Some scientific studies at home and abroad show that human aging is related to the peroxidation of unsaturated fatty acids in the body, and the peroxidation of unsaturated fatty acids is related to the action of free radicals. Free radicals with high chemical activity can make unsaturated fatty acids over-oxidized, make cell function mutate or decline, cause tissue proliferation and necrosis, and produce fatal diseases. Lipid peroxidation is the devil of human health, but the culprit is free radicals. As long as free radicals are removed, cells can grow and develop normally, and live a long and healthy life.
Commonly used antioxidants are vitamin C and vitamin E, which can effectively prevent the over-oxidation of unsaturated fatty acids. Recently, Japanese researchers have shown that polyphenols in Tieguanyin can prevent excessive oxidation; Purine alkaloids can indirectly scavenge free radicals, thus achieving the purpose of delaying aging.
Anti-cancer effect of Ertieguanyin
Cancer is an "incurable disease" that seriously threatens people's health today. Therefore, in recent years, the anti-cancer research of tea has aroused great interest and concern. A few years ago, it was reported that the esophageal cancer of Shanghai residents decreased year by year because of drinking tea, so the fact that drinking tea can prevent cancer caused great repercussions all over the world. Nowadays, drinking tea to prevent cancer has been recognized by the world, and Tieguanyin is the best anticancer effect in tea.
As early as 1983, Professor Tuonan Okuda of Okayama University in Japan had screened out the anticancer effects of dozens of plant polyphenols. The results showed that catechin (EGCG) had strong anticancer activity. Another scientist believes that Tieguanyin tea polyphenols are the main active ingredient in the study of confirming Tieguanyin's anti-mutation. In the study of chemical carcinogenesis, the preventive effect of Tieguanyin tea polyphenols has been affirmed. In addition, vitamin C and vitamin E in Tieguanyin can block the synthesis of nitrosamines, which plays a great role in the prevention and treatment of cancer.
Anti-arteriosclerosis effect of Santieguanyin
1999 may 3 1, at the fourth symposium on oolong tea and health held in Tokyo, Japan, Vice President Chen Ling of Fujian Institute of Traditional Chinese Medicine reported that they took 25 patients with hyperlipidemia and obesity as clinical observation objects to explore the effect of drinking oolong tea Tieguanyin on inhibiting the oxidation of low-density lipoprotein in blood and improving blood lipid metabolism. Studies have proved that tea polyphenols and vitamins in Tieguanyin can inhibit the oxidation of low-density lipoprotein in blood. Dr. Masahiko Hara of Mitsui Institute of Agriculture and Forestry in Japan has also confirmed in many years' research that tea polyphenols can not only reduce cholesterol in blood, but also significantly increase the ratio of high-density lipoprotein to low-density lipoprotein in blood. Caffeine can relax blood vessels, speed up breathing, reduce blood lipids, and has a certain effect on the prevention and treatment of cardiovascular and cerebrovascular diseases such as coronary heart disease, hypertension and arteriosclerosis.
According to the survey of farmers in Anxi Tea Township 1080 of Fujian Medical University, the incidence of not drinking Tieguanyin tea is 3. 1%. Occasionally drinking alcohol is 2.3%; Drinking for more than 3 years is 1.4%. It can be seen that people who often drink Tieguanyin have lower incidence of coronary heart disease than those who don't drink Tieguanyin.
The preventive and therapeutic effects of Si Tieguanyin on diabetes mellitus
Diabetes is a worldwide disease. At present, about 200 million people in the world suffer from diabetes, and more than 30 million people in China suffer from diabetes. Diabetes mellitus is a chronic progressive disease with disorder of glucose metabolism. The typical clinical manifestations are "three more and one less", that is, drinking more, urinating more, eating more and wasting away, and feeling weak all over. This disease is called "diabetes" in Chinese medicine and belongs to the category of hot and humid heat. The main cause of the disease is the lack of polyphenols in the body, such as vitamin B 1, pantothenic acid, phosphoric acid, methyl salicylate and so on. , make the glucose metabolism disorder, the blood sugar in the body rises sharply, and the metabolism is weakened.
