Fish consumption and risk of stroke in men

Men who eat fish at least once a month can lower their risk of a stroke by 40%, according to a 12-year study of 43,671 men. Eating fish more frequently did not substantially lower the risk any more than 50%. Most strokes are caused by a blood clot in the brain that cuts off the blood supply to various parts of the brain. Fish consumption did not reduce the risk of a hemorrhagic stroke, which is caused by bleeding inside the brain.
