CHICAGO (AP) -- A small study suggests that eating dark chocolate can lower
your blood pressure - a delicious instance in which something that tastes good
might, for a change, be good for you, too.
The short study would need to be confirmed in larger, longer-term ones before
doctors could recommend treatment with chocolate, researchers say.
Yet if the results can be confirmed, "you can sin with perhaps a little less
bad feeling," said Dr. Franz Messerli, a hypertension expert at Ochsner Clinic
Foundation in New Orleans.
The German study appears in Wednesday's Journal of the American Medical
Association.
Thirteen adults with untreated mild hypertension got to eat 3-ounce chocolate
bars every day for two weeks. Half of the patients got white chocolate, half
got dark chocolate.
Dark chocolate contains plant substances called polyphenols - ingredients
scientists think are responsible for the heart-healthy attributes of red wine.
Polyphenols also have been shown to lower blood pressure in animals.
Blood pressure remained pretty much unchanged in the group that ate white
chocolate, which does not contain polyphenols. But after two weeks, systolic
blood pressure - the top number - had dropped an average of five points in the
dark-chocolate group. The lower, or diastolic, reading fell an average of almost
two points.
The participants had an average blood pressure reading of about 153 over 84.
While their blood pressure did not fall enough to be considered in the
desirable range - below 120 over 80 - the results show dark chocolate "might serve
as a promising approach to reduce systolic blood pressure," said lead author
Dr. Dirk Taubert of the University of Cologne.
Taubert said participants ate the chocolate bars instead of the sweets they
usually consumed, and thus did not gain weight during the study.
The study received no industry funding - the researchers bought the chocolate
themselves from the supermarket.
