Take a trip to the Gut Barrier Reef
Two experts from seemingly unrelated fields – marine biology and medicine – have released a new research report which shows the surprising similarities between the ecosystems of the human gut and the Great Barrier Reef. Leading marine biologist from the College of Science and Engineering at James Cook University Townsville, Associate Professor David Bourne, has developed the pioneering report, which was commissioned by Kellogg’s Australia, in consultation with medical expert Dr Ginni Mansberg.
As it turns out, our bodies have a lot more in common with coral reefs than we might have thought. Both the gut and coral reefs are home to a staggering diversity of life that includes thousands of species of living organisms. A rise in the dominance of one or more of these species can upset the natural balance in either ecosystem.
“There are thousands of species of fish, corals and bacteria living on the Great Barrier Reef and, similarly, it’s estimated we have over 1000 types of bacteria living in our gut,” explains Associate Professor Bourne. “Both are a complex collection of organisms that function together, each with its own purpose. When one species dominates the space, it can create imbalance and affect the overall health of the ecosystem.”
The two ecosystems are so similar, some people aren’t able to tell the difference between them. When presented with images of their gut – like the one at the top of this page – 26 percent of surveyed Australians thought it was an image of a coral reef. As many Australians don’t know that their gut is a living ecosystem, Kellogg’s has used this coral reef analogy and the report to create a world-first virtual reality experience – the Gut Bacteria Reef.
“For overall gut health, we need to look after the species of bacteria that look after us,” Dr Mansberg says. “You don’t need pills and potions. Eating a healthy diet rich in fibre is where you should start. A high-fibre diet includes a variety of fruits, vegetables, fibre-rich cereals and whole grains, nuts, seeds and legumes. Probiotics like yoghurt are also beneficial, but you won’t be realising the full potential of probiotics without prebiotics like fibre.”
According to a recent study in the journal Nutrients, two out of three Australian adults aren’t meeting their daily fibre requirements of 25-30g. But by showing Australians the invisible world inside their bodies and how fibre feeds “good” gut bacteria, it’s hoped this will build a better understanding of the link between a healthy diet and good gut health.
