       Drinking coffee to halt cognitive decline?

       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.

       Can caffeine protect against cognitive decline?
       Bonnie Liebman
       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.
       “In mice that are bred to get Alzheimer’s, caffeine can reduce
       or reverse the amyloid burden,” says Kang.
       Another possibility: “Caffeine seems to be protective for
       depression, which also increases the risk of dementia.”
