Essential fatty acids (EFAs) that should be included in the diet are omega-3 and omega-6 fatty acids. Omega-3s, found in fatty fish, flaxseeds, and walnuts, are crucial for heart health, brain function, and anti-inflammatory processes. In contrast, omega-6 fatty acids, primarily found in vegetable oils and nuts, play a role in cell membrane structure and overall metabolic health. A proper balance between omega-3 and omega-6 fatty acids is essential for maintaining optimal health. Regularly incorporating sources of both EFAs enhances overall well-being and reduces the risk of chronic diseases.