The clinical experiments of Nana Ogawa Takeichiro, a Japanese doctor of medicine, confirmed that drinking tea regularly can replenish vitamin B 1, pantothenic acid, phosphoric acid, methyl salicylate and polyphenols in human body in time, which can prevent the occurrence of diabetes. For patients with moderate and mild diabetes, blood sugar and urine sugar can be reduced to very little or completely normal; For patients with severe diabetes, it can reduce blood sugar and urine sugar and relieve various main symptoms.
Weight loss and bodybuilding function of Wu Tieguanyin
Obesity is a nutritional disorder accompanied by the continuous improvement of people's living standards, which is caused by excessive nutrient intake or insufficient use of energy stored in the body. Obesity not only brings inconvenience to people's daily life, but also causes cardiovascular diseases and diabetes.
During the period of 1996, Fujian Institute of Traditional Chinese Medicine conducted a study on the slimming effect of drinking Tieguanyin on 102 adult simple obese men and women. Studies have shown that Tieguanyin contains a lot of tea polyphenols, which can not only improve the function of lipolytic enzyme, but also promote the metabolic activity of neutral lipase in tissues. Therefore, drinking Tieguanyin can improve the body shape of obese people, effectively reduce the subcutaneous fat and waist circumference of obese people, and thus lose weight.
People's Hospital of Quanzhou City, Fujian Province used Tieguanyin slimming tea to treat 164 obese patients, taking slimming tea 12 ~ 14g every day, 15 days as a course of treatment. After two courses of observation, the patients' blood lipid, triglyceride and cholesterol decreased obviously, and their weight also decreased, and the total effective rate reached over 70%.
The role of Liutieguanyin in the prevention and treatment of dental caries
It is generally believed that there are two main diseases that harm people's teeth, one is dental caries and the other is periodontitis. Dental caries, commonly known as tooth decay, is a common and frequently-occurring disease in dentistry. There are many reasons for dental caries, one of which is that teeth are poorly calcified, the texture is not hard enough, and it is easy to be damaged. Drinking tea can protect teeth, which has been used for a long time in ancient China. Su Dongpo in Song Dynasty said in Tea Theory: "Gargling with strong tea can not only relieve annoyance, but also strengthen teeth and eliminate smoking addiction." According to modern scientific analysis, Tieguanyin is rich in fluorine, but the fluorine content in general food is very small. About 40% ~ 80% fluoride in Tieguanyin is dissolved in boiling water, which is easy to combine with calcium in teeth and form a layer of calcium fluorophosphate on the surface of teeth, which plays a role in preventing acid and caries.
In Japan, the dental caries rate of school-age children in two neighboring villages was investigated. The results show that drinking Tieguanyin has a good preventive and therapeutic effect on dental caries. Every child who goes to school drinks a cup of Tieguanyin every day. If the fluorine content is 0.4 mg, for one year, half of the children suffering from dental caries will be cured. According to Japanese statistics, there are 65,438+000 primary school students suffering from dental caries. After drinking Tieguanyin, 55% of the students' dental caries were obviously relieved. It can be seen that drinking Tieguanyin has a preventive effect on people without dental caries and a therapeutic effect on people with dental caries.
Seven, sterilization and dysentery.
Tieguanyin has long been used to treat dysentery and stomachache in Anxi. There are also many records about the treatment of bacillary dysentery, dysentery, dysentery, acute enteritis and acute gastritis with tea in ancient medical books in China. Why can Tieguanyin play a role in sterilizing and stopping dysentery? Mainly tea polyphenols. Because tea polyphenols enter the gastrointestinal tract, it can relax the nervous function of the intestine and relieve the intestinal movement; At the same time, it can coagulate the intestinal protein, because the bacteria themselves are composed of protein. When tea polyphenols meet bacterial protein, bacteria will die immediately, which plays a role in protecting gastrointestinal mucosa, so it has the effect of treating enteritis.
Eight, the role of clearing heat and reducing fire
Tea is a good drink for heatstroke prevention and cooling. Li Shizhen's "Compendium of Materia Medica" said: "Tea is bitter and cold, but ……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………. "In the dog days of midsummer, it's cool and hot. Drinking a cool Tieguanyin or a hot Tieguanyin will make you cool physically and mentally, and bring forth body fluid to relieve summer heat. This is because tea soup contains tea polyphenols, sugars, amino acids, pectin, vitamins and so on. It reacts chemically with saliva in the mouth to moisten the mouth, so it can play the role of promoting fluid production and quenching thirst. At the same time, due to the caffeine in Tieguanyin, a lot of energy is released from the pores of human skin. It is reported that drinking a cup of hot tea can sweat through human skin pores, which is equivalent to 50 times of this cup of tea, so it can make people feel cool and relieve summer heat.
