Look, coffee is a health drink.
Study after study after study after study after . . . has clearly shown that (with a very few exceptions like perhaps early in pregnancy) compared to people who don’t drink coffee, people who do drink coffee have better health outcomes – no matter what you decide to measure, especially, I must point out, a chance to live longer.
So, yes, there’s a very very very small chance that perhaps there’s a genetic (or other) difference between coffee drinkers and those who decide to avoid coffee (well, we coffee drinkers are both prettier and smarter and wittier), and perhaps it’s those differences and not the coffee intake that leads to better health outcomes, but that’s a really mightily small chance.
Anyway, despite repeated studies showing that coffee drinkers do not have higher risks of strokes, heart attacks, cardiac arrhythmias, sudden death due to cardiac problems, many doctors and cardiologists still warn their patients off drinking coffee because, well, because everyone knows that coffee causes heart problems.
No, it doesn’t.
And the newest study to wave a wand over coffee intake looked at 300000 health records in the U.K. Biobank whose average age was 57 (old guys like you and me).
Over 13000 people developed a cardiac arrhythmia over the next 5 years – pretty par for the course in such a group – and of those, 4700 developed atrial fibrillation.
Conclusion: coffee drinkers were actually less likely to develop any abnormal heart rhythm than were the coffee-abstainers, even those who claimed to drink 5 cups of coffee a day.
In other words, coffee is a health drink.
