There’s now one more reason to get your morning fuel from coffee: it’s good for your heart, according to new research.
The study, published in an American Heart Association journal, comes from the Cardiovascular Epidemiology Research Unit at Beth Israel Deaconess Medical. Based on their findings, researchers now believe drinking two cups of coffee a day will lower the risk for diabetes, which as a result lowers the risk for heart failure.
The size of your ‘two cups of coffee’ is important, however, and shouldn’t exceed more than 8 ounces. By keeping these parameters, researchers say people may be able to lower their risk of heart failure by as much as 11 percent compared to non-coffee drinkers. But if you exceed that 16-ounce a day limit, it may actually undermine the beneficial qualities.
The first author of the study, Elizabeth Mostofsky, explained this is because “protection slowly decreases with more consumption and it seems there’s no further benefit for people who drink five or more servings a day and there may actually be potential for harm.”
The 10-year study analyzed five separate studies that took place between 2001 and 2011, which included at a total of 140,220 patients. The studies took place Finland and Sweden where caffeinated coffee is typically consumed, although there may have been some decaffeinated mixed in among the group. While researchers focused on the amount of coffee participants drank each day, they did not take into account how the coffee was brewed, how strong it was, or what time of day it was consumed.
This new research may be in correlation with a previous study from the New England Journal of Medicine that touted two cups of coffee a day was linked to a longer life. In any case, it seems a cup of joe isn’t just a vice or source of energy for people anymore, it’s actually a weapon against some serious health risks. And that’s reason enough for me to gladly keep up my two-cup-a-day habit.
