Blueberry juice for better memory

A new study supports the belief that ingesting blueberries can improve memory. Robert Krikorian of the University of Cincinnati's Department of Psychiatry and his colleague published a paper suggesting that the anthocyanins in the berries may boost neuronal signaling and help get rid of glucose in the brain, both of which would slow the death of brain cells.

In the study, one group of volunteers in their 70s with early memory decline drank the equivalent of 2-2 l/2 cups of a commercially available blueberry juice every day for two months. A control group drank a beverage without blueberry juice. The blueberry juice group showed significant improvement on learning and memory tests, the scientists say. "These preliminary memory findings are encouraging and suggest that consistent supplementation with blueberries may offer an approach to forestall or mitigate neurodegeneration," said the report.
