Is there cholesterol in sunflower oil: content in vegetable oils

Fatty acids in oils and their effect on the body

Saturated fatty acids (SFAs) , in addition to their unconditional benefits - participation in the synthesis of bile, sex and adrenal hormones, vitamin D - in excessive quantities can cause serious harm: increase cholesterol levels in the blood, promote the formation of fatty plaques on the walls of blood vessels and the development of atherosclerosis.

Class of unsaturated fatty acids:

1. Monounsaturated (MUFA). The oils contain mostly oleic omega-9, which regulates lipid metabolism, lowering cholesterol levels.
2. Polyunsaturated (PUFA).

The body is not capable of producing polyenoic acids on its own and requires their supply from the outside. In oils they are presented mainly:

• linoleic omega-6 – a precursor to γ-linolenic acid, which stimulates the elimination of toxins, low-density lipoproteins and cholesterol, reducing their levels;
• α-linolenic omega-3 - from it the body synthesizes essential DHA and EPA, which regulate lipoprotein metabolism, normalize their parameters, reduce blood viscosity, and activate metabolism.

To maintain health, the ideal ratio of omega-3 to omega-6 PUFAs in food should be 1:4 – 1:5.

There are more than 240 types of vegetable oils. But in Russia and Ukraine the most common is sunflower oil. Why is sunflower oil traditionally present in Russian cuisine, and how does it differ from other vegetable oils? Is eating it beneficial or harmful?

Increased interest in healthy eating is a characteristic feature of our time. The modern view of food from the point of view of its effect on health does not ignore this popular product in our country. Is there cholesterol in sunflower oil? What is the connection between sunflower oil and cholesterol, the excess content of which is undesirable in the human body?

A short excursion into history

The plant was brought to Russia almost three hundred years ago, but for a long time it was grown exclusively for decorative purposes.
Luxurious yellow flowers, always directed towards the sun, enlivened not only palace flower beds and landowners' estates. For decades, sunflower conquered the space of the Russian Empire. The North Caucasus, Kuban, and Volga region welcomed it into their open spaces. In Ukraine, where the “sun” settled near every hut, peasant women and merchant women not only enjoyed its flowering, but a new entertainment – ​​“clicking seeds” – diversified their holidays on the zavalinka.

While Europe continued to admire sunflowers, which inspired Vincent van Gogh to create an amazing series of paintings of the same name, in Russia they came up with a more practical use for them. Serf peasant Daniil Bokarev invented a method for obtaining oil from sunflower seeds. And soon the first oil mill appeared on the territory of what is now the Belgorod region.

The widespread use of sunflower oil in the mid-19th century was facilitated by the fact that the Orthodox Church recognized it as a Lenten product. This second name even stuck – vegetable oil. Sunflower crops in Russia at the beginning of the last century occupied an area of ​​about a million hectares. Vegetable oil became a national product and began to be exported.

Is there cholesterol in vegetable oil?

Cholesterol is an organic compound of the steroid class, which is necessarily present in products of animal origin. It owes its name to its discovery - it was first isolated from gallstones and is translated as solid bile.

In our body it plays an important role, ensuring the stability of cell membranes, participates in the production of bile acids, hormones, vitamin D. For the most part (up to 80%) the required amount is produced by our liver and other internal organs, the rest we get from food. Excess cholesterol in the blood increases the risk of atherosclerosis and the development of cardiovascular diseases.

In principle, excess cholesterol in the blood can appear in two cases:

1. Do not consume food containing large amounts of it if consumed in moderation;
2. As a result of lipid metabolism disorders, which, in turn, can be provoked by harmful substances received with food.

According to the official version, plants do not contain cholesterol. Therefore, the cholesterol content in sunflower oil is zero. However, in the reference book “Fats and Oils. Production, composition and properties, application", 2007 edition, author R. O'Brien indicates that one kg of sunflower oil contains from 8 mg to 44 mg of cholesterol. For comparison, the cholesterol content in pork fat is (3500±500) mg/kg.

Be that as it may, sunflower oil cannot be considered a serious supplier of cholesterol. If sunflower oil contains cholesterol, it is in negligible quantities. In this sense, it cannot bring cholesterol into our body in large excess.

