New research has revealed that eating grapes and blueberries together can have an overwhelmingly positive impact on your brain.

Experts say that eating polyphenol-rich fruits and vegetables like grapes and blueberries can help forestall age-related physical declines. This was confirmed last month in a study carried out by an international team of researchers from Bordeaux and Quebec.

This group of researchers performed numerous randomized, double-blind, placebo-controlled trials that tested memory, spatial recognition, and learning on four separate groups of both young and old mice. Half of the mice in each of the groups were given a diet rich in polyphenol extracts from grapes and blueberries, while the other half consumed a regular diet.

The researchers concluded that the beneficial effects of a polyphenol-rich extract from grapes were aided significantly by pairing it with a polyphenol-rich extract from blueberries. They found that the aged mice fed the polyphenol-rich diet spent a lot more time examining objects they had never seen before, while ignoring those they had. These mice could also remember where the exit was in their swimming pool despite the start point changing each swim session, and lived a longer sharper life in general during the trials.

An astonishing 52% of the mice who were fed the normal diet died before a single mouse had died from the control-diet group. When the study ended, the mice were found with much higher levels of polyphenols in their blood plasma and brains.

“Although the exact mechanism is difficult to pinpoint, our data provides evidence of both direct and indirect effects on the brain. The well-being of aged people is closely linked to good memory performance and proper brain functioning, which very often deteriorate during aging,” the researchers stated. “Together, the data obtained in this study are in line with the hypothesis that optimized preventive nutrition may promote the maintenance of a satisfactory cognitive state in elderly subjects and may thus prevent or delay dementia, and contribute to healthy aging.”
