According to one study, people who consume more foods high in antioxidant flavonols, which are present in many fruits and vegetables, as well as tea and wine, may experience slower memory decline. The findings are published in the online edition of Neurology, the medical journal of the American Academy of Neurology. Flavonols are a type of flavonoids, a group of phytochemicals found in plant pigments known for their beneficial health effects. The study involved 961 people with an average age of 81 without dementia. They were also asked about other factors, such as their level of education, how much time they spent in physical activities, and how much time they spent in mentally appealing activities such as reading and playing games. They were followed for an average of seven years.
