"We found that people who drank two to three cups per day had about a 12 per cent lower risk of death compared to non-coffee drinkers," said Erikka Loftfield, a researcher at the National Cancer Institute.
This population-based study, which includes people aged 38 to 73, draws an association between coffee and health.
