When heated, olive oil is the most stable fat, which means it stands up well to high frying temperatures. Its high smoke point (410ºF or 210ºC) is well above the ideal temperature for frying food (356ºF or 180ºC). The digestibility of olive oil is not affected when it is heated, even when it is re-used several times for frying. This is regular olive oil. Extra virgin olive oil loses vitamin when heated.
Coconut can be used for frying foods. Set the temperature between 325º and 375º.
The smoke point of coconut oil is relatively high, at 350 degrees Fahrenheit, which is the same as butter. Lard has a smoke point of 370 degrees, while regular olive oil has a smoke point of 420 degrees. Heating an oil above its smoke point can form compounds that can be harmful to your health. Never heat an oil at a temperature that burns an oil or generates smoke from the oil. You can safely use coconut oil in a frying pan to fry eggs, but keep the temperature moderate to prevent exceeding its smoke point.
