The fear: Our caffeine addiction will drive us to a heart attack.
The facts: There is very little evidence that a cup of Joe will send you to an early grave; in fact, the opposite may be true. In 2012, the New England Journal of Medicine reported on the health of 400,000 Americans over the course of 13 years. The scientists found that people who drank between three and six cups a day were around 10% less likely to die during the 13-year period, with lower rates of heart disease, stroke, diabetes and infections. Considering a string of studies examining the health of more than a million individuals, a review in 2014 painted a similar picture: people who drank four cups a day were around 16% less likely to die at any one time.
Note that these were only observational studies. Although they tried to account for other factors, there’s no way of knowing if the coffee itself was protecting the heart, or if there’s some other, hidden, explanation. Perhaps healthier people are just more likely to be drawn to coffee. But as “addictions” go, it’s pretty harmless.
In a nutshell? It’s probably not the elixir of life that some claim, but based on this evidence, you can at least savour that morning espresso with impunity.
