Peanut oil has a strong fragrance and is one of the main edible oils in our daily life. Peanut oil can provide a lot of nutrition to human body, and it can also increase the delicacy of food. It is an important raw material for various tissue components of human body.
efficacy
Research by Chinese Academy of Preventive Medicine confirmed that the zinc content of peanut oil is 37 times that of salad oil, 32.6 times that of corn oil, 16 times that of rapeseed oil and 7 times that of soybean oil. Although there are many ways to supplement zinc, oil is a necessary supplement for people, so edible peanut oil is especially suitable for people to supplement zinc. Nutritionists also found that peanut oil contains three health-care components beneficial to cardiovascular and cerebrovascular diseases: resveratrol, rich monounsaturated fatty acids and β -sitosterol. Experiments show that these substances are chemopreventive agents for tumor diseases, reduce platelet aggregation, prevent and treat arteriosclerosis and cardiovascular and cerebrovascular diseases, and are one of the ideal edible oils for middle-aged and elderly people. High-quality peanut oil contains a variety of anti-aging ingredients, which has the effect of delaying the aging of brain function.

≮ Special tips ≯
Peanut oil is resistant to high temperature, and it is suitable for frying food except cooking. After all, it is high in calories and fat. Eating too much will still have a certain impact on cardiovascular and cerebrovascular diseases, and it is easy to get fat.
Peanut oil has high nutritional value.
Internationally, people have reached a consensus that peanuts are a very healthy food. As a result, peanut products such as peanut oil and peanut butter are more and more loved by people. In fact, the nutritional value of peanut oil is indeed as rich as peanut. With the deepening of research, scientists found that peanut oil is rich in unsaturated fatty acids, accounting for more than 75%, of which monounsaturated fatty acids exceed 50%. At the same time, the role of monounsaturated fatty acids is gradually understood by people. At present, scientists have mastered the knowledge that monounsaturated fatty acids can reduce blood cholesterol, prevent atherosclerosis and coronary heart disease, and reduce cardiovascular harm by 2 1%.
In addition, peanut oil also contains 13 vitamins and 26 mineral elements, rich in vitamin E and folic acid, as well as mineral elements such as zinc, calcium, phosphorus and iron. Each of these 26 elements is essential to the human body. Supplementing the intake of these nutrients through diet can enhance physical fitness and help improve the nutritional deficiency and malnutrition of Chinese residents.
For example, per 100g peanut oil contains 8.48mg of zinc, which is 37 times that of salad oil, 32.6 times that of corn oil and 7 times that of soybean oil. Zinc can promote children's brain development, activate brain cells of middle-aged and elderly people, and has a certain effect on delaying aging. In addition, scientists also found some phytoactive chemicals in peanut oil, including phytosterols, resveratrol, isoflavones, B- sitosterol, etc., all of which have important health care functions. Nutrition research has confirmed that phytosterol is a lipid compound, which is not absorbed by human body, prevents cholesterol absorption and can effectively prevent cardiovascular and cerebrovascular diseases. B- sitosterol has the effects of lowering cholesterol and preventing cardiovascular and cerebrovascular diseases and cancer.
Picking peanut oil for a healthy society
During holidays, it is easy for people to be surrounded by delicious food. At this time, we should pay more attention to the balance of diet and replenish the body with necessary energy. Nutritious peanuts and peanut oil are undoubtedly our best choice. However, readers should be reminded that if you choose to eat peanut oil as a simple and powerful support for health, not every peanut oil sold in the market has rich nutritional value. Some fake and shoddy products not only can't add vitality to the body, but are even harmful to health. When choosing peanut oil, we should not only look for the products produced by regular manufacturers, but also know how to judge. The main distinguishing means lies in the production process of oil. The leaching process will destroy the nutrition of peanuts, while pure physical pressing can completely retain the natural nutrition of peanuts. (Evening News)
Verification of China Nutrition Education Research Report;
Peanut oil is really good for health.
Recently, China Journal of Nutrition published an experimental report of Shandong University on the effect of peanut oil on the blood lipid level of middle-aged and elderly people in China.
