Olive oil has a major place in the Mediterranean diet, and the principal aspect of this diet includes proportionally high consumption of olive oil. Olive oil contains a very high level of monounsaturated fats, most notably oleic acid, which studies suggest may be linked to a reduced risk of coronary heart disease.

There is also evidence that the antioxidants in olive oil improve cholesterol regulation and reduce LDL (bad cholesterol) levels, and that it has other anti-inflammatory effects.

Olive oil is a type of fat extracted from the olive tree which is a traditional tree from the Mediterranean basin. It is produced by crushing whole olive fruits before the oil is extracted. The health benefits of olive oil are wide, a reason why it has been named the Mediterranean miracle.

Types of Olive Oil

Olive oil is used in the cosmetics industry, cooking, pharmaceuticals and even in the making of soaps (such as Castile soap). Olive oil exists in a variety of grades depending on processing. For instance, extra virgin olive oil is considered the premium type. It is produced from the first crushing of olive fruits and is extracted through cold-pressing whereby no chemicals are added. Virgin oil is the second variety, obtained from the second pressing of the fruits and is considered the second-best type. Refined olive oil is obtained from refined virgin olive and it has an acidity level of over 3.3%.

The oil contains phenolic antioxidants, terpenoid and squalene which are all anti-cancer compounds. The oil also has oleic acid which prevents chronic inflammation and reduces the damage free radicals cause to body cells.

Here are some amazing health benefits of olive oil:

1. Olive oil and cancer

One of its main benefits is that olive oil protects against skin, colon and breast cancer. A number of research studies have documented that eating a healthy diet with olive oil as the main source of fat could considerably lower cancer incidence.

This beneficial effect could be attributed to oleic acid, the predominant monounsaturated fatty acid in olive oil. However, it is not excluded that other substances of olive oil, such as antioxidants, flavonoids, polyphenols and squalene may also have a positive influence. Squalene is believed to have a favorable effect on the skin by reducing the incidence of melanomas. And indeed olive oil is one of the top 14 foods that protect against cancer development.

2. Olive oil and Alzheimer’s Disease

Several studies have shown that olive oil can affect the brain and reduce the risk for developing Alzheimer’s disease (AD). This disease is one of the most studied diseases and a significant cause of dementia in the elderly.

Alzheimer’s disease is the most common cause of dementia, which is a brain condition that leads to a decline in an individual’s memory, thinking and reasoning abilities.

In a study published in PLOS One journal, mice with Alzheimer’s disease were given oleuropein aglycone, the main polyphenol found in extra virgin olive oil for 8 weeks. The results showed a significant improvement in the cognitive performance of the mice compared to the group that did not receive the olive oil polyphenol.

The scientists also conducted memory performance tests and noted that in the mouse model, cognitive impairment was completely prevented by oleuropein aglycone administration to the mice.

Another research by the Geriatric Research Educational and Clinical Center, examined the effects of extra virgin olive oil on learning and memory in mice having brain oxidative damage for 6 weeks. The findings suggest that extra virgin olive oil has beneficial effects on learning and memory deficits found in aging and diseases, such as Alzheimer’s and dementia.

3. Olive oil and diabetes

A study published in scientific journal Diabetes Care indicated that any Mediterranean diet which contains olive oil is capable of reducing type II diabetes by over 50%. This is because the oil contains monounsaturated fats like those found in seeds and nuts. These fats are essential in reducing risks of chronic diseases such as diabetes and cancer.

It has been demonstrated that a diet rich in olive oil, low in saturated fats, moderately rich in carbohydrates and soluble fiber from fruit, vegetables, pulses and grains is the most effective approach for diabetics. This type of diet improves blood sugar control and enhances insulin sensitivity.

4. Olive oil and osteoporosis

Olive oil may be used to significantly reduce osteoporosis. Osteoporosis is a condition that means your bones are weak, and you’re more likely to break a bone. ‘Osteoporosis’ literally means ‘porous bones’ and is often referred to as the ‘fragile bone disease‘ with an increased risk of fractures of the hip, spine, and wrist. Osteoporosis is often called a “silent” disease because it has no discernible symptoms until there is a bone fracture.

A study from Madrid University found that people who consumed more olive oil had higher levels of osteocalcin, which is a protein secreted by bone-forming cells. High level of osteocalcin is an indicator of strong bones.

5. Olive oil and blood pressure

A study published in Archives of Internal Medicine journal reports that people on high blood pressure medications may be able to reduce the amount of medicine they take if they substitute extra-virgin olive oil (about 30-40 grams per day) for other types of fats in their diet.