It remains to consider the effect of vegetable oils on blood cholesterol levels. After all, the oil may contain components that have a positive or negative effect on complex processes in the body in which cholesterol is involved, and indirectly affect the situation. For this purpose, you should familiarize yourself with the composition and properties of the product.

Beneficial properties of sunflower oil

Sunflower oil is 99.9% fat. Fatty acids are essential for our body. They improve mental activity and promote energy accumulation.

Unsaturated vegetable fats are considered the most beneficial. But for normal life, a 7/3 proportion should be observed between animal (saturated) and vegetable fats.

Some vegetable oils contain saturated fatty acids, such as palm oil and coconut oil. There are monounsaturated and polyunsaturated fatty acids. Monounsaturated fatty acids are found in olive oil. The source of polyunsaturated fatty acids are oils: corn, flaxseed, rapeseed, as well as cottonseed, sunflower, and soybean.

Sunflower oil contains:

• Essential polyunsaturated fatty acids: linoleic, linolenic. They have the property of removing bad cholesterol by creating a complex compound with it, thereby cleansing the blood vessels. Can be considered as a preventative against cardiovascular diseases, helping to reduce blood cholesterol levels.
• Vitamins A, D and E. Vitamin A improves vision and has a positive effect on the retina. Vitamin D is essential for maintaining good skin condition and normal functioning of the musculoskeletal system. Vitamin E is called the vitamin of “youth”, as it resists the processes of aging and the formation of tumors. It is also responsible for the production of hormones and the functioning of the reproductive system.

  

The influence of the production method on the composition of the oil

The technology for producing vegetable oil can radically change its beneficial properties and almost completely deprive it of its biological value.

Obtaining vegetable oil involves going through several stages:

• Squeeze or extraction. These are two different ways to complete the first stage. The spin can be cold or hot. Cold pressed oil is considered the healthiest, but does not have a long shelf life. Extraction involves extracting oil using solvents, which gives a greater yield of the finished product.
• Filtration. Crude oil is obtained.
• Hydration and neutralization. Treated with hot water. Unrefined oil is obtained. The value of the product is lower than that of raw oil, but the shelf life is longer - up to two months.
• Refining. A transparent product is obtained, devoid of color, odor, aroma and taste. Refined oil is the least valuable, but has a long (4 months) shelf life.

When choosing sunflower oil, you should pay attention to the sediment that is formed due to the high tendency to oxidize unsaturated fatty acids. But even if such sediment is not observed, it is important to make sure that it corresponds to the expiration date. Sunflower oil should be stored in a cool, dark place, on the wall of the refrigerator, for example.

Sunflower oil and cholesterol

In the fight against bad cholesterol, vegetable oils, including sunflower oil, are necessary helpers. Harm can only occur when using fried foods.

The following points cast doubt on the benefits of sunflower oil:

• Under the influence of high temperatures during frying, vitamins are decomposed, for which we actually eat it;
• Oil cannot be used repeatedly for frying due to the production of carcinogens. They cause harm and provoke the development of stomach cancer.
• During frying, food becomes more nutritious. It is known that overweight people usually suffer from excess cholesterol;
• If you do deep fry your French fries, opt for palm oil or coconut oil. These oils contain saturated fatty acids, are more stable and are better suited for deep frying. Olive or sunflower oils are best used when preparing dishes that are fried in a small amount of oil at medium temperature;
• Of course, transgenic fats that are formed during prolonged heating at high temperatures are harmful. They have a distorted structure that is not typical of natural products. Being integrated into cells, they contribute to metabolic disorders, accumulation of toxins and lead to atherosclerosis and severe consequences of heart disease. Most transgenic fats are found in margarine, which is a mixture of vegetable (palm) and animal fats. It should not be eaten.

However, vegetable oil is a product that can only indirectly affect cholesterol levels. If you have elevated blood cholesterol levels, you should not give up sunflower oil at all. You just have to reconsider your diet.

And it’s best to season vegetable salads with fresh, cold-pressed sunflower oil. And then the maximum benefits of its components and vitamins will manifest themselves in full!

