Research reveals coffee drinkers live longer.
American Heart Association conducted a coffee study of 200,000 medical doctors and nurses over a period of 30 years.
The study found nonsmoking coffee drinkers, regardless of caffeinated or noncaffeinated, lowers mortality rate.
One cup of coffee a day had a 6 percent reduced risk of death.
One to three cups an 8 percent reduced risk.
Three to five cups a 15 percent reduced risk.
Five cups a 12 percent reduced risk.
Coffee consumption reduces risks of death from heart disease, strokes and suicide, but has no effect on cancer.
The research found smokers who drink coffee do not benefit from the positive effects because of smoking related issues.
