Can Coffee Really Protect the Heart?

Coffee has long been touted as a healthy drink that have an effect. However, many people still hesitate to drink it black. A recent study attempted to answer these doubts. They expressed a moderate amount of coffee per day may protect against heart failure.

“We found that moderate amounts of coffee consumption in fact be protective,” said Elizabeth Mostofsky, the leader of the study and researcher at the Harvard School of Public Health in Boston. The study was published on 26 June 2012 in the journal Circulation failure.

“There are many factors that can contribute to the risk of heart failure, but moderate amounts of coffee consumption is not one of them,” he added.

Heart failure is a condition where the heart of the difficulty pumping enough blood throughout the body. Penyebanya could be due to hypertension or coronary heart disease. According to data from the National Institutes of Health, approximately five million people in the United States have heart failure and the disease accounts for 300,000 deaths per year.

The researchers concluded that about 8-caffeine coffee per day (equivalent to four servings of coffee in the Northern Europeans) heart failure may occur, increasing the risk of the disease to 11 percent.

Instead, drink too much coffee – more than four or five cups of coffee per day – can actually reduce the risk of heart problems.

In kajiaannya, researchers reviewed five studies of coffee consumption and risk of heart failure associated published between 2001 and 2011. The study included 140 220 volunteers in Sweden and Finland. Nearly 6522 volunteers including heart failure.

This study did not distinguish between caffeinated and decaffeinated coffee, caffeinated coffee, but tend to be the second choice in the Nordic countries.

Several previous studies have shown that coffee consumption may protect against several diseases, including type 2 diabetes, Parkinson’s disease, liver cancer and cirrhosis of the liver, it may even improve performance during exercise.

While health experts still warn that pregnant women consume no coffee, because they tend to have problems in controlling blood pressure, blood sugar, or heart palpitations (irregular heartbeats) to have.

Investigators said he did not fully understand how coffee has a protective effect against cardiovascular disease has. Mostofsky said, people who regularly drink coffee usually a tolerance for caffeine in coffee, which means they tend not to feel the effects to develop. It can make them at a reduced risk of high blood pressure. In addition, the antioxidants in the coffee cells, assumed to be damaged.

Yet not all medical experts agree with the results of the study. “The evidence is not strong enough to recommend that people drink coffee to protect themselves,” said Dr. Arthur Klatsky of the Kaiser Permanente Medical Center in Oakland, California, who was not involved in this study.

Klatsky, who has done research on the relationship between heart rate and coffee, said coffee drinking is a lifestyle factor. “Maybe people who drink coffee tend to exercise more and have better diets,” he said.

But, he said, “People should not feel the need to avoid coffee as they risk failure to feel.”