Butter and cholesterol

One hundred grams of product contain:

• cholesterol – 215 mg (in ghee a quarter more: 270 mg);
• NLC – 52 g;
• MUFA – 21 g;
• PUFA – 3 g.

With its excessive consumption, a significant preponderance of saturated fats over unsaturated fats leads to an inevitable increase in cholesterol levels and low-density lipoproteins deposited on the walls of blood vessels.

Despite the fact that butter contains cholesterol, it is considered irrational to exclude it completely from the menu, keeping in mind the positive effects of saturated fats on the body. The minimum daily amount useful for a healthy person is 10 grams, the maximum allowable: for women – 20 grams, for men – 30 grams.

For high cholesterol, consume 5 g (teaspoon) per day, no more than 2-3 times a week.

Cholesterol and vegetable oil: benefits, harms

A few years ago, a commercial was shown on television that said that refined sunflower oil does not contain cholesterol, unlike unrefined sunflower oil. People believed in this and many still believe that there is cholesterol in unrefined vegetable oil. In fact, it's not there. Cholesterol is a fat of animal origin that cannot be found in products obtained from plants.

• Features of different types of fat

Composition of all vegetable oils

Any lean product contains a large number of useful elements, including palmitic, oleic, and linoleic acid. The composition also contains tocopherols and phosphorus-containing elements.

Despite the fact that the plant product consists of 100% fat, it should not be confused with cholesterol. All fats contained in lean foods are of plant origin. Therefore, they are better absorbed by the body, and, unlike fats of animal origin, they consist of monounsaturated and polyunsaturated acids. They are necessary for the human body for the normal functioning of cells, including the nervous system.

The plant product contains many vitamins. These are vitamin A, E, D, and other useful components. Each of them has its own effect on the body. Vitamin A strengthens the immune system and has a positive effect on vision. Vitamin E has a protective effect on the body, protecting against premature aging and cancer. Vitamin D is essential for bones and skin.

The relationship between cholesterol and oil

Seeing an advertisement on a label that says that a product does not contain cholesterol, people begin to involuntarily think that vegetable oils contain it. And with the next purchase, they begin to look at whether there is cholesterol in sunflower oil, why is its presence not indicated?

There is no cholesterol in vegetable oil and cannot be. The product is obtained from plants, they cannot contain cholesterol - fat of animal origin, but butter contains this substance, and in large quantities.

Lean foods contain monounsaturated fats, which help lower cholesterol. Therefore, they are prescribed to people with high cholesterol.

Types of vegetable oils

There is a wide range of different vegetable oils that people eat. They all have slightly different composition and properties.

Types and useful components of oils:

What's the benefit?

Vegetable oil is a beneficial substance. It contains many elements necessary for the normal functioning of the body. The benefits of the product are as follows:

1. Prevention of vitamin D deficiency in children.
2. Skin healing.
3. Using the product helps improve the body's immune defense.
4. Reduces the risk of cancer.
5. Reduces cholesterol.
6. Improves the function of the cardiovascular system (cardiovascular system).
7. Increases brain activity.

All types of vegetable oils have these beneficial properties.

Is there any harm?

The product may be hazardous to human health. When oil is heated, some useful elements disintegrate, and some form dangerous compounds. For this reason, nutritionists do not recommend eating foods fried in vegetable oil.

After boiling, a large amount of carcinogens that can cause cancer are formed in the product. Meat fried in oil is considered the most dangerous.

Recommendations for use

You need to eat cholesterol-free sunflower oil, that is, without animal fat, but with vegetables. The main thing is to use it in a regulated manner, since the product contains almost nine hundred calories per hundred grams.

Correct use of the product requires the following:

• Use strictly before the date indicated on the package. Using an expired product may cause metabolic problems due to accumulated oxides.
• Follow storage rules. Unrefined is stored at temperatures up to twenty degrees in a dark glass container, avoiding contact with water. A cold-pressed product can be stored for up to five months, and a hot-pressed product can be stored for about a year. However, once the bottle is opened, the contents should be consumed within a month.

