If you suffer from Cardiovascular Disease (CVD or coronary heart disease) and/or fear you might some day due to high blood pressure, is your coffee consumption compounding
problem? Or, are there other things you can do to alleviate your high blood pressure and CVD concerns that do NOT include ending, or severely lessening, your coffee intake? This article explores reliable answers to those questions. Can Coffee Contribute to Coronary Heart Disease? CVD is
number one cause of death in America and high blood pressure is one of its biggest red flags. CVD has been
subject of extensive medical and scientific research for several decades. While researchers have differed in their conclusions over time, new evidence reported in The American Journal of Epidemiology in 1999 strongly indicates that consumption of coffee and caffeine does not contribute to CVD, finding neither caffeinated nor decaffeinated coffee associated with
risk of stroke—even for those drinking more than four cups of coffee a day.
Warren G. Thompson, M.D., noted in a 1994 literature review published in The American Journal of Medical Sciences, that: "The largest and better studies suggest that coffee is not a major risk factor for coronary disease."
Willet et. al, in a prospective study reported in
February 1996 issue of
Journal of
American Medical Association (JAMA), examined data collected from more than 85,000 women over a 10-year period. After adjusting for known risk factors,
authors found no evidence for any positive association between coffee consumption and risk of CVD for women consuming six or more cups of coffee a day.
A 1990 New England Journal of Medicine study of more than 45,000 men found no link between coffee, caffeine and CVD for those drinking four or more cups of coffee a day.
These results confirm findings from
earlier Framingham Heart Study of more than 6,000 adults conducted over 20 years (as published in
Archives of Internal Medicine) and two 1987 studies using data from
Honolulu Heart Program (published in The New England Journal of Medicine and The American Journal of Epidemiology respectively).
Does Coffee/Caffeine Consumption Contribute to High Blood Pressure? Despite previous controversy on
subject, most researchers now conclude that regular coffee and caffeine use has little or no effect on blood pressure.
Studies reviewed in
Progress in Cardiovascular Diseases indicate that while first-time caffeine use may produce immediate, minimal changes in blood pressure, these changes are transient. No changes in blood pressure appear to occur in regular users of caffeine. A 1991 study published in
British Medical Journal reached
same conclusion and indicated that restricting caffeine did not reduce blood pressure in people with mild hypertension. A number of studies that have looked at people with normal blood pressure (published in
Archives of Internal Medicine and
American Journal of Nutrition) have concluded that caffeine does not contribute to hypertension.
In 1997,
Sixth Report of
National Institutes of Health's Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure concluded that, "no direct relationship between caffeine intake and elevated blood pressure has been found in most epidemiologic surveys."
