“Gut bacteria both produce and respond to the same neurochemicals—such as GABA, serotonin, norepinephrine, dopamine, acetylcholine and melatonin—that the brain uses to regulate mood and cognition. Such neurochemicals probably allow the brain to tune its behavior to the feedback it receives from the army of bacteria in the gut.“
It is estimated that 90-95% of serotonin is produced in the gut. Therefore, it is difficult to reason that inflammation and imbalance stemming from the gut do not affect the brain. In countless cases, rebalancing the gut not only benefits the brain but demonstrates protection from chronic diseases such as Alzheimer’s disease.
