These molecular changes result in； changes in flavor, as well as W changes in nutritional value，specifically，the nutritional value of the oil starts to reduce；changing what once may have been considered an especially healthy oil，like Olive，into one that is unhealthy． The higher an oil’s smoke point is，the higher the temperature of the oil can be．As a result, each type of oil should be used for the cooking method that is most appropriate to its individual smoke point and heat tolerance.
