Vegetable oil: what is it, what is the harm and benefit, what is the most useful?
Oils from various plants have been used for a long time. The scope of their application is quite wide - from the preparation of various dishes to the creation of cosmetics for body and hair care. In each nation, preference was given to a certain type of oil. Slavs prepared and used hemp oil, Greeks and Egyptians used olive oil, Asians and Orientals traditionally used palm oil, Africans used coconut oil.
What is it and what does it look like?
Oils of various plants have been used by mankind since time immemorial. In ancient Egypt, valuable oils of olive, sandalwood, cardamom and others were collected, using them to heal various diseases, as medicines and the basis for incense. With their help, healing balms were prepared and mummifications were made.
Ancient people used oils for food, knowing about their nutritional properties. The Hellenes made sea buckthorn compounds, using them in military campaigns as a means of disinfecting wounds. In the 17th century, exotic sunflower seed oil was brought to Europe from South America, a new continent, and with it amaranth hard oil. So the familiar product came to Russia. Before that, they used sesame, adding it to soups, cereals and pastries.Traditionally, oils are divided into edible and essential oils, and also differ in purpose, the original raw material from which the product is extracted, and manufacturing technology.
A large supply of vegetable fat in oilseeds is an inexhaustible source of useful elements and minerals. Often it is extracted from seeds, since most of it is contained there. There are liquid and solid forms. Moreover, oils in liquid form are the most common.
Solid fats are also called butters. These can be natural oils, such as coconut, argan, shea butter, or their synthetic counterparts. In any case, their consistency softens and becomes liquid at 30 degrees.
Oils are also distinguished by the way they are produced. The safest of them is cold pressing or pressing. Oil parts (selected seeds) are placed under a press and crushed, and the resulting raw materials are collected, filtered and distributed in containers. The yield of oil in this production method is 26%. The product is labeled "extra" - the highest quality.
The next way to produce oil is pressing. For its production, ordinary plant seeds are taken, which are heated in special ovens before pressing. The yield of the finished product is much higher - 45%. But the quality of the oil is much lower than the previous one.
The most inexpensive and conservative method is the so-called extraction. For him, organic matter of low quality is used. The method involves the use of chemical elements - petroleum products to extract oil by dissolution and condensation. Next, the oils are extracted with steam and the residues of harmful substances are removed with alkali.
The extracted oil becomes refined, bypassing several purification steps: evaporation (hydration), freezing, refining and deodorization.
In the hydrogenation phase, the oil base is deprived of phospholipids, which precipitate into a cloudy precipitate during long storage. Freezing removes harmful resins and wax. Refining completely cleans the oil from any impurities, neutralizes the color. Deodorization additionally removes odor from the product.
A plant product obtained by pressing, frozen and peeled, is used for nutrition. The most popular is sunflower oil, made from sunflower seeds. Then - olive, rich in monounsaturated fats, resistant to high temperatures.
Benefit and harm
The nutritional and healing value of oils is justified by the presence of fatty acids and other useful elements in them.
Saturated acids have antiseptic and bactericidal effects, give the product unique properties to destroy pathogenic microflora, and also take part in the process of building collagen and elastin fibers. These fats are found in sesame, soybean and cottonseed oils. Therefore, these products are used in cosmetology to enrich compositions, emulsions and elixirs.
Monounsaturated fatty acids are responsible for normal metabolism, cleanse the walls of blood vessels, break down cholesterol plaques, adhesions, and help restore cell membranes. The hepatoprotective effect is due to the presence of palmitoleic acid of the Omega-7 class, as well as oleic acids contained in grape, sesame, rapeseed and olive oils.
Polyunsaturated fatty acids - alpha and gamma linoleic, normalize the hormonal background in the body, protect blood vessels from atherosclerosis. They are rich in sunflower, mustard, corn, rapeseed, cedar, soybean and other oils.
Among other things, plant oils contain a number of essential substances and elements: vitamins, which include D, B, A, E, nicotinamides and phospholipids (lecithin). Phosphatidylcholine protects the liver from harmful glycogens and breakdown products, and also promotes the breakdown of fats by participating in carbohydrate metabolism.
