Decaffeinated Coffee May Pose Heart Risks
Decaffeinated coffee may raise the risk of cardiovascular disease more than regular coffee according to Atlanta investigators at the American Heart Association's Scientific Sessions 2005.
Dr. H. Robert Superko, and colleagues at the Fuqua Heart Center and the Piedmont-Mercer Center for Health and Learning, analyzed the effects of caffeinated and decaffeinated coffee consumption on cardiovascular risk factors in 187 subjects enrolled in a clinical trial known as the Coffee and Lipoprotein Metabolism Study.
The subjects were randomly assigned to one of three groups: non-coffee drinkers, coffee drinkers and decaf drinkers, who drank three to six cups a day for two months.
At the end of the study, Superko found: no significant differences in fasting glucose or insulin (measures used to diagnosis diabetes), total cholesterol, HDL2 (the very good cholesterol) or triglycerides among the three groups.
However, decaf coffee significantly increased free fatty acid levels, which in turn led to an increase in apolipoprotein B, which is associated with LDL cholesterol- the so-called “bad cholesterol”.
