The good news was made possible by researchers who studied 200,000 nurses and doctors for over 30 years. In this study, they concluded that drinking coffee reduces the risk of dying from heart disease and other causes.
The study was done by the Deparment of Nutrition, Harvard School of Public Health, Boston and was released to the public on November 16.
The study was made possible by undergoing physical examinations and complete questionnaires on diet and behavior, including coffee habits. This was done periodically to 74, 890 wmoen in the Nurses' Health Study (NHS), 93,054 women in the NHS 2 and 40,557 men in the Health Professionals Study.
Significant observations were done between coffee consumption and deaths due to cardiovascular disease, neurological disease and suicide. However, observations for total cancer mortality rate were not present in this study.
The study showed that for a non-smoker who drinks a cup of coffee a day, a 6% reduce risk of death from heart disease was found. The same group who drank at least three cups was getting an 8% reduced mortality rate. The ones that drank at least five cups daily, had a 15% reduced risk on mortality and those who drank more than five cups daily had 12%.
The difference between the coffee being decaf or not, had little effect on the study's outcome. The study continues after controlling for alcohol consumption, age factor, B.M.I. and other health and diet factors.
While this proves to be promising, Dr.Ming Ding, of the Harvard School of Public Health said "our study is observational, so it's hard to know if the positive effect is casual or not." Too much of all substances in your body can cause damage, the keys to success is in moderation.
For those people who smoke and drink coffee, the study was not clear, since the causes of mortality from smoking out weighs, that of drinking coffee.
