Caffeine’s reputation continues on the upswing. New research from the University of Washington, in Seattle, finds that moderate consumption of caffeine, previously exonerated of raising cholesterol levels, has now been found innocent of contributing to fatal disruptions of heart rhythm.
Researchers looked at 362 cases of cardiac arrest, in which the heart suddenly stops beating, often with no apparent history of heart disease. Through interviews with surviving spouses, the researchers estimated the caffeine intakes for the deceased during the prior year.
They found no increased risk for those who drank the caffeine equivalent of less than five cups of coffee a day, compared to those who consumed the caffeine equivalent of less than one cup. Consuming five or more cups a day, however, did increase risk.