It is healthy to eat any cholesterol-free vegetable oil. However, you can’t eat just one type; it’s best to combine several varieties. This will help saturate the body with different types of fats - monounsaturated, polyunsaturated and polyunsaturated. At the same time, foods containing polyunsaturated fats should be consumed in limited quantities, as they can lower HDL (high-density lipoprotein), which is responsible for lowering cholesterol levels. For example, you can mix corn, sunflower, and mustard oil in equal proportions.

The use of oils in the treatment and prevention of hypercholesterolemia

To reduce blood cholesterol levels with hypercholesterolemia, you need to change your diet. Saturated fats of animal origin increase cholesterol levels, while polyunsaturated and monounsaturated fats reduce them.

Sources of fats:

Saturated fats contain large amounts of cholesterol, which can cause cholesterol plaques in blood vessels.

Prevention of hypercholesterolemia involves reducing the consumption of saturated fats. It is worth understanding that they cannot be completely removed from the diet, since many cells of the body are built on the basis of animal fat. Therefore, you should reduce your consumption of saturated fats, but you cannot completely remove them from the menu.

Features of different types of fat

Different types of fats have their own characteristics. All of them are beneficial for the body, but must be used according to strict rules. After conducting different types of analyses, scientists came to the following conclusions:

1. Consumption of any type of fat should be moderate. Excessive consumption of fatty meats increases cholesterol levels in the blood.
2. Saturated substances can increase cholesterol levels.
3. Products of plant origin do not contain cholesterol.
4. Monounsaturated fats lower cholesterol levels.
5. Polyunsaturated fats lower cholesterol levels.
6. Cholesterol is found only in products of animal origin.

It is most beneficial to consume any types of vegetable oils not as monoproducts, but in mixtures consisting of several types of oils. This way the body will receive a large amount of a wide variety of vitamins, amino acids, and various types of vegetable fats. The latter will help cleanse the blood vessels and prevent complications such as hypercholesterolemia, atherosclerosis and other pathologies of the vascular system.

To summarize: table of oils that lower and increase cholesterol

Oils consumed in food can both increase cholesterol levels and reduce their levels: it all depends on the properties of the fatty acids that make up their basis.

We have collected all the edible oils that affect blood cholesterol levels in a final table.

Cholesterol content in vegetable and palm oils

Sunflower oil, like all other natural fats, does not contain cholesterol; reasonable consumption of many of them can normalize increased levels of atherogenic (deposited on the walls of blood vessels) fractions of lipoproteins.

In sunflower

Its percentage composition is presented:

Monounsaturated fats have a beneficial effect on lipid metabolism, reducing the production of low-density lipoproteins by the liver and accelerating their excretion through the intestines.

The small (compared to other liquid vegetable fats) amount of omega-3 is compensated in sunflower oil by a high content of phytosterols, which effectively reduce cholesterol levels by suppressing its absorption in the intestines.

Olive

One hundred grams of product contain:

• NJK – 14 g;
• MUFA – 73 g;
• PUFA – 11 gr.

According to studies, consuming olive oil with elevated levels of low-density lipoprotein reduces them by 3.5%.

Provencal oil is rich in polyphenols, which stimulate the production of “good” high-density lipoproteins, which prevent the attachment of atherosclerotic plaques - almost doubling their rate.

Its main value is the ratio of omega-3 and omega-6 essential fatty acids contained, which is close to ideal.

Linen

One hundred grams contain:

• NJK – 9 g;
• MUFA – 18 g;
• PUFA – 68 g, of which: 53.3% α-linolenic ω-3 and 14.3% linoleic ω-6.

Flax oil is a leader among vegetable fats in terms of its omega-3 content, which effectively reduces cholesterol levels by reducing its synthesis and accelerating its utilization.

They optimize lipid metabolism, improve the elasticity of blood vessels and blood fluidity, and restore liver function.

Corn

One hundred grams of product contain:

• NJK – 13 g;
• MUFA – 28 g;
• PUFAs – 55 g, represented by linoleic ω-6 acid;
• phytosterols - their amount corresponds to 1432% of the daily value.

Research shows that corn oil effectively lowers low-density lipoproteins by 10.9% and total cholesterol levels by 8.2%. Such an effective result is due to the combined effect of phytosterols and polyunsaturated fatty acids on the body.