Sixty-five healthy middle-aged and elderly people (40-60 years old) were selected in the experiment, and each person used four different recipes successively: a, basic diet, that is, original diet, more animal fat intake and salad oil for cooking; B, a low-fat and high-carbohydrate diet; C, peanut oil diet, using peanut oil instead of salad oil to reduce the intake of animal food; Peanut oil and peanut diet.
Experimental results: Compared with the basic diet, peanut oil diet rich in oleic acid, peanut oil plus peanut diet and low-fat diet reduced total cholesterol and harmful cholesterol. Professor Xu Guifa of Shandong University said, for example, Lu Hua, who participated in the experiment, this advanced squeezing technology can retain the active substances in peanuts to the maximum extent, such as fat-soluble vitamins, phytosterols, resveratrol, etc., and it also plays a beneficial role in the process of regulating blood lipids.
Peanut oil and olive oil have their own advantages, and peanut oil is more suitable for mass consumption.
Peanut oil and olive oil have become favorite edible oils for consumers at home and abroad. Its * * * is the same:
No cholesterol, high oleic acid content. Olive oil has the highest oleic acid content, up to 60%-84%. Peanut oil accounts for 42-68%, which is 2-3 times that of other vegetable oils such as soybean oil, sunflower oil and corn oil.
They are all squeezed into oil. Peanut oil and olive oil are both pressed to make oil, which ensures the safety, hygiene and pollution-free of refined oil.
The difference between the two is that olive oil is light and suitable for western tastes; Peanut oil has a strong aroma, which is more suitable for China people's traditional eating habits. The market price of olive oil is expensive, which is 10 times that of ordinary edible oil; Peanut oil is more than ten yuan a catty, which is acceptable to most urban residents.
Advanced nutritional oil sunflower seeds
Sunflower seed, also called sunflower seed, is the fruit of sunflower. Its nuts contain 30%-45% fat, up to 60%. Sunflower seed oil is golden in color, clear and transparent, and fragrant in smell. It is an important edible oil. It contains a lot of unsaturated fatty acids such as linoleic acid, which can promote the regeneration and growth of human cells, protect skin health and reduce the accumulation of cholesterol in blood. It is a kind of advanced nutritional oil.
Sunflower seed oil is rich in carotene, more than peanut oil, sesame oil and soybean oil. Therefore, it can reduce the concentration of serum cholesterol, prevent arteriosclerosis and vascular diseases, and is very suitable for hypertensive patients and middle-aged and elderly people.
Sunflower seed oil also contains more vitamin E, about 100- 120 mg per hundred grams. Therefore, it has a good effect of delaying the aging of human cells and maintaining youth. Regular consumption can strengthen the body and prolong life.
Sunflower seed oil also contains more vitamin B3, which is effective in treating neurasthenia and depression. It contains a certain amount of inorganic substances such as protein, potassium, phosphorus, iron, magnesium, etc., which is very effective in treating diabetes and iron deficiency anemia, and is of great significance for promoting the healthy growth of teenagers' bones and teeth. It contains linoleic acid, an essential fatty acid for human body, which is helpful for human development and physiological regulation, and also has a positive effect on preventing skin dryness and scale hypertrophy.
Sunflower seed oil also contains nutrients such as glucose and sucrose, and its calorific value is higher than that of soybean oil, peanut oil, sesame oil and corn oil, and it can produce 9.499 calories per gram. Its melting point is also low, suitable for human absorption, and the absorption rate can reach above 98%. In addition, it is slightly hot and fragrant. It is the best edible oil besides sesame oil.
Because sunflower seed oil is rich in nutrition and has many health functions for human body, it is known as "advanced nutritional oil". In recent years, it has been selling well in the international market and is deeply favored.
Want health? Eat peanut oil!
2003-6-6
At the beginning of the Spring Festival in 2003, the Great Hall of the People chose pure peanut oil with special flavor of Lu Hua as the oil for the state banquet. This not only further established the outstanding position of "Lu Hua" in high-quality peanut oil, but also aroused people's great concern about peanut oil, which triggered people's discussion on the nutritional value, health care function and the function of improving people's diet structure. Let's listen to the opinions of several famous nutritionists and medical experts.