Many fatty acids are not produced in the human body. Therefore, they must be obtained from the outside along with food. Fatty acids have a pronounced therapeutic effect:
- are lipotropic, reduce the presence of fat in liver cells;
- support vascular turgor, preventing cholesterol from settling;
- restore cells, being the building material of membranes and smooth muscles;
- normalize the formation and outflow of bile;
- are powerful antioxidants, remove toxins, free radicals and decay products;
- cure tumors, including malignant and other neoplasms;
- smooth out menopause, normalizing hormonal levels;
- treat constipation and improve intestinal motility;
- prolong youth and protect against wrinkles;
- restore brain cells, improve the conductivity of neurons;
- restore bone structure and cartilage tissue after injuries and surgery;
- stabilize the immune system and mental state.
This is not the whole list of useful qualities of oils for the health of the human body.
Vegetable oils are used to treat many diseases.
- Pancreatitis and other pathologies of the pancreas. A feature of the disease is the poor absorption of fats, so oils should be used exclusively in medicinal doses and only in the recovery stage.
- Oils should be used with caution with various forms of diabetes. A low-carbohydrate diet can lead to a deficiency of acids involved in the production of hormones, including insulin. By adjusting the daily intake of a plant product, you can significantly improve the condition of diabetic patients. Moreover, the consumption rate should not exceed two tablespoons. The inhabitants of the Mediterranean rarely suffer from such diseases caused by metabolic disorders. As a result of research, it was possible to find out that this is facilitated by the constant consumption of olive oil, as well as products and dishes containing it.
It should be introduced into the diet of diabetics gradually, with great care, only in small doses. But these doses can work real miracles, and in many cases contribute to the complete healing of the disease.
- For diseases of the digestive system and gastrointestinal tract, for removing toxins, cleansing the large intestine, as well as for constipation and hemorrhoids.
- For hypertension, hypotension and any vascular problems, including disorders of the circulatory system and heart, as well as heart attacks, strokes and other diseases. Fats make the vessels elastic, restoring their structure, due to which the blood flow normalizes and the pressure returns to normal.
- For gout and arthritis in complex therapy and as an auxiliary complex.
- For the treatment of the thyroid gland and normalization of the endocrine system.
- For colds and viral infections as a tonic.
- As a massage base for the treatment of infringements, backache and rheumatic joint pains, as well as for sciatica and other inflammatory diseases, oils enriched with esters with healing properties are used.
- In cosmetology the use of vegetable oils is very wide. In regenerative medicine, it is used as a regenerating agent that restores the structure of cells and tissues. In folk medicine, it is used as part of external and internal means, as well as in complex methods of treating certain diseases.
There are practically no contraindications in the use of vegetable oil. The main condition is its moderate consumption.
Still, there are a number of features that you need to know.
- For deep-frying and frying, an unrefined product should not be used. This is fraught with harmful consequences, since when heated, chemicals and carcinogens are released from the oil. Once in the human body, they can cause irreversible pathological processes. It is best to use purified refined oil.
- Do not boil or heat the oil strongly before use. You should know and take into account smoke points, which are critical marks - indicators of a decrease in the level of usefulness of the product. Beyond this point, most of the useful substances evaporate. Therefore, it is advisable to use the herbal product in a cold form.
- The optimum heating temperature is 80 degrees Celsius. Beyond this point in the oil, the composition is broken. And for different oils, this figure fluctuates.For grape seed oil, as well as rapeseed and corn oil - 160 degrees, for sunflower and soybean - 170, for olive and peanut - 210-220, for palm - up to 240 degrees Celsius.
- It is especially dangerous to reuse oil without purification. This composition is one hundred percent holder of carcinogens.
- An unrefined product is prone to rapid turbidity with loss of nutrients. Four months after production and bottling, such oil becomes cloudy, precipitates and becomes bitter. This happens with refined oil if stored improperly. It is impossible to use a spoiled product for cooking.
- The daily oil requirement should not be exceeded. It averages 100-110 grams. Excessive consumption of fats can provoke the appearance of excess cholesterol, as well as increase body weight, which is highly undesirable, especially for heart and vascular problems.
- In the active phase of pancreatitis, cholecystitis, stomach ulcers, gastritis, as well as in renal failure and during an exacerbation, the oil should be temporarily excluded from use.
