Have you ever had a gut feeling or butterflies in your stomach?
These sensations emanating from your belly suggest that your brain and gut are connected.
What’s more, recent studies show that your brain affects your gut health and your gut may even affect your brain health.
The communication system between your gut and brain is called the gut-brain axis.
This article explores the gut-brain axis and foods that are beneficial to its health.
