How to choose the best cooking oil (out of 25 kinds)
What you need to know
Smoke point
A smoke point is a temperature at which oil stops simmering and starts smoking thus breaking down. When oil breaks down, it can start releasing chemicals into the food that can give it a bitter flavour, undesirable burnt and harmful substances to the body. Knowing the smoke point of each oil can help you prevent this harmful process.

However, sometimes smoking oil is not bad. For instance, when stir-frying in a heated pan, it can be inevitable. But even then, it shows that your oil is breaking down.
325 degrees F is relatively low and 520 degrees F is the highest.
