There is evidence that a healthy diet can reduce people's risk of Alzheimer's disease and new research suggests that drinking purple grape juice can reduce, or even reverse, memory loss. In a small-scale trial researchers from the University of Cincinnati compared people drinking purple grape juice to those drinking a placebo. The study lasted 12 weeks and both groups' memories were regularly tested. The memories of the group drinking grape juice improved over the course of the study - possibly due to the antioxidants in the grape juice. The participants in the trial were aged between 75 and 80 and already suffering from early memory loss.