6. Olive oil and cholesterol

According to Mayo Clinic, olive oil contains a strong mix of antioxidants that can lower your “bad” cholesterol (LDL) but leave your “good” cholesterol (HDL) untouched.

Even The Food and Drug Administration (FDA) allows manufacturers of olive oil to claim that “limited but not conclusive evidence suggests that eating about two tablespoons of olive oil daily may reduce the risk of coronary heart disease due to the monounsaturated fat in olive oil”.

7. Olive oil and depression

Olive oil has also been said to control depression. A Spanish study revealed that people who take hydrogenated fats which are mainly found in processed foods had a 48% risk of suffering depression. In addition, the researchers discovered that a higher intake of olive oil and polyunsaturated fats found in fatty fish and vegetable oils was associated with a lower risk of depression.

How Much Olive Oil to Consume

So in essence extra virgin olive oil is an essential type of oil which is recommended for use instead of animal fats where possible. You can greatly enhance the health benefits of olive oil by consuming it with foods that are part of the Mediterranean diet. These anti-inflammatory benefits of extra virgin olive oil don’t depend on consuming a large amount of it. As little as 2 tablespoons of extra virgin olive oil per day have been shown to be associated with significant anti-inflammatory benefits.

You can drizzle olive oil on your bread, make olive oil dressings for salads by combining olive oil with lemon or vinegar, salt, ground pepper, crushed garlic and fresh herbs. Or drizzle olive oil on cooked/baked vegetables or mashed potatoes.

  1. Anita Sheffield says:

    I have made some bread using olive oil and Dove’s gluten free flour. Is this more healthy than using butter or sunflower oil?

    • Jenny says:

      Olive oil Is a healthier option than butter. Olive oil contains only 33% saturated fat while butter is composed of 66% saturated fat. Olive oil has no cholesterol, while a serving of butter has 33mg of cholesterol. Sunflower oil is about two-thirds polyunsaturated fat and is therefore much more prone to damage from heat and light than olive oil, which is about 75% monounsaturated.

    Does heating olive oil cause it to become cholesterol laden?

    • Jenny says:

      One of the questions we are asked most often is what happens when olive oil is heated and/or used for frying. The important thing about cooking with any oil (olive or otherwise) is not to heat the oil over its smoking point. The smoking point refers to the temperature at which a cooking fat or oil begins to break down. The substance smokes or burns, and gives food an unpleasant taste and damages it’s health properties. The smoking point of olive oil is varried between different sources, although studies on this subject show that heats as low as 320˚F (160˚C) can substantially damage the phenols in olive oil (see here – http://www.whfoods.com/genpage.php?tname=dailytip&dbid=261).

  14. Reg Hicks says:

    I have used raw organic EV olive oil for about 18 months but probably not as much as 2 tbsps. a day. Can you advise a recipe for an oil salad dressing, please? I used to holiday in the Algarve and loved their dressing but find the oil on its own not the same. Would it be okay to take this oil direct by the spoonful?

    • Jenny says:

      There are many variations for olive oil salad dressing, but the most basic one is to combine olive oil, lemon juice, salt and pepper. Then taste and adjust amounts. Others like to add garlic or replace the lemon juice with some sort of vinegar, while others add fresh or dried herbs, mustard and a little bit of honey. You can also take olive oil directly by the spoonful.

    • Joe says:

      the healthiest and tastiest recipe of salad…is using 2 spoons of olives oil..2 spoons of lemon…half spoon of apple vinegar…1 spoon of garlic..salt and pepper to taste …mix the ingredients together and put it on your salad..just make sure there is onion in the salad too…the mixture between onion garlic olives oil and lemon and vinegar will give you an awesome taste …very healthy too !

  15. Bradon says:

    I drizzle over pasta and any salad. Always buy Extra Virgin Olive oil

  16. Ma. Jocelyn Bacual says:

    When is olive oil taken, before or after meals?

    • Jenny says:

      It’s best to take olive oil with meals, as there are vitamins that are oil soluble such as A, D, E, and K (rather than water soluble vitamins such as B and C), so consuming the oil with the food will increase the absorption of the oil soluble vitamins.

  17. Marcy G says:

    Whilst science has indeed proven the benefits and superiority of olive oil in our diets, let’s not think that olive oil will totally prevent the risk of cancer. I live in the mediterranean and here like many Europen places the rate of cancer diagnosis is 1in 3. Other factors are in play obviously but I wanted to maje readers aware that whilst a Mediterranean diet is great for our health as is the olive oil in it, it will not totally prevent cancer.

    • Jenny says:

      Nothing can totally prevent cancer. Only reduce the risk. There are other factors that are beyond our control, such as genetics.
