Blueberries have been shown to improve memory and learning in old rats. Now a small study indicates that aging humans may get similar benefits. Volunteers in their 70s were chosen because they were experiencing memory slips and other signs of cognitive deterioration. They drank roughly 2.5 cups of blueberry juice daily for three months. A comparable group received a placebo drink for the same period of time. The elderly subjects who drank the blueberry juice performed better on memory tests, word associations and list learning than the people drinking the placebo beverage. Bottom line…blueberries appear to be good for the brain, whether you are a rodent or a human.