Use peanut oil to reduce heart disease
A study by American Nutrition Society and Cincinnati Medical College shows that people who eat peanut oil have "two lows and one high": low blood lipid, low harmful cholesterol and high beneficial cholesterol. Another survey of 80082 women in the United States for several years found that monounsaturated fatty acids, the main component of peanut oil, are important cardioprotective factors for preventing coronary heart disease.
In the study of modern people's diet, the American Heart Association found that Greece, especially Crete, had the lowest incidence of cardiovascular diseases, while Finland and the United States had the highest incidence. The only significant difference between Greece and the other two countries is the different types of fat consumed by its residents. Studies have shown that monounsaturated fatty acids are consumed in large quantities in countries with low mortality from cardiovascular diseases. Professor Mao, a national expert with outstanding contributions, said that edible oil is mainly composed of saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids and trace elements. Nutritionists at home and abroad agree that judging the quality of an edible oil mainly depends on the content of monounsaturated fatty acids in the oil. The higher the content of monounsaturated fatty acids, the higher the nutritional value and health care function.
Among the main edible oils in China, peanut oil has the highest monounsaturated fatty acid content, reaching 48%, while the monounsaturated fatty acid content of corn oil, soybean salad oil, rapeseed salad oil, most blended oil and sunflower seed oil is only equivalent to1/3 ~12 of peanut oil. Polyunsaturated fatty acids are commonly found in corn oil, salad oil, sunflower oil and safflower oil.
There are two kinds of cholesterol: low density lipoprotein (LDL) and high density lipoprotein (HDL), which are also called "bad cholesterol" and "good cholesterol" respectively. The former is harmful to the human body, while the latter can remove cholesterol, transfer it to the liver and excrete it through the bile duct. Polyunsaturated fatty acids not only reduce the content of "bad cholesterol", but also reduce the content of "good cholesterol". Monounsaturated fatty acids can not only reduce the content of "bad cholesterol", but also significantly increase the content of "good cholesterol", thus preventing cholesterol deposition and reducing the incidence of cardiovascular diseases.
China's "longevity fruit" is American Toona sinensis.
Professor Xu Guifa, director of the China Nutrition Society and a member of the American Nutrition Society, said that in recent years, there has been a craze for eating peanuts and peanut oil in the United States. At the same time, American nutritionists introduced a series of peanut anti-aging achievements to residents. This verifies the rationality of the ancient peanut name "longevity fruit" in China. Their experiments on peanuts and peanut oil show that peanuts contain a variety of anti-aging components, especially five anti-aging components such as monounsaturated fatty acids, resveratrol, β phytosterol, folic acid and trace element zinc. These components play an important role in regulating human functions and preventing cardiovascular and cerebrovascular diseases.
Professor Xu said that there are great differences in the basic views of Chinese and American residents on peanuts. Many people in our country think that peanuts are easy to make people fat, and a research result of Harvard University proves that peanuts are the main content of dieters' diet, and peanut food is a daily food deeply loved by American residents.
A top two, a top three.
Professor Mao said that he and a famous restaurant host had done an interesting experiment, using pure peanut oil, common blended oil and salad oil to make the same dish. The results showed that the dosage ratio was 1∶2.5∶3 to meet the requirements of the same color, fragrance and taste. Peanut oil is simply a top two and a top three.
He told consumers that when switching from other edible oils to peanut oil, they must not make empirical mistakes. We usually use three or two, but now we can use one or two or five, which is economical and practical, and can reduce the body's intake of fat and prevent obesity.
Professor Mao quoted figures from China College of Preventive Medicine as saying that the zinc content in peanut oil is as high as 8.48 mg per 100 grams, which is 37 times that of salad oil, 0/6 times that of rapeseed oil and 7 times that of soybean oil. As we all know, zinc is an indispensable trace element for human body. Supplementing more zinc can enhance the body's disease resistance and delay the decline of brain cells and human functions. Children can eat more foods rich in zinc, which can stimulate appetite, promote physical development and promote intellectual development.
