Sunflower oil is not all the same. Traditional high-linoleic varieties are rich in fragile Omega-6 fats, while high-oleic varieties are more stable. Cold-pressed, high-oleic sunflower oil retains more natural nutrients and resists oxidation better than refined versions. Although it is one of the better seed oils, naturally stable fats like olive oil, avocado oil, butter, ghee, and tallow remain the preferred choice.
