Drinking tea is linked to a dramatic reduction in the risk of cognitive impairment in older people, new research suggests.
A single daily cup of tea reduces cognitive decline in those over 55 by 50%, the Chinese study found.
Among those with a genetic susceptibility to Alzheimer's, though, this risk reduction increased to 86%.
It did not matter which type of tea people consumed: green, black or oolong.
The only thing that mattered was that the tea was brewed from tea leaves.
