What is the Gut-Brain Axis?

Written by Aanandita Mahavadi

Have you ever felt “butterflies” in your stomach before going on stage in front of a large audience? Well that sensation is the connection between our gut and brain,This connection is known as the Gut-Brain Axis as it links our bodies central nervous system(CNS) and gastrointestinal (GI) tract.This connection involves the vagus nerve, hormones and the gut microbiome, which is a collection of trillions of microorganisms that live in the digestive tract.

The microbiome plays a key role as it produces neurotransmitters like serotonin and dopamine, which influence mood and cognition. About 90% of the body's serotonin is produced in the gut. Research has shown how imbalances in the gut microbiome are linked to mental health disorders like anxiety and depression, as well as some physical conditions like irritable bowel syndrome(IBS).

Scientific research shows how a healthy gut directly impacts one's mood and brain function. A diet rich in fiber, fermented foods, and probiotics help maintain a balanced microbiome, which supports one's mental and physical being. For example, foods like yogurt, kimchi, and bananas, nurture beneficial bacteria which enhances the connection between one's gut and brain.

The gut brain axis demonstrates how interconnected our body actually is. By caring for your gut you are also taking steps to do things like support your mental health. It's a powerful reminder that shows how our lifestyle choices can greatly affect our overall well being.
