Lubyomysla is divided into refined andUnrefined. Literally a few hundred years ago, unrefined oil was considered second-rate or a product for the poor, but nowadays everything has changed, it is unrefined, the most healing and useful, and the refined one says that it has no useful properties left. So where is the truth?
The use of various oils depends on the composition,The ratio of acids and fats - it does not change after refining, which means one thing - the benefits of oil should not be measured by refining, because there are completely different degrees of it and you need to be able to understand them.
For what purpose does the oil refined?
It is appropriate for the purpose of refining oil,If the refining does not affect the composition? This is done in order to make the oil neutral, almost tasteless.

If you use unrefined oil forCooking hot dishes, for example, for baking or when frying, then the oil will do more harm than good, after all, smoke, fuel, foam - and it all has an unpleasant taste and smell. If the food is overcooked, unrefined oil can form harmful substances in food, especially if the temperature during cooking is high.

They differ not only in taste. Refined oil, for example, does not smoke and does not apply foam when cooking hot.
Frying in oil
To make the refined oil smoke, it is necessary that the frying pan was caked. The temperature when the oil is smoked is called the smoke point and the specified oil, these points are different.
If we fry something and the oil starts to burnAnd smoke, it contributes to the formation of carcinogens, and this is very harmful.

If a person who cooks food will breatheVapors of acrolein, then vitoge will earn a bunch of chronic diseases, and the quality of the dishes will not be at an altitude. So, when frying, use only refined oil and do not overheat the frying pan.
The second generation of oil smoldering produces otherHarmful compounds. For example, polymeric acids and radicals, which remain on dishes. If you frequent these dishes, you can get chronic health problems, even development of oncology.
Brown on a fried potato, which weJust adore, contains acrylamide. This substance has carcinogenic properties and is capable of destroying DNA. The greatest amount of this harmful substance is formed when deep-fried - such food, for example, is the main dish in McDonald's.
That only does not contain overcooked fish or meat! For example, heterocyclic amines are formed inside the piece, which contribute to the development of cardiac diseases. And in the hot, which burnt, polycyclic carcinogens contain a lot of carbon - it happens when the oil is used not for the first time, and besides, if they cook on a heated frying pan.
Peroxides are carcinogens, they are also formedWhen frying with sunflower oil, which is very common in Central Russia. Therefore, the best way to cook on olive oil, it almost does not form harmful carcinogens. No wonder the Mediterranean diet is the most useful, because it is based on olive oil!
