"What these chocolate 'offenders' taught us is that the chemical in
cocoa beans has a biochemical
effect similar to Aspirin (ASA) in reducing platelet clumping, which
can be fatal if a clot forms
and blocks a blood vessel, causing a heart attack," lead author
Diane Becker of Johns Hopkins
University School of Medicine said in a statement.
Eating a little bit of chocolate or having a drink of hot cocoa as part
of a regular diet is
probably good for personal health, so long as people don't eat too much
of it - and too much of the
kind with lots of butter and sugar," Dr. Becker said.
