We have constantly wrote articles on the benefits of coffee, and like wonders that never cease, here's another round of research that just adds another benefit to it.

Drinking one to two cups a day may lower the risk of heart failure. Researchers looked at a handful of studies of the link between java and heart health and found that moderate coffee consumption has positive effects, despite concerns that caffeine could possibly hurt the heart.

"The American Heart Association published a guideline statement saying that coffee may be harmful and that it may increase the risk of heart failure," said lead author Elizabeth Mostofsky, a research fellow at Beth Israel Deaconess Medical Center in Boston.

"Since then, other studies have been done," she said. "We summarized the literature and found that across the studies, moderate coffee consumption may reduce a person's risk."

The researchers found after analyzing studies from 2001 to 2011 that drinking the equivalent of two 8 ounce cups of coffee may lower heart failure risk as much as 11 percent.

But like anything and everything else, moderation is key.

"Chronic coffee use may actually blunt some of the effects," said Dr. Elizabeth Ross, a cardiologist and spokeswoman for the American Heart Association.

On top of that, there's prior research to suggest that coffee consumption might help lower the risk of Type 2 diabetes, which in turn increases the likelihood of heart failure. A 2009 study in the Archives of Internal Medicine found that with each cup coffee that a person consumed daily, the risk for diabetes dropped 7 percent.

"There is a lot of research showing that coffee has antioxidant benefits. That's the main mechanism that people tend to focus on," said Mostofsky, suggesting a possible link between coffee and the decreased risk for diabetes. "But it requires further research."

And like all things concerning health, eating well and exercising should always be in the mix.
