Sunflower oil is the undefeated champ of vegetable oil, as it’s the healthiest oil among them. Made from pressing the seeds of the sunflower plant, the oil composes of different fatty acid levels. You can buy sunflower oil containing 82% oleic acid (high oleic) or 65% oleic acid (mid-oleic). The varying amounts of oleic acid give you the option to choose sunflower oil with either high oleic acid or mid oleic acid. Your body uses oleic acid as fuel and helps strengthen cells and tissues. Sunflower oil receives its award for being the healthiest vegetable oil because it’s free of protein, cholesterol, sodium, and carbohydrates. Since sunflower oils are rich in oleic acid, they contain high levels of monounsaturated fat and low amounts of polyunsaturated fat.
