Blueberries good for brain - Study

Ten thousand New Zealanders suffer from Parkinson’s disease, and it’s estimated than 1% of all Kiwis over the age of 60 have the condition. Parkinson’s is a progressive, degenerative disorder of the central nervous system, caused by the death of dopamine-generating cells in the brain. Shaking and slow movements are an early symptom of Parkinson’s, which is incurable.
Now, a new study shows that consuming blueberries may actually reduce the risk of contracting Parkinson’s.
Dr Mary Ann Lila, Director of the Plants For Human Health Institute and one of the scientists who conducted the study, says it reinforces how eating certain fruits can have a positive and long-lasting influence on health.
"Historical anecdotal evidence has suggested that consumption of berries may help to reduce the risk of brain-related degenerative diseases," explains Dr Lila. "This study showed that, in the mid-brain, berries rich in two specific classes of phytochemicals - anthocyanins and proanthocyanidins - were particularly effective against the neurodegeneration experienced in Parkinson’s."
Most fruits contain predominantly one phytochemical or the other. Blueberries, however, are uniquely rich in both of these protective groups of natural chemicals.
"Because blueberries have both of these natural chemicals in high concentrations, they pack a more powerful, one-two punch. They can have synergistic benefits that surpass many other fruits when it comes to protection against brain cell death, which in turn may reduce the risk of contracting Parkinson’s."
The study was conducted by a team of scientists from leading US universities and headed up by neurobiologist Dr Chris Rochet. It will be published later this year in Brain Research.
The study’s findings further cement the blueberry’s reputation as "brain food". Previous research has shown that eating several servings of blueberries each week can increase powers of concentration and slow cognitive degeneration.
