“…A growing body of literature supports a protective role of fish intake and of essential dietary long-chain polyunsaturated fatty acids in cardiovascular disease (Dolecek & Granditis, 1991;Ascherio et al, 1995;Daviglus et al, 1997;Hopper et al, 1999;Oomen et al, 2000;Rissanen et al, 2000;Hallgren et al, 2001;Iso et al, 2001;Yuan et al, 2001) including a reduction of the risk of sudden cardiac death (Siscovick et al, 1995;Albert et al, 1998). There are several potential mechanisms for this protection including antithrombotic (Kristensen et al, 1989;Prisco et al, 1995) and anti-arrhythmic effects (Marchioli et al, 2002), decreased heart rate variability (Christensen et al, 1997) and resting blood pressure (Knapp, 1989), decreased serum LDL cholesterol and triglyceride concentrations (Agren et al, 1996) and increased insulin sensitivity (Torjesen et al, 1997;Mori et al, 1999).…”
