I guess that’s a good thing for coffee drinkers… Woohoo! Coffee won’t kill you!
Joking aside, it is a pretty important finding since previous research on the relationship between caffeine and death has been inconsistent.
What’s more, and what’s getting the news buzz, is that the scientists found a modest benefit to drinking coffee. Women that consumed 2-3 cups of caffeinated coffee a day had a 25% lower risk of heart disease-related death than those that didn’t drink any coffee. Those that drank 4-5 cups a day had a 34% lower risk. This effect was strongest in women- it was found to not be statistically significant in men.
What’s interesting is that those that drank decaffeinated coffee also had slightly lower death rates. As such, the benefit doesn’t seem to be related to the caffeine in coffee but perhaps to another compound.
The researchers caution that the possibility of coffee having a health benefit needs to be further investigated. Scientists also warn that caffeine affects everybody individually and can cause various side effects for certain people, including increased heart rate, heart palpitations, anxiety, insomnia etc. Caffeine has also been linked to an increased risk of miscarriages therefore if you’re a women that can become pregnant, you want to limit your caffeine intake to 300mg a day.
The participants in the study were all healthy so the effect of coffee can be different if you have a chronic illness. Coffee consumption was also self reported by the participants only ever 2-4 years, thus introducing possible measurement errors.
Bottom line: Don't start increasing your coffee intake to try to live longer just yet.
