It is still confusing whether coffee consumption is good for health or should be stopped to serve health with some benefits. Coffee and its consumption has become a conflicting subject even among experts because guidelines suggest hazardous effects whereas some are proposing protective benefits.

Reports submitted currently by American Heart Association heart failure prevention guidelines are warning people to stop their habitual coffee consumption whereas there are some other studies that are proposing the positive sides of same.

The recent attachment to the debate has come from Beth Israel Deaconess Medical Center, which this time rather than conflicting upon the severity or benefits of consuming coffee have questioned how much is these drink benefiting or troubling.

"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 lead author Elizabeth Mostofsky, MPH, ScD, a post-doctoral fellow in the cardiovascular epidemiological unit at BIDMC.

In their study, the researchers compared the coffee drinking habits with no consumption at all of the drink. They found that the moderate coffee drinkers are showing 11 percent lower risk of heart failure than the other drinkers.

Authors have highlighted about a statistically significant J-shaped relationship that they studied between habitual coffee consumption and heart failure, which says consumption is beneficial at moderate levels.