Nine, refreshing.
It is almost known that drinking tea can refresh you. There are many medical books in China in the past dynasties, and all the literati and monks in the past dynasties waved their wonderful pens and praised the refreshing and beneficial effects of tea. Bai Juyi's poem "To the Thirteen Kings of the East" said: "Chi Pan's moon is hand in hand, and bamboo is blowing. Drive away the sorrow and know the strength of the wine, and break the sleep and see the tea. " This poem clearly mentions the efficacy of tea in refreshing and breaking sleep. Su Dongpo's poem said: "Make thirty cups of tea, regardless of taste, and pack laymen with monks who beat sand people." He said that he would give the tea to Bao Jushi and let him drink it to avoid falling asleep during meditation. Drinking tea can be beneficial to thinking, so it is loved by people, especially some writers, poets and other mental workers. For example, Balzac, a great French writer, Han, a Chinese-American woman writer, and Yao, a famous writer in China, all like drinking tea to help their writing.
Tieguanyin can refresh the mind, and its function mainly lies in caffeine in tea. Caffeine can excite the central nervous system, improve thinking and improve efficiency. Therefore, drinking tea can break sleep, refresh and relieve boredom, clear the mind, improve thinking, and significantly improve oral defense ability and mathematical thinking response. At the same time, Tieguanyin contains polyphenols and other compounds, which counteracts the adverse effects of pure caffeine on human body. This is also one of the important reasons for the long history, enduring and continuous development of tea drinking.
Effects of ten Tieguanyin on sobering up and quitting smoking
It is also a well-known fact that tea can sober up and fight against cigarettes. Wang Yangming, a philosopher in the Ming Dynasty, famously said, "Just like being drunk, you need tea to sober up", which shows that our people have long recognized the efficacy of drinking tea to sober up. The ancients often "drown their sorrows by drinking" and "sober up with tea". Liu Yuxi, a poet in the Tang Dynasty, was drunk one day and remembered that Bai Juyi had "six teas" to sober up, so he sent someone to give him some tea to sober up, which was passed down as a tea affair by later generations. The main component of wine is alcohol, and a glass of wine contains alcohol 10% ~ 70%. Tieguanyin tea polyphenols and ethanol (the main component of wine) can offset each other, so drinking tea can relieve alcohol.
Tieguanyin can not only sober up, but also fight against cigarettes. Because Tieguanyin contains a phenolic acid substance, it can precipitate nicotine in tobacco and excrete it. At the same time, caffeine in Tieguanyin can improve the liver's ability to metabolize drugs, promote blood circulation, expel nicotine from human blood from urine, and alleviate and eliminate the side effects caused by nicotine. Of course, this effect is not only the single effect of caffeine, but also the synergistic effect of tea polyphenols, vitamin C and other ingredients.
Eleven detoxification, digestion, tired eyes, heart, everything.
Tea has been recognized as the best healthy drink. People's long-term practice of drinking tea has fully proved that drinking tea can not only improve nutrition, but also prevent and treat diseases. As early as the Western Han Dynasty, there was a record in Shennong's Classic of Materia Medica that "Shennong tasted a hundred herbs and encountered 72 poisons every day, so he eliminated them with tea". It shows that the detoxification effect of tea has been discovered in Shennong period. Regarding the digestion effect of tea, the book "Seeking Truth from Materia Medica" makes it very clear: in terms of efficacy, there are as many as 19, and most people call it "digestion". In classic works such as Tea Classic, Tea Spectrum and China Pharmacy Dictionary, it is recorded that tea has the functions of "eliminating fishy meat, clearing the heat of highland barley" and "resolving food stagnation". The functions of degreasing and improving eyesight of tea have been loved and respected by people since ancient times. Dong Bo Miscellaneous Notes and Edited by Herbology Society have the words of "relieving greasy food, cattle and sheep poison" and "improving eyesight".
