We’ve asked Elouise Rice, a dietetic student at Queen Margaret University, to give us the low down:
The gut-brain axis
There is a communication system between your gut and brain which is referred to as the gut-brain axis. This connection is bi-directional, meaning the gut can communicate with the brain and vice versa (1). They are connected both physically and biochemically. The gut is often referred to as the “second brain” as it has such an influence over our brain (2).
A classic example of this communication pathway is having ‘butterflies’ in your stomach when we are feeling anxious or nervous. The gut-brain axis has also been linked to many diseases and disorders such as obesity (3), Irritable Bowel Syndrome (4), depression and anxiety (5).
