Abstract:
Literature review suggests that polyphenols in particular fl avonoids, are benefi cial for mental health during aging
process. This review examines the effect of consumption of all polyphenols groups on mental health and cognitive status
during aging process. The keywords searched were “mental health,” “depression,” “anxiety,” “stress” and “cognitive”
combined with “dietary,” and “polyphenols.” The databases including PubMed, Web of Science and CAB Abstracts were
searched for a period of 10 years. A total of 11 studies were identifi ed to fulfi ll the inclusion criteria. From this review,
polyphenols may confer benefi cial effects towards mental health, in particular the decline in cognitive functions during
aging process, however, some studies showed contradictory results. Polyphenols have been proven to improve language
and verbal ability, which is among the main vulnerable aspects in cognitive decline in pathological brain aging. In
contrast, polyphenols intake did not seem to affect executive functioning. The effects of polyphenols towards cognitive
status were more prominent among the elderly as compared to young and middle-aged adults. This review also shows that
fl avonoids is the main type of polyphenols that confer positive effects towards cognitive status during aging. This review
provides evidence that consumption of polyphenols may lead to cognitive and mental health benefi ts. Further clinical
trials involving human subjects are required with carefully designed methodology to elucidate the potential mechanisms
underlying the relationship between polyphenols consumption and improvement in cognitive and mental health status
