Tea Protects Your Aging Brain
Drinking as little as one to three cups of tea a day could be
beneficial in staving off mental decline, according to new research
from the University of California.
Experts analysed several studies on the effects of caffeinated
drinks on memory and mental alertness. Those who took part logged
how often they drank tea or coffee and did a memory test used in the
initial stages of diagnosing Alzheimer's disease.
Ten years later, all re-sat the test and any fall in score was
noted. The brain stayed sharper in those who drank tea, the journal
Advances in Nutrition reports.
It is thought compounds in tea may protect against the poisons
that ravage the brain in Alzheimer's. Possibilities include
theanine, a plant chemical found only in tea and in mushrooms.
