Olive oil. Olive oil - benefits and harms How to choose the right quality olive oil


OLIVE OIL

female product

Olive oil is obtained from the fruits of the European olive (= olive tree), from which the stones are previously removed. After squeezing the pulp (the best method is cold pressing, which allows to obtain oil of the quality "Extra virgin olive oil"), the oil is separated from the water, which is 50-60% of the original mass of the pulp. The oil yield is 17-22% depending on the type of olives.

Olive oil is the richest dietary source of monounsaturated fatty acid oleic acid (18:1): its content is up to 74% by weight of the oil. This acid promotes the dissolution of cholesterol plaques in the blood vessels and thus prevents the development of atherosclerosis. In addition, oleic acid, due to its antioxidant properties hinders development coronary heart disease and aging by inhibiting oxidative stress.


Olive oil contains trace amounts of vitamins other than tocopherols and vitamin K. It is high in tocopherols ( vitamin E), especially alpha-tocopherol (in 100 g - 127.7% of the daily requirement) and vitamin K(respectively - 50.2%).

mineral elements there is little in olive oil, but the content chrome it is quite high (in 100 g - 13.6% of the daily requirement).


As with other oils, O days of olive oil's defining nutrients that form the basis of its value as a food ingredient, are fatty acid . So, in the fatty acid composition, unsaturated fatty acids predominate (in 100 g - 204.1% of the daily norm), in particular - monounsaturated fatty acid - oleic (18:1, omega-9): in 100 g - up to 73.7 g.

The content of omega-6 polyunsaturated fatty acids is also quite high (in 100 g - 89.8% of the daily norm), namely linoleic acid (18:2).

Olive oil is a valuable source phytosterols(in 100 g - 433.6% of the daily norm), which are significantly dominated by beta-sitosterol(respectively 300.0% of the daily value). This allows to attribute olive oil To women's products(for more details, see Avocado). High enough also the content delta-5-avenasterol(41.8%) and citrostadienol(21.8%). In general, the composition of olive oil phytosterols includes 7 different substances that harmoniously complement the action of beta-sitosterol.

Carbohydrates, purine bases andOlive oil does not contain oxalic acid.

Significant contribution to antioxidant activity olive oil is also added phenolic compounds and an aliphatic triterpenoid squalene. The total content of phenols in 100 g of oil is 19.6-50.0 mg. The main phenols in olive oil are simple phenols (hydroxytyrosol and p-tyrosol), secoiridoids (oleuropein and ligustroside), and lignans. The squalene content is about 0.7% and it should be said that other foods and oils tend to have squalene levels in the range of 0.002-0.03%.

Simple phenol p-tyrosol (4-(2-hydroxyethyl)-phenol) has antioxidant, anti-ischemic, hemorheological, antihypoxic and antiplatelet properties. The second simple phenol of olive oil is hydroxytyrosol - Also inhibits platelet aggregation (antiplatelet action) and has anti-inflammatory properties.

Aliphatic triterpenoid squalene improves a number of indicators of activity immune system , primarily its ability counteract the growth of cancerous tumors and also enhances overall immunity. Squalene has been shown to be effective against the action of carcinogens, bacteria, fungi, herpes and Epstein-Barr viruses , as well as at leukemia and autoimmune diseases . Squalene has been found to be able to neutralize a number of toxic chemicals.

And it should also be noted that extra virgin olive oil contains significantly more phenols than refined olive oil, and slightly more squalene.

It promotes satiety, helps curb your appetite so you eat less, and boosts gut production of the appetite-regulating hormone CCK. Combined with carbohydrates, this oil helps keep blood glucose and insulin levels low, preventing the body from storing fat.

Olive oil can not only protect the thighs from fat deposits; it can actually increase the body's ability to burn fat. Studies show that foods cooked in olive oil are much more likely to promote fat oxidation than foods rich in saturated fats. Experts suggest that monounsaturated fatty acids turn on genes associated with fat burning and storage.

Vitamins:

By the way, it helps to get rid of excess weight. Extra virgin olive oil contains a lot of antioxidants - polyphenols, which suppress inflammatory processes.

  • virgin oil. It is produced using the same technology as the first, but it may be a little worse. For example, the extraction may not go as fast after harvesting the olives, the acidity of the oil may be higher. Nevertheless, such oil is also tasty and healthy for the waist, and it also saves money.
  • Other grades of olive oil. If you need oil for frying, stewing or other cooking options, choose these standard and inexpensive varieties.
