Common Types of Oils
High in mono- and polyunsaturated fats and antioxidants, nutty-tasting sesame oil comes in two basic forms. Light oil, pressed from untoasted seeds, has no strong aroma, so goes well with many dishes. Dark toasted-sesame oil, used in Asian and Indian dishes, has a more concentrated flavor and more antioxidants and vitamin E; it is used for flavoring, as a condiment, or in stir-fries (sprinkled over them at the end of cooking), not for frying.
So maybe you can’t change your health overnight. But you can get a head start.
