Essential fatty acids (EFAs) are critical fats that the body cannot synthesize and must be obtained through diet. The two primary types of EFAs are omega-3 and omega-6 fatty acids, crucial for overall health. Omega-3s are abundant in foods like fatty fish, flaxseeds, and walnuts, while omega-6s are found in vegetable oils, nuts, and seeds. These fatty acids are vital for cellular function, brain health, and inflammation regulation. Adequate intake of EFAs contributes to a balanced diet and can help prevent chronic diseases, promoting overall well-being.
