Go ahead, reach for that second cup of coffee — it's doing you even more good than battling an afternoon slump. A new, large-scale study says that drinking two to three cups of coffee a day may reduce your risk of death from many different complications.
The results, published in Circulation, are based on data from three large studies looking at the habits of over 200,000 people for up to 30 years. Researchers found that moderate coffee drinkers (those who drank fewer than five cups a day) had a lower risk of dying from heart disease, type 2 diabetes, neurological diseases, and suicide. Scientists aren't quite sure yet why coffee seems to be so good for our health, but one theory is that it's because naturally occurring compounds in coffee beans help reduce insulin resistance and inflammation in the body.
More studies are planned to see if theories prove true, but this latest study is just more good news for coffee drinkers. Previous research has found that coffee may also help increase endurance, improve memory, and reduce your risk of many diseases. Even so, too much of a good thing can have a negative effect on your health, so enjoy coffee in moderation and keep your caffeine addiction in check in order to reap the health benefits of the beverage.
