A new study has found that memory loss conditions such as Alzheimer's could be improved by drinking blueberry juice.
Published in the Journal of Agriculture and Food Chemistry, the report from scientists at the University of Cincinnati and the US and Canadian Departments of Agriculture, found that drinking commercially available blueberry juice could reduce memory loss.
The experiment looked at one group of volunteers in their 70s with early memory decline who were given between two and two and a half cups of blueberry juice every day for two months.
A control group were not given the juice.
The juice group showed significant improvement in learning and memory tests.
"These preliminary memory findings are encouraging and suggest that consistent supplementation with blueberries may offer an approach to forestall or mitigate neurodegeneration," the report said.
A spokesman for the Alzheimer's Society in the UK said: "A healthy diet is an important way to reduce your risk of developing dementia. Evidence suggests antioxidants found in fruit, vegetables, tea and even red wine can help prevent oxidation, a process associated with cell damage and ageing."
