Good news for coffee
January 24, 2013
PEOPLE who drink caffeinated
coffee have a lower risk of some
oral cancers, according to a new
American Cancer Society study.
Published in the American Journal
of Epidemiology, the study
examined associations of
caffeinated coffee, decaffeinated
coffee, and tea intake with fatal
oral/pharyngeal cancer in the
Cancer Prevention Study II, a
prospective US cohort study begun
in 1982 by the American Cancer
Society.
The research involved 968,432
men and women who were cancer
free at the start of the study, and
noted 868 deaths due to oral/
pharyngeal cancer occurred during
26 years of follow-up.
The researchers found consuming
more than four cups of caffeinated
coffee per day was associated with
a 49% lower risk of oral/pharyngeal
cancer death relative to no/
occasional coffee intake).
A dose-related decline in relative
risk was observed with each single
cup per day consumed, and
interestingly the association was
independent of sex, smoking
status, or alcohol use.
In addition, the study noted a
similar link among those who drank
more than two cups of
decaffeinated coffee per day,
although, according to researchers,
that finding was only marginally
significant.
No association was found for tea
drinking.
“Coffee is one of the most widely
consumed beverages in the world,
and contains a variety of
antioxidants, polyphenols, and
other biologically active
compounds that may help to
protect against development or
progression of cancers,” said the
study’s lead author Janet
Hildebrand, MPH.
