The Connection Between Gut Health and Mental Health

Did you know . . . ? 

There is a bi-directional ‘superhighway’, or communication network, between the gut and the brain, via the vagus nerve. This complex bidirectional communication network includes the central nervous system (brain), the autonomic nervous system (sympathetic and parasympathetic systems), and the enteric nervous system (the gut).¹

This gut-brain axis influences various physiological, metabolic, and psychological processes, and health or disease in one can affect the other. Communication from the gut (enteric nervous system) to the brain (central nervous system) is largely influenced by the microbiome (the trillions of bacteria, fungi, parasites, and other microorganisms that live in our gut.) A healthy microbiome plays a crucial role in our overall health, as well as our mood and mental health.

Disruptions in the gut’s microbiome, known as dysbiosis, can lead to dysregulation of the gut-brain axis, which has been implicated in the development of mood disorders such as anxiety and depression. Many factors can contribute to dysbiosis such as diet and lifestyle, as well as psychological stressors.

Interestingly, over 90% of serotonin, a key neurotransmitter involved in mood regulation, is produced in the gut. Other neurotransmitters are produced in the gut as well, such as GABA. 

Support your gut’s ecosystem with plenty of fiber and polyphenols from colorful fruits and vegetables, seeds, and legumes; prebiotics such as asparagus, mushrooms, Jerusalem artichokes, onions, garlic, bananas, and flaxseeds; reduce intake of ultra-processed foods and refined sugar; manage stress with mindfulness practices; enjoy daily movement; and get 7-9 hours of restorative sleep every night.
