Washington, July 23: Based on a study by 'Annals of Internal Medicine' drinking coffee can make you live longer. In the study spanning 16 years, researchers observed that regular and decaffeinated coffee drinkers experience health benefits like increased life span and low risk of cancers and chronic diseases.
The research, published in the journal the Annals of Internal Medicine, suggests an extra cup of coffee could lengthen a person's lifespan even if it is decaffeinated. Around 1,85,000 people from African Americans, Japanese Americans, Latinos to Whites were examined.
Researchers from the International Agency for Research on Cancer and Imperial College London say they have found that drinking more coffee is linked to a lower risk of death - particularly for heart diseases and diseases of the gut.
Prof Sir David Spiegelhalter, from the University of Cambridge, analyses the public understanding of risk and says that if the estimated reductions in death really were down to coffee, then an extra cup of coffee every day would extend the life of a man by around three months and a woman by around a month on average.
But despite the sheer scale of the study, it is by no means perfect and cannot prove that coffee beans are the magic ingredient. Previous studies have shown conflicting and often contradictory results.
For many people, experience suggests that drinks containing caffeine can temporarily make us feel more alert. But caffeine affects some people more than others, and the effects can vary from person to person.
