If you are getting forgetful as you get older, then a research team from the University of Reading and the Peninsula Medical School in the southwest of England has good news for you. Antioxidant-rich foods, such as blueberries, are effective at reversing age-related deficits in memory. The researchers supplemented a regular diet with blueberries over a 12-week period, and found that improvements in spatial working memory tasks emerged within three weeks and continued throughout the period of the study.
Drinking tea (also high in antioxidants) also improved mental function in another study.
