Extra virgin olive oil, Nature’s own elixir
Extra virgin olive oil, the basic condiment of our Mediterranean diet, is an indispensable food for the well-being of the body. Arguably, olive oil is the best superfood in the Mediterranean diet. In addition to its nourishing qualities that come with every small serving, it contains vitamins that are important in combating many cardiovascular diseases. Extra virgin olive oil is undoubtedly the best seasoning fat we have. The great benefits that it holds for our health are due first and foremost to the type of fatty acids that compose it. Like in the vast majority of fats of plant origin, these are essentially unsaturated, i.e., fatty acids that tend to decrease cholesterol levels and in part increase the HDL (high-density lipoprotein), the so-called good cholesterol. This is in contrast to animal fats which are instead formed by a high percentage of saturated fatty acids which, on the contrary, tend to increase cholesterol and in particular LDL (low-density lipoprotein), or bad cholesterol.
For the Greeks the oil was precious: the athletes were olive oil before fighting body-to-body and the winners of the Olympic Games received a crown of olive branches, they received as an anfore oil prize, in addition to the hate Poets and invaluable respect by the citizens. In the Phoenician and Cretan peoples, the oil had initiatory functions and was above all a source of light, not just in the metaphorical sense: the oil lamp had to be spread.
At different times, humans have simultaneously noticed how powerful and beneficial the oil was: the Egyptians thank Isis for having introduced it, the Greeks Athena for having planted it on the acropolis and as the first meal of the day they used to consume the ‘ Acrotinos ‘, meaning bread and oil in wine. The Romans used it for the preparation of numerous recipes, famous for that of Grazio: a pie slice with oil, cheese, flour and honey.
Composition and properties of olive oil
Olive oil is one of the richest oleic acid (about 62%), the most abundant of long-chain monounsaturated fatty acids in our body, with great nutritional and emollient properties for the skin.
In addition to oleic acid, olive oil contains about 15% linoleic acid, 15% palmitic acid and 2% stearic acid.
It also contains an insaponifiable fraction ranging from 1 to 2% and provides this oil with a significant concentration of active antioxidant ingredients including: phenolic compounds, chlorophyll, vitamin E, phytosterols with restorative and anti-inflammatory and squalene, one of the main components of the skin surface.
The characteristics of olive oil and its role in the Mediterranean diet as it is classified, its nutritional qualities, the relationship with dyslipidemia and its anti-diabetic and antitumor properties. Depending on the quality of the olives, their freshness and integrity, the degree of acidity and the processing, olive oils are classified as follows:
Extra Virgin Olive Oil
‘Classical olive oil obtained directly from olives and solely by mechanical processes’; has a free acidity expressed as oleic acid, not more than 0,8 g per 100 g.
Virgin Olive Oil
‘Olive oil obtained directly from olives and solely by means of mechanical processes’; it has a free acidity expressed in oleic acid, up to 2 g per 100 g.
Refined Olive Oil
‘Oil containing exclusively olive oils which have undergone a refining process and oils obtained directly from the olives’; is obtained by the cutting of refined olive oil with virgin olive oil other than sunflower oil, has a free acidity expressed in oleic acid not exceeding 1 g per 100 g and is the result of mixing between a rectified oil, subjected to a chemical process aimed at the elimination of chemical and organoleptic defects, and a virgin olive oil. There is no minimum quantity of virgin olive oil established but is usually a minimum percentage, inserted to improve the color, smell and taste of the oil.
Orujo Olive Oil
‘Oil containing exclusively oils derived from the working of the product obtained after the extraction of olive oil and oils obtained directly from the olives’ / ‘Oil containing exclusively oils derived from the treatment of olive oil and oils obtained directly From the olives‘; Is obtained by the cutting of fine olive oil and virgin olive oil other than sunflower oil and has a free acidity expressed in oleic acid not exceeding 1 g per 100 g.
To have the guarantee that the oil has been squeezed from healthy olives exclusively by mechanical action, at a temperature below 27 degrees, the word ‘virgin’ or ‘extravergine’ must appear on the label. Of the two, the extra virgin is obviously better because it has better values in a number of quality parameters. Instead, a simple olive oil is rectified by chemical processes, which in itself are not dangerous to health but worsening for the quality of the product. In fact, in addition to not having the aromas and flavors of a good extra-virgin, it lacks those molecules that make olive oil a great food to protect your health.
