Coffee in Moderation Might Reduce Heart Failure Risk

According to a new study published in the journal Circulation Heart Failure, the researchers found that moderate coffee consumption might reduce heart failure risk.

Although current guidelines of American Heart Association warn patients about the risks associated with coffee consumption, various studies have analyzed the health benefits of coffee. In the new study, researchers at Beth Israel Deaconess Medical Center and Harvard School of Public Health analyzed the relationship between coffee consumption and risk of heart failure by addressing the question - How much to drink?

“Our results did show a possible benefit, but like with so many other things we consume, it really depends on how much coffee you drink,” said Elizabeth Mostofsky, the lead researcher of the study. What is moderate coffee consumption? It’s two 8-ounce cups of coffee per day, or equivalent of four European cups.

The team analyzed data from five previous studies, which included data from 140,220 participants with a total of 6,522 heart failure events. Researchers identified a significant J-shaped relationship between coffee consumption and heart failure. Compared with those who didn't drink coffee at all, participants who drank two 8-ounce cups of coffee per day were 11% less likely to experience a heart failure event. However, as coffee consumption increased, the health benefit decreased. The maximum benefits was at two 8-ounce cups per day. Participants experienced no health benefit when they drank more than five 8-ounce cups per day. In fact, excess consumption of five cups or more per day might have negative health effects.
