A 2013 study published in the journal Mayo Clinic Proceedings analyzed how coffee consumption affects people's health, depending on the amount they consume. The researchers observed more than 43,700 generally healthy individuals—meaning they did not have a prior history of heart attack, stroke, or cancer—for an average of 17 years. During the study period, 2,512 deaths occurred. Based on these results, men and women under the age of 55 who drank more than 28 cups of coffee each week had a significantly higher risk of all-cause mortality than those who did not drink coffee, at more than a 50 percent increased risk. You may be able to drink more coffee if you are a woman over the age of 55. According to the study, there were no adverse outcomes with higher coffee consumption for women 55 years and older—but there was for men. The researchers found that men of all ages had a 21 percent increased risk of all-cause mortality when they drank more than 28 cups of coffee each week.
