Coffee has been one of the most studied dietary substances and yet the research remains inconsistent. A number of studies have linked it to potential health risks, including anxiety, cardiovascular disease, and even cancer while others support a host of possible health benefits—from protecting against diabetes to preventing liver and heart disease. There is even evidence that drinking coffee can help you live longer: One study from 2015 found that the consumption of coffee (both caffeinated and decaffeinated) was associated with a lower mortality rate.
Researchers at the University of Colorado looked at the Framingham Heart Study, a long-running project that was started in the ‘40s to help identify risk factors of heart disease. For their analysis, the researchers used a technique known as machine learning, which is essentially a super-smart algorithm designed to detect data patterns. They found that for subjects who consumed coffee, every eight-ounce cup per day reduced these risks by 7 percent, 8 percent, and 5 percent, respectively, compared to those who didn’t.
The researchers then corroborated the results using traditional analysis in two studies with similar sets of data. “The association between drinking coffee and a decreased risk of heart failure and stroke was consistently noted in all three studies,” reads a statement from the AHA. While these findings have yet to be published in a peer-reviewed journal, this is further proof that a brew (or two) is good for you.
