Tea drinking associated with lower cognitive impairment and decline risks - study!

A recent study made in Singapore has concluded that regular consumption and intake of tea was associated with lower risks for cognitive impairment and cognitive decline.
"Laboratory research suggests that tea has potential neurocognitive protective effects, but this is not established in humans," writes Tze-Pin Ng, from the University of Singapore , and colleagues. |
The study's aim was to find out whether there is indeed a relationship between tea consumption and cognitive impairment and decline among community-living Chinese adults 55 years or older in the Singapore Longitudinal Ageing Studies cohort. For so long, tea has always been associated with various health benefits and many studies performed in the past tended to suggest correlation, possibly even causation, between the two.
Independent of other risk factors, total tea intake was significantly associated with a lower prevalence of cognitive impairment.
For cognitive decline, black (fermented) and oolong (semi-fermented) teas were associated with the most prominent effects. There appeared no apparent association between coffee intake and cognitive status.
"Regular tea consumption was associated with lower risks of cognitive impairment and decline," the study authors write.
"The potential effect of tea drinking in protecting against the cognitive decline of advanced age thus has great significance, given the rapid aging of the population and the rising prevalence of vascular and Alzheimer-type dementia," the study authors conclude.