Nutritional qualities of olive oil
Olive oil is particularly rich in oleic acid (monoinsaturate) which decreases ‘bad cholesterol’, LDL, and leaves unchanged or slightly increases ‘good cholesterol’, HDL; Is therefore particularly well suited for dyslipidemia sufferers and particularly for those with elevated LDL cholesterol and low HDL cholesterol values.
Olive oil is excellent raw (and raw is usually consumed) but is also suitable for cooking and frying; In fact, given its high smoke, due to the presence of antioxidants, it is able to remain stable even at high temperatures.
Extra virgin olive oil has the best nutritional qualities, taste and digestibility and has proven to be the most suitable for daily consumption; Contains polyphenols, antioxidants (these substances are almost completely lost if the oil is refined), vitamin E and beneficial fats, monoinstitutional.
Quality oil is guaranteed by the DOP (Protected Designation of Origin) and IGP (Typical Geographical Indication) certification; It is better to prefer when purchasing oil squeezed in the year (the year of squeezing is reported on the label).
The benefits of olive oil
The main feature of olive oil, the one that puts it above all the other fats, animals or plants that there are, is the presence of some molecules including vitamins, alpha and gamma tocoferols and beta chaothenes, phytosterols , squalene and phenolic compounds such as flavonoids, alcohols and phenolic acids. It is a mix of essentially valuable antioxidant substances both for the oil itself as it protects it from irrigation and our health by opposing the formation of free radicals, reactive molecules that naturally form and that so much harm to our cells.
The benefits of extra virgin olive oil for our health are now scientifically proven and numerous studies indicate that its constant use diminishes the risk of cardiovascular disorders and the risk of tumors, especially those of the upper digestive tract. Last but not least, extra virgin olive oil is important in regulating our body’s natural defense system.
Olive oil and dyslipidemia
Extra virgin olive oil, consumed raw, so as to preserve all nutritional qualities, has protective effects against dyslipidemia (it is able to reduce bad cholesterol, LDL, good for the good, HDL) and atherosclerosis, reducing inter alia the risk of heart attack and hypertension, and is able to slow down aging, especially for fatty acids and vitamins (in particular E, A, D and K); It also seems to possess anti-diabetic and antitumor properties.
Anti-diabetic and anti-tumor properties of olive oil, and not only
Antidiabetic properties have been highlighted by an Italian study published on Nutrition & Diabetes conducted by the Sapienza University in Rome; According to this study, extra virgin olive oil could increase the production of hormones that can reduce blood glucose levels and thus have protective effects against diabetes.
Antitumor properties have been highlighted in particular by a Spanish study of breast cancer and an Italian study of colon cancer. The first study, published in Jama International Medicine, was conducted in Spain by the Universities of Pamplona and Madrid, under a Mediterranean Diet Prevention Program (PREDIMED). The second study, published in the Journal of Nutritional Biochemistry, was conducted by the University Campus Bio-Medico in Rome and the Universities of Teramo and Camerino with the collaboration of the Karolinska Institute in Stockholm: according to this study, the intake of oil extra virgin olive oil would act by promoting the production of the CNR1 gene, which has suppressive activity against colon cancer.
According to another study conducted in Sweden, the monounsaturated acids of olive oil play a protective role against the breast of women. Dr. Alicia Wolk from the Karolinska Institute of Stockholm and other Swedish researchers studied 61,471 women between the ages of 40 and 76 between 1987 and 1990. Women were mammograms, completed a self-administered questionnaire on frequency and were followed with care and zeal.
The data were collected by the Swedish Cancer Registry to determine who developed breast cancer during the study period. The data obtained led researchers to highlight a potential protective action of monounsaturated fats: the study was published on the Archives of Internal Medicine.
