Olive oil contains vitamin E, which supports the normal function of the immune system as well as maintaining healthy skin and eyes, and is a good source of vitamin K, which is needed for blood clotting and wound healing. It’s the oil’s antioxidant status which provides a lot of its nutritional value, graded using the ORAC (Oxygen Radical Absorbance Capacity) scale. Diet
