Olive oil contains 77% unsaturated fat and no cholesterol. Olive oil contains 77% unsaturated fat and no cholesterol.

Olive oil is gluten-free-it is found in wheat and rye, a little in barley and oats, but not in 100% pure olive oil.

Olive oil contains no salt.

Olive oil can make some healthy foods more delicious and can be used as their nutritional supplement. Such as fresh vegetables, fruits, noodles, coarse grains and other coarse grains, or seafood, poultry and so on.

Olive oil is suitable for mixing with other condiments, and olive oil can be used instead of salt in cooking.

Because olive oil is delicious, you don't need to put a lot of spices when cooking many dishes. Almost all edible oils contain about 120 calories per tablespoon, but they are also used for cooking and seasoning. The amount of olive oil is less than other vegetable oils.

Every tablespoon (14g) of olive oil contains 1.6 mg, or 2.3IU of vitamin E (a natural antioxidant).

1 tablespoon provides 8% of vitamin E in RDA.

Olive oil can be used as a substitute for butter and margarine in the cooking process of many dishes.

When there is no scientific research on olive oil, there is a paper in the journal of American Medical Association that the unsaturated fatty acids rich in olive oil can reduce the cholesterol content in blood.

First, eat more olive oil and stay away from breast cancer.

A recent study by American scientists proved that a fatty acid in olive oil can prevent the growth of protein, thus promoting the spread of breast cancer cells, thus reducing the risk of breast cancer in women.

The fatty acid with anticancer effect in olive oil is called oleic acid.

The latest issue of New Scientist, published on June 5438+05, reported that scientists from Northwestern University in the United States adopted a different approach in their research. they

The different components of olive oil were tested respectively. In the study, they dripped oleic acid rich in olive oil into the breast cancer cell culture medium, so that the proportion of oleic acid in the culture medium was equal to that in the blood of people who often ate olive oil. They found that oleic acid reduced the production of Her2/neu protein by half, which is a key substance to promote the growth of breast cancer cells.

Second, use olive oil as a skin care product.

The skin care products chosen in winter are mainly creams. However, the skin is still very dry. If using cream skin care products still doesn't help, try olive oil. Because vitamins A, D and E in olive oil have certain effects on wrinkles and skin allergies, of course, it is only suitable for dry skin.

Olive oil may be too greasy for ordinary dry skin, so the usage should be changed slightly. For example, when taking a bath, add DIY olive oil masks such as honey and lemon juice. After finishing the cleaning step, apply it to your face first and wash it off directly after taking a shower. In addition, skin care products containing vitamin E also have moisturizing effect and can be used more.

The latest research shows that olive oil helps to lower blood pressure.

Olive oil is good for blood. New research shows that olive oil can protect people from heart disease in several ways.

According to sufficient evidence, about two-thirds of strokes and half of the incidence of heart disease are caused by rising blood pressure. According to the latest report of the World Health Organization, hypertension can cause 7,654,380+deaths worldwide.

The food industry is facing the burden of increasing incidence of heart disease. In 2002, the value of food and drink produced in Britain for protecting heart health was 654.38+007 billion. According to the forecast of relevant departments, this figure will rise to 654.38+0.45 1 100 million pounds in 2007.

Fourth,

Olive oil, slimming and skin care.

Olive oil is a light yellow transparent liquid, rich in vitamins A, D, E, K and F, which are fat-soluble vitamins easily absorbed by the skin. Especially, the content of vitamin E per 100 g olive oil is 8 mg, which is the highest among all plants. Vitamin E can break down body fat and help secrete hormones. Therefore, olive oil is a good product for weight loss and beauty.

Olive oil diet

Olive oil contains vitamin E, which is easily absorbed by the skin, thus helping to keep women's body beautiful. When taking a bath, wash your body first, then dip cotton in olive oil and cover your whole body, then wrap it with a hot towel. 10 minutes later, rinse it with warm water.

Olive oil beauty method

Compared with other vegetable oils, olive oil has a higher viscosity. This viscosity makes the skin have a good suction and can prevent the skin from evaporation. Therefore, olive oil is the best skin care product whether facing the sun in summer or the cold wind in winter.

1. Make up. Ladies who often wear makeup must have experienced that it is not easy to put on makeup when they are too tired at work or lack of sleep. You can turn to olive oil at this time. The method is to drop 1 ~ 2 drops of olive oil into the basic cosmetics, rub it and apply it evenly to the face, and the skin will become bright and vivid immediately.

