Coffee drinkers around the world are in luck, as a recent study suggests that coffee (decaf included) may be good for your health. Though studies have shown both health benefits and drawbacks, this study, which suggests that coffee drinkers may have a reduced risk of death, takes another element into account.
U.S. participants in the study were asked not only how much coffee they consumed, but were also asked questions regarding their consumption of other foods and drinks. Rates of death and disease for the next two decades were then examined.
The study included more than 200,000 women and 50,000 men.
Initially, no evidence of a relationship between coffee and death rate was forthcoming. The study seemed unclear, proving only that those who drank less than half a cup to three cups of coffee a day demonstrated 5-9% lower risk of death than those who did not drink coffee at all, and those that drank more than three cups of coffee did not benefit.
When researchers examined results among only those who never smoked, the findings were much more promising. Among nonsmokers, participants drinking between half a cup and three cups of coffee per day demonstrated 6-8% lower risk of death, and participants drinking three to five cups of coffee each day yielded 12% and 15% lower death risk.
The lower risk of death is believed to be a result of coffee consumption’s link to lower risk for certain diseases, such as type 2 diabetes and heart disease.
Those involved in the study believe that benefits from drinking coffee could have been obscured by smoking in previous studies as the two tend to go hand-in-hand.