Squeeze raw materials and eat green
It is understood that there are two popular edible oil processing methods in China at present: one is leaching method, which requires solvent elimination, high-temperature refining, decoloration and deodorization in the production process, which will inevitably cause the loss of some nutrients. This method is used for most salad oils and blended oils. One is the squeezing method represented by Lu Hua, the first brand of peanut oil in China. The principle of this process is: the oil is separated from the raw materials by physical pressing, and no chemical substances are used to ensure the original flavor of the product, which is safe, hygienic and pollution-free.
Professor Mao said that the domestic peanut oil pressing technology has made a breakthrough. Luhua Texiang pure peanut oil, which adopts the core technology of 5S pure physical squeezing technology, has reached or exceeded the level of internationally renowned brand products in terms of color, taste and internal quality, and has been exported to more than a dozen countries and regions. It is a green food that ordinary people can safely eat.
People in Hangzhou may not know much about peanut oil. But when I arrived in Beijing, I found that peanut oil was really dazzling, and other edible oils were not easy to buy.
In fact, peanut oil was rarely seen in Beijing before 1998. With the enhancement of consumer rationality and the improvement of consumption level, peanut oil currently occupies a dominant position in Beijing edible oil market. Whether it is frying, frying, boiling, frying or cold salad, it is inseparable. Most famous restaurants and hotels use peanut oil.
Wang Ruiyuan, president and chief expert of Oil Branch of China Grain and Oil Association, believes that peanut oil has extremely high nutritional value, and its performance conforms to the eating habits of the orientals. Peanuts in China have obvious advantages in scale and quality in the world. What is certain is that peanut oil will become one of the main characters on the dining table of China people in a few years, because the healthy life of ordinary people really cannot be separated from it.
Look, how important peanuts and peanut oil are! (Zhejiang Daily)
Cooking oil, don't always stare at one food.
In the past two decades, people have consumed too many high-calorie foods, including fat, or improperly selected fat, which has led to high incidence of diseases such as overweight, obesity, arteriosclerosis, hyperlipidemia, hypertension and gallstones. However, there are different views on various edible oils in society. Faced with all kinds of edible oils on the market, the people are at a loss. So how should we treat these problems?
Edible oil has its own characteristics.
olive oil
It contains monounsaturated fatty acids, which is the highest among all edible oils. It has good effects of reducing low-density cholesterol (bad cholesterol) and increasing high-density cholesterol (good cholesterol), so it has the effects of preventing cardiovascular and cerebrovascular diseases and reducing cholecystitis and gallstones. Olive oil also contains vitamins A, D, E, K and carotene, which has a certain effect on improving digestive function, enhancing calcium deposition in bones and delaying brain atrophy. However, olive oil is expensive, tasteless and lacks attractive fat flavor, so most people in China don't like its taste very much.
Tea seed oil
Monounsaturated fatty acids are similar to olive oil, so they are called "Oriental olive oil". It is reported that the incidence and mortality of cardiovascular diseases among residents in a tea oil producing area are lower than those in other areas.
rap oil
It contains high monounsaturated fatty acids, so it has the effect similar to olive oil and is good for gallbladder. Rapeseed oil is the lowest price among all edible oils rich in monounsaturated fatty acids, so it is becoming more and more popular.
peanut oil
It is rich in oleic acid, lecithin, vitamins A, D, E, K and natural polyphenols with strong biological activity, so it has the functions of reducing platelet aggregation, reducing the levels of total cholesterol and bad cholesterol, and preventing arteriosclerosis and cardiovascular and cerebrovascular diseases. People think that eating too much peanut oil is easy to get angry, which is because arachidonic acid in peanut oil causes allergic reaction in human body.