- With individual intolerance to the product and allergies.
It should be remembered that with immoderate and improper use, even the most useful product can be harmful.
What oil is considered the most useful?
In the chain of necessary oils, olive is in the first place. In its usual form, it is similar to sunflower, but when heated, unlike it, it does not lose its qualities and properties. Oleic fats do not oxidize and do not break down under the influence of temperatures.
Sunflower seed oil contains many more useful minerals and vitamins than other products.Therefore, it can be attributed to useful products. Its main advantage and advantage is the content of a powerful antioxidant - tocopherol, in sufficient quantities.
Next comes flax oil - the lowest calorie product in this line. It is often used in the dietary aspect, and also in cosmetology. It normalizes the level of hormones, suitable for both women and men. Nutritionists advise taking two tablespoons of butter with cottage cheese daily - this is the best preventive measure against the formation of cancer cells. This method has fully proved its worth, thanks to the research of D. Budwig. It is successfully used to treat autoimmune and heart diseases, as well as age-related changes in menopause.
Sesame oil is rich in potassium and calcium. It is useful to take it to restore bone and cartilage tissue, as well as for gout and other diseases of the bone system and connective tissue. Often a dark product is used because it is more saturated in composition. The oil is not subject to heating, it is seasoned with vegetables, first and second courses, and is used exclusively cold.
Mustard oil is a natural preservative, as it contains essential oils along with fatty acids. When heated, it does not lose its properties, and baking with it is covered with a crispy, not stale crust.
Chemical composition
Oils are made up of chemical elements:
- arachidonic, palmitic, linoleic, stearic and oleic acids;
- vitamin A (retinol), improves vision, general condition of the skin, its structure and vascular bed;
- vitamin D positively affecting the functioning of the thyroid gland, participating in the regulation of the endocrine and nervous systems, as well as binding calcium in the bone system, preventing its loss and leaching;
- vitamin E (tocopherol), which removes decay products, toxins and poisons from the human body;
- vitamin F, which helps strengthen connective tissue and smooth muscle fibers, restores connections between neurons, thereby improving cognitive abilities;
- omega-3 and -6 fatty acids in the content of vitamin F are essential fats for the restoration of nerves and the treatment of neurological diseases;
- presence of minerals potassium, calcium, boron, iron, copper, molybdenum, selenium, zinc, phosphorus, magnesium, chromium and manganese makes oil the most useful product;
- esters and polyesters, proteins, lecithin, tannins and other micro and macro elements, including essential acids, saturate the body, replenishing the daily need for substances necessary for normal human life.
Contrary to popular belief, vegetable oils do not contain cholesterol. Cholesterol is a substance, a hormone that is produced by the human body under the influence of certain elements. Its presence is necessary for the body, but a deficiency or excess is harmful. Excessive production of cholesterol can clog blood vessels, which can adversely affect the general condition of the body. Fatty acids in large quantities may well provoke the production of cholesterol.
Experts recommend alternating oils, using them alternately. In the arsenal of a good housewife, there should always be 3-4 of their types.
Kinds
There are several types of vegetable oils. All of them depend on the method of production.
Unrefined sunflower oil produced by squeezing the seeds under a press with preheating. The waste cake is used as a feed base in animal husbandry. Such a product has a pronounced smell of seeds, has a mild taste of roasted seeds. Unrefined oil contains more nutrients than refined oil. It contains 70 mg of vitamin E per 100 g, while olive contains only 25 mg. It contains various impurities, soaps, pigments and odorants, the constant use of which is undesirable for health. Crude oil is added to salads and other dishes, using it exclusively cold.
The table of technical conditions GOST 1129-93 indicates that in the second grade, the slight smell of mustiness and bitter taste characteristic of sunflower oil are the norm, which is quite acceptable in a natural product.
- Refined or purified oil is odorless and tasteless. The derived mass is subjected to a cleaning process using chemical reagents. Passing through several cleaning methods, including manual and mechanical, the raw material is gradually freed from color, taste, even the density changes. All that remains is the fatty base, which is resistant to heat and easy to prepare. Therefore, this waste oil is used in cooking for cooking hot dishes and preservation.