Extra virgin olive oil is a particularly important component in the nutrition of children: the fats contained therein are able to improve the assimilation of useful substances to ensure balanced development. It is also able to promote intestinal regularity and counteract constipation, reduce the risk of gastric and duodenal ulcers, increase sense of satiety (it would seem to be due to the presence of essential, which can reduce and slow the absorption of glucose, prolonging the feeling of satiety), to reduce the risk of developing gallstones, to counteract respiratory problems (due to the presence of alpha-tocopherol, more active form of vitamin E), and to promote liver function.
Olive oil is a monounsaturated fat composed almost entirely of triglycerides. The most preferred fatty acids are oleic, linoleic and palmitic. Food from multiple virtues contributes to body growth, to the process of myelinating the brain and to the formation of the bones.

According to some studies, its unsaturated fats help to reduce blood glucose levels and it is now proven that a constant, strictly raw, consumption lowers cholesterol.
But how to choose a good extra virgin olive oil for drinking? In general, it is good to opt for extra virgin cold squeezed olive oil. Since it is first pressed, it is the purest form of oil. The oil is naturally formed in the cells of the olives and is then extracted with careful physical or mechanical processes, such as grinding and twisting, which keep the properties intact. Among these, vitamin content is particularly important: extra virgin olive oil contains vitamins A, C and E, the antioxidant and anti-aging effect. It completes the nutrient supply of vitamin B, which regenerates the nervous system. It nourishes the stomach and fights fatigue, but its properties are more numerous:

Oil stains on clothes are tough to get rid of, and often a normal washing machine alone is not enough to permanently eliminate them. Here are 3 tips to remove oil stains from your clothes once and for all.
To remove the oil stains from the clothes, before going to the classic washing machine with the program for very dirty linen, pour a drop of liquid detergent for dishes on the stain. Let it soak for a few moments and then rub it slightly and go to the washing machine with the addition of a little vinegar. If your oil stain is on a sufficiently strong fabric, sprinkle over the household multipurpose cleaning agent, preferably with Marseille soap. Let it soak a few minutes and then proceed with normal washing in the washing machine.
Another method that works to eliminate olive oil stains from the clothes is to sprinkle the stain with the salt and let it work for a few hours. Remove the salt with a teaspoon so that it does not get on other parts of the fabric then pour into the stain a drop of detergent for the dishes and rub with circular movements with a toothbrush. Rinse the stain and proceed to normal washing in the washing machine.

Grapeseed vs. olive oil
Grapples are small seeds in grape berries (Vitis vinifera). Each grape contains one to four grains, which in turn keeps large amounts of oil (15-16%). By-product of the oenological industry, grape seed oil is appreciated both in the cosmetic and in the dietetic-food fields.
Grape seed oil Its main nutritional characteristic is related to the high content of linoleic acid, an essential fatty acid of the omega-6 series. Despite being rich in antioxidant compounds of the phenolic nature, also friends of our health, grape seed oil is altered with heat and should preferably be used raw. To avoid premature deterioration, store it in a cool place, away from light and heat. On the market, however, refined grape oils are found with an extremely high smoke point, which makes them suitable for long-cooking evenings. Unfortunately, while elevating high temperature resistance, on the other hand refining reduces the amount of antioxidant substances present in the food.
Grape seed oil is attributed to hypocholesterolemic properties. Indeed, omega-6 fatty acids have been shown to be effective in lowering the rate of blood cholesterol, lowering the plasma levels of the good HDL and bad LDL fraction. The richness of antioxidants contributes to enhancing its protective properties on the health of the cardiovascular system, however, it is consumed in small doses to avoid too much calories (the consequent overweight would undo all virtues) and not exceed with the addition of omega-6 (which, when not adequately compensated by a diet rich in fish or other omega-3 sources, favors the production of bad eicosanoids).
Vitamin E content is modest compared to that of other vegetable oils, such as wheat germ, corn, soy or sunflower oil. The lack of the antioxidant effect of this vitamin is, however, largely offset by the richness in polyphenols, a peculiar and almost exclusive feature of grape seed oil. Its antioxidant action is widely exploited in cosmetics, protecting against which protects the skin from premature aging, atmospheric agents and free radicals. Grape seed oil applied to the skin also has astringent, firming and stimulating properties on capillary microcirculation.
The following is the nutritional composition stated on the label of a commercial grape seed oil, comparing it to that of an extra virgin olive oil of the same brand.
