Japanese Study: Green Tea Protects the Aging Brain
Along with brain exercise and exercise, nutrition plays a vital role in brain effectiveness and Alzheimer's prevention. New research points to green tea as being especially beneficial.
NEW YORK (CogLabs Newswire) - 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.
The findings build on evidence from lab experiments showing that certain compounds in green tea may protect brain cells from the damaging processes that mark conditions like Alzheimer's and Parkinson's disease.
But while those studies were carried out in animals and test tubes, the new research appears to be the first to find a lower risk of mental decline among green-tea drinkers, according to the study authors.
They speculate that the possible protective effects of green tea may help explain Japan's lower rate of dementia, particularly Alzheimer's disease, compared with Europe and North America.
Dr. Shinichi Kuriyama and colleagues at Tohoku University Graduate School of Medicine report the findings in the current issue of the American Journal of Clinical Nutrition...
