Omega-3 fatty acids are vital for heart health due to their anti-inflammatory properties and ability to improve lipid profiles. They help reduce triglyceride levels, lower blood pressure, and decrease the risk of arrhythmias. Furthermore, these fatty acids support overall cardiovascular function by promoting healthy blood vessel function and reducing arterial stiffness. Regular consumption of Omega-3-rich foods like fatty fish contributes to long-term heart health and may lower the risk of heart disease, making them essential for a well-rounded diet.