2. Apply a surface. Wash the oil off your face with warm water, gently wipe off the water with a dry towel, then dip cotton in olive oil and spread it all over your face. The more olive oil penetrates, the better the effect, so in order to increase the penetration of olive oil, gently massage your face with your hands. 10 ~ 15 minutes later, apply a hot towel to your face, and then gently wipe it with a dry towel.

Five, olive oil beauty oil

Olive oil is made from olive fruit by direct cold pressing and natural separation of oil and water. Its nutritional components are balanced and ideal, and it does not contain essence and any artificial chemicals. Its fatty acid composition and various natural fat-soluble vitamins are very beneficial to nourish the skin.

Stars like to massage their navel with olive oil. Elizabeth Taylor, Mary Monroe, Jenny Ward and other famous stars, the secret of bodybuilding is to use olive oil. They not only covered themselves with olive oil, but also massaged their navel with olive oil. A famous sculptor appointed his model to be painted with olive oil, because in this way, the posture of the model can show vivid beauty and the statue can be lifelike. Therefore, many fashion models have 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. Handsome guys all over the world boast that they are strong and use olive oil. When the baby was born, the nurse also washed the navel with olive oil, which shows that there is a medical basis.

Teresa Teng, a famous singer, seldom used nail polish before his death. She often massages her nails with olive oil to make them transparent and shiny, giving off a healthy luster.

Sophia Loren bathed in olive oil. After many years, sophia loren is still so beautiful and charming. Although sophia loren pays great attention to clothes, she doesn't hide her age. She said: "It takes time and iron discipline to be beautiful." The big star has strict rules of daily life. He goes to bed at 22 o'clock and gets up at 6 o'clock every day. He never drinks or smokes. After doing gymnastics for 40 minutes, he began to do indoor activities. She likes to put olive oil in bath water to keep her skin moist and elastic.

Six, olive oil and cancer

[AFP, Paris, 65438+20001October 24th] Researchers from the hermanns Trias Puyol Medical College in Barcelona reported their research results in the special issue of the British medical journal Intestines.

*** 108 mice were divided into several groups on average, and each group was fed with food rich in safflower oil, fish oil or olive oil. Rats in each group were divided into two parts, and half were fed carcinogens. After feeding mice 19 weeks, the researchers dissected the mice. They want to see if there are tumors or tumor precursors in the intestines of mice. Mice fed with food rich in safflower oil have more precancerous tissues, such as intestinal polyps, than mice fed with food containing fish oil or olive oil. Their blood concentration of arachidonic acid is very high. Arachidonic acid is a major carcinogen.

The researchers said that this is the first laboratory study on the characteristics of olive oil. Olive oil contains different fatty acid molecules n9. Researchers believe that these functions of olive oil mainly come from squalene, flavonoids and polyphenols, which can protect cells from so-called free radicals-free radicals are some atomic groups that can destroy the health of cells and make them worse.

With the assistance of Harvard School of Public Health, a medical study in Greece showed that the incidence of breast cancer can be reduced by 25% for women who regularly eat olive oil.

Torrison Pruss, a professor at Harvard University who participated in the survey, pointed out: "Animal experiments show that eating olive oil may not increase the incidence of breast cancer caused by chemical factors like eating other types of fat. So we also hope to reach the same conclusion in humans.

Subjects included 820 newly diagnosed breast cancer patients and 1500 breast cancer patients in Greece. The incidence of breast cancer in women who eat olive oil at least twice a day is significantly reduced, the incidence can be reduced by 25%, and the recurrence rate can be controlled at 20 to 30%.

Experts believe that Mediterranean countries are the producing areas of olives. In the past, these areas have always had the habit of eating olive oil, and the incidence of breast cancer is less. In recent years, the incidence of breast cancer has increased because people turn to foods with high animal fat.

Pruss pointed out that studies have shown that there is a clear difference between eating a different fat and whether it can reduce the incidence of breast cancer. Doctors advise women to choose reasonable fat varieties and control their fat intake appropriately. Is the key to prevent breast cancer. In particular, there are indications that margarine has an adverse effect on the incidence of breast cancer.

Seven, olive oil and fried cooking

In order to make food more delicious, people use cooking methods such as boiling, barbecue, smoking and frying. When frying food, you need to reach a very high temperature.

