Caffeinated coffee may have an
undeserved bad rap. A new study shows the decaffeinated variety may have harmful
heart effects. The study showed that people who drank decaf had higher levels of
a protein linked to heart disease risk compared with those who drank caffeinated
coffee or no coffee. "But the differences were fairly small and there’s probably
no health threat from drinking a cup or two of any type of coffee a day," says
researcher H. Robert Superko, MD. The research is the latest entry into a long
line of scientific studies looking at whether coffee drinking can lead to heart
disease. The participants were given premeasured bags of coffee
to make in their coffee machines provided by researchers, They agreed to drink
it black--no cream or sugar al-lowed. And they agreed to periodic blood tests so
the researchers could k A. caffeinated coffee is healthier than decaffeinated coffee B. caffeinated coffee can bring benefit for those fat people C. decaffeinated coffee is more likely to deserve such a charge D. decaffeinated variety can also cause harm to people’s health