Coconut

One hundred grams contain:
Despite the absence of cholesterol, a record amount of saturated fat in coconut oil provokes, when consumed, an increase in the amount of low-density lipoproteins circulating in the blood and deposited on the walls of blood vessels, forming atherosclerotic plaques.

Correct usage

To get a pronounced hypocholesterolemic effect from consuming vegetable oils, several points must be taken into account.

1. To reduce the level of atherogenic lipoproteins, only unrefined natural cold-pressed oils are used, which retain beneficial fatty acids, lecithin, phytosterols and flavonoids.
2. The norm for consuming vegetable fats for a healthy person is 20-30 grams (three tablespoons) per day. To avoid unpleasant side effects, the daily amount is divided into several doses.
3. The ratio of vegetable and animal fats in the diet is recommended to be 1.5 to 1, respectively; do not mix them at one meal, so as not to interfere with the absorption of natural oil.
4. It is recommended to adhere to the ratio of polyunsaturated fatty acids in the proportion of omega-3 to omega-6 as 1:10 (ideally 1:5).

5. 
   The product is used to season already prepared dishes: during heat treatment of unrefined oils, not only up to 40% of unsaturated fats are lost, but they are also transformed with the formation of toxic carcinogenic compounds.

6. Experts recommend not stopping at one type of vegetable fat, but alternating them periodically.
7. Store natural vegetable fats in the refrigerator, in tightly sealed dark glass bottles and strictly in accordance with the expiration date.

Compliance with these rules allows you to reveal all the positive properties of vegetable oils, reduce cholesterol levels and improve the health of the entire body.

The influence of the production method on the composition of the oil

The technology for producing vegetable oil can radically change its beneficial properties and almost completely deprive it of its biological value.

Obtaining vegetable oil involves going through several stages:

• Squeeze or extraction. These are two different ways to complete the first stage. The spin can be cold or hot. Cold pressed oil is considered the healthiest, but does not have a long shelf life. Extraction involves extracting oil using solvents, which gives a greater yield of the finished product.
• Filtration. Crude oil is obtained.
• Hydration and neutralization. Treated with hot water. Unrefined oil is obtained. The value of the product is lower than that of raw oil, but the shelf life is longer - up to two months.
• Refining. A transparent product is obtained, devoid of color, odor, aroma and taste. Refined oil is the least valuable, but has a long (4 months) shelf life.

Possible harm and contraindications

Cholesterol-free, unrefined natural oils are saturated with biologically active substances that can act as triggers for allergies and inflammation. They are high in calories - 899 kcal per hundred grams, and contain small amounts of saturated fat. Therefore, excessive consumption can lead to weight gain.

A long-term significant preponderance of omega-6 PUFAs over omega-3 in food - more than 15:1 - contributes to increased blood viscosity, the development of heart and brain ischemia, decreased immunity, and the risk of neoplasms increases.

Unrefined vegetable oils are not introduced into the diet of children under two years of age; complementary feeding begins gradually, starting with half a teaspoon per day and monitoring the child’s condition.

Caution when consuming unrefined natural fats is exercised when:

• low blood pressure;
• diabetes mellitus type II;
• biliary lithiasis;
• biliary dyskinesias;
• diarrhea;
• severe liver diseases.

The presence of these pathologies is not a contraindication to the use of unrefined vegetable fats; it is only recommended to reduce the consumed amount to half or a third of the daily amount: 1-1 ½ tbsp.

The benefits and harms of different types of vegetable oils

The benefits of any product are assessed by the ratio of substances necessary for the body and harmful. From this point of view, almost all vegetable oils are healthy: they contain few saturated fatty acids and many unsaturated and polyunsaturated ones. The exceptions are coconut and palm, and cholesterol has nothing to do with it: they are overloaded with saturated fats.

Sunflower, corn and olive oils are the main suppliers of polyunsaturated and unsaturated acids, since the taste allows them to be added to dishes in sufficient quantities. Their regular use helps improve brain function, normalize intestinal motility, strengthen the heart muscle and vascular walls, cleanse the skin, and get rid of bad cholesterol. Their role has also been proven in accelerating metabolism, preventing osteoporosis, improving visual acuity and coordination of movements. And with proper use of olive oil, the risk of developing breast cancer is also reduced.

