Corn oil is one of the most popular cooking oils in the world.

It’s cheap, it’s flavorless, and it has a high smoke point, which makes corn oil a go-to choice for high heat frying, and particularly deep frying. Corn oil is also in margarine, salad dressings, beauty products, and more.

Corn oil is a vegetable oil, and like all vegetable oils, it’s high in polyunsaturated fat.
