Coffee Drinkers May Live Longer
Your morning cup of coffee may start to taste even better after a major government study found that frequent coffee drinkers have a lower risk of dying from a variety of diseases, compared with people who drink little or no coffee.
The report, published online in The New England Journal of Medicine on Wednesday, analyzed the coffee-drinking habits of more than 400,000 men and women ages 50 to 71, making it the largest-ever study of the relationship between coffee consumption and health.
Previous studies have offered conflicting results on the relative benefits or harms associated with regular coffee consumption. While coffee contains caffeine, a stimulant that may temporarily increase heart rate and blood pressure in some people, coffee also contains hundreds of unique compounds and antioxidants that may confer health benefits. Further confusing much of the research into coffee is the fact that many coffee drinkers are also smokers, and it has been difficult to untangle the relative health effects of coffee and cigarettes.
To learn more, researchers from the National Institutes of Health analyzed diet and health information collected from questionnaires filled out by 229,119 men and 173,141 women who were members of the American Association of Retired Persons (AARP) between 1995 and 1996. The respondents were followed until 2008, by which point 52,000 had died.
As expected, the researchers found that the regular coffee drinkers in the group were also more likely to be smokers. They ate more red meat and fewer fruits and vegetables, exercised less and drank more alcohol – all behaviors associated with poor health.