Mustard oil, although not actually bitter, has a noticeable antiseptic and bactericidal effect. Sesame, in addition to unsaturated fat, contains phosphorus and calcium - the main microelements of bone tissue. Soybean and rapeseed (canola) are leaders in the fight against high cholesterol. The medicinal properties of sea buckthorn and flaxseed oils are more used in the manufacture of topical medicines for dermatological and gastroenterological patients.

Nut oils have a specific taste and are used in small quantities, although their qualities are not inferior to other vegetable fats. They lower cholesterol levels and also thin the blood, preventing thrombosis.

Effect of margarine on the body

One hundred grams of margarine produced in accordance with GOST are represented by:

• NJK – 15 g;
• MUFA – 39 g;
• PUFA – 24 g;
• trans fats – 15 gr.

Margarine does not contain cholesterol. In addition to animal, vegetable (including palm), saturated and unsaturated fats, it contains trans fats formed during the hydrogenation process. The harder the consistency of margarine, the more trans fats it contains. Trans fats are found not only in margarine: they can also be found in animal fats - up to 10%.

Trans isomers of fatty acids increase the level of low-density lipoproteins and triglycerides, while suppressing the formation of high-density lipoproteins. Trans fats not only increase the risk of heart and vascular diseases, but also disrupt the body's hormonal balance and cause enzymatic disorders.

Thus, when purchasing margarine, the choice is made in favor of soft varieties. If it is impossible to refuse this product, consume it in an amount not exceeding ½-1 tbsp. 1-2 times a week.

Healing properties

Ghee contains many valuable fatty acids

Ghee has many beneficial properties, but only if it is natural. The product is allowed to be eaten even by people who suffer from an allergic reaction to dairy foods and individual lactose intolerance. After all, during the processing process, the main milk components disappear, lactose and casein are absent.

Ghee contains many valuable fatty acids. One of them is butyric acid, which has a healing effect on the body, suppressing inflammation, preventing the development of cancer, normalizing the functioning of the digestive organs and supporting the activity of the heart and blood vessels.

The baked product also contains a large amount of vitamins A, D, E. Vitamin A is important for people who suffer from gluten intolerance, intestinal irritation, and pancreatic diseases.

A person receives vitamin D only when exposed to the sun, so the human body often lacks it. Vitamin E has a pronounced antioxidant effect and normalizes hormonal levels.

Ghee also produces the following effects:

• Normalizes the metabolism of substances in the body.
• Provides energy.
• Prevents the development of rickets and osteoporosis.
• Improves visual acuity.
• Improves brain activity.
• Prevents calcium deficiency in the body.
• Serves as a prevention of helminth infection.

It is also recommended to consume ghee for women carrying and breastfeeding a child. The product helps with the following:

• Helps build baby's bones.
• Prevents the development of anemia.
• Improves the quality of mother's milk.
• Reduces the risk of allergies in a child.
• Provides the mother and baby with calcium.

Attention! The benefits of ghee for human health are great. But to obtain it, you should give preference exclusively to natural oil. It is better if it is prepared at home.

What is ghee and what is it made from?

First of all, it is a product of animal origin. It is obtained as a result of heat treatment of butter. After the natural evaporation of water and various impurities, it acquires a number of positive characteristics.

This type of oil is quite popular in our country, in Central Asia, India and Pakistan. And the scope of its use is not limited only to cooking: it is widely used in medicine and cosmetology.

Interesting fact: in India it is called “ghee”, and it is widely used in Ayurveda, Indian traditional medicine. Indians attribute rejuvenating and healing properties to this product. The finished product differs from what we are used to with more caramelization and a nutty flavor. Local healers believe that the longer this “liquid gold” matures, the wider its miraculous properties become.

According to Russian GOST, the rendered product must contain 99% fat and no more than 1% water.

With this composition, the oil is stored much longer: about 8-9 months, and it can be heated up to 200 degrees. At the same time, unlike cream, it does not form a characteristic smoke and odor, and also does not provoke the appearance of carcinogenic substances in food.
