Linoleic acid is an essential fatty acid that belongs to the omega-6 family. It is crucial for human health because the body cannot produce it on its own, so it must be obtained through diet. Common sources of linoleic acid include vegetable oils, nuts, and seeds. This fatty acid plays a vital role in various bodily functions, including cell structure and function, as well as the production of hormones. Adequate intake of linoleic acid is important for maintaining skin health and supporting overall metabolic processes.
