Three Cups Coffee per Day ForExtend Age?

This is good news for you who like to drink coffee. One study indicates that adults who consume three or more cups of coffee a day tend to live longer. In fact, the risk of dying from the most common causes decreased by 10 percent than those who drank no coffee. This is a large-scale research conducted by experts from the U.S. National Cancer Institute, which involved nearly 400,000 people. This finding applies to those aged 50-71 years both drinkers of caffeinated coffee or decaffeinated. Research shows that coffee drinking was associated with a decreased risk of death from heart disease, respiratory disease, stroke, diabetes, infections, and injuries and accidents. However, researchers stress, contribute to improving the health of coffee consumption remains unclear. These findings do not establish causality. "I think these findings are really important to point out that our study is an observational study. That is, we only ask how much they drank coffee and then watching them," said lead researcher Neal Freedman, of the U.S. National Cancer Institute in Rockville, Md.. Freedman revealed that coffee drinkers tend to smoke more generally - is the leading cause of death. "We found that coffee drinkers tend to face a higher risk of death. But when we do not connect it with cigarettes, we found an inverse relationship." he said. The study was published on May 17, 2012 in the New England Journal of Medicine. For this study, the researchers focused on the eating habits of 400,000 men and women involved in the National Institutes of Health-AARP Diet and Health Study between 1995 and 1996. None of the participants had a history of cancer, stroke or heart disease. Each participant was asked about their coffee consumption, ranging from zero to six cups a day or more. The health condition of participants tracked since 2008 or until death. The results showed that drinking even one cup of coffee a day was associated a lower risk of death. But uniquely, drinking coffee is not associated with a decreased risk of cancer death in women, and only have a protective effect in men only. The protective effect appeared greater among those who drank more than one cup a day. Even so, Freedman noted, few benefits were seen in those who drank two cups a day and six cups a day. "Going forward, we need to really look at the different components in coffee. In addition to caffeine, coffee contains about 1,000 other compounds and antioxidants, some of which may be beneficial and some not," said Freedman. Freedman added, and the way of presenting a good selection of coffee types also need to be explored further. "We do not know if this also affects the progression of the disease," he explained. Freedman recommends, everyone should consult a doctor before starting to drink more coffee. The reason, personal health history can affect how much the amount of coffee consumption are allowed to receive.

Can Coffee Really Protect the Heart?

Coffee has long been touted as a healthful beverage which 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 every day can protect against heart failure. "We found that moderate amounts of coffee consumption in fact be protective," said Elizabeth Mostofsky, leader of the study and researcher at the Harvard School of Public Health in Boston. The study was published on June 26, 2012 in the Journal Circulation Heart 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 artery 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 annually. The researchers concluded that about 8-ounces of caffeinated coffee per day (equivalent to four servings of coffee in the northern Europeans) can prevent heart failure, reducing the risk of the disease up to 11 percent. Instead drink too much coffee - more than four or five cups of coffee a day - can actually increase the risk of heart problems. In kajiaannya, researchers reviewed five studies of coffee consumption and risk of associated heart failure published between 2001 and 2011. The study involved 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 northern European 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 not consume coffee because they tend to have difficulty in controlling blood pressure, blood sugar, or palpitations (irregular heartbeats). Investigators said he did not fully understand how coffee has a protective effect against heart disease. Mostofsky said, people who regularly drink coffee usually develop a tolerance to caffeine of coffee, which means they tend not to feel its effects. It may put them at a reduced risk of high blood pressure. In addition, the antioxidants in coffee are believed to protect cells from damage. Even so, not all medical experts agree with the results of the study. "The evidence is not strong enough to recommend that people should 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 conducted research regarding the relationship between heart rhythm and coffee, said coffee drinking is a lifestyle factor. "Maybe people who drink coffee tend to exercise more or have better diets," he said. However, he said, "people should not feel the need to avoid coffee if they are at risk for heart failure."
