Research: More Coffee Leads to Higher Death Risk

Chris Bernard/Getty Images(ROCHESTER, Minn.) -- Americans love their coffee: Sixty-four percent of us are regular coffee drinkers and the average coffee drinker chugs 3.1 cups of java a day.

But new research from the Mayo Clinic shows that men and women under the age of 55 who drink more than four cups of coffee a day had a higher risk of dying -- from any cause -- than their non-coffee-drinking peers.

Researchers looked at more than 43,000 adults from 1971 to 2002, and analyzed their coffee consumption, in addition to dozens of demographic and health factors. They found that people under 55 years old who drank more than four cups of coffee a day had a significantly higher risk of dying than those who didn’t drink coffee -- 56 percent higher for men and 113 percent higher for women.

The exact reasons for the higher mortality in heavy coffee drinkers aren’t clear; it could be related to stress, high caffeine intake, lack of sleep, or other associated factors.
