Another new study shows that green tea may protect an aging brain. Green tea is very popular in Asia and has long been deemed as a soothing health tonic. Japan has a lower rate of Alzheimer’s disease and other forms of dementia than the U.S. and other Western countries, and it could be attributed to the high levels of green tea consumption.
Researchers from The American Journal of Clinical Nutrition found that seniors in Japan who drank one or more cups of green tea a day were half as likely to show cognitive and memory problems as those who drank less. The more tea the subjects drank, the lower their chances of having mental difficulties. Members of green tea-drinking cultures usually consume three cups a day.
Green tea contains the potent compound EGCG, which seems to inhibit the production of beta-amyloid, a toxic protein that clogs the brains of Alzheimer’s victims. Other studies show that EGCG may prevent heart disease, certain cancers, bacterial infections and the spread of HIV.
