What are the benefits of olive oil?
Olive oil contains 77% unsaturated fat and has no cholesterol. Olive oil contains 77% unsaturated fat and has no cholesterol.
Olive oil does not contain gluten - it can be found in wheat, rye, and also in small amounts in barley and oats, but it is not found in 100% pure olive oil.
Olive oil contains no salt.
Olive oil can make some healthy foods more delicious and serve as a nutritional supplement to them. Such as: fresh vegetables, fruits, noodles, whole grains such as cereals and rice, or seafood and poultry meat, etc.
Olive oil is suitable for mixing with other condiments and can be used instead of salt in the preparation of dishes.
Because olive oil is so delicious, you don’t need to add a lot of seasonings when cooking many dishes. Nearly all cooking oils contain similar calories per tablespoon—about 120 calories—but for cooking and seasoning, olive oil is used in smaller amounts than other vegetable oils.
Each tablespoon (14g) of olive oil contains 1.6mg, or 2.3IU (international units) of vitamin E (a natural antioxidant).
One tablespoon of vitamin E provides 8% of the RDA (recommended daily allowance).
Olive oil can be used as a substitute for butter and margarine in many dishes.
When there was no scientific research on olive oil, there was a paper in the Journal of the American Medical Association stating that the unsaturated fatty acids rich in olive oil can reduce blood cholesterol levels.

1. Eat more olive oil to stay away from breast cancer
A recent study by American scientists proved that a fatty acid in olive oil can stop the growth of a protein that promotes the spread of breast cancer cells, thereby reducing women's risk of breast cancer.
The fatty acid in olive oil that plays an anti-cancer role is called oleic acid.
The latest issue of the British "New Scientist" magazine published on the 15th reported that scientists from Northwestern University in the United States adopted a different approach from the past in their research. They
examined olive oil. The different ingredients were tested separately. In the study, they dropped oleic acid, which is rich in olive oil, into breast cancer cell culture fluid, and made the ratio of oleic acid in the culture fluid equivalent to that in the blood of people who regularly consume olive oil. They found that oleic acid cut in half the production of Her2/neu, a protein that is key to promoting the growth of breast cancer cells. Excerpted from Xinhuanet, January 15th

2. Use olive oil as skin care products
The skin care products you choose in winter are mainly creams. However, if your skin is still very dry and cream-based skin care products still don’t help, you can try olive oil because of the vitamins A, D, and vitamins in olive oil. E has certain effects on wrinkles and skin allergies. Of course, it is only suitable for dry skin.
For ordinary dry skin, olive oil may be too greasy, so the usage needs to be changed. While you are taking a shower, add honey, lemon juice, etc. to DIY an olive oil mask. After completing the cleaning steps, apply it on your face and wash it off directly after taking a shower. In addition, skin care products containing vitamin E also have a moisturizing effect. , can be used in many ways.
3. Latest research shows that olive oil can help lower blood pressure
Olive oil is good for the blood. New research shows that olive oil can protect people from immunity in several ways. Sufficient evidence shows that approximately 2/3 of strokes and half of heart disease are caused by elevated blood pressure. According to reports, high blood pressure can kill 7.1 million people worldwide.
The food industry is facing the burden of increasing incidences of heart disease.
In 2002, in the UK alone, the production of heart-healthy foods and beverages was worth 100.7 million pounds. According to relevant department predictions, this value will rise to 145.1 million pounds in 2007

Olive oil, both slimming and skin care
Olive oil is a light yellow transparent liquid, rich in vitamins A, D, E, K, F, which are easily Fat-soluble vitamins absorbed through the skin. Especially the content of vitamin E, which is 8 mg per 100 grams of olive oil, is the highest among all plants. Vitamin E can break down fat in the body and help secrete hormones. Therefore, olive oil is a good product for weight loss and beauty.
Olive oil weight loss method
Olive oil contains vitamin E, which is easily absorbed by the skin, thus helping to maintain a beautiful body for women. When bathing, first wash the body, then soak cotton with olive oil and apply it all over the body, then wrap it in a hot towel, and rinse with warm water after 10 minutes.
Olive oil beauty method
Compared with other vegetable oils, olive oil has a stronger viscosity. This viscosity provides good adsorption to the skin and prevents skin moisture from evaporating. Therefore, whether facing the sun in summer or the cold wind in winter, olive oil is the best skin care product.
