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. While omega-6 is important, it is essential to maintain a balanced ratio with omega-3 fatty acids. An excessive intake of omega-6, often found in processed foods, can lead to inflammation and other health issues. Therefore, a balanced diet is key to ensuring optimal health.
