Minds Sharp, Study Shows  Feb. 17, 2006 -- Elders who drink
green tea regularly may have sharper minds than those who don't
drink green tea.  The finding comes from a Japanese study
published in The American Journal of Clinical Nutrition.  The
study included about 1,000 Japanese people aged 70 and older.
Participants took tests of mental status including memory,
orientation, ability to follow commands, and attention. They
also told the researchers how often they drank beverages
including green tea.  Those who reported drinking the most green
tea were least likely to show cognitive impairment, based on
their test scores, write Shinichi Kuriyama, MD, PhD, and
colleagues.  Kuriyama works in the department of public health
and forensic medicine at Tohoku University's medical school in
Sendai, Japan.  How Much Green Tea Does It Take?  Drinking at
least two daily cups of green tea was tied to the lowest risk of
cognitive impairment in Kuriyama's study.
