       From Nutrition Action, January 17, 2014, comes the news that
       caffeine might protect the brain against cognitive decline. A
       person would need to drink 4-5 cups of coffee a day, however,
       and the results are only preliminary.

       > Caffeine may protect your brain. “In our study of people who
       already had an increased risk of cognitive decline because of
       cardiovascular risk factors, consuming about 500 milligrams of
       caffeine a day was strongly associated with memory
       preservation,” says Jae Hee Kang, assistant professor of
       medicine at Harvard Medical School and the Brigham and Women’s
       Hospital in Boston.

       > “It seems to require high levels of caffeine—four or five cups
       of coffee a day.” (That’s if it’s Maxwell House or Folgers. At
       Starbucks, you get 415 mg of caffeine in one venti and 520 mg in
       two tall coffees.)
       >
       > The study found no lower risk among people who drank decaf or
       cola or tea, possibly because they got less caffeine.

       > Until a trial tests caffeine against a placebo, though, it’s
       not clear that it protects the brain. Even so, researchers have
       some reason to expect that caffeine may help.

       or reverse the amyloid burden,” says Kang.

       > Another possibility: “Caffeine seems to be protective for
       depression, which also increases the risk of dementia.”
