Recent studies have shown that coffee drinkers are at no greater risk of dying of cancer, heart attacks, or strokes than their non-coffee-drinking peers, and they may even be less likely to die of certain conditions.
Nearly 130,000 middle-aged men and women enrolled in the Nurses’ Health Study and the Health Professionals Follow-Up Study. They were asked about their coffee drinking during the 1980′s and filled out questionnaires every 2-3 years. The study didn’t end until 2004.
It was found that those who drank coffee run about the same risk of dying from cancers or heart diseases as non drinkers.
It’s not thought that it’s the caffeine that had any kind of effect one way or the other, but certain compounds in coffee do have antioxidant properties, which can help circulation, and reduce inflammation.
