Large study shows drinking coffee could extend your life

Large study shows drinking coffee could extend your life

A new study published Monday in Jama Internal Medicine found that drinking large amounts of coffee may help you live longer.

Another large study of 500,000 people in Europe showed similar results to the recent United Kingdom research: men who drank three cups of coffee per day were 12% less likely to die over a 16-year period than coffee abstainers, and women who drank that much coffee were 7% less likely to die.

From a consumer perspective, it's a win-win for coffee drinkers, even for those who may prefer decaf for all or part of the day due to caffeine sensitivity. Dr. Tara Narula, cardiologist at Northwell Health, joins "CBS This Morning" to discuss the findings.

He added: "Healthier coffee, free from sugar or syrup, should also be encouraged to optimize any health benefit".

So the study seems to suggest you can get much the same health benefits from cheap supermarket coffee as from a fancy cup of artisanal terroir coffee.

Edward Giovannucci, a professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health, who was not part of the study, agreed.

The study covered people who drank instant, ground and decaffeinated coffee.

"There are many potential beneficial compounds in coffee - there are literally hundreds and thousands of compounds in coffee", he said.

And some of their habits and characteristics might make these British coffee-drinkers look unhealthier to start with. While the study represents an median view of coffee drinking habits, it is encouraging reading for lovers of the toasted bean. Researchers noticed an inverse association between drinking coffee and the risk of death, regardless of whether individuals metabolized it quickly or slowly. But overall, "coffee drinkers were about 10 percent to 15 percent less likely to die than abstainers during a decade of follow-up", according to an Associated Press report on the study.

"There has been concern about the health effects of heavy coffee drinking, particularly in participants with common genetic polymorphisms that affect caffeine metabolism", the researchers wrote.

But coffee drinkers in the study didn't have higher risks than non-drinkers of dying from heart disease and other blood pressure-related causes.

The FDA has suggested that Americans consume no more than 400mg of caffeine, or four cups of coffee, per day.

Previous research has shown similar results.

And she notes that it's a rare treat when there's something that feels good and actually is good for us. "Or at least not be bad", Lichtenstein said. The results suggested that people who drank two to five cups of coffee in a day were about 12% less likely to die than non-coffee-drinkers over the 10-year time period in the study.
