Coffee. Java. Cuppa Joe. The smell and taste of fresh-brewed coffee is the way many of us start our mornings and power through the day. But because there’s been credible research to suggest that coffee may be related to heart disease in some way, many doctors have recommended restrictions on the amount and type of coffee that people drink. That recommendation may not have been necessary in light of a recently published paper in the April 2006 issue of the journal Circulation.
Researchers from the Harvard Medical School and the Harvard School of Public Health reported that drinking six cups of coffee per day and more did not appear to increase the risk of heart disease. The researchers used data collected from more than 44,000 men since 1986 and more than 84,000 women since 1980; the data included daily coffee consumption, serum cholesterol, and rates of heart disease. They found no association between coffee consumption and heart disease.
One important thing to note is that the researchers specifically used the term “filtered coffee” in their discussion. Unfiltered coffee or boiled coffee may release other chemicals that could be harmful, although that possibility wasn’t tested in this cross-sectional study.
But that doesn’t mean you can drink whatever quantity of coffee you want to drink.
Actually That depends. If your doctor told you to switch to decaffeinated coffee and avoid products with caffeine, you should follow that advice. Caffeine is a stimulant that can cause both heart rate and blood pressure to increase, which may be the reason your doctor wants you to avoid it. But for most of us–for now–there doesn’t seem to be any reason not to enjoy a second cup.