- During the hydrogenation process, vegetable oils become solid. Hydrogenated products - butter or margarine - are widely used in the food industry.For their production, the liquid base is first treated with nickel oxide, then placed in a special chamber, where the mixture is hydrolyzed under the influence of hydrogen and high pressure. Further, emulsifiers and starch are introduced into the composition, they are cleaned of color and odor. It turns out solid fat - the basis to which flavors, dyes and other ingredients can be added to give the product the desired qualities and properties. Hydrogenated fats are transsomers that replace saturated fats in the body.
Such a substitution does not bode well and can adversely affect health. Regular use of such a product can cause a number of diseases due to the accumulation of low-density cholesterol in the body.
- Deodorized oil is prepared exclusively in production conditions, where it is cleaned with hot steam in a special chamber in the absence of oxygen. In the process, there is a release from color, smell, taste, sediment. At the same time, the vitamin complex, minerals and useful elements remain. This oil is almost colorless, well and long stored, suitable for heating and deep-frying.
All types of plant products are produced in accordance with international quality standards and are quite suitable for consumption.

Oil can also remove ticks by preheating it. A few drops are enough to kill a tick. Then, with twisting movements, it is carefully removed from the body with tweezers.
What can be replaced?
The effectiveness of vegetable oil is obvious. There are its analogues - saturated fats, while vegetable fats are unsaturated. Saturated fats are considered less likely to oxidize when heated and are therefore safer to use. The question is debatable, but for everyone who thinks so, there is an alternative option - butter, ghee and animal fat. There is also margarine, but it contains trans fats, so its constant use is unsafe for health.
Butter is almost 69% stable fat. It contains vitamins, fatty acids, but due to the fact that the product contains proteins and sugar, it has a low smoke point. This prevents it from being used at high temperatures. You can’t cook with such oil - it will simply burn.
Ghee is a traditional Indian dairy product. The technology of its production is based on the ancient method of rendering in order to separate the milk protein from the fat base. The resulting fat is resistant to heat and is used for cooking various dishes.
Animal fats used in cooking - goose and duck, chicken, mutton, pork and beef. They are also stable, hence subject to temperature influences. You can safely fry, cook and bake on them without fear of harmful carcinogens. But there is one feature: you can gain excess weight from the abuse of animal fats, so they are of little use for dietary nutrition.
A separate topic will be medicinal fats of animal origin: mink, nutria, badger, bear, goat, sheep, camel and others. They are taken orally in microdoses. Long-term use guarantees a stable therapeutic effect in many diseases.It is enough to take a match head of bear fat daily for two weeks to replace the course of treatment with hepatoprotectors.
Bear fat cleanses the blood and liver, removes toxins and normalizes the activity of the stomach and intestines. Mink fat has a beneficial effect on bone tissue and blood vessels. Animal products are used in cosmetology as additives in creams and ointments. External use of creams based on animal fats is carried out in courses due to the specificity and richness of the compositions.
How and how much to store?
If the rules for storing a vegetable oil product are not followed, cases of poisoning are possible. Therefore, it is necessary to store it correctly - in a dark place, at a stable temperature not higher than 23 degrees, in a strong container protected from light. The shelf life of an open product should not exceed four months, provided it is in a refrigerator.
At room temperature, the period is much lower and is about a month. The unrefined product is stored even less - a maximum of two weeks. After the expiration date, the oil becomes bitter and precipitates. This product should not be used.
High-quality vegetable oil is very useful for the human body. It improves the taste and nutritional qualities of dishes, and is also able to replenish the energy supply of nutrients and elements. In addition, it is used for medicinal purposes and in folk medicine.
The highest quality product is cold pressed oil. Healthy oils include olive and sunflower. It is preferable to use an unrefined product without heating. You can replace this product with margarine, butter, butters and animal fats. The product has no synthetic analogues.
The product should be consumed within a month from the date of opening the bottle. Store in dense dark glass, protected from light, in a dry place. Opened product should be stored in the refrigerator. Vegetable oils are good to combine, combine and alternate.
For cooking, frying and deep-frying, a neutral product, free of impurities, is more suitable. For cold dishes and salads - unrefined oils that have the taste and properties of the original product. In order for a vegetable oil remedy to have its beneficial effect, it is necessary to take into account its features, as well as adhere to consumption restrictions.
