalamic-pituitary axis and the central nervous system by regulating the levels of cortisol, tryptophan and serotonin.
The neurons of the myentric plexus inside our intestine are exposed to gut microbiota and regulate gut hormone secretion via motor neurons in the intestine. This intestinal nervous system forms connection with the vagus nerve.
Toxic metabolic bi-products like lactic acid and ammonia produced by the gut bacteria can pass through the vagus nerve and into our brain which its functions and ultimately our sleep.
This takes place primarily via intestinal permeability which increases when the barrier is damaged or leaking.
Cell division required for repairing a “leaky gut” occurs at night that is in the absence of light. That is why chronic blue light at night and a lack of sunrise circadian syncing exacerbates gut issues.
So maintaining a healthy gut via a nutritious diet is essential.
