Can we fix our mental health epidemic with a drastic change in what we eat? That's the question posed by Professor Julia Rucklidge. She's a psychologist and the director of the Mental Health and Nutrition Research Group at the University of Canterbury. Her research has focused on the impact of nutrition on brain metabolism, gut microbiome and how our mental health is directly tied to the gut-brain axis. We kōrero with Julia about the findings of her studies and expose the barriers she's faced challenging the status quo, with Scientific institutes unwilling to publish and promote research on the basis that it questions the existing treatments.
