Consumption of black and caffeinated coffee is beneficial to health, CNN reported.

A review of dietary data from three major studies using analytic tools from the American Heart Association, showed drinking one or more cups of plain, leaded coffee a day was associated with a long-term reduced risk of heart failure.

The analysis showed that compared with non-coffee drinkers the risk of heart failure over time in coffee drinkers declined between 5% and 12% for each cup of coffee consumed daily.

Decaffeinated coffee consumption did not offer the benefit, the study found. Rather the analysis revealed an association between decaf coffee and an increased risk for heart failure.

Heart failure occurred when a weakened heart failed to supply enough blood for the body’s cells to obtain the oxygen required for proper functioning of the body. People with heart failure suffered fatigue and shortness of breath and had trouble walking, climbing stairs or other daily activities.

Penny Kris-Etherton, registered dietitian and immediate past chairperson of the American Heart Association’s Lifestyle and Cardiometabolic Health Council Leadership Committee said in a statement, that while unable to prove causality, it was intriguing that these three studies suggested that drinking coffee was associated with a decreased risk of heart failure and that could be part of a healthy dietary pattern if consumed plain, without added sugar and high fat dairy products such as cream. She was not part of the research.

The study which analyzed self-reported dietary information from the original Framingham Heart Study was published in the AHA journal Circulation: Heart Failure, on Tuesday. The Framingham Heart Study began in 1948, was conducted on 5,000 people with no diagnosed heart disease who lived in Framingham, Massachusetts. In the study the people and their offspring were followed for 72 years over three generations.

In the new study state-of-the-art analytic tools from the AHA’s Precision Medicine Platform were used to compare the Framingham data to the Atherosclerosis Risk in Communities Study and the Cardiovascular Health Study.  The former is a longitudinal, multisite, biracial study while the later is a 10-year-long study of cardiovascular risk in adults over 65.

Taken together the studies provided dietary information on more than 21,000 adult Americans.

The analysis revealed that compared with people who did not drink coffee, the risk of heart failure over time declined between 5% and 12% for each cup of coffee consumed each day in the Framingham Heart and the Cardiovascular Health studies.

The risk of heart failure did not change for drinking coffee or one cup per day in the Atherosclerosis Risk in Communities Study. However, with two or more cups of black coffee consumption a day the risk fell by about 30%, according to the analysis by Powdersvillepost.

Senior author Dr David Kao, medical director of the Colorado Center for Personalized Medicine at the University School of Medicine in Aurora said the association between caffeine and heart failure risk reduction was surprising, in a statement.

He added coffee and caffeine were often considered by the general population to be ‘bad’ for the heart because people associated them with palpitations, high blood pressure, etc. He said, the consistent relationship between increased coffee consumption and decreased heart failure risk turned that assumption on its head.

It may be noted however, that all these studies considered black coffee consumption. However, many people added dairy, flavors, sugars, or nondairy creamers that were high in calories, added sugar and fat, that likely negated any heart-healthy benefits, warns the AHA.

It may also be pointed out that in most studies a cup off coffee was only 8 ounces as against the standard “grande” cup at the coffee shop was double at 16 ounces.
