The timeless value of olive oil for our health:
Known for its healing and nutritional properties since antiquity, olive oil is one of the key products in the Mediterranean world, and its value for nutrition and health is indisputable.
In ancient Greece, olive oil was an integral part of the daily diet. Depending on the variety and quality of olives, oil fell into the following categories: The excellent quality olive oil was produced from slightly unripe olives and was called “omotrives” or “omfakinon”. Next came the good quality olive oil that was called “deuteron geuma” (i.e. second taste) oil which came from ripe or bruised olives. Another type was the so called “chydaion elaion” (ordinary oil) which was pressed from overripe olives.
Besides diet, olive oil was also used for body and hair care and its application protected the skin from the cold and the sun.
Olive oil has been also renowned for its healing properties since antiquity. Having acknowledged the benefits of olive oil, Homer called it “Golden Liquid” and Hippocrates “Great Healer”. Hippocrates’ Codex includes more than 60 pharmaceutical uses of olive oil. It was ideal for everything, from skin diseases, injuries and burns, to ear inflammations, as well as gynaecological conditions.
References to the therapeutic effects of olive oil can be found in various ancient sources, from Plutarch who mentioned the treatment of mastitis with “hydrelaion” (water and oil), to the inscriptions of Asclepius of Levina and to Theophrastus who presented information about the ingredients and the recipes for the production of aromatic oil.
Great ancient doctors, such as Galen, Dioscorides, and Diocles strongly believed that olive oil can be used to treat many diseases and ensure longevity and quality in everyday life.
The extraordinary health-protective effect of polyphenolic olive oil
As stated in the European Regulation 432/2012 (pages 21 & 22) regarding the health protective action of the olive oil we produce, polyphenols, as well as oleocanthal, oleacein, tyrosol, which are derivatives of hydroxytyrosol, are contained in extra virgin olive oil and have strong antioxidant action. According to this regulation, a daily intake of 20 gr of extra virgin olive oil with high content of polyphenols (more than 5 mg of hydroxytyrosol and its derivatives / 20 gr of oil) contributes to the protection of blood lipids from oxidative stress.
Furthermore, the proven health protective action of olive oil is also based on studies that were conducted by Davis University, USA, and on a wide range of relevant researches, studies and reports from scientists, universities and organisations worldwide, proving that olive oil with high content of polyphenols and its derivatives can prevent and treat various health conditions.
The daily intake of extra virgin olive oil, with high content of polyphenols proves beneficial due to both their individual and combined function. More than 20 phenols and polyphenols have been identified in olive oil and their precious health protective and curative action has been already proven, or is still under investigation (final stage-clinical tests and documentation).
The more typical of them are: Hydroxytyrosol, Tyrosol, Vanilic acid, Caffeic acid, Ferulic acid, Vanilin, p-coumaric acid, o-coumaric acid, Oleacein, Οleuropein and its various aglycones, Ligustroside and its various aglycones. Indicatively, we mention:
Biophenol highly absorbable, with ten times more antioxidant action than green tea. The most powerful antioxidant in olive oil. It protects the central nervous system cells from exposure to toxins. Based on the above mentioned actions, tyrosol is subject of studies (with strong indications of high therapeutic value) in Alzheimer's and Parkinson's disease. Additionally, one of its benefits is its ability to slow down cell aging and activate a group of genes responsible for longevity. Also, tyrosol is the main compound of olive oil that helps reduce LDL, also called "bad cholesterol". Its antioxidant action can also help in cutting the chain of free radical attacks, which can affect DNA and lead to cardiovascular disease or cancer.
Extremely strong antioxidant activity and strong cardiovascular system protection properties. According to various researches and studies, hydroxytyrosol can destroy cancer cells and prevent them from proliferating.
Benefits include having an anti-inflammatory effect similar to Ibuprofen, inhibiting the progression of Alzheimer’s disease, COX1 and COX2, treating rheumatoid arthritis, anti-tumor activity and antioxidant action. Longtime intake of low doses, offers protection against cardiovascular diseases and aging. Oleocanthal is responsible for the pungency, which is characteristic of early harvest olive oil (agourelaio).
With a structure similar to Oleocanthal, Oleacein is a derivative of hydroxytyrosol and is the most powerful antioxidant in olive oil.
Strong antioxidant activity, protection against Alzheimer's disease.
Antioxidant & antimetastatic action.
Also, in significant amounts, we find tocopherols, squalene, oleic acid, b-carotene and a large number of other ingredients, with extraordinary health protective and curing - healing action, that have either been already proven or they are in the final process of completing clinical researches (having already given promising and miraculous first results).
In fact, new ingredients such as oleokoronal, oleomissional and so on, with health protective and therapeutic action, are still being discovered and we are still trying to understand their precise mechanism of action. After thousand of years of use by man and after at least a century of modern research, olive oil continues to surprise us with its secrets.
Τhe International Recognition
Since 2004 in the United States, the Food and Drug Administration (FDA), in response to a request from the North American Olive Oil Association, has approved a special health claim for olive oil labels, which has led to a steady increase in olive oil consumption by Americans, by almost 5% per year.
The claim states that daily consumption of about 2 tablespoons or 23 grams of olive oil can reduce the risk of coronary heart disease. Sufficient evidence obtained by the FDA led to the approval of the health claim and concludes that monounsatured fatty acids, naturally present in olive oil, can protect against the occurrence of heart disease.
The scientific data reviewed by the FDA, has shown that replacing saturated fatty acids with monounsaturated fatty acids reduced the levels of total and LDL cholesterol in the serum, which are known to increase the risk of coronary artery disease. Based on their findings, the FDA concluded that a minimum daily intake of 17.5 grams of monounsaturated fatty acids from olive oil (contained in about 2 tablespoons) is required to have a positive effect on the reduction of coronary heart disease. To reduce the risk of heart disease, the claim further states that olive oil should replace an equivalent amount of saturated fat in the diet.
Subsequently, since 2012, the European Food Safety Authority (EFSA) officially recognized that the daily consumption of high-polyphenol (Hydroxytyrosol and its derivatives) olive oil prevents the oxidation of bad cholesterol and thus prevents the formation of atherosclerotic plaque in the blood vessels, while protecting the body from the occurrence of cardiovascular disease (Ε.U. 432/2012 pages 21 & 22):
«Polyphenols of olive oil contribute to the protection of blood lipids from oxidative stress. The claim may only be used for olive oil containing at least 5 mg of hydroxytyrosol and its derivatives (for example, complex of Oleuropein and tyrosol) per 20 g of olive oil. In order to use this claim, the consumer should be given the information that the beneficial effects are ensured by the daily intake of 20 g of olive oil.»
Nowadays, a great number of scientific researches, studies and reports by scientists, universities, foundations and organizations worldwide, have revealed and confirmed the extraordinary health-protective and therapeutic action of olive oil with a high content of phenols and polyphenols and other types of beneficial active natural substances, such as tocopherols, flavonoids (e.g. apigenin), lignans (e.g., pinoresinol, acetoxypinoresinol), secoiridoids etc. Among others, it appears that:
