According to Reuters:
People who regularly drink green tea may have a lesser risk of mental decline as they grow older, researchers have found.
Their study, of more than 1,000 Japanese adults in their 70s and beyond, found that the more green tea men and women drank, the lower their odds of having cognitive impairment.
Apparently the Japanese also have a lower rate of Alzheimer’s and dementia than Europeans and North Americans. [Say what?-ed. Shut up and drink your tea.]
