Women do not develop high blood pressure by drinking coffee. A link has been found between cola drinking and hypertension.
A study, published in the Journal of American Medical Association, found "strong evidence to refute speculation that coffee consumption is associated with an increased risk of hypertension in women."
Previous studies have offered conflicting reports about the link between caffeine consumption and hypertension, but experts also say that healthy bodies learn to tolerate a couple of cups of coffee daily.
The study was based on analyses of 12 years of data on 33,077 cases of high blood pressure among 155,594 women participating in the Nurses Health Study, which is jointly run by the hospital and the school. Wolfgang Winkelmayer of Brigham and Women's Hospital and the Harvard School of Public Health conducted the study.
However, a relationship was found between hypertension and consumption of caffeinated colas, independent of whether the soft drinks were sugared or diet. The current study did not look at non-cola soft drinks. "We feel that it is not caffeine but perhaps some other compound contained in soda-type soft drinks that may be responsible for the increased risk in hypertension," the study said.
As many as 50 million people in the United States suffer from hypertension, and the number is rising.