When the temperature is transferred to the inside of the food by frying, the temperature should be kept almost at 100℃ until the water in the food is evaporated. At this temperature, hot oil begins to boil, which means that oil can act on food in a short time without the harm of other cooking methods. Hard crust is formed on the outside of bread, which is the result of hot oil. Hot oil can make protein coagulate well and turn carbohydrates into caramel.

Fat can self-oxidize, and this oxidation is accelerated with the increase of temperature. This phenomenon is caused by a certain degree of unsaturation and the existence of oxygen-loving substances, and antioxidant substances can inhibit this phenomenon. Some spoiled things are volatile and easy to be removed: others (polymers) are difficult to be absorbed, and some are toxic, which will affect various organs of the human body and reduce the nutritional value of food.

Animal fats are low in unsaturation and contain no antioxidants, so automatic oxidation is likely to occur. Seed oil is extremely unsaturated and easily oxidized. Contrary to the above two, olive oil is very stable because of its moderate unsaturation and antioxidant substances. Food deterioration is not only affected by the types of fats, but also related to temperature, heating time, food types and whether catalysts are used.

The stability of olive oil at extremely high frying temperature and the digestibility of food will not change because of frying in olive oil, even if the meat or sardines are fried with the same olive oil for more than 10 times. This study seems to show that olive oil is the most suitable oil for frying, because it is more resistant to deterioration caused by oxidation.

Eight, olive oil and arteriosclerosis

Atherosclerosis is one of the most common diseases in industrialized countries, and it is also one of the diseases leading to death. In addition to genetic factors, there are other risk factors that can lead to the appearance or deterioration of the disease: smoking, hypertension and hypercholesterolemia. Other factors include age, sex (male), diabetes, gout, high triglyceride index, oral contraceptives and lack of exercise.

Cholesterol belongs to sterol, which is an ester that exists in large quantities in animals. It is insoluble in water but soluble in organic solvents. It forms a part of cell membrane, and in many cases, it can form stable compounds with phospholipids. In human body, cholesterol, as the main component needed to synthesize other steroids, participates in important processes such as bile acid formation. Bile acids can emulsify the fat in food and make it absorbed by intestinal epithelium by vitamin regulation mechanism.

The occurrence of atherosclerosis is closely related to eating habits. A diet rich in animal fat helps to raise cholesterol levels. On the other hand, vegetable oil rich in polyunsaturated fatty acids has a protective effect against atherosclerosis and can reduce the cholesterol index in human body.

It has been proved that not all cholesterol has atherosclerosis gene. The cholesterol transported by low-density lipoprotein (LDL) is like this, while the cholesterol transported by high-density lipoprotein (HDL) seems to have a protective effect, because the function of high-density lipoprotein is to clear free cholesterol in cells and transport it to the liver, where cholesterol is decomposed by bile.

Many studies have confirmed the negative adjoint relationship between low density lipoprotein index and atherosclerosis and the positive adjoint relationship between high density lipoprotein and longer life expectancy.

Any treatment of hypercholesterolemia must start with reducing the intake of saturated fatty acids. Inhibition of these fats can reduce cholesterol twice as much as that obtained from the same amount of polyunsaturated lipids. If olive oil rich in monounsaturated substances is used as a substitute, the whole cholesterol index will be roughly close to the result of reducing saturated fat intake. This positive effect of monounsaturated fat will not only be similar to the substitution effect of polyunsaturated fat. It can also increase high-density lipoprotein cholesterol and help reduce the mortality of coronary heart disease. A comparative study of 10000 men who died of coronary heart disease shows that Americans and French people have roughly the same risk of developing such diseases under the same cholesterol index, but for people living in the Mediterranean, the risk is greatly reduced because olive oil accounts for a high proportion of all kinds of fats consumed by the latter.

When excessive intake of vegetable oil rich in polyunsaturated substances, it is easy to produce peroxidation. For this reason, this oil will become an atherosclerosis gene, which may also be the cause of endothelial disease and extreme platelet aggregation.

At present, it is concluded that the most important step to prevent atherosclerosis is to reduce animal fat-visible and invisible-and replace it with olive oil rich in monounsaturated substances. Although olive oil also contains balanced polyunsaturated substances, these polyunsaturated substances are properly protected by antioxidant substances such as α -tocopherol or polyphenols. This eating habit, which is recognized by experimental and epidemiological research results, will provide a certain guarantee for disease prevention and satisfactory cholesterol control, and reduce the risk of negative effects.

