Coffee consumption and overall and cause-specific mortality: the Norwegian Women and Cancer Study (NOWAC).

ABSTRACT: Coffee consumption has previously been reported to reduce overall and cause-specific mortality. We aimed to further investigate this association by coffee brewing methods and in a population with heavy coffee consumers.
