New research from the US suggests drinking coffee in moderation, that is four European cups (equivalent to two 8-ounce American servings) per day, may protect slightly against heart failure, contradicting the guidelines of the American Heart Association that currently warn against regular coffee consumption.
You can read a paper on the study, by researchers at Beth Israel Deaconess Medical Center (BIDMC) and Harvard School of Public Health in Boston, in the 26 June issue of the journal Circulation Heart Failure.
Some previous studies have suggested there is a protective heart benefit from regular coffee consumption, while others have found no such link. So in this new study, the researchers decided to look at the data differently, and shift the debate from a question of "yes" or "no" to "how much".
