For years, your morning joe got a bad rap from health experts. But newer research suggests coffee may actually be good for you—if you follow the rules
“I gave up coffee” is a refrain of the health conscious. But should it be? The idea that coffee is a dangerous, addictive stimulant springs mostly from 1970s- and 1980s-era studies that tied the drink to higher rates of cancer and heart disease, explains Dr. Rob van Dam, a disease and nutrition expert at Harvard School of Public Health who has examined coffee and its health effects. According to van Dam, that old research didn’t do a great job of adjusting for a person’s cigarette habit or other unhealthy behaviors.
But newer, better-designed research paints a more benign picture of your favorite eye-opener. Van Dam and his colleagues analyzed health and diet data on roughly 130,000 adults spanning 24 years. They found no evidence that drinking coffee increases your risk of death from cancer, cardiovascular disease, or other causes. That was true even for people who knocked back 48-ounces of coffee a day. In fact, there was some indication that regular coffee drinkers might enjoy a slight drop in mortality risk, van Dam says.
