Drinking Decaffeinated Coffee May Be Harmful To Heart Health

Decaffeinated -- not caffeinated -- coffee may cause an increase in harmful LDL cholesterol by increasing a specific type of blood fat linked to the metabolic syndrome, hints a new study presented at the American Heart Association's Scientific Sessions 2005.
The Coffee and Lipoprotein Metabolism (CALM) study included 187 people, randomized to three groups: one that drank three to six cups of caffeinated coffee a day; another that drank three to six cups of decaffeinated coffee a day; and a third, the control group, that drank no coffee.
Some studies have linked coffee drinking to heart disease, but others have suggested that it is not harmful.
"The problem with the results from these previous studies is that many of them were association studies, which looked broadly at free-living populations and drew associations between lifestyle factors, volitional coffee consumption, and disease risk. Our study randomized subjects to a specific type and amount of coffee consumption, brewed in a standardized manner, just like a drug study," said H. Robert Superko, M.D., lead author of the study and chairman of molecular, genetic, and preventive cardiology at the Fuqua Heart Center and the Piedmont-Mercer Center for Health and Learning in Atlanta, Ga.
