The document discusses a study on the effects of berry fruit supplementation on the aging brain. The study found that rats fed diets supplemented with extracts from strawberries or spinach showed prevention of age-related declines in motor and cognitive behavior compared to a control group. Specifically, blueberries, cranberries, Concord grape juice and strawberries have been found to be effective in reversing motor deficits. Different fruits may act in different brain regions to produce beneficial effects. Berry fruits like blueberries and strawberries appear to improve cell signaling related to learning and memory. Nutritional interventions containing berry polyphenols may help strengthen the brain against aging and reduce risks of neurodegenerative diseases.
