Omega-6 fatty acids are a type of polyunsaturated fat that are essential for human health. They play a crucial role in brain function, growth, and development. The body cannot produce omega-6 fatty acids on its own, so they must be obtained through diet. Common sources include vegetable oils, nuts, seeds, and certain meats. These fatty acids are important for maintaining healthy skin, regulating metabolism, and supporting reproductive health. However, it's essential to balance omega-6 intake with omega-3 fatty acids, as an excess of omega-6 can lead to inflammation and other health issues. A balanced diet helps ensure optimal health and well-being.