Soybean oil
Rich in polyunsaturated fatty acids and vitamins E and D, it can reduce cardiovascular diseases, improve immunity, and increase weight for the weak and emaciated. Soybean oil contains more polyunsaturated fatty acids, so it is the most prone to rancidity among all kinds of oils. So when you buy it, you must choose something that has not been delivered for a long time and try to eat it fresh.
sunflower seed oil
Rich in essential fatty acids, linoleic acid and α -linolenic acid can synthesize DHA related to brain nutrition in vivo, and sunflower oil for pregnant women is beneficial to fetal brain development; Vitamins E and A contained in it have the functions of softening blood vessels, lowering cholesterol, preventing cardiovascular and cerebrovascular diseases, delaying aging, preventing dry eye, night blindness and dry skin. It also contains high polyunsaturated fatty acids, so it has the same precautions as soybean oil.
salad oil
It is the edible oil with the highest processing grade among vegetable oils. Basically, all impurities and waxes in vegetable oils have been removed, so the color is the lightest. Salad oil is suitable for frying, frying, frying and cold salad, which is beyond the reach of other edible oils.
sesame oil
Known as the "king of vegetable oil", it is rich in a variety of unsaturated fatty acids, protein, calcium, phosphorus, iron, lecithin, vitamins A, D and E, and has the functions of scavenging free radicals, improving immunity, delaying aging, preventing constipation, coronary heart disease, diabetes, premature gray hair and beauty beauty. Chinese medicine believes that patients with emphysema can relieve cough symptoms by drinking a little sesame oil before going to bed and getting up the next day.
lard
It contains high saturated fatty acids, and eating too much can easily lead to hyperlipidemia, fatty liver, arteriosclerosis and obesity. But don't be afraid to eat it, because the cholesterol it contains is the raw material for the human body to make steroid hormones, adrenocortical hormones, sex hormones and synthesize vitamin D by itself. The α -lipoprotein in lard can prolong the life of animals, which is lacking in vegetable oil. (Professor Jiang Jia from Shanghai Center for Disease Control and Prevention)

Edible oil is a necessity of people's life, and it is an important food that provides heat energy and essential fatty acids for human body and promotes the absorption of fat-soluble vitamins. There are many kinds of edible oils on the market, and there are different opinions about which oil to eat. If we understand the nutritional value of edible oil and its influence on human health, it will help people to choose edible oil correctly. Edible oil is a triglyceride mixture composed of glycerol and various fatty acids, which can be divided into saturated fatty acid oils, such as lard, butter, sheep oil and other animal oils; Monounsaturated fatty acid oils, such as peanut oil and rapeseed oil; Polyunsaturated fatty acids such as sunflower oil, soybean oil, corn oil, cottonseed oil, sesame oil and linseed oil.
Animal oil mainly contains saturated fatty acids such as cholesterol, palmitic acid, myristic acid and lauric acid. These fatty acids are also needed by the human body. If it can't be obtained from external oil, the human body can use the sugar in the body to synthesize it. This saturated fatty acid will raise cholesterol in the blood.
Vegetable oil mainly contains polyunsaturated fatty acids and monounsaturated fatty acids such as stigmasterol and sitosterol. Polyunsaturated fatty acids can lower cholesterol, while monounsaturated fatty acids have no effect on cholesterol. Some unsaturated fatty acids can be synthesized from saturated fatty acids in human body, but linoleic acid, linolenic acid and arachidonic acid cannot be synthesized in human body and must be taken from food. Therefore, nutritionists call these three unsaturated fatty acids "essential fatty acids" for human body. Animal fat and cream are rich in vitamin A and vitamin D, which are closely related to human growth and development. Vegetable oil is rich in vitamin E and vitamin K, which is closely related to the function of blood and reproductive system.
There are two indicators to measure the nutritional value of oil, one is the content of unsaturated fatty acids; The second is the content of essential fatty acids. Vegetable oil contains these two fatty acids, which are generally higher than animal oil. The more unsaturated fatty acids, the better for human health. Essential fatty acids are important raw materials for prostaglandin synthesis, which can promote the synthesis of carbon and lipid in the body, update the structure of cell biofilm, turn cholesterol into bile hydrochloric acid, and prevent arteriosclerosis from depositing on the blood vessel wall. For middle-aged and elderly people and patients with cardiovascular diseases, it is good for your health to eat less animal oil and give priority to vegetable oil. For growing teenagers, there is no need to limit animal oil too much. Generally speaking, the dosage standard of edible animal and vegetable oil is 3: 7.
