In which type of food would you typically find linoleic acid?

Olive oil
Corn oil
Butter
Palm oil

The correct answer is: Corn oil

Linoleic acid is an essential fatty acid that belongs to the omega-6 family. It is commonly found in various vegetable oils, particularly those that are derived from seeds. Corn oil is a prime source of linoleic acid, as it is extracted from the germ of corn and has a high concentration of polyunsaturated fatty acids. This oil is often used in cooking and food production due to its favorable health profile compared to saturated fats. In contrast, olive oil is rich in monounsaturated fats, particularly oleic acid, while butter contains saturated fats and palm oil is primarily comprised of saturated and medium-chain fatty acids, making corn oil the best choice for sources of linoleic acid.
