Salmon contains omega-3 fatty acids — a type of fat that makes your blood less likely to form clots that may cause heart attacks. Omega-3s may also protect against irregular heartbeats that may cause sudden cardiac death, and they help decrease triglyceride levels, decrease the growth of artery-clogging plaques and slightly lower blood pressure.
