- A new study shows that people who drink coffee, even those who drink eight or more cups a day, are less likely to die early than non-coffee drinkers.
- The study, published in the journal JAMA Internal Medicine, found that even people who metabolize caffeine slowly are less likely to die early if they drink more coffee.
- This adds to a significant body of research indicating that coffee is connected to a long list of health benefits.
Feel free to pour yourself a cup of coffee before reading this – even if you’ve already had some today.
Yet another study has found that drinking coffee is associated with a longer life and lower risk of an early death. This adds to a significant body of research indicating that coffee has positive effects on the heart, liver, brain, and more.
The latest study, published in the journal JAMA Internal Medicine, reveals that people who drink more coffee have a lower risk of death even if they drink eight or more cups per day, and even if their genetics make them slow to process caffeine.
The study looked at 500,000 people in the UK, of whom 387,494 were coffee drinkers. 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. People who drank six to seven cups were 16% less likely to die, and people who drank eight or more cups were about 14% less likely to die.
It didn’t matter whether the coffee was decaf or regular, ground or instant – all were beneficial (though the connection to lower risk of death was weaker for instant coffee).
Up to eight cups a day – or more
This recent study drew from data from the UK Biobank study, an in-depth research initiative collecting data and following 500,000 people for three decades. The group studied was 54% female and had an average age of 57. Ten years after the start of the study, 14,225 people had died. Among at least the generally healthy individuals from the UK enrolled in this study, coffee drinkers seem to gain health benefits from the habit. The study results showed coffee drinkers had a lower risk of death overall, just as many other studies have found.
Because some people’s genetics make them slower to metabolize caffeine, the researchers wanted to see if that made coffee consumption riskier for these individuals. But it turns out that even slow caffeine metabolizers seem to share the death-risk-reduction connected to coffee drinking.
