Scientists from the University of Wollongong, the University of Queensland, and Victoria University are investigating the Queen Garnet plum, bred in Queensland, for its potential to delay or prevent dementia. The research is focused on the plum's juice and its ability to protect brain function.
Michael Mathai from Victoria University highlights early-stage findings, stating, "There is evidence that people with early-stage dementia or perhaps mild cognitive impairment … can be helped by this." Initial studies indicate that plum extract may reduce inflammation markers. Lab tests show that the extract enhances the formation of new neuronal connections, potentially aiding memory formation.
Yasmina Sultanbawa in Brisbane notes the plum's high anthocyanin content, compounds recognized for their antioxidant and anti-inflammatory properties, which may contribute to improved brain health. Her research explores the gut-brain axis, emphasizing the role of anthocyanins in supporting cognitive function through gut microbiota interactions. "The magic happens in the colon where the poo is," Professor Sultanbawa stated, highlighting the conversion of anthocyanins into beneficial molecules.
The Queen Garnet plum's potential extends beyond dementia, as researchers are also examining its ability to repair traumatic brain injuries. Mathai mentions, "We've already shown the extract will protect against chemically induced damage from oxidative stress, for example, that's a neuro protection area, but … will it help to repair already damaged tissue? That's something which we need to investigate further."
Interest in the Queen Garnet plum has grown, with actor Chris Hemsworth expressing curiosity about its brain health benefits. Hemsworth, who is exploring dementia prevention, has engaged with Nutrafruit, the company marketing the plum, for his upcoming YouTube series. Sid Ghosh, CEO of Nutrafruit, remarked, "It is early conversations; I think they weren't expecting to find something in their own backyard, so there's a lot of energy around that."
As dementia and brain injuries continue to impact society, further research into the Queen Garnet plum's health benefits could potentially influence future healthcare strategies.
