- Two international studies show a link between a longer life and coffee intake
- The studies note that coffee-drinkers tend to have a longer life than non-coffee drinkers
- However, experts raised that results must be interpreted carefully
Two international studies have shown that there is a link with life longevity and coffee intake, despite stirring objections among experts.
A study by the International Agency for Research on Cancer (IARC) and Imperial College London found coffee drinkers who take three cups a day tend to live longer than those who do not.
“We found that higher coffee consumption was associated with a lower risk of death from any cause, and specifically for circulatory diseases, and digestive diseases,” IARC’s Marc Gunter explained in an Agence France Presse story.
The joint study observed more than half a million people in 10 European countries. Researchers say this is the largest examination of coffee-drinking habits in Europe.
Meanwhile, another study by the Keck School of Medicine of the University of Southern California found that coffee drinkers are less likely to suffer from heart disease, cancer, stroke, diabetes and kidney failure.
“Those who drank one cup a day were 12 percent less likely to die compared to those who didn’t drink coffee. Those who drank two or three cups per day saw an even higher 18 percent reduced risk of death,” wrote the AFP story; citing details from the study.
The study involved 180,000 participants in the United States.
Experts, however, reminded that the results must be carefully interpreted.
They noted some loopholes in the study, which include the failure to update the coffee intake. One study took a 16-year period before conclusion.
Some also noted that the study was not able to pin point the cause and effect link between coffee and life longevity.
“If these estimated reductions in all-cause mortality really are causal, then an extra cup of coffee every day would on average extend the life of a man by around three months, and a woman by around a month,” said David Spielgelhalter of the University of Cambridge.
