Recent breakthroughs in neuroscience have revealed an incredibly complex communication network now known as the ‘gut-brain axis.’ It turns out that the trillions of bacteria residing in our digestive systems – collectively known as the microbiome – are not just passive passengers; they play a critical role in regulating our mood and cognitive functions. Scientists have discovered that the gut produces approximately 95% of the body’s serotonin, the primary hormone responsible for stabilising our mood and feelings of well-being.

This biological link explains why we often experience ‘butterflies’ in our stomach when we are anxious or ‘gut feelings’ when making a decision. Because the gut and brain are in constant dialogue via the vagus nerve, what we eat directly impacts how we think and feel. Consequently, diet is being radically reconsidered by the medical community. It is no longer just a tool for physical fitness, but is increasingly seen as a primary intervention for mental health conditions such as depression and anxiety. Future treatments for low mood may involve psychobiotics – specific bacteria designed to improve the mind through the stomach.
