Reports in the Annals of Internal Medicine by medical researchers suggest that drinking coffee may help you live longer. While previous medical research has suggested a link between drinking coffee and a reduced risk for heart disease, diabetes, and Alzheimer’s disease, these reports show that people who drink moderate amounts of coffee appeared to live longer.
In the United States, 50% of adults drink coffee daily. Coffee is a major source of caffeine, and the amount of caffeine can vary greatly depending on the type of drink.
Amount of Caffeine
Instant coffee 8 mg/oz
Brewed coffee 12 mg/oz
Expresso 64 mg/oz
One study reviewed 185,000 patients for 16 years, comparing those drinking no coffee to moderate coffee consumers. They found that drinking one cup of coffee a day was associated with a 12% decrease in risk of death. People who drank 2-3 cups a day had an 18% reduce risk of death.
This trend was similar between caffeinated and non- caffeinated coffee, so factors in coffee other than caffeine appear to play a role.
A second study reviewed longevity in over a half million people in 10 European countries for 16 years. They also found coffee consumption to be linked with a lower risk of death from all causes.
It appears from these studies that higher coffee consumption is associated with a lower risk of death and that moderate coffee intake can be a part of a healthy diet.
