All the oils have a certain smoke point. Smoke point is the point at which, when an oil is exposed to higher temperatures, the fats in the oil tend to break down and get degraded, i.e., they lose their quality. The higher is the smoking point, the safer are the oils even, when exposed to high temperatures. So, what we have to do is, whenever a deep fried food is there in the menu, choose the oil with a higher smoking point.

Most of the oils used for deep frying are hydrogenated or partially hydrogenated vegetable oils which are rich in trans fat and this trans fat in long run may cause an increase in your cholesterol levels. Trans fat is usually an adulterated form of fat which helps in increasing the longevity of the processed foods but decreases the longevity of our lives.
But due to the recent advances in chemistry and medicine many are aware of the dangerous effects of long term use of hydrogenated vegetable oils and have shifted towards Olive oil, Rice bran oil, Safflower oil, Sunflower oil and Corn oil. These oils may be healthy, but, when exposed to higher temperatures constantly, they USUALLY turn out be UNHEALTHY.
The oils which are loaded with Saturated and Monounsaturated fats, like, Olive oil, Coconut oil, Ghee, Avocado oil, Peanut oil, Sunflower oil and Rice bran oil are known to have a higher smoking point and tend to be safer for deep frying.

The oils with polyunsaturated fats, such as, Safflower oil, Corn oil, Canola oil and Soybean oil are unsafe for deep frying as they break down easily at higher temperatures and form FREE RADICALS. These free radicals, are the main culprits of all the Metabolic diseases occurring nowadays and also the cause of increased Incidence of Cancer.
Over all, research studies have shown that Coconut oil is safer for deep frying and do not break down that easily. Next is the Olive oil and Avocado oils which are preferable. Peanut oil is also safe and even the Sunflower oil or Rice bran oil is safe, whereas the Safflower oil is dangerous.
Choice is yours, CHOOSE WISELY TO STAY HEALTY LONGER .