1. Put on makeup. Women who often wear makeup must have this experience: it is not easy to put on makeup when they are too tired from work or lack sleep. At this point, you can turn to olive oil. The method is to add 1 to 2 drops of olive oil to basic cosmetics, rub it in and apply it evenly on the face, and the skin will immediately become bright and vivid.
2. Apply to the face. First wash off the oil on your face with warm water, gently wipe away the water with a dry towel, then dip cotton in olive oil and apply it all over your face. The more olive oil penetrates, the better the effect, so use your hands to gently massage your face to increase the penetration of olive oil. After 10 to 15 minutes, apply a hot towel to the face, and finally wipe it gently with a dry towel.
5. Olive oil beauty oil
Olive oil is directly cold-pressed from the olive fruit, and the oil and water are naturally separated and then refined. The nutritional content is balanced and ideal, and it does not contain flavors and any artificial Chemical substances, its fatty acid composition and a variety of natural fat-soluble vitamins are very beneficial to nourishing the skin.
Celebrities like to use olive oil to massage their belly buttons. Elizabeth Taylor, Mary Monroe, Jenny Ward and other famous celebrities, the secret to bodybuilding is to use olive oil. Not only do they Apply olive oil all over your body and massage your navel with olive oil. There is a famous sculptor who specified that his model should be covered with olive oil, because in this way, the model's body can show vivid beauty and the statue can be lifelike. Therefore, many clothing models have also followed suit, hoping to improve their posture.
The navel is the center of the whole body, and the control center can control the whole body. The most handsome men in the world boast of their strong bodies, and they also use olive oil. When the baby is born, the nurse also washes the navel with olive oil. It can be seen that this has a medical basis.
The famous singer Teresa Teng rarely used nail polish during her lifetime. She often used olive oil to massage her nails to make them transparent and shiny, giving off a healthy luster.
Sophia Loren bathes in olive oil. After many years, Sophia Loren is still so beautiful and charming. Although Sophia Loren pays great attention to her clothes, she does not hide her age. She said: "To be beautiful, you need to spend time and have iron discipline." This big star has strict daily routines. She goes to bed at 22 o'clock every day and gets up at 6 o'clock in the morning. She does not drink alcohol and never smokes. After 40 minutes of gymnastics, indoor activities begin. She likes to add olive oil to the bath water to keep her skin moist and elastic.
6. Olive oil and cancer
[AFP, Paris, January 24, 2000] Hermans Trias Pujol School of Medicine, Barcelona, ??Spain The researchers report their findings in the BMJ Gut Special Issue.
A total of 108 mice were evenly divided into several groups, and each group was fed food rich in safflower oil, fish oil, or olive oil. The mice in each group were split in half, and one half was fed carcinogens. After feeding the mice for 19 weeks, the researchers dissected the mice. They wanted to see if there were tumors or precursors to tumors in the mice's intestines.
Mice fed a diet rich in safflower oil had more precancerous tissue, such as intestinal polyps, than mice fed a diet containing fish oil or olive oil. Their blood has high concentrations of arachidonic acid. Arachidonic acid is a major carcinogen.
Researchers say this is the first laboratory study of olive oil's properties. Olive oil contains a different fatty acid molecule, n9. Researchers believe that these functions of olive oil come mainly from components such as squalene, flavonoids and polyphenols, which protect cells from so-called free radicals------ Groups of atoms that destroy the health of cells and cause them to deteriorate.
A medical study conducted by the Harvard School of Public Health in the United States with assistance from Greece showed that women who regularly consume olive oil can reduce the incidence of breast cancer by 25%.
Professor Torison Preuss of Harvard University, who participated in this survey, pointed out: "Animal experiments have shown that consuming olive oil is not like consuming other types of fats, which may increase the risk of chemical factors. The incidence of breast cancer. So we also hope to draw the same conclusion in humans.
The study subjects included 820 new-onset and 1,500 breast cancer patients in Greece who ate olives at least twice a day. The incidence of breast cancer in women who consume oil is significantly reduced, the incidence rate can be reduced by 25%, and the recurrence rate is also controlled by 20 to 30%. Experts believe that countries along the Mediterranean Sea are the origin of olive oil. These areas have always had the habit of consuming olive oil, and the incidence of breast cancer is relatively low. In recent years, the incidence of breast cancer has increased due to people turning to foods high in animal fat.
