How Does Your Heart React to Coffee?
Submitted by Ann On 2007-09-13
A 2005 study found that íIn contrast to early studies, recent research
indicates that habitual moderate coffee intake does not represent a health
hazard and may even be associated with beneficial effects on
cardiovascular health íIn fact, no clear association between coffee
and the risk of
heart attack or other cardiovascular diseases has been demonstrated
Data collected for the first National Health and Nutrition Examination Survey Epidemiological (NHANES I) by James Greenberg and colleagues at the City and State Universities of New York (American Journal of Clinical Nutrition, 2007, 85 (2): 392- 398), revealed that those over 65 with normal blood pressure who drank at least 4 caffeinated beverages a day had a 53% reduced risk of death from cardiovascular disease.
Caffeine may escalate the risk of heart attacks in some coffee drinkers, but lower the risk in others, based on the presence of genes that govern whether the body processes the stimulant slowly or quickly, scientists report today. Heart attacks might be a risk for coffee drinkers with a common genetic trait that makes caffeine linger in their bodies, a study suggests.
Correspondingly, hyper cholesterolaemic people younger than 59 with the rapid *1A genotype lowered their risk of heart attack by 52% when drinking 1 cup of coffee daily; 2-3 cups a day lowered risk by 43%, and 4 or more cups daily resulted in a reduction in heart attack risk of 17%.
In plain language that means that for those who process coffee fast, coffee reduces the risk of heart attacks. However, for the slow ones it increases the risk of heart attacks as much as heavy smoking.
Persons with or at increased risk of developing high cholesterol levels should drink only filtered coffee. Epidemiological studies have linked consumption of boiled, but not filtered, coffee with increased risk for cardiovascular disease (CVD).
Research has shown that caffeine consumption may have a small effect on blood pressure; however, scientists do not consider coffee drinking to be an important risk factor for hypertension.
risk factors are known to be a low potassium intake, high sodium
intake, sedentary lifestyle and
