Omega-6 refers to a type of polyunsaturated fatty acid that is essential for human health. It plays 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, primarily from sources like vegetable oils, nuts, and seeds. One of the most common omega-6 fatty acids is linoleic acid, which is found in many cooking oils, such as corn and soybean oil. While omega-6 is important, it is essential to maintain a balanced intake with omega-3 fatty acids to support overall health and reduce inflammation.
