Good news for all of you who are already tipping back your second — or third — cup of coffee of the day: you can keep on doing what you're doing.
A new, large-scale, long-term study adds to the growing body of evidence that coffee consumption is, in fact, good for you.
And the study published Monday in the American Heart Association journal Circulation shows that your daily cups of joe may help boost longevity.
This finding is definitely something to take seriously since the study's scale is so massive: the findings are based on data from three ongoing studies, including of a total of over 200,000 participants who answered food questionnaires every four years. During the follow-up period, more than 31,000 participants died of various causes. (Researchers controlled for factors such as smoking, body mass index, physical activity, alcohol consumption, and other dietary factors.)
What they found is that "moderate" coffee drinkers — those who consume three to five cups a day — experienced a lower risk of deaths from cardiovascular disease, neurological diseases, Type 2 diabetes, and suicide.
You might be thinking, Well, maybe that's because coffee drinkers tend to have healthier habits. But, strangely enough, they found that people who frequently drink coffee are much more likely to smoke and drink alcohol.
Of course, however, there is such thing as too much coffee. As we've written before, how much coffee your body can tolerate without getting the jitters may depend on your genetic makeup. So, introverts and anxiety-prone people: be careful with the espressos. Insomnia is not fun.
It's important to note that this study, though massive, does not prove causation between drinking coffee and living longer; rather, it points to a correlation. But if you enjoy waking up to a fresh pot of coffee every morning, it's fine — and likely pretty healthy — to include a few cups of it in your daily routine.