Pruss pointed out that. Studies have shown that eating different types of fat is significantly different from reducing the incidence of breast cancer. Doctors advise women to choose reasonable fat types and properly control fat intake. In particular, there are indications that. , Margarine has adverse effects on the incidence of breast cancer
7. Olive oil and fried cooking
In order to make food more flavorful, people use methods such as boiling, grilling, and frying. Cooking methods such as smoking and frying need to reach very high temperatures when frying food.
When the temperature is transferred to the inside of the food through frying, the temperature must be maintained at almost 100°C until the food is fried. At this temperature, the hot oil begins to boil, which means that the oil can act on the food in a short time without the hazards of other cooking methods. It is the result of the action of hot oil, which can condense proteins and turn carbohydrates into caramel.
Fat can undergo auto-oxidation, which accelerates as the temperature increases. This phenomenon is caused by the presence of a certain degree of unsaturation and oxygen-loving substances, and antioxidant substances have an inhibitory effect on this phenomenon. Some things that deteriorate are volatile and easily removed: while others (polymers) are. It is difficult to absorb, and some of what remains can be toxic, affecting various organs of the body and reducing the nutritional value of food.
Animal fats have low unsaturation and contain no antioxidants. , and therefore prone to auto-oxidation. In contrast to the above two, seed oil is extremely unsaturated and easily oxidized, while olive oil is very stable due to its moderate degree of unsaturation and the antioxidants it contains. Substance. In addition to being affected by the type of fat, food deterioration is also related to temperature, heating time, type of food and whether to use a catalyst.
The stability and stability of olive oil at extremely high cooking temperatures. The digestibility of food does not change because it has been fried in olive oil, not even meat or sardines that have been fried in the same olive oil more than 10 times. The findings appear to suggest that olive oil is the best oil for frying because it is more resistant to spoilage caused by oxidation.
8. Olive oil and atherosclerosis
Atherosclerosis is one of the most common diseases in industrialized countries and one of the leading causes of death. In addition to genetic factors, there are other risk factors that can cause the lesions to appear or worsen: smoking, high blood pressure and hypercholesterolemia.
Additional contributing factors include age, gender (male), diabetes, gout, high levels of triglycerides, oral contraceptives and lack of exercise.
Cholesterol belongs to sterols, which is an ester abundant in animal bodies and insoluble in water but soluble in organic solvents. It forms part of the cell membrane and, in many cases, forms stable compounds with phospholipids. In the human body, cholesterol serves as the main component required for the synthesis of other steroids and participates in important processes such as bile acid formation. Bile acids can emulsify fats in food so that they can be absorbed by the intestinal epithelium through the modulation mechanism of vitamins.
The occurrence of atherosclerosis is closely related to dietary habits. A diet rich in animal fats can help improve cholesterol levels. On the other hand, vegetable oils rich in polyunsaturated fatty acids have a protective effect against atherosclerosis and can also reduce cholesterol levels in the body.
It has been confirmed that not all cholesterol is atherosclerotic. Cholesterol transported by low-density lipoproteins (LDL) does this, while cholesterol transported by high-density lipoproteins (HDL) appears to have a protective effect because HDL's role is to eliminate free cholesterol within cells and transport it to the liver, where cholesterol is broken down by bile.
Several studies have identified a negative concomitant relationship between LDL markers and atherosclerosis and a positive concomitant relationship between HDL and longer estimated lifespan.
Any treatment plan for hypercholesterolemia must begin with reducing the intake of saturated fatty acids. Inhibition of these fats reduces cholesterol twice as much as that obtained from equivalent amounts of polyunsaturated-rich lipids. If olive oil, which is rich in monounsaturated substances, is used as a substitute, the overall cholesterol level will be roughly close to that obtained by reducing the intake of saturated fat. This positive effect of monounsaturated fats is not limited to similar replacement effects as polyunsaturated fats. It also increases HDL cholesterol and helps reduce mortality from coronary heart disease. A comparative study of 10,000 (men) people who died from coronary heart disease showed that Americans and French people with the same cholesterol levels had roughly the same risk of developing the disease, while people living in the Mediterranean region had about the same risk. said, the risk is greatly reduced because olive oil accounts for a high proportion of the various fats consumed by the latter.
When vegetable oils rich in polyunsaturated substances are consumed in excess, peroxidation is likely to occur. Due to this, the oil will become atherogenic, which may also This is the cause of endothelial lesions and extreme platelet aggregation.
