Coffee has been linked to a lower risk of Parkinson’s, which is
a neurological disease that can cause tremors, balance
problems, and mobility issues. In one 2000 study in the
the American Medical Association, researchers looked at 30
years of data from over 8,000 Japanese-American men in Hawaii.
They found that the more daily coffee they drank (up to 28
ounces, or 3 to 4 cups), the lower their risk of Parkinson’s
compared with those who drank little or none. (The same seemed
to be true of caffeine-containing beverages in general, so the
theory is that the caffeine may be responsible.) There is so
much research on this that the amount of evidence for the link
is “substantial,” according to a 2017 review, but
still “not conclusive,” so do with that what you will.
