General Information

Latin Name: Olea europaea

This hub will focus on the benefits of olive oil. But before I get down to this, I would like to give you some information about the olive tree and olives.

The olive tree is an evergreen tree thought to have been existing for over 8000 years. The tree lives for hundreds of years and some have been verified to have been living for over 2000 years. The tree is native to the Mediterranean, Asia and Africa.

Olives are plucked when they are green to dark purple in colour. The colour of the olive fruit does not indicate its ripeness. Many olives start off green and turn black when fully ripe while some olives start green and remain green when ripe while some others start black and remain so when ripe. Olives are picked both unripe and when ripe.

Olives in their natural state are mostly bitter, due to the chemical glycoside that they contain naturally. To overcome this, they have to be processed or cured. There are 5 ways to cure olives viz water curing, brine curing, oil curing, lye curing and salt curing which is also called dry curing.

Uses Of The Olive Tree

The olive tree has been cultivated for a variety of purposes some of which are as given below :

  • For the olive fruit which is used in cooking and for extracting oil.
  • For the olive oil which is used in cooking and as salad oil. It is also used in making soaps, commercial plasters, liniments and dental cement which delay setting time of artificial dentures.
  • For the fine wood, it provides which is used for making pieces of furniture, as it has a beautiful grain and the wood is hard.
  • For the olive leaves that are used in making medicines & medicinal teas etc.
  • The water extracts of the fruit pulp are used in treating rheumatoid arthritis and osteoarthritis.
  • The waste of the olive tree has been found to give 2 and 1/2 times the energy given by burning other types of wood. Its smoke has no negative impact on the environment and the ash can be used as fertilizer for plants.

Black Olives

Is Olive Oil Good For You ?

Olive oil is a light green to golden yellow coloured oil obtained by cold pressing of the olives. Green olives yield the bitter green oil while the black olives yield the less pungent yellow oil.

If you are not sure whether olive oil is good for you or not I place before you some facts!

Olive oil contains 77% monosaturated fatty acids, 14% saturated fatty acids and 9% polyunsaturated acids. It also contains vitamin E, K and vegetable mucilage

1 tablespoon of olive oil contains 120 calories and 14 gms of fat but because most of this fat is monosaturated, it is beneficial to the body and helps to reduce cardiovascular diseases, lowers cholesterol and is easily digested.
Countries like Spain, Italy and Greece have a low incidence of heart disease because these people consume olive oil a lot.

Olive oil can be washed away easily if you spill it on the hands and doesn't need a lot of water and soap. This property of olive oil benefits the body in that it is digested very fast and uses very little energy.

As you can see from the above, the benefits of olive oil are quite amazing.

Olive oil is used in cooking, cosmetics, medicines and soap making. It is also used in religious rituals.

Types Of Olive Oil

Olive oil is available in the following varieties :

  • Extra Virgin Olive Oil

    This is the best in quality obtained from the first pressing of the olives and is the least processed. It has less than 1% acidity.
  • Virgin Olive Oil.

    It is the second pressed oil. The acidity is about 1.5%.
  • Pure & Light Olive Oil

    After pressing some filtering and refining is done. A little Extra virgin Oil is added to the refined olive oil.
  • Extra Light Olive Oil

    Considerable processing is done. It retains a very mild olive flavour.