The conclusion reached so far is that the most important step in preventing atherosclerosis is to reduce animal fat - visible and invisible, and replace it with olive oil rich in monounsaturated substances . Although olive oil also contains a balance of polyunsaturates, these polyunsaturates are properly protected by antioxidants like alpha-tocopherol or polyphenols. This eating habit, which has been approved by experimental research results and epidemiological research results, will provide a certain guarantee for disease prevention and satisfactory control of cholesterol, and reduce the risk of negative effects.
9. Olive oil and longevity
Food has provided humans with the energy needed for growth and life from the beginning. Every year cells inherit the genetic genes that determine their physiological activities and replicate them countless times. However, the continuous copying process also makes errors. Initially these errors can be corrected, but after repeated occurrences, these errors accumulate and are combined with other errors to form an incorrect message. Foods rich in polyunsaturated fatty acids can lead to peroxidation, a phenomenon that puts cells at risk of making these mistakes. On the other hand, the presence of antioxidants such as vitamin E provides humans with a defense mechanism. Rats fed olive oil had longer estimated lifespans than those fed sunflower oil and corn oil. The above phenomenon can be explained by the fact that olive oil has the best ratio of vitamin E and polyunsaturated substances. When this experiment is applied to humans, the results remind people not to indiscriminately consume oils rich in polyunsaturated substances. When ingesting various types of edible fats, it is best to choose olive oil because olive oil contains sub-oils. The composition of acids, linolenic acids and antioxidants is well balanced.
In a study of skin changes, PINKEY reported that people who regularly consumed foods containing more than 10% polyunsaturated substances showed signs of aging. Sixty percent of cases resulted in diseased skin being removed because the lesions were suspected to be malignant.
Bone calcification used to be a common disease. Olive oil appears to have positive results in preventing this disease. This depends on the amount consumed, as the more olive oil you consume, the better your bones will be mineralized. The explanation can be found in the presence of large amounts of oleate in the lipids that make up bones. According to the findings of French researchers, olive oil may be necessary for people from growth and development to adulthood to prevent the loss of calcium.
In old age, people's digestive ability will decline, and the absorption of nutrients, especially vitamins and minerals, will become very poor. Olive oil also has excellent properties for digestion and absorption, and has mild laxative properties. Regardless of whether you consume olive oil by frying or cooking, you should maximize the vitamin and antioxidant content from being destroyed, and it is best to eat it raw. Olive oil also makes foods more flavorful and easier to absorb.
10. Olive oil and childhood
For newborns and infants, fat intake is extremely important. Getting essential fatty acids is even more important. Breastfeeding babies can absorb 4-5% of their energy (calories) from fat in the form of polyunsaturated fatty acids, while cow-fed babies can absorb even less. Too low linoleic acid intake can delay human growth and development and cause skin, liver and metabolic diseases. It is not recommended that children consume large amounts of seed oils rich in polyunsaturated substances, because firstly, the cholesterol content of this oil is too high, and secondly, this oil can accelerate oxidation, especially for those with low vitamin E reserves. child. Therefore, it is important to maintain a strict balance between linoleic acid and linolenic acid in the diet, because too high a ratio can cause neurological diseases. A foreign olive oil research center conducted a comparative experiment in which olive oil, sunflower oil and saturated fat were fed to growing white mice to compare the effects. Galli found that in several experiments with saturated fat and sunflower oil, lipid compounds in the brains and livers of rats were altered. However, in the set of experiments conducted with olive oil, there was not a single case of this phenomenon. Olive oil provides relatively low amounts of fatty acids and has a balanced linoleic to linolenic acid ratio that is very similar to that found in breast milk.
The necessity of fat intake has been demonstrated in terms of the effect of olive oil on the mineralization and development of bones. The best results can be achieved by taking glyceryl oleate, which has been added with a very small amount of polyunsaturated fatty acids. Therefore, the best way to achieve this is to consume foods that contain olive oil.
11. Olive oil and the stomach
According to authorities, olive oil is the easiest oil to be absorbed by the gastric organ because it contains a large amount of oleic acid.
The sphincter that separates the gastric organ from the esophagus and prevents the reflux of gas-containing juices is hardly affected in any way by olive oil. Butter is a fat that is not easily absorbed by the body, while sunflower oil is easier to absorb, ranking between olive oil and butter. Gastric emptying time is affected by both fats in the same way.
Since ancient times, olive oil has been described as having great curative and protective properties against gastritis and stomach ulcers. When patients with gastric ulcers replaced animal fat with olive oil in their food, the result was a 33% reduction in damage to the stomach caused by fat and a 55% cure rate. However, a doctor's prescription for olive oil does not exclude the possibility of treatment with other medications.
