Drinking Coffee Linked to Longer Life... Again!
In a recent study conducted with over 2,00,000 people, researchers revealed that drinking coffee, decaf or regular, can result in lowered risk of mortality. The research suggested that by drinking 3-5 cups a day improved the survival rates significantly and lowered the risk of premature death by 15%, compared to those who abstained from coffee altogether. Even though the study only reveals a correlation, it is followed after decades of studies that list the general health benefits of drinking coffee. The lead author, Frank Hu from Harvard T.H. Chan School of Public Health, said that "results from this and previous studies indicate that coffee consumption can be incorporated into a healthy lifestyle." For the purpose of study, Hu and his colleagues studied the health records of over 200,000 people obtained from three large clinical trials that include nurses, doctors, as well as other health professionals, as reported by Newswire.
During the research, the participants were given the food questionnaires and were followed up for a period of 30 years. During this period, 30,000 participants died. After combining this collective data, the researchers found that by drinking as many as 5 cups of coffee a day reduced the risk of mortality between 5% and 9% compared to drinking no coffee at all. However, Epidemiologist, Hannah Gardener from the University of Miami told Ars Technica that the people who drink a lot of coffee are also smokers that could have impacted the previous research results.
Hu and his colleagues took out the smokers from their analysis and found that the mortality risks reduced for the moderate and heavy coffee drinkers. "Drinking high amounts of coffee may, in fact, not be bad and may possibly be beneficial for health similar to the consumption of moderate amounts of coffee," Gardener said, reports Fortune.
