A Delicious Companion To Good Health: The Olive Oil Story

The health benefits of olive oil in the Mediterranean diet has become more than a novel observation. Clinical research is substantiating healthy benefits, but the gourmet tastes and flavors are bonuses well worth mentioning too.

Highly favored as a cooking oil, or for use in a variety of classic dressings, olive oil is being touted in some quarters as a delicious companion to good health. Research on the health benefits of olive oil is impressive, so is the affects of the Mediterranean diet.

Recent Findings

Olive Oil as a Cholesterol Reducer

Compared to American cuisine, especially the snack and fast foods prevalent in the US, the Mediterranean Diet has intrigued the medical world. The European Journal of Clinical Nutrition has published findings that indicate the introduction of olive oil into our regular diet has demonstrated a reduction in LDL cholesterol (bad cholesterol). This is significant because once LDL cholesterol has oxidized it often results in artery rigidity and accompanying heart disease.

Olive Oil in Cancer Prevention

In a comparison study at the University Hospital Germans Trias Pujol in Barcelona there seems to be an indication that the health benefits of olive oil may also be useful in the prevention or slowing of cancer cells. In the study, lab rats were introduced to a carcinogen that resulted in cancerous tumors. The study provides evidence that a diet similar to the Mediterranean diet, rich in olive oil prevents colonic carcinogenesis reducing precancerous tissue which resulted in fewer tumors when compared to a controlled sample of rats ingesting foods containing other types of cooking oils.

Researchers at Oxford University in England have seen indications that olive oil may actually be as good for our digestive system as fresh fruit and vegetables in preventing or reducing the incidence of colon cancer. While red meat seems to be linked to the development of colon cancer, fish and olive oil seemed to reduce the incidence of colon cancer. The reasons behind this phenomena are still being considered, but it is believed that the olive oil may help regulate the bile acid in the stomach while increasing useful enzymes within the stomach that contribute to optimal colon health.

Olive Oil and Heart Health

The American Heart Association has also noted that consumption of olive oil has “clear health benefits”.

Olive Oil and Lower Blood Pressure

By substituting virgin olive oil for other fats within your diet, the Archives of Internal Medicine indicates a substantial reduction in drug dosage requirements for the management of high blood pressure. Initial findings indicate dosage reductions could be as high as 50%.

Additional Findings

By lowering the level of LDL cholesterol (bad cholesterol) there is an increase of the HDL cholesterol (good cholesterol). The antioxidant effects of olive oil have also been widely reported and are effective in reducing free radicals within the body that may prove to be a causal agent in pre cancerous and cancerous growth.

Additional health benefits of olive oil may be found in a Mediterranean diet which explores the varied uses of olive oil in both food preparation as well as additional balanced meal choices. Combined, olive oil and appropriate food choice seem to enhance the overall health of those subscribing to the Mediterranean diet.

Final Word

While studies remain ongoing, it is encouraging to note that something that has long been noted for good taste may also be a link to positive health benefits and longevity of life. An adaptation of the Mediterranean diet may be a healthy, yet palatable change well worth considering.

Olive Oils Explained

Olives and their oil are some of the oldest foods around today. Cultivation of the olive has been traced back as far as 5000 BC. It really is quite surprising, considering it has been around for so long, that many people are still only just discovering it. Not only is it delicious but being loaded with essential fatty acids and high in antioxidants, it is also incredibly healthy. Below is an explanation of some of the common types of olive oil and terms used to describe them.

Extra Virgin Olive Oil: Is the oil obtained from the first pressing of the olives. It is usually greener than other olive oils, and has very low acidity (it may not exceed .8%). It is ideal for use in dressings, dips and marinades.

Virgin Olive Oil: Is also obtained from the first pressing of the olives, although is slightly higher in acidity (it may not exceed 2.0%). It is very good oil but just not good enough to be designated extra virgin.

Olive Oil: Often consists of a blend of refined oil and virgin oil. The virgin oil gives it the flavour that the heat treated and refined oil lacks. A good all around oil, better suited to cooking as it has a slightly higher burning point than the virgins.

Light Olive Oil: Is refined oil obtained from the latter pressings. Each subsequent press of the olives, results in lighter and less flavourful oil. The term 'light' refers only to the colour and flavour and not the caloric content. It is again suitable for frying or saut'ing.

Pomace Olive Oil: Is oil obtained from the left over flesh and pits after being pressed. To release the remaining oil out of this (pomace) it is often treated with solvents and heat. The resulting oils are then refined to be fit for human consumption; because of this refining it can lack flavour. It is suitable for frying as it has quite a high burning point, but personally I hesitate to use it.

Early Harvest: Simply refers to the fact that the fruit was picked slightly under ripe. The under ripeness of the olive results in a sought after oil that is slightly bitter, peppery and very green. The smaller olives yield less oil and as such Early Harvest oils often sell for more.

Late Harvest: Is oil obtained from fully mature olives and results in a smooth oil that may be described as sweetish and fruity.

Cold Pressed: Refers to the fact that the olives were pressed without the use of heat. Olives that are pressed when heated yield more oil but the heat can destroy some of the delicate flavours that are retained when cold pressed.
