There are a lot of different stories about olive oil round. Thus, it would be dangerous to be to frying and there is the question whether all that fat should even be good for you.
Time to dive deeply into the matter and to clarify.
What is olive oil?
Olive oil is a vegetable oil obtained by pressing of the seeds (and sometimes the flesh) of the olive. It goes like this works.
To begin the olives picked either manually or mechanically shaken from the trees.
Then they are washed and processed into pulp. Used to be done with the press; Nowadays it is also used a meat grinder.
During pressing, the crushed olives are crushed between two stones. Asked the fruits were still heated, now it is no longer necessary.
Increasingly it is in countries including Spain, France, Italy and Greece use of centrifugation.
This production is more efficient and centrifuged oil generally has a softer and purer taste.
People know olive oil for about 6000 years; around the year 1200 BC the Phoenicians brought the olive tree to Italy.
The trees (Olea Europeae) thrived in the Mediterranean climate and more countries around the Mediterranean applied themselves in the course of time on the production of olive oil.
The oil is used in food preparation, but also has applications for the skin (moisturizing properties). Used to do it also serves as fuel for oil lamps.
Here is an overview of the three types of olive oil.

This usually consists of a mix of 85 percent refined olive oil (stripped of impurities) and 15 percent virgin olive oil. The flavor is neutral and milder than that of virgin and extra virgin varieties.
Ordinary olive oil is not necessarily unhealthy, but is modified during production.
Where the additional vergine- and virgin oil is processed mechanically, often used chemicals in ordinary olive oil to purify the oil.
Traditional or regular olive oil is filtered, cleaned and bleached, so the water is extracted and the taste is more neutral.
There will, however, also lost a lot of good qualities in this process.
The traditional olive oil is particularly suitable for frying, but my personal preference frying goes to coconut oil.
Extra virgin olive oil
Extra virgin olive oil is also known as unrefined, extra virgin, extra virgin or cold pressed. This is the best olive oil you can get.
He is from the first cold pressing or centrifugation. Legally allowed the acidity of extra virgin olive oil should not exceed 0.8 percent.
Extra virgin has not undergone any treatment processes and is an unprocessed olive juice.
The oil is pure taste and essential healthy properties are herein best advantage. The taste of all types of olive oil the most refined; slightly bitter, fruity, sometimes peppery or grassy. The aroma is dependent on the type of olive, the processing and the soil.
