Coffee Has No Impact on Coronary Heart Disease Risk
Even those who drink six or more cups a day do not raise their chances of heart disease
MONDAY, April 24 (HealthDay News) -- Coffee-drinking has no significant impact on the risk of coronary heart disease (CHD), according to a study published in the May 2 issue of Circulation: Journal of the American Heart Association.
Esther Lopez-Garcia, Dr.P.H., of Harvard School of Public Health in Boston, and colleagues conducted a prospective cohort study of 44,005 men and 84,488 women with no history of cardiovascular disease or cancer. They assessed coffee consumption starting in 1986 for men and 1980 for women, and then every two to four years until 2000.
During the course of the study, there were 2,173 cases of coronary heart disease among men, of which 724 were fatal. There were 2,254 cases among women, of which 693 cases were fatal. When results were analyzed according to quantity of coffee consumption, there were no significant effects after adjusting for age, smoking and other CHD risk factors, even at consumption of six or more cups a day.
"In this large prospective study, we did not find a detrimental effect of coffee consumption on risk of CHD in either men or women. No association was observed for total caffeine intake, decaffeinated coffee, or tea. These results provide strong evidence against the hypothesis that coffee consumption increases the risk of CHD," the authors conclude.
