Coffee, Cardiovascular Disease, Stroke Risk and Heart Failure- What Do the Studies Say?

“But drinking moderate amounts of coffee is linked to lower rates of pretty much all cardiovascular disease, contrary to what many might have heard about the dangers of coffee or caffeine…”

I am a long-term cancer survivor, cancer coach and parent of one child. Both my son and I love coffee. Because I firmly believe in the importance of lifestyle therapies and health, I watch out for information about nutrition and health-coffee in this case.


The N.Y. Times article linked and excerpted below cites and links a series of “meta-analyses” aka studies of studies about coffee’s effect on various health issues. I developed chronic atrial fibrillation in late 2010 from the aggressive chemotherapy I underwent in ’95 for my cancer. Heart damage is a known side effect of Adriamycin and Cytoxan– two of the chemotherapy regimens my oncologist prescribed. As a result of my chronic a-fib I focus on my heart health with moderate, frequent exercise, nutrition, supplementation, etc. And coffee…

To be clear I am talking about black coffee. No sugar, no milk, nothing added. According to the article below ” Regular brewed coffee has 5 or fewer calories and no fat or carbohydrates…” Further, my coffee drinking son Alex just topped 6’7” and weighs about 170 lbs. Coffee consumption did not stunt his growth.

The bottom line is that moderate consumption of coffee, defined as drinking 2-6 cups a day, is associated with a lower risk of cardiovascular disease, stroke risk and heart failure.

In addition to my heart-healthy lifestyle discussed above I supplement with both omega 3 fatty acids and green tea extract. I do so mainly because I worry the most about my a-fib and risk of stroke. Research has shown that both of these supplements reduce the risk of stroke.

More Consensus on Coffee’s Effect on Health Than You Might Think

“When I was a kid, my parents refused to let me drink coffee because they believed it would “stunt my growth.” It turns out, of course, that this is a myth. Studies have failed, again and again, to show that coffee or caffeine consumption are related to reduced bone mass or how tall people are

Coffee has long had a reputation as being unhealthy. But in almost every single respect that reputation is backward. The potential health benefits are surprisingly large...

Just last year, a systematic review and meta-analysis of studies looking at long-term consumption of coffee and the risk of cardiovascular disease was published. The researchers found 36 studies involving more than 1,270,000 participants. The combined data showed that those who consumed a moderate amount of coffee, about three to five cups a day, were at the lowest risk for problems. Those who consumed five or more cups a day had no higher risk than those who consumed none…

Years earlier, a meta-analysis — a study of studies, in which data are pooled and analyzed together — was published looking at how coffee consumption might be associated with stroke. Eleven studies were found, including almost 480,000 participants. As with the prior studies, consumption of two to six cups of coffee a day was associated with a lower risk of disease, compared with those who drank none. Another meta-analysis published a year later confirmed these findings…

Rounding out concerns about the effect of coffee on your heart, another meta-analysis examined how drinking coffee might be associated with heart failure. Again, moderate consumption was associated with a lower risk, with the lowest risk among those who consumed four servings a day. Consumption had to get up to about 10 cups a day before any bad associations were seen…

No one is suggesting you drink more coffee for your health. But drinking moderate amounts of coffee is linked to lower rates of pretty much all cardiovascular disease, contrary to what many might have heard about the dangers of coffee or caffeine. Even consumers on the very high end of the spectrum appear to have minimal, if any, ill effects….”
