Drinking coffee can reduce the risk of heart failure. Correlation between caffeine and reduced risk of heart failure.

A meta-​​ analysis just published in the Journal of the American Heart Association found that drinking one or more cups of caffeinated coffee a day was associated with a significantly lower risk of heart failure.

The analysis covered three major medical studies involving more than 21000 adults, each of which was followed up for 10 years. Drinking at least one drink a day can reduce the risk of heart failure by 5-12%, according to a study. Another showed no change between zero and one cup, but people who drank two or more cups of caffeinated coffee a day reduced their risk by about 30 percent, according to the team of cardiologists behind the new analysis.

"the association between caffeine and reduced risk of heart failure is surprising," David P. Kao, senior author of the study and medical director of the Colorado Personalized Medical Center at the University of Colorado School of Medicine, said in an AHA statement. People generally think that coffee and caffeine are "harmful" to the heart because they are associated with palpitations, high blood pressure and so on. The consistent relationship between increasing caffeine intake and reducing the risk of heart failure makes this hypothesis a reality. "

Unfortunately, the risk reduction seems to be related only to caffeinated coffee, not non-caffeinated coffee, the researchers said. In at least one analytical study, non-caffeinated coffee may increase the risk of heart failure. The group has not recommended drinking coffee as a tool to reduce the risk of heart disease, but instead points to quitting smoking, weight control and exercise.

Heart health news is another major medical victory for coffee. After decades of description, coffee has been described as potentially harmful to health due to misunderstood associations and inadequate research.

A well-established diuretic and potential sleep disruptor that varies from person to person, just in the past two years, coffee in various forms and volumes has also been shown to be a potential potion for improving brain function after sleep deprivation, fighting prostate cancer and improving the colon. Cancer results, improve bone health, prevent type 2 diabetes, improve the outcome of kidney disease, and even resist death itself.

In a recent heart study published in the AHA journal Circulation: heart failure, researchers noted many inherent limitations in analysis, including a lack of standard cup measurements between the three studies explored, a lack of information on coffee preparation methods or additions, and a lack of information on whether caffeine intake through other drinks may affect heart health outcomes.

"although causality cannot be proved, interestingly, these three studies have shown that coffee drinking is associated with a reduced risk of heart failure, and without sugar and high-fat dairy products, drinking coffee can be part of a healthy eating pattern like cream," said Penny M. Kris-Etherton, a cardiologist at Penn State University and a former chairman of the leading committee of the AHA lifestyle and Heart Metabolism Health Committee. Bottom line: as part of an overall heart-healthy diet, enjoy coffee in moderation, in line with recommendations for fruits and vegetables, whole grains, low-fat / skim dairy products, and low sodium, saturated fat and added sugar.
