Taking three cups of coffee a day can increase life years

Drinking coffee can add years to your life. It is what it claims an investigation by the National Cancer Institute, in the United States, published by the Daily Mail. The study, conducted with around 500 thousand people showed that the risk of death for older people decreases with coffee consumption. Excess caffeine generally considered unhealthy, but the survey found that coffee can help reduce deaths from heart and respiratory disease, stroke, injuries, accidents, diabetes, and even infections.
According to the medical Neal Freedman, one of the investigators involved in the study, drinking two to three cups of coffee a day reduces the risk of premature death from 10% to 15%. However, alert the physician that higher doses, especially over six cups no longer bring benefits.
Study participants had ages between 50 to 71 years and were followed for 12 years. The biggest obstacle encountered for longevity by helping coffee within the group, according to the doctor, was the link with the cigarette. "In our study, people who drank coffee were more likely to smoke, which is a very strong risk factor for death," said Neal Freedman.
According to the researcher, coffee consumption is also combined with other behaviours linked to health problems such as drinking too much alcohol, too much red meat and maintaining a sedentary lifestyle. "All of these risk factors are usually associated with increased risk of death, which was part of our research as well," he added.
The study did not found as coffee reduces mortality rate, so ordered group research to identify new chemicals that caffeine can contribute to this effect. "Coffee can have this effect by altering blood pressure, but it is possible that other compounds are also important for increased longevity," he explained.
The study, published in Journal of Caffeine Research, also did not clarify if the regular coffee is more beneficial to health than the decaffeinated version.