With the passage of time, people didn't know the structure and properties of flavonoids in tea until the end of 19. More than a hundred years later, with the development of science and the continuous improvement of chemical determination methods, scientists found that this mixture contains more than ten kinds of compounds, which are very complex in nature and have the functions of regulating human metabolism, enhancing vascular elasticity, sterilizing and detoxifying. Later medical research also showed that tea contains caffeine, tea polyphenols, vitamins, aromatic substances and other components that are beneficial to human health. Drinking tea can not only quench thirst, relieve fever, detoxify, diminish inflammation, help digestion, but also improve eyesight, clear heart and cheer up. Menstruation and other medical and health care functions. Tieguanyin, as a famous tea in the world, must have these characteristics of ordinary tea. As the song "To You Three Cups of Tieguanyin" says: "Tourists from afar pass by the tea forest and worship you three cups of Tieguanyin. One cup of clear eyes, two cups of pure heart, and three cups of green tea nourish the heart and refresh the mind. I have never tasted Anxi Tieguanyin in my life, nor am I a real tea taster. " Singing has become a household name and spread all over the country.
Beauty, weight loss, anti-aging, cancer prevention and intelligence enhancement.
In recent years, with the improvement of living standards, people's awareness of health care has been continuously enhanced. Drinking tea requires not only good tea, but also health-care tea that is beneficial to health and longevity. In this regard, medical experts have studied the effects of Tieguanyin tea on various organs and functions of the human body by using the special ingredients contained in Tieguanyin tea. The role of research work. The results show that Tieguanyin not only has the above medical and health care functions, but also has obvious unique functions such as preventing dental caries, reducing blood fat, anti-inflammatory, anti-allergic, beautifying, losing weight and delaying aging. Tieguanyin has these special effects: first, the crude catechin group of Tieguanyin? He Zhong has the strongest antioxidant activity, and it contains the highest amount of EGCG, which can remove the reactive oxidation molecules in cells and improve the damage or influence caused by reactive oxygen species, thus protecting the human body from aging diseases (such as dementia). Secondly, compared with other teas, the contents of Mn, Fe, F, K, Na (k/Na) in Tieguanyin are higher than those in other teas, and the ratio of k/Na is high, so it has a good curative effect on patients with diabetes and hypertension. 3. Among oolong tea, green tea, black tea and scented tea, Tieguanyin in oolong tea has the highest fluorine content. At the same time, the fluorine content of Tieguanyin is much higher than that of ordinary food. Fluorine is the main medium of bone structure, which has a significant effect on preventing and treating dental caries and osteoporosis in the elderly. Fourthly, compared with hairy crabs and daffodils, Tieguanyin has the richest kinds of aromatic substances and the highest content, which constitutes the characteristics of Tieguanyin's long fragrance. These scents have positive effects on pleasure, health preservation and health care. 1979 and 1984, there were two "Oolong Tea Fever" in Japanese market. Tieguanyin was once popular all over Japan and has become synonymous with oolong tea, known as "beauty tea" and "slimming tea".
However, drinking Tieguanyin tea can prevent cancer and increase wisdom, but it is not a little-known thing. Modern medical research shows that Tieguanyin has a high selenium content, which ranks among the top six teas and is also higher than the general oolong tea (such as Narcissus and Huang Dan). Selenium is a component of glutathione oxidase, which can stimulate the resistance of immune protein and antibody diseases and inhibit the occurrence and development of cancer cells. According to Fujian Tea 1998, British scientists have found that the pH of human brain fluid is related to IQ. Within the allowable range of body fluid pH, IQ is low when acidity is high and high when alkalinity is high. Tea is an alkaline drink. Drinking tea regularly, especially Tieguanyin tea, can adjust the acid-base balance of human body and improve people's IQ. This is due to the high content of vitamins, caffeine, amino acids, minerals and tea polyphenols in Tieguanyin, which is closely related to brain development. Vitamins have the functions of strengthening the brain, improving eyesight and improving intelligence. Caffeine can increase the content of AMP (AMP is the synthetic raw material of ATP, which is the energy needed for brain tissue activities), thus making brain cells flourish. Amino acids, minerals and tea polyphenols have a certain protective effect on brain function and have a good influence on human intelligence. Therefore, drinking Tieguanyin regularly has a positive effect on preventing cancer, increasing intelligence and benefiting the brain.
