Two cups of coffee reduce heart failure risk

Reading time: 2 minutes
two cups of coffee a day

Drinking two cups of coffee every day can reduce your chances of heart failure by as much as 30 percent, but it’s the caffeine in the drink that is producing the healthy benefits. Decaffeinated coffee could even increase the risk.

The tipping point seems to be at two cups. Drinking even one cup a day didn’t protect the heart, say researchers who took another look at three studies.

The results were surprising, say researchers at the University of Colorado School of Medicine, especially as coffee is usually thought to be bad for the heart. “People associate coffee with palpitations and high blood pressure, but these findings turn the assumption on its head,” said researcher David Kao.

The three studies had recruited a total of more than 21,000 participants, whose coffee drinking was measured, from zero cups to more than three cups a day, and their health was tracked for 10 years.

One study found the risk of heart failure fell by up to 12 percent for every cup of coffee, and another discovered the risk fell by as much as 30 percent in those who drank two cups a day.

Decaffeinated coffee didn’t have any protective effect, and even increased the risk in one study. This suggests that it’s the caffeine that protects the heart, and so any caffeinated drinks, such as tea, could also be reducing the risk of heart failure.

But drinking coffee still isn’t the best way to protect against heart disease. Stop smoking, lose weight and exercising are still better strategies, the researchers say.

And it’s important the coffee you drink doesn’t have added sugars or cream. The simpler the coffee, the better it will be for your heart.