Nine, olive oil and longevity

From the beginning, food provided energy for human growth and life. Every year, cells inherit the genes that determine their physiological activities and copy them countless times. However, errors will occur during continuous replication. At first, these mistakes can be corrected, but after many times, these mistakes will accumulate and other mistakes will form an incorrect message. Foods rich in polyunsaturated fatty acids can lead to peroxidation, which puts cells at risk of the above mistakes. On the other hand, the existence of antioxidant substances such as vitamin E provides a defense mechanism for human beings. Mice that ate olive oil lived longer than those that ate sunflower oil and corn oil. This phenomenon can be explained by the optimal ratio of vitamin E and polyunsaturated substances in olive oil. When this experiment is applied to the human body, the results of the study remind people not to eat oils rich in polyunsaturated substances indiscriminately, but to choose olive oil when ingesting various edible fats, because linoleic acid, linolenic acid, antioxidants and other components in olive oil are very balanced.

In the study of skin changes, PINKEY's report pointed out that people who regularly eat foods with polyunsaturated substances content exceeding 10% will show signs of aging. In 60% cases, the skin is removed because of illness, because these lesions are suspected to be malignant.

Bone calcification was once a common disease. Olive oil seems to have a positive effect on preventing this disease. It depends on the intake, because the more olive oil you consume, the better the mineralization of bones. The explanation can be found from the fact that there are a large number of oleates in the constituent lipids of bones. According to the research results of French researchers, olive oil may be necessary for people from growth to adulthood, which can prevent the loss of calcium.

In old age, people's digestive ability will decline, and their absorption of nutrients, especially vitamins and minerals, will become poor. Olive oil also has excellent characteristics in digestion and absorption, and has a mild laxative effect. Whether frying or cooking olive oil, it is best to keep vitamins and antioxidants from being destroyed to the maximum extent, and it is best to eat them raw. Olive oil can also make food more tasty and easier to absorb.

Ten, olive oil and childhood

For newborns and babies, fat intake is extremely important. The intake of essential fatty acids is more important. Breast-fed babies can absorb 4-5% calories from fat in the form of polyunsaturated fatty acids, while milk-fed babies absorb even less calories. Low intake of linoleic acid will delay people's growth and development and cause diseases in skin, liver and metabolism. It is not recommended for children to take a large amount of seed oil rich in polyunsaturated substances, because the cholesterol content of this oil is too high, and this oil will accelerate the oxidation phenomenon, especially for children with low vitamin E reserves. Therefore, it is very important to strictly keep the balance between linoleic acid and linolenic acid in the diet, because too high a proportion will cause nervous system diseases. Foreign olive oil research centers have done a comparative experiment, which is to feed growing mice with olive oil, sunflower oil and saturated fat, and compare the effects. Gary found that in several groups of experiments using saturated fat and sunflower oil, the lipid compounds in the brain and liver of mice changed. However, this phenomenon did not appear in the experimental group of olive oil. Olive oil provides a relatively small amount of fatty acids, and the ratio of linoleic acid to linolenic acid is balanced, which is very similar to that found in breast milk.

In terms of the effect of olive oil on bone mineralization and development, it has been proved that it is necessary to ingest fat. The best effect can be obtained by ingesting oleic glycerol containing very little polyunsaturated fatty acids. Therefore, in order to achieve this goal, the best way is to eat those foods containing olive oil.

Eleven, olive oil and stomach

Authoritative data show that olive oil is the most easily absorbed oil in the stomach because it contains a lot of oleic acid.

Sphincters separate stomach organs from esophagus, preventing the backflow of gas-containing juice, and are hardly affected by olive oil. Butter is a kind of fat that is not easily absorbed by human body, while sunflower seed oil is easily absorbed, ranking between olive oil and butter. The emptying time of the stomach is also affected by these two fats.

Since ancient times, people have described that olive oil has a good curative effect and protective effect on gastritis and gastric ulcer. Patients with gastric ulcer use olive oil instead of animal fat in their food. As a result, the damage of fat to the stomach will be reduced by 33% and the cure rate will reach 55%. However, the prescription of olive oil prescribed by doctors does not rule out the possibility of treatment with other drugs.
