Is Extra Virgin Olive Oil Better?

Extra Virgin Olive Oil is the highest quality oil available today. It is extracted from olives without any chemical or heat treatment. Extra virgin olive oil has many special benefits with diseases such as: cardiovascular disease, metabolic syndrome, Alzheimer's disease...

Extra Virgin Olive Oil, also known as extra virgin olive oil (EVOO) is extracted from olives by cold pressing process. Olive oil is only 1% acid. It is the oil that comes from the first pressing of the olives and is considered the best olive oil.
1.2. Nutritional composition of Extra Virgin Olive Oil This is quite a nutritious oil. It contains moderate amounts of vitamin E and vitamin K. At the same time, the healthy fat content of this oil is quite rich and abundant. In a tablespoon equivalent to 13.5 grams of olive oil contains: 14% saturated fat, 73% monounsaturated fat mainly oleic acid, 13% vitamin E, 7% vitamin K. The most remarkable thing about olive oil that makes it so important is that the content of antioxidants in the oil is extremely diverse.
Antioxidants are biologically active and some of them help the body fight off serious diseases. The oil's main antioxidants include the anti-inflammatory oleocanthal, as well as oleuropein, a substance that protects LDL (bad) cholesterol from oxidation.
Some people have criticized olive oil because it has a high omega-6 to omega-3 ratio (10:1). However, its total polyunsaturated fat content is still relatively low, so this is not a cause for concern.

2.1. Extra virgin olive oil contains anti-inflammatory substances Chronic inflammation is one of the leading causes of diseases such as heart disease, cancer, metabolic syndrome, diabetes and arthritis. Some scientists have speculated that Extra Virgin olive oil has good anti-inflammatory properties. Furthermore, the oleic acid component in the oil has a prominent function of reducing inflammatory markers such as C-reactive protein.

However, scientists have also found that the anti-inflammatory effects of the oil are also due to antioxidants. Oleocanthal has been shown to work like ibuprofen, a popular anti-inflammatory drug. Several studies have demonstrated that every 50ml of oleocanthal in extra virgin olive oil has the same effect as 10% of a dose of ibuprofen. In addition, studies have also shown that substances in olive oil can reduce the expression of genes and proteins that mediate inflammation.
2.2. Extra Virgin Olive Oil and Cardiovascular Disease Cardiovascular disease and stroke are among the most common causes of death in the world. However, many observational studies show a low prevalence of this disease in countries around the Mediterranean Sea. The reason is that the Mediterranean diet helps prevent heart disease and reduces heart attacks, strokes and deaths by up to 30%.
Extra virgin olive oil protects against heart disease through multiple mechanisms:
Reduces inflammation. Olive oil protects against inflammation - this is a key factor in heart disease. Reduces the oxidation of LDL (bad) cholesterol. The oil protects LDL particles from oxidative damage, which is a major factor in the development of heart disease. Improve blood vessel health. Olive oil improves the function of the endothelium, which is the lining of blood vessels. Helps manage blood clotting. Some research suggests that olive oil may help prevent unwanted blood clotting. This is a major factor in heart attacks and strokes. Hypotension . A study in patients with hypertension found that olive oil significantly reduced blood pressure and reduced the need for blood pressure medication by 48%. 2.3. Some other benefits of Extra Virgin Olive Oil Extra Virgin Olive Oil and Cancer Cancer is a common cause of death and it is characterized by uncontrolled growth of cells. Studies have shown that people living in Mediterranean countries have a fairly low risk of cancer, and some scientists have speculated that olive oil has something to do with the problem.

The potential of cancer is oxidative damage caused by harmful molecules - free radicals. The composition of Extra Virgin olive oil contains many antioxidants that reduce the effects of this process.
Furthermore, the oleic acid in olive oil is also highly antioxidant and has been shown to have beneficial effects on genes associated with cancer. There have been many test-tube studies that have observed that compounds in olive oil can help fight cancer at the molecular level.
Extra Virgin Olive Oil and Alzheimer's Disease Alzheimer's disease is the most common neurodegenerative disease in the world and a leading cause of dementia. A characteristic feature of Alzheimer's disease is the accumulation of protein dystrophies - beta-amyloid plaques in certain nerve cells in the brain. A study conducted on rats observed that certain substances in olive oil can help clear these plaques. In addition, research has shown that a Mediterranean diet rich in Extra Virgin olive oil may help improve brain function as well as reduce the risk of cognitive decline.

During processing, fatty acids can be oxidized. Then the double bonds in the oil molecule are broken. Because, these fats are not resistant to high temperatures.
Extra Virgin Olive Oil contains mostly monounsaturated fatty acids, has only one double bond and is highly heat resistant. In one study, researchers heated extra virgin olive oil to 180 degrees Celsius for 36 hours. Oil is highly resistant to damage. Or another study used olive oil for deep frying, and it took 24-27 hours for it to reach the level of damage that is considered harmful.

In short, eating olive oil is extremely healthy. Especially for people who have heart disease, or are at risk of developing this disease, Extra Virgin olive oil is an indispensable food in the daily diet.
