What is a primary dietary source of linoleic acid?

Linoleic acid is an essential omega-6 fatty acid that plays a crucial role in various bodily functions, including inflammation regulation and cell membrane structure. Among the available options, sunflower oil is recognized as a primary dietary source of linoleic acid.

Sunflower oil typically contains a high concentration of polyunsaturated fats, particularly linoleic acid, making it an excellent dietary source. In contrast, while pine nuts, olive oil, and avocado do contain some beneficial fatty acids, they are not as rich in linoleic acid compared to sunflower oil. Pine nuts primarily provide monounsaturated fats and some omega-3 fatty acids, olive oil is largely known for its high content of monounsaturated fats (especially oleic acid), and avocado is also rich in monounsaturated fats. Thus, sunflower oil stands out as the most significant source among the given options for obtaining linoleic acid in the diet.
