The gut-brain axis (GBA) refers to the bi-directional communication that
occurs between the gut and the brain. Recently, studies have highlighted
the important role of nutrition in modulating the GBA. We will delve into this
exciting area of research and understand how certain diets and foods may
be linked to mood and mental health.
Our understanding of the gut-brain axis has
rapidly advanced over the past decade – from
analysing observational data to investigating
physiochemical aspects and nutritional
modulation of the axis. However, there are many
questions researchers are investigating. Which
species and strains of bacteria help with certain
neuropsychological conditions? Which foods
and dietary components can promote the growth
of these ‘psychobiotic’ strains? How effective is a
psychobiotic diet when compared with already
existing clinical approaches?
The authors are excited about the prospect of
research around the gut microbiota connecting
these dots, and helping translate concrete
scientific evidence into practical advice.
