Omega-3 fatty acids play a significant role in a balanced diet, contributing to overall health in various ways. These essential fats support heart health by reducing inflammation, lowering blood pressure, and decreasing triglyceride levels. Additionally, omega-3s are vital for brain function and mental well-being, potentially reducing the risk of mental disorders such as depression. They also promote joint and eye health, making them critical for individuals engaged in active lifestyles. Incorporating sources such as fatty fish, flaxseed, and walnuts into the diet can provide adequate omega-3 intake.
