Ever since people started looking for healthy cooking options, olive oil has become a part of their monthly grocery list. But do we know all about this supposedly healthy cooking option?
Olives are amongst the oldest foods known to mankind and today even their oil is gaining popularity, despite the fact it has been in existence for a very long time. It is quite surprising that even though it has been around for so long, people are still only just discovering about it. Not only it makes your food taste delicious, olive oil nutrition is also something that makes it a healthy cooking choice. It is loaded with essential fatty acids and high amounts of antioxidants required by human body on daily basis.
Now a days, olive oil is used not only for cooking, but also in cosmetics, medicines, soaps, etc. Originally, olive oil has its roots belonging to the Mediterranean countries.
Before we get into olive oil benefits, lets take a brief look at what all variety of oil is available in the market and how they are different from each other.
Extra Virgin Olive Oil: This olive oil is obtained after the first pressing of olives and is usually greener than other forms of olive oils available. Extra virgin olive oil has very low acidity and is ideal for dressings, dips and marinades.
Virgin Olive Oil: This form of olive oil is also obtained after first pressing of olives, but its slightly higher in acidity as compared to the extra virgin olive oil. It is also good for dressings and marinades but is not good enough to compete with its extra virgin version.
Olive Oil: This is often a blend of refined oil and virgin oil. The virgin oil added to this cooking oil gives it flavor which is not available in heated and refined oils. Its a good all around oil and is better suited for cooking as it comes with a slightly higher burning point.

Light Olive Oil: This is the refined form of olive oil as it is obtained from the latter pressings of olives. Each subsequent pressing of olives provides light and less flavor oil variations. Here the term light only refers to the color and flavor and has nothing to do with the calorie content. This form of olive oil is suitable for frying and sautéing.
Pomace Olive Oil: The oil that is obtained from the left over flesh and pits after the olives are pressed completely is regarded as pomace olive oil. To release the remaining oil from the olives they are often treated with heat and solvents. The resulting oils are then refined so that they become fit for human consumption, because of all this refining pomace olive oil mostly lacks flavor. This form of olive oil is suitable for frying as it has high burning point.
Early harvest Olive Oil: As the name suggests, this oil is obtained from the olives picked slightly under ripe. The under ripeness of olives makes oil slightly bitter, peppery and extra green. The smaller the olive, the lesser oil it will yield and mostly early harvest olive oil is costlier then its other variants.
Late Harvest Olive Oil: This is the oil obtained from fully matured olives, which results in the production of smooth oil that can be described as fruity and sweetish.
Cold Pressed Olive Oil: Here the olives are pressed without using heat. Though, for most of the olive oil variants heating method is used as it yields more oil but destroys some delicate flavors and olive oil nutrition to some extent. Cold pressing retains all those flavors in the oil that comes after.
