Regular fish consumption has been shown to reduce the risk of atrial fibrillation (AF). Researchers from the University of Kuopio (Finland) tested this hypothesis by studying the association between the serum long-chain n-3 PUFAs and risk of AF in men. A total of 2174 men , 42 to 60 years old, were studied. They concluded that an increased concentration of long-chain n-3 PUFAs in serum, a marker of fish or fish oil consumption, may protect against AF.