The experiment shows that the "bodybuilding nutrition oil" made of 50% corn oil, 30% sunflower oil and 20% peanut oil is rich in unsaturated fatty acids and essential fatty acids, and contains trace elements such as sitosterol, lecithin, carotene, vitamins A, B, D, E, zinc and selenium. The digestion and absorption rate of "Fitness Nutritive Oil" is as high as 98%, which is helpful to human growth and physiological regulation, improving brain function, inhibiting the absorption of food cholesterol by human intestine, regulating the ability of liver to synthesize cholesterol, and preventing and treating cardiovascular and cerebrovascular diseases. Has the effects of resisting arteriosclerosis, lowering serum cholesterol, and preventing hypertension, coronary heart disease and cell aging.
How to choose healthy edible oil
Red Net "Font: Large, Medium and Small"
What kind of oil is more beneficial to health? What kind of oil is the best "healthy oil" for our health? Because ordinary consumers don't know much about the fatty acid composition ratio of edible oil and its different effects on human body, they are at a loss and at random when choosing it. Many people mistakenly think that edible oil is just a condiment.
According to nutrition experts, in fact, what kind of oil we eat every day-what kind of fat we eat-is very important to our health. Among the seven nutrients that people consume every day, such as protein, fat, carbohydrates, vitamins, minerals, cellulose and water, fat accounts for 35% of the total calories, and more than 76% of the total fat comes from the oil we eat every day. The basic components of edible oils and fats are mainly saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. According to the international nutrition standard of fatty acid content: if the content of saturated fatty acid exceeds 12%, too much saturated fatty acid will produce fat accumulation in human body, which will cause abnormal blood lipid level and induce serious cardiovascular and cerebrovascular diseases such as hyperlipidemia, hypertension and atherosclerosis; Monounsaturated fatty acid (oleic acid) is an important fat to maintain normal blood lipid level and reduce the occurrence of cardiovascular and cerebrovascular diseases. If its content reaches more than 70%, it can regulate blood lipids, and reduce "bad" low-density lipoprotein cholesterol in blood without reducing "good" high-density lipoprotein cholesterol, which is very beneficial to the health of heart, brain, kidney and blood vessels. Linoleic acid and linolenic acid in polyunsaturated fatty acids are essential fatty acids for human body. If the ratio of ω-3 linolenic acid to ω-6 linoleic acid is close to the ideal level of 1∶4, it will be very beneficial to human body. However, if the linoleic acid content is higher than 15%, it will induce many diseases, especially tumor diseases. However, the content of ω-3 linolenic acid should be above 2.5%, and daily intake of 1g is very beneficial to human body. Experts pointed out that the quality of edible oil mainly refers to whether the proportion of fatty acids in oil is reasonable. Consumers are advised to pay attention to the following six points when choosing:
1, away from oils with high saturated fatty acids. Generally, animal fat contains more saturated fatty acids, so it is not advisable to eat more animal oil (such as pig, cattle and sheep oil); 2. Choose oils and fats with monounsaturated fatty acids content above 70%, such as wild tea oil and olive oil; 3. Choose oils rich in ω-3 linolenic acid, such as wild tea oil and walnut oil; 4. Avoid eating oils with ω-6 linoleic acid content exceeding 15%, such as safflower oil, sunflower oil, peanut oil, sesame oil, grape seed oil and corn oil. 5. The ratio of ω-6 linoleic acid to ω-3 linolenic acid in polyunsaturated fatty acids is preferably 4 ∶1; 6. Does it contain vitamin E? Vitamin E is an antioxidant, which can reduce the formation of oxidized LDL (low density lipoprotein cholesterol) and reduce the possibility of atherosclerosis.
When choosing edible oil, the most noteworthy thing is the nutritional components. Professor Du Shoujun, consultant of the National Food and Nutrition Expert Advisory Committee and Peking Union Medical College, said that monounsaturated fatty acids in the diet are negatively correlated with the occurrence and mortality of cardiovascular and cerebrovascular diseases such as "three highs". In order to achieve the goal of balanced diet, patients with cardiovascular diseases such as "three highs" should choose edible oil that suits them. The FDA (American Food and Drug Administration) announced in June, 2004 1 65438+1October1day that people consume 23 grams of olive oil every day, and monounsaturated fatty acids in it can reduce the incidence of coronary heart disease.
