Fish in Diet May Help Maintain Heart Rhythm 8/1/06
Tuesday, August 01, 2006
Eating tuna or other broiled or baked fish appears to have a beneficial effect on the electrical system of the heart, which may help prevent life-threatening heart rhythm disorders, according to a new report. Previous reports have linked fish intake with a reduced risk of sudden death and irregular heart beats, but the mechanisms responsible for this association were unknown.
However, evidence from animal studies has suggested a direct effect from fish oil intake on the hearts electrical circuitry. As reported in the Journal of the American College of Cardiology, Dr. Dariush Mozaffarian, of Harvard Medical School, Boston, and colleagues analyzed data from 5096 adults enrolled in the Cardiovascular health Study to investigate the link between dietary intake of fish and omega-3 fatty acid and features seen on electrocardiograms.
